BackgroundVitiligo is a disease characterized by depigmented macules and patches that occur as a result of the loss of functional melanocytes from the affected skin through a mechanism which has not been elucidated yet. Destruction of pigment cells in vitiligo may not remain limited to the skin; the eyelashes, iris, ciliary body, choroid, retinal pigment epithelium and meninges may also be affected. This study aims to compare the choroidal thickness of patients with and without vitiligo using optical coherence tomography (OCT).MethodsSpectral-domain optical coherence tomography (SD-OCT) (Retina Scan Advanced RS-3000 NIDEK, Japan) instrument (with λ = 840 nm, 27,000 A-scans/second and 5 μm axial resolution) was used for the imaging. Statistical analysis was performed using SPSS 21.0 software package.ResultsIn all values except optic nevre area measurements, the choroidal thickness of all vitiligo patients was found out to be thinner compared to the control group.ConclusionsIn vitiligo, the choroidal thickness may be affected by the loss of melanocytes.

Introduction: Neuroimaging studies of patients with bipolar disorder (BD) have recently revealed neurodegenerative changes in the central nervous system. Optical coherence tomography (OCT) imaging of the retina, as an extension of brain, may be a biomarker in understanding the neurobiology of the disease. To assess OCT as a tool to detect neurodegeneration in BD we compared the retinal changes between patients with BD and healthy individuals. Methods: We performed complete ophthalmological examinations and took OCT images for 70 eyes of 70 patients with BD, and for age and sex-matched individual controls. We compared retinal nerve fiber layers (RNFLs) and total retinal (TR) thickness in the peripapillary areas; and ganglion cell complexes (GCCs) and TR thickness in the maculas between the groups. Results: The mean age of the patients was 40.41 ± 13.22 years and that of the controls 40.20 ± 13.03 years. The men/women ratios were 37/33 in both groups. BD

A 21-year-old woman developed simultaneous rhegmatogenous retinal detachment after laser in situ keratomileusis (LASIK) in both eyes. She underwent pars plana vitrectomy surgery combined with endolaser photocoagulation and silicone oil tamponade in the right eye. A week later, pneumatic retinopexy was done in the left eye. As the retinal tear did not seal, 360° scleral buckling surgery was performed and retina was attached. Bilateral simultaneous rhegmatogenous retinal detachment after LASIK for correction of myopia can be a serious complication. Patients should be informed about the possibility of this complication.

However, an American Society of Retina Specialists 2017 survey showed that ICG remains in use and that retinal specialists, particularly those in the United States, prefer it to other dyes for assisting with epiretinal membrane and/ or ILM peeling. This provides further evidence that toxicity of intravitreal ICG is still a relevant issue. In conclusion, this report demonstrates that ICGA cannot be taken for a certain period after ICGassisted ILM peeling in an eye with RD secondary to posterior scleritis. The atypical ICGA findings suggest that caution should be used to prevent unnecessary ICG diffusion within the eye (e.g., mixing ICG with viscoelastics 2).

Amaç: Sekonder göz içi lens (GİL) implantasyonu yapılan hastalarda, preoperatif oküler risk faktörlerini ve ikincil GİL cerrahisi endikasyonlarını belirlemek ve bu işlemin görsel sonuçlarını karşılaştırmak amacıyla yapılacaktır. Gereç ve Yöntemler:Kırıkkale Üniversitesi Tıp Fakültesi'nde, Ocak 2018 ve Şubat 2019 tarihleri arasında sekonder GİL implantasyonu yapılan ve postoperatif en az 3 ay takibi olan 19 hasta çalışmaya dâhil edildi. Ameliyat öncesinde hastaların sekonder GİL implantasyonu nedenleri; psödoeksfoliyasyon (PEKS), üveit gibi ek oküler patolojiler, travma, sistemik sendromlar, ameliyat öncesi ve sonrası düzeltilmiş en iyi görme keskinlikleri (DEGK), uygulanan cerrahi yöntem ve olası postoperatif komplikasyonlar ayrı ayrı not edildi.
