Purpose: This study was conducted to evaluate visual function and changes in the central macular thickness of patients with unresponsive neovascular age-related macular degeneration who were switched from ranibizumab (Lucentis®) to aflibercept (Eylea®) treatment at 30 months.

Methods: This retrospective study examined patients with neovascular age-related macular degeneration who were switched to aflibercept after ≥6 previous intravitreal ranibizumab injections at 4- to 8-week intervals. All patients were switched to intravitreal aflibercept (2.

Objectives: This study was an analysis of the retinal layer thickness in multiple sclerosis (MS) patients using spectral-domain optical coherence tomography (SD-OCT).

Methods: A total of 42 patients diagnosed in the neurology clinic with MS according to the McDonald Criteria and 21 healthy individuals were included in the study and 4 groups were created. The first group comprised 21 eyes of 21 MS patients without eye involvement, the second group was made up of 21 eyes of 21 MS patients with a history of optic neuritis, the third group included the other eye of patients in the second group without a history of optic neuritis, and the fourth group was a control group of 21 eyes of 21 healthy individuals.

This report describes the therapeutic effects and outcomes of an accidental injection of an intralenticular sustained-release dexamethasone implant (Ozurdex®) in three patients with diabetic macular edema. All three patients underwent accidental injections of sustained-release intravitreal dexamethasone implants into the crystalline lens by the same surgeon. After the accidental injection of Ozurdex® into the crystalline lens, a remarkable reduction in the macular edema and an improvement in visual acuity were observed, suggesting that a positive outcome can be achieved without immediate surgery.

Purpose: This research is aimed at determination of total oxidant status, total antioxidant status, serum thiol-disulfide, catalase, albumin, ischemia-modified albumin, and ceruloplasmin in patients suffering from retinitis pigmentosa and drawing a comparison with these parameters determined from healthy controls.

Methods: The study involved 35 patients of retinitis pigmentosa and 33 controls who were healthy individuals of comparable gender and age. Native thiol, total thiol, disulfide concentration, disulfide/native thiol, disulfide/total thiol, native thiol/total thiol ratios, total oxidant status, total antioxidant status, catalase, ceruloplasmin, albumin, and ischemia-modified albumin were determined from peripheral blood samples and comparison was drawn between the measurements of retinitis pigmentosa and controls.

Background & Objectives: Cataract is one of the leading causes of blindness in the world. The aim of the present study was to investigate anticataractogenic effect of betaine in chick embryo hydrocortisone (HC)-induced cataract model.

Methods: The study included 60 fertilized eggs divided into six groups each having 10 eggs: one group treated with only HC (HC group); three treated with both HC and different doses of betaine (HC/B 1.

Background: This study aimed to compare pain scores of patients during intravitreal aflibercept, ranibizumab or dexamethasone implant injection procedures.

Methods: This study included 162 eyes of 162 patients, who received intravitreal ranibizumab, aflibercept or dexamethasone implant injections at our clinic. Following the injection, patients were asked to rate their pain from 0 (no pain) to 10 (worst pain) using a visual analogue pain score survey (VAS).

Background/aim: Age-related cataract is the most important visual impairment all over the world. Epigenetic modifications, especially overexpression of histone deacetylases, have become the focus of interest for cataract development in recent years. Sirtuin 1 (SIRT1), a class II histone deacetylase and a member of the sirtuin family, is one of the best-characterized histone deacetylases and has a pivotal role in age-related diseases.

Purpose: The aim of this study was to present an experimental optical coherence tomography (OCT)-guided anterior segment (AS) imaging chick embryo model. Through this model, we aimed to reveal similarities and differences between human cornea, AS tissues, and chick embryo tissues by quantitative image analysis.

Methods: Ex vivo, the chick embryos' globes were determined by detailed AS camera of spectral-domain (SD)-OCT in 10 fertilized specific pathogen-free eggs on the 20 day.

Aim: To reveal the changes of corneal endothelial characteristics with aging among Caucasian population.

Methods: Non-contact specular microscopy was performed in 564 eyes of 282 healthy Caucasian Turkish patients. Endothelial cell density (MCD), mean cell area (MCA), coefficient of variation (CV) in cell size, percentage of hexagonal cells, and central corneal thickness (CCT) were measured.

Cutaneous leishmaniasis is a parasitic disease caused by the Leishmania species, transmitted by the bite of an infected sandfly. The typical cutaneous lesion is a painless ulcer with a raised, indurated margin and often covered with an adherent crust. The lesions are mostly located on exposed sites such as the face and the extremities.
