    Purpose: Investigation of the efficacy of intravitreal dexamethasone implants (0.7 mg) in patients with Behcet disease (BD) who had cystoid macular edema (CME) despite immunomodulatory treatment. Materials and Methods: Twenty-seven eyes of 20 patients who had intravitreal dexamethasone implant injections and follow-up for more than 6 months were included in this study. Best corrected visual acuities (BCVA), intraocular pressures (IOP), and central macular thicknesses (CMT) were recorded. Systemic immunomodulatory treatment was noted. Injection-related complications and the need for recurrent injections were recorded. Results: Statistically significant anatomical and functional success was achieved with a single injection. BCVA increased from 0.85 +/- 0.72 to 0.45 +/- 0.52 logMAR, while the mean CMT decreased from 406 +/- 190 to 243 +/- 101 mu m at the sixth month. The peak of visual acuity gain was reached within the first 2 months and a substantial proportion of the patients gained 3 or more lines. There was no complication other than transient IOP elevation in 4 eyes and cataract surgery in 2 eyes. Conclusion: Adjuvant intravitreal dexamethasone implant injections offer promising results in cases of BD with CME. It is effective in preserving the macular anatomy and vision particularly in transition to biological agents.

    Evaluation of choroidal thickness in children with type 1 diabetes: The role of optical coherence tomography in diabetic retinopathy screening
    (Japanese Soc Pediatric Endocrinology, 2021-01-01) Ermerak, Basak Can; Yalcinbayir, Ozgur; YALÇINBAYIR, ÖZGÜR; Eren, Erdal; EREN, ERDAL; Erseven, Cansu; Sobu, Elif; Yucel, Ahmet Ali; YÜCEL, AHMET ALİ; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Oftalmoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Endokrinoloji Anabilim Dalı.; 0000-0002-7311-5277; 0000-0002-1684-1053; JAC-9459-2023; AAH-6226-2021; IYJ-9408-2023; GSN-9730-2022; AAH-6625-2021
    The present study aimed to evaluate choroidal changes and alternations within the structure of the retina prior to visible morphologic signs of diabetic retinopathy (DR) in pediatric type 1 diabetes (T1D) cases. Two hundred and six eyes of 103 pediatric patients with T1D without DR and 88 eyes of 44 healthy controls were enrolled. They underwent a comprehensive ophthalmic examination and optical coherence tomography evaluation. Choroidal thickness (ChT) measurements were performed manually on macular and peripapillary regions. There was no significant difference between the two groups in terms of age, intraocular pressure, and axial length (p > 0.05). ChT measurements of subfoveal, nasal, and temporal macula were slightly thinner in the diabetic group, and no statistical significance was found (p = 0.835, p = 0.305, and p = 0.054, respectively). Peripapillary ChT of eight sectors were also thinner in T1D; however, superonasal, nasal, inferonasal, and inferior sector values were significantly different (p = 0.010, p = 0.020, p = 0.019, and p = 0.018, respectively). In conclusion; this study demonstrated evidence of peripapillary choroidal thinning in pediatric diabetic patients without visible signs of retinopathy.

    Objective To investigate whether the Tei index, which is an indicator of global myocardial function and an independent predictor of cardiac death, is increased in patients with branch retinal vein occlusion (BRVO).Methods The Tei index was used to evaluate myocardial performance, in addition to conventional echocardiographic evaluation of myocardial structural and functional changes, in patients with BRVO, patients with hypertension and healthy controls.Results Out of 36 patients with BRVO (18 female, 18 male; 17 hypertensive, 19 normotensive), 29 patients with hypertension (15 female, 14 male) and 28 healthy controls (15 female, 13 male), there were no significant between-group differences in age and sex. The mitral A wave was higher and mitral E/A ratio, mitral E wave and ejection time were lower, in patients with BRVO than in healthy controls. Mean Tei index was significantly higher in the BRVO group than in patients with hypertension or healthy controls. Compared with healthy controls, the Tei index was significantly higher in hypertensive and normotensive patients with BRVO.Conclusion Myocardial performance is decreased in patients with BRVO, independent of whether or not they have hypertension.
