Purpose: To investigate the effect of the most commonly performed strabismus surgery procedures on the blood-aqueous barrier using laser flare photometry (LFP).

Methods: Patients who underwent unilateral or bilateral strabismus surgery between January 2020 and May 2021 were included. Eyes were grouped according to the number of rectus muscles operated: one rectus muscle procedure (recession) with or without inferior oblique anterization (IOA), ipsilateral two rectus muscle procedure (recession and resection) with or without IOA, and unoperated fellow eyes of patients undergoing unilateral surgery.

Backgrounds: To evaluate the optical coherence tomography (OCT) biomarkers of patients with central serous chorioretinopathy (CSC) according to the presence or absence of direct anatomical relation to intervortex vein anastomosis (IVA) on indocyanine green angiography.

Methods: We reviewed the records of 39 patients with chronic CSC. Patients were categorized in 2 groups: presence of IVA(Group A) or absence of IVA(Group B) in the macular region.

Objectives: The aims of this study were to describe the clinical presentation and treatment modalities of acute retinal necrosis (ARN) and to evaluate complications and clinical outcomes according to the extent of retinal involvement at initial presentation.

Materials And Methods: The medical records of 52 patients diagnosed with ARN were reviewed and 48 were included in the study. Patients were categorized into two groups according to the extent of retinitis at presentation: retinal involvement of 1-2 quadrants (Group A) or 3-4 quadrants (Group B).

Objectives: To evaluate the effect of upper eyelid surgery on ocular surface and corneal topography.

Materials And Methods: Patients who underwent upper eyelid blepharoplasty and/or blepharoptosis repair were evaluated prospectively. Tear film break-up time (TBUT), Schirmer tests, corneal staining pattern, Ocular Surface Disease Index questionnaire, corneal topography, and autorefractor parameters were measured preoperatively and at 1 day, 1 week, 1 month, 3 months, and 6 months postoperatively.

Purpose: This study aimed to investigate whether femtosecond laser-assisted LASIK (FS-LASIK) surgery causes inflammation in the anterior chamber and to analyze its effect on endothelial cells.

Methods: This prospective, longitudinal study included left eyes of 30 patients (19 females) who had undergone FS-LASIK surgery due to myopia and myopic astigmatism. Endothelial cell density (ECD) and morphological measurements were performed using a specular microscopy, and laser flare photometry was used to measure the anterior chamber flare values on the day of surgery.

Introduction: Retinal nerve fiber layer thickness has been used for monitoring of disease activity in patients with multiple sclerosis (MS). Macular ganglion cell complex (GCC) layer of retina also can be measured by OCT and has been suggested as a potential biomarker in MS. In this study we investigated the macular GCC and its role as a potential biomarker in patients with Multiple Sclerosis (MS).

Purpose: To report the results of interferon (IFN) α-2a treatment in patients with cystoid macular edema (CME) secondary to acute retinal necrosis (ARN).

Methods: We reviewed the records of seven patients (eight eyes) who received IFNα-2a for post-ARN CME. The initial dose of IFNα-2a was 3 MIU/day and it could be tapered down to 3 MIU twice a week.
