Publication Acanthamoeba keratitis and acanthamoeba conjunctivitis: A case report(Iranian Scientific Society Medical Entomology, 2020-04-01) Alver, Oktay; Baykara, Mehmet; Yuruk, Merve; Ülkü Tüzemen, Nazmiye; ALVER, OKTAY; BAYKARA, MEHMET; TÜZEMEN, NAZMİYE ÜLKÜ; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Mikrobiyoloji Anabilim Dalı; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı; 0000-0002-5555-1649; AAA-5241-2021; ABI-7051-2020; CGE-2103-2022Acanthamoeba species are vision-threatening agents by causing cornea infections known as Acanthamoeba keratitis. A 5 year-old kid with the complaints of erythema, eyelid edema, inflammation, limitation of eye movements in the right eye, and having no history of wearing contact lenses or trauma, was diagnosed of Acanthamoeba conjunctivitis through laboratory examinations in the Ophthalmology clinic. The visual sharpness of the patient improved after the treatment. A 44 year-old female patient suffering from pain, stinging, irritation, and inability to see in the left eye with the history of wearing contact lenses or trauma was diagnosed of Acanthamoeba keratitis through laboratory examinations. The agent was isolated and identified as "A. castellam" in the Genotype "T2". Examination of the left eye on the 15th day of treatment indicated that all complaints disappeared except for the cataract originated visual loss. However, the first diagnosis of Acanthamoeba keratitis appeared in the literature on a case with no history of wearing contact lenses and trauma it is found to be attention grabbing. We think that Acanthamoeba should not be ignored among microbial agents that cause eye infection with or without trauma and contact lens usage history.Item Ağrılı göze sahip terminal glokom olgularında siklokrioterapi(Uludağ Üniversitesi, 2014-11-21) Baykara, Mehmet; Başyaka, Kevser; Yayla, Uğur; Budak, Berna Akova; İncebıyık, İlker; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.Siklokriyoterapi non-invaziv ve göreceli olarak uygulaması kolay bir yöntemdir. Bu çalışmada ağrılı göz nedeniyle siklokriyoterapi uygulanmış hastalarda uygulamanın etkinliği ve komplikasyon gelişme oranları araştırıldı. Uludağ Üniversitesi Tıp Fakültesi Göz Hastalıkları Kliniği’nde Ocak 2012 –Şubat 2014 tarihleri arasında siklokriyoterapi uygulanmış olan 38 hastanın 39 gözü retrospektif olarak incelendi. Hastaların yaş ortalaması 67,5 ±10.6 idi. Otuz bir göz neovasküler glokom tanısı almıştı. Yedi göz son dönem primer açık açılı glokom, 1 göz açı kapanması glokomu tanısı almıştı. Tedaviyi takiben ortalama göz içi basıncı düşüşü primer açık açılı glokomda 9,2 ±14.3 mm Hg iken, neovasküler glokom grubunda 14.1±14.7 mm Hg idi. Göz içi basınç kontrolü tüm gözlerin sadece 17’sinde (% 41) sağlanabilmişti, primer açık açılı glokomu grubunda 1 gözde (% 14), neovasküler glokom grubunda 13 gözde (% 41) gib kontrolü sağlanmıştı. Ağrılı gözlerin % 79 ’unda tedaviyi takiben rahatlama sağlanmıştı. Takiplerde hiçbir hastada ftizis bulbi ya da hipotoni gelişmedi. Siklokriyoterapinin çeşitli glokom türlerinde basınç kontrolü olmadan da iyi ağrı kontrolü sağladığı sonucuna varabiliriz.Item Benign neonatal hemangiomatosis with conjunctival involvement - Report of a case and review of the literature(Acta Dermato-Venereologica, 2002) Başkan, Emel Bülbül; Sarıcaoğlu, Hayriye; Baykara, Mehmet; Tunalı, Şükran; Uludağ Üniversitesi/Tıp Fakültesi/Dermatoloji Anabiilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Oftalmoloji Anabilim Dalı.; 0000-0002-0144-3263; AAH-1388-2021; 6602518817; 23093006700; 6603722836; 7004191748Hemangiomas are the most common tumours of infancy. When limited to the skin, multiple lesions have a benign course and excellent prognosis but in cases of visceral involvement, the morbidity and mortality rates are high. We report a rare case of a female infant with benign neonatal hemangiomatosis who had dramatic conjunctival involvement. The spectrum of neonatal hemangiomatosis is reviewed, highlighting the importance of differentiation of the two extremes of this disorder.Item Bimanual microincisional phacoemulsification combined with viscocanalostomy plus deeper sclerectomy(Sage Publications, 2009) Timuçin, Özgür Bülent; Baykara, Mehmet; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; ABI-7051-2020; 23093006700PURPOSE. The aim of the study was to evaluate the safety and effectiveness of a new technique, two-site bimanual microincisional cataract surgery combined with viscocanalostomy plus deeper sclerectomy (two-site bimanual MICS-VC-DS), in patients with cataract and glaucoma. METHODS. Noncomparative, interventional case series. From December 2005 to October 2007, a consecutive series of 12 patients (12 eyes) with uncontrolled primary open angle glaucoma (POAG) and cataract have undergone two-site bimanual MICS-VC-DS. Postoperative evaluation included visual acuity (VA), intraocular pressure (IOP), average retinal nerve fiber layer (RNFL) thickness measurement, and gonioscopic, biomicroscopic, and funduscopic examination. Paired-samples t test was used. A p value of <0.05 was taken as significant. RESULTS. The mean duration of follow-up was 14.6 months (SD 5.8). At 9 months, mean IOP was 17.0 (SD 4), the mean IOP reduction was 13.2 mmHg (SD 5.86). At 9 months post-surgery, the complete success rate was 75%. Qualified success was achieved in 100% of patients. At 9 months, the mean number of antiglaucoma medications was 0.58 (SD 1.24) (p<0.05). Visual acuity improved by a mean value of 2.8 lines. Average RNFL thickness did not change significantly during the follow-up period (p=0.781). CONCLUSIONS. Two-site bimanual MICS-VC-DS appears to be an effective and safe procedure with quick visual rehabilitation, acceptable mid-term IOP control, and the advantage of having fewer complications.Item Capsular block syndrome in a case with excessive cortical remnants(Slack Inc, 2003) Baykara, Mehmet; Ertürk, Haluk; Özçetin, Hikmet; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; ABI-7051-2020; 7004578592; 7003716972; 6603402155Ten days after cataract extraction with phacoemulsification and in-the-bag acrylic intraocular lens implantation, capsular block syndrome developed in the right eye of a 62-year-old man. Aspiration of the swollen cortical remnants resulted in resolution of the capsular block.Item A clinical comparison of dynamic contour tonometry versus goldmann applanation tonometry(Slack, 2010) Yalçınbayır, Özgür; Baykara, Mehmet; Atasoy, Aydın; Özçetin, Hikmet; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; ABI-7051-2020; AAH-6625-2021; 8702056700; 23093006700; 45360963500; 6603402155BACKGROUND AND OBJECTIVE: To compare the intraocular pressures (IOP) obtained with dynamic contour tonometry (DCT) and Goldmann applanation tos.nometry (GAT) and to determine the dependency of both devices on corneal structure. PATIENTS AND METHODS: One hundred forty eyes of 70 patients were included. Cases with corneal pathologies, former glaucoma diagnosis, and systemic diseases were excluded. All eyes underwent measurements of central corneal thickness (CCT) and corneal curvature. IOP measurements were obtained with GAT and DCT. The agreement of measurements was statistically analyzed. RESULTS: The correlation of IOP values obtained with DCT and GAT was statistically significant. The mean DCT values were 0.46 +/- 2.55 mm Hg higher than those of GAT, but this difference was statistically insignificant. Bland-Altman plots showed reasonable inter-method agreement between DCT and GAT measurements. GAT readings were significantly affected by CCT, but DCT measurements were affected by age and corneal curvature. CONCLUSION: DCT is a reliable method of assessing IOP and is less dependent on central corneal thickness. This new technology may be a promising step forward in the management of glaucoma. Further studies are required to validate these observationItem Comment on “Comparison of anterior segment optical coherence tomography bleb grading, moorfields bleb grading system, and intraocular pressure after trabeculectomy”(Lippincott Williams & Wilkins, 2017-10) Özçetin, Hikmet; Ermerak, Başak Can; Baykara, Mehmet; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; ABI-7051-2020; 57201270833; 7004578592Item Comparing the ocular surface effects of topical vancomycin and linezolid for treating bacterial keratitis(Taylor & Francis, 2015-06-01) Budak, Berna Akova; Baykara, Mehmet; Kıvanç, Sertaç Argun; Yılmaz, Hakan; Çiçek, Serhat; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; 0000-0003-0995-5260; 0000-0002-0932-6977; AAH-6518-2021; ABE-3033-2020; ABI-7051-2020; 55370489800; 23093006700; 47861204900; 57188580909; 57188593392Background: Vancomycin is the gold standard in combination therapy for severe and resistant gram-positive keratitis and in particular for Methicillin-resistant Staphylococcus aureus (MRSA) infections. The aim of this study was to report the ocular surface toxicity and scoring in patients whose treatment shifted to topical linezolid/ceftazidime from topical vancomycin/ceftazidime due to their vancomycin intolerance. Methods: A retrospective, interventional case series of bacterial keratitis was treated with topical linezolid (one drop of 0.2% solution per eye), administered hourly until epithelization and then gradually decreased. The number and extent of punctate epithelial erosions were noted across the entire surface of the cornea. Ocular discomfort was assessed by means of (a) patient-reported pain upon instillation of the medication (vancomycin/linezolid), (b) reported burning sensation between doses and (c) reported foreign-body sensation. No ocular surface toxicity related to linezolid use was noted. Patients were followed for at least 2 months after treatment between April and December 2013. Results: Of the seven patients included in the study (age range: 2-88 years; five females, two males), complete epithelization and resolution was achieved in five patients. One patient was treated with linezolid after penetrating keratoplasty. The second culture of another patient with impending perforation despite linezolid/ceftazidime therapy yielded Fusarium spp., so he underwent tectonic keratoplasty. The mean ocular surface score was 9.4 +/- 1.6 during vancomycin treatment and 5.9 +/- 1.3 during linezolid treatment after discontinuation of vancomycin. The topical linezolid score was significantly lower (p = 0.027). Conclusions: Topical linezolid may be better tolerated, according to the mean ocular surface score, than topical vancomycin by some patients and can be considered an alternative for patients who do not well tolerate vancomycin.Item A comparison of esmolol and dexmedetomidine for attenuation of intraocular pressure and haemodynamic responses to laryngoscopy and tracheal intubation(Lippincott Williams & Wilkins, 2008-06) Yavaşçaoǧlu, Belgin; Kaya, Fatma Nur; Baykara, Mehmet; Bozkurt, Merlin; Korkmaz, Serdar; Uludağ Üniversitesi/Tıp Fakültesi/Anesteziyoloji ve Reanimasyon Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; AAG-9356-2021; AAI-8213-2021; AAI-8213-2021; 6602742300; 7003619647; 23093006700; 16202046200; 24171259800Item Corneal sensitivity and ocular surface changes following preserved amniotic membrane transplantation for nonhealing corneal ulcers(Springernature, 2003-03) Doğru, Murat; Yıldız, Meral; Baykara, Mehmet; Özçetin, Hikmet; Ertürk, Haluk; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; 7006540932; 35791194600; 23093006700; 6603402155; 7003716972In summary, we found that AMT can be helpful for the treatment of epithelial defects and stromal ulcers. We came to learn that cases with total limbal deficiency or extensive ocular surface inflammation may not be cured with AMT alone. AMT provides improvement of corneal sensitivity, tear film stability and impression cytology parameters. However, the entire mechanism of the healing effect of amniotic membrane is still unknown. A recent experimental study revealed that amniotic membrane transplantation vs tarsorraphy in murine HSV-1 stromal keratitis resulted in improvements in substance-P-related corneal nerve fibres in eyes treated with amniotic membrane, but not in eyes treated with tarsorraphy. We think that prospective, controlled, comparative studies of corneal ulcers treated by, for instance, tarsorraphy or other modalities should be performed to investigate whether the beneficial changes of amniotic membrane transplantation are greater or lesser than the changes that might have been observed by an alternative treatment. In this study, we tried to point to the effects of amniotic membrane transplantation on the ocular surface together with the problematic and unresolved issues. Thus, it is our sincere belief that further studies should be carried out along these lines.Item Dorzolamid-timolol ve brinzolamid-timolol kombinasyonlarının karşılaştırılması: yan etki profili ve hastaların tercihi(Uludağ Üniversitesi, 2014-12-02) Baykara, Mehmet; Poroy, Ceren; Bydak, Berna Akova; Asadova, Vusala; Can, Başak; Çiçek, Serhat; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.Çalışmanın amacı, glokom nedeniyle dorzolamid-timolol ya da brinzolamid-timolol fiks kombinasyonundan birini kullanmakta iken herhangi bir sebeple diğer kombinasyona geçilen hastalarda kombinasyonları yan etkiler açısından karşılaştırmak ve hastaların damla tercihini ve tedaviye uyumunu değerlendirmektir. Uludağ Üniversitesi Göz Hastalıkları Anabilim Dalı glokom polikliniğinde takip edilen ve dorzolamidtimolol ya da brinzolamid-timolol kombinasyonundan birini kullanırken diğerine geçilen 30 hastaya yan etkilerin ve tercih edilen damlanın sorgulandığı bir anket uygulanmıştır. Yaşları 14-81 arasında değişen 9 erkek, 21 kadın toplam 30 hastaya anket uygulanmıştır. Otuz hastanın % 66,7’ si dorzolamid-timolol kullanımı sonrasında batma, % 46,6’sı ise kızarıklık tariflemiştir. Bu durum brinzolamid-timolol kullanımı sonrasına oranla daha sıktır ve istatistiksel olarak anlamlıdır. (p değerleri sırasıyla 0,002 ve 0,012) Bulanık görme ise brinzolamid-timolol sonrası daha sık görülmekle birlikte (% 43,3) istatistiksel olarak anlamlı değildir.(p= 0,426) Hastalar genel izlenimleri ve tedaviye uyumları açısından sorgulandığında 30 hastanın 12’si (% 40) dorzolamid-timolol, 15’i (% 50) brinzolamid-timolol kombinasyonunu tercih etmiştir. Üç hasta (% 10) damlalar arasında fark olmadığını belirtmiştir. Bizim çalışmamızda brinzolamid-timolol kombinasyonu kullanımında daha az batma, kızarıklık ve daha fazla bulanık görme şikayeti görülmüştür. Her iki damla da etkinlik açısından kabul edilebilir tedavi seçenekleri olmakla beraber hastalar tercihlerini farklı yan etkilerden hangisini daha tolere edilebilir bulduğuna göre yapmaktadır.Item Early results of selective laser trabeculoplasty in patients resistant to deep sclerectomy(Sage Publications, 2014-05) Baykara, Mehmet; Amuk Hamidi, Nagihan; Akova, Berna Budak; Sabur, Huri; Poroy, Ceren; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; 0000-0003-0995-5260; ABI-7051-2020; ABE-3033-2020; AAI-8604-2020; 7004578592; 56140824200; 55370489800; 55633463900; 56142133900Purpose: In this study, we aimed to determine the early results of selective laser trabeculoplasty to trabeculo-Descemet membrane in patients resistant to deep sclerectomy (DS) surgery. Methods: Twelve eyes of 12 patients that had undergone DS for primary open-angle glaucoma were enrolled. Preoperative and postoperative intraocular pressures (IOP) were measured by Goldmann applanation tonometer. Time to failure after DS was noted. Failure is described as IOP higher than 20 mm Hg. All patients underwent selective laser trabeculoplasty (SLT) after failure. Eight to 10 applications of SLT were applied over the trabeculo-Descemet membrane. Laser was applied to the surgical site only. The IOPs before SLT, at postoperative first week, first month, and third month were measured. Results: Mean follow-up time was 23.5 +/- 9.5 months, Mean preoperative 10P was 34.2 +/- 6.7 mm Hg; mean postoperative 10P at first week was 12.7 +/- 3.2 mm Hg. Mean time to failure after DS procedure was 21.6 +/- 7.6 months. Mean 10P was 20.6 +/- 1.9 mm Hg just before SLT procedure. Mean 10P measurements after SLT at first week, first month, and third month were 10.5 +/- 2.2 mm Hg, 10.5 +/- 1.9 mm Hg, and 10.9 +/- 2.1 mm Hg, respectively. Conclusions: Selective laser trabeculoplasty after DS is an effective and noninvasive procedure that can be done on an outpatient basis. Our results suggest that SLT applied to the surgical site is an effective intervention in the short term but long-term results are required to assess the efficacy.Item The effect of anterior chamber maintainer on anterior chamber contamination(Sage Publications, 2003) Baykara, Mehmet; Özakın, Cüneyt; Doğru, Murat; Ertürk, Haluk; Heper, Yasemin; Özçetin, Hikmet; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; ABI-7051-2020; AAH-6506-2021; 23093006700; 57200678942; 7006540932; 7003716972; 56191003300; 6603402155PURPOSE. To evaluate the effect of anterior chamber continuous infusion maintainer system on the contamination of anterior chamber in phacoemulsification surgery. METHODS. Clear corneal phacoemulsification surgery was performed in 132 eyes of 132 randomly selected patients with cataract who were divided into two groups of 66 eyes according to the use of an anterior chamber maintainer (ACM) system. The fluid specimens were taken from anterior chamber in the beginning and at the end of the surgery. They were transferred under anaerobic conditions and investigated by culturing onto blood agar and thiogluconate broth media. Differences between the two groups with respect to contamination of the specimens were investigated. RESULTS. The mean age of the group undergoing surgery without a maintainer system (Group A) was 63 +/- 10 years (min = 41, max = 80) versus 59 +/- 10 years (min = 33, max = 80) in the other group (Group B) in which the maintainer was used during surgery. In the postoperative specimen, Micrococcus species were isolated from one eye (1.5%) in Group A and S. pyogenes in one eye (1.5%) from Group B. Mean follow-up interval was 12 +/- 6 (min = 4, max 28) months. CONCLUSIONS. The use of ACM system in clear corneal phacoemulsification surgery carries no additional risks as far as contamination is concerned.Item The effect of dexamethasone implant (Ozurdex (R)) on anterior chamber parameters in patients with retinal vein occlusion(Assoc Research Vision Ophthalmology, 2016-09) Yılmaz, Sami; Budak, Berna Akova; Kıvanç, Sertaç Argun; Kaderli, Berkant; Yalçınbayır, Özgür; Baykara, Mehmet; Yücel, Ahmet Ali; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; 0000-0003-0995-5260; ABE-3033-2020; ABI-7051-2020; AAH-6518-2021; AAH-6625-2021Item Effect of oral gabapentin on the intraocular pressure and haemodynamic responses induced by tracheal intubation(Wiley, 2008-09) Kaya, Fatma Nur; Yavaşçaoǧlu, Belgin; Baykara, Mehmet; Altun, Gülbin Töre; Gülhan, Nevra; Ata, Filiz; Uludağ Üniversitesi/Tıp Fakültesi/Anesteziyoloji ve Reanimasyon Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; AAI-7914-2021; AAI-8213-2021; AAG-9356-2021; 7003619647; 6602742300; 23093006700; 57224710693; 6504394933; 35168461500Background: Laryngoscopy and tracheal intubation may cause undesirable increases in blood pressure, heart rate (HR) and intraocular pressure (IOP). Gabapentin has been used effectively to attenuate the pressor response to laryngoscopy and tracheal intubation. We investigated whether the pre-treatment with gabapentin attenuates the IOP in addition to a haemodynamic response to tracheal intubation. Methods: Sixty ASA I-II patients were randomly allocated into two groups who received either gabapentin (800 mg) or placebo 2 h before surgery. IOP, mean arterial pressure (MAP) and HR were measured before and after the induction of anaesthesia as well as at 0, 1, 3, 5, 10 and 15 min following intubation. Results: IOP and MAP increased from baseline immediately after intubation in the placebo group (P = 0.001 and 0.002, respectively). When compared with the placebo group, IOP values of the gabapentin group were significantly lower for the first 15 min after tracheal intubation (P = 0.002 at 0 min, P = 0.006 at 1 min, P < 0.001 at 3 min, P < 0.001 at 5 min, P < 0.001 at 10 min and P = 0.003 at 15 min) while MAP was lower in the first 10 min (P = 0.001 at 0 min, P = 0.002 at 1 min, P < 0.001 at 3 min, P < 0.001 at 5 min and P = 0.028 at 10 min). These results showed that gabapentin effectively suppresses the increase in IOP secondary to endotracheal intubation and attenuates the increases in MAP. Conclusion: It is suggested that gabapentin is a useful adjuvant in order to prevent an increase in the IOP in response to laryngoscopy and tracheal intubation.Publication Evaluation of intraocular pressure change and anterior segment parameters after intravitreal bevacizumab injection - cannula size matters(Wolters Kluwer Medknow Publications, 2020-10-01) Hamidi, Nagihan A.; Güneş, Irfan B.; Baykara, Mehmet; Baykara, Mehmet; BAYKARA, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/OftalmolojiAnabilim Dalı.; ABI-7051-2020PURPOSE: To determine the changes in intraocular pressure (IOP) and anterior chamber parameters following intravitreal bevacizumab injection with different sizes of cannulas. METHODS: This clinical trial was conducted with 70 eyes of 70 patients who received an intravitreal injection of bevacizumab with 26 G (Group 1) or 30 G (Group 2) needle. Preinjection and postinjection 30th-min IOP and pentacam measurements were obtained. Anterior chamber depth (ACD), anterior chamber volume (ACV), central corneal thickness (CCT), corneal volume (CV), and iridocorneal angle (ICA) measurements were evaluated in pentacam. RESULTS: Preinjection mean IOP values in Group 1 and 2 were 14.7 +/- 3.29 mm Hg and 15.1 +/- 2.87 mm Hg, respectively. Postinjection mean IOP in Group 1 was 16.8 +/- 6.24 mm Hg and in Group 2 was 20.3 +/- 3.66 mm Hg. Postinjection mean IOP values were significantly higher than preinjection values in both groups (Group 1 P < 0.005 and Group 2 P < 0.001). IOP change was significantly higher in Group 2 after injection (P < 0.05). In both groups, the change in IOP found to be more significant in phakic eyes than pseudophakic eyes (Group 1 P < 0.001, Group 2 P < 0.001). CCT and CV were significantly higher in both groups 30 min after the injection than preinjection (Group 1 and Group 2; P < 0.01). In Group 2 ACD, ACV and ICA values were significantly lower than preinjection values (P < 0.05). CONCLUSION: Needle bore size is an important parameter that influences anterior segment parameters and IOP change in the intravitreal injection. IOP rise and anterior segment changes are more prominent with a thinner cannula.Publication Evaluation of the cataract surgery 2018 survey in terms of achieving refractive cataract surgery targets(Turkish Ophthalmological, 2021-01-01) Can, Izzet; Takmaz, Tamer; Ozdamar, Akif; Kamis, Umit; Akova, Yonca Aydin; Arslan, Osman Sevki; Devranoglu, Kazim; Gunenc, Uzeyir; Mutlu, Fatih Mehmet; Ozcan, Altan Atakan; Tasindi, Emrullah; Baykara, Mehmet; BAYKARA, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Oftalmoloji Anabilim Dalı.; 0000-0001-9494-8756; 0000-0001-6359-4799; 0000-0002-5555-1649; 0000-0003-0504-0370; 0000-0002-7796-6511; AAT-6236-2020; F-1103-2018; ABI-7051-2020Objectives: The aim of this study was to show at what rate the technological equipment used in cataract surgery by Turkish ophthalmologists and their knowledge are reflected in practice and how up to date they are.Materials and Methods: A questionnaire conducted using SurveyMonkey was used to evaluate the answers to 17 questions from 823 members of the Turkish Ophthalmological Association. Results were evaluated in subgroups according to the participants' age, occupational status, institutions, and whether they conducted relevant academic activities, and the data were compared as inadequate, standard, and contemporary approaches according to the determined criteria.Results: Optical biometry devices were used at rates of 77.7% and 67.3% for intraocular lens (IOL) power calculations and keratometric measurements in preparation for cataract surgery, respectively. For IOL power calculation, third-generation formulas, especially the SRK-T, were used most commonly (46.2%), followed by second-generation formulas (21.9%), and fourth/fifth-generation formulas and multiple evaluations for different axial lengths (31.9%). The most common incision size was 2.8 mm (51.6%), while the percentage of 2.2 mm and shorter incisions considered to be neutral in terms of surgically induced astigmatism was 18.8%. When selecting incision location, approaches to reduce corneal astigmatism were reported by 28.9%, neutral approaches by 26.2%, and insensitive approaches by 44.9%. Additionally, 55.6% of participants never implanted toric IOLs and 50.7% did not use presbyopia-correcting IOLs. The proportion of surgeons who have experience with femtosecond laser-assisted cataract surgery was 10.3% and the rate of intracameral antibiotic injection at the end of the operation was 89.4%.Conclusion: It was seen that Turkish cataract surgeons were able to use high technology for surgical preparation and surgery at high rates, but this was not reflected in practice at same rate in terms of achieving contemporary standards of refractive cataract surgery.Item Farklı çaplardaki enjeksiyon iğneleri ile yapılan göz içi (İntravitreal) uygulamalar sonrası göz içi basınç ve ön segment parametrelerinin değerlendirilmesi(Uludağ Üniversitesi, 2014) Hamidi, Nagihan Amuk; Baykara, Mehmet; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.Amaç: İntravitreal bevacizumab yapılan hastalarda kullanılan kanül çaplarının ön kamara parametreleri ve göz içi basınç değerleri üzerine etkisinin karşılaştırmalı olarak değerlendirilmesi. Gereç ve Yöntem: İntravitreal bevacizumab enjeksiyonu yapılan 70 hastanın 70 gözü çalışmaya dahil edildi. Enjeksiyon yapılan gözler kullanılan kanül çaplarına göre iki gruba ayrıldı (26 G ve 30 G). Gruplar işlem öncesi ve sonrası 30. dakika göz içi basınçları ve Pentacam ölçümlerindeki değişime göre değerlendirildi. Pentacam ölçümlerinde ön kamara derinliği, ön kamara hacmi, kornea kalınlığı, kornea hacmi, iridokorneal açı ve kornea eğim değerleri incelendi. Bulgular: Her iki grupta göz içi basıncın işlem öncesi değerlere göre 30. dakikada anlamlı derecede yüksek olduğu ve daha ince kanül kullanılan grupta göz içi basınç değişiminin kalın kanül kullanılan gruba göre daha fazla olduğu görüldü. İşlem sonrası 30. dakikada ön kamara derinliği, ön kamara hacmindeki azalmanın ince kanül kullanılan grupta anlamlı olduğu izlendi. Kornea hacmi ve kornea kalınlığı her iki grupta da işlem sonrası ölçümde anlamlı derecede yüksek izlendi. Kornea eğrilik değerlerinde her iki grupta işlem sonrası dönemde anlamlı değişim izlenmedi. Psödofakik hastalarda ön kamara parametrelerindeki değişim fakik hastalara göre daha fazla idi. Sonuç: 30. dakikada daha ince kanül kullanılan hastalarda daha kalın kanül kullanılan hastalara göre ön kamara parametrelerinin normalleşmediği ve göz içi basınç yüksekliğinin yine diğer gruba göre daha fazla olduğu gözlendi. Bu durum ince kanül çapının, 30. dakikada artmış göz içi basıncı ve ön kamara parametrelerindeki değişim için bir risk faktörü olduğunu desteklemektedir.Item Free iris cyst in the anterior chamber(Slack, 2004) Sahin, Sunay; Baykara, Mehmet; Ertürk, Haluk; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; 7004578592; 7003716972A 50-year-old man had a free iris cyst in the anterior chamber that was treated by puncturing using an Nd:YAG laser. Following laser treatment, the cyst wall settled in the anterior chamber angle and no complications were encountered during 4 months of follow-up.Item Göz polikliniğine başvuran ve ilaç reçetesi verilmiş hastaların tedavi uyumlarının incelenmesi(Uludağ Üniversitesi, 2013-11-14) Gelişken, Öner; Budak, Berna Akova; Toka, Fatih; Baykara, Mehmet; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.İlaç uyumu tedavinin en önemli basamaklarındandır. Biz bu çalışmada göz polikliniğine başvuran hastalarda ilaç uyumunu ve uyumu etkileyebilecek faktörleri değerlendirmeyi amaçladık. Nisan 2010-Temmuz 2010 tarihleri arasında çalışmaya dahil edilen 80 hastaya demografik ve sosyoekonomik özelliklerini ortaya koymak için anket uygulandı. Hastaların demografik ve sosyoekonmik özelliklerinin ilaç uyumuna etkisi belirlenmeye çalışıldı. Hastalarımızın 42'si kadın 38'i erkekti. Hastaların ilaç uyumu %84 olarak saptandı. İlaç uyumunu bozabilecek birçok faktör vardır. Hastalara gerekli bilgi verilirse, ilaçların yan etkileri anlatılıp önlemler alınırsa ilaç uyumu artabilir.
