Aim: To investigate choroidal thickness in healthy Turkish subjects.
Materials And Methods: Refraction, axial length (AXL) measurement, anterior chamber, and fundus examinations were performed. Eyes that had any retinal or choroidal pathology were excluded from the study. Enhanced-depth imaging optical coherence tomography was used to evaluate choroidal thickness.
Results: 139 eyes from 70 subjects were investigated. The mean age, AXL, spherical equivalent refractive error (SE), and subfoveal choroidal thickness (SCT) were 34.7 +/- 12.7 years, 23.31 +/- 0.91 mm, -0.15 +/- 1.64 diopters (D), and 326 +/- 60 microm, respectively. A negative correlation was found between SCT and AXL (P = 0.043). The mean age, SE, AXL, and SCT were 31.7 +/- 9.3 and 34.6 +/- 14.3 years, -0.27 +/- 1.45 and 0.02 +/- 1.89 D, 23.52 +/- 0.94 and 23.02 +/- 0.75 mm, and 324 +/- 69 and 329 +/- 40 mirom in male and female subjects, respectively (P = 0.14, P = 0.31, P = 0.001, and P = 0.58, respectively). Regression analysis showed that SCT decreased by 0.93 microm for each year of age.
Conclusion: In healthy Turkish subjects, SCT decreased by 0.93 pm for each year of age and was thicker in men when the results were adjusted according to AXL measurements.

: The aim of this study is to investigate the effect on choroidal parameters of drug withdrawal in patients taking α1 adrenergic receptor antagonist (ARA) inhibitors. : In total, 32 eyes of 32 patients under alpha-lytic therapy, and 32 eyes of 32 control subjects, both scheduled for cataract surgery in the fellow eye, were included. EDI-OCT was performed in all patients and subfoveal choroidal thickness (SFCT), luminal choroidal area (LCA), stromal choroidal area (SCA), total choroidal area (TCA), and choroidal vascularity index (CVI) during the preoperative visit were compared with data approximately 1 month after alpha-lytic withdrawal.

Background/objectives: To evaluate the impact of intravitreal bevacizumab (IVB) therapy on anatomical and visual outcomes in patients with macular neovascularization (MNV) secondary to chronic central serous chorioretinopathy (cCSC).
Methods: This retrospective observational study reviewed the medical records of treatment-naïve patients diagnosed with cCSC complicated by MNV and treated with IVB injections over a 5-year period. The presence of MNV was confirmed using optical coherence tomography angiography (OCTA).
Age-Related Choroidal Involution Is Associated with the Senescence of Endothelial Progenitor Cells in the Choroid.

Choroidal involution is a common feature of age-related ischemic retinopathies such as age-related macular degeneration (AMD). It is now well recognized that endothelial progenitor cells (EPCs) are essential to endothelial repair processes and in maintaining vascular integrity. However, the contribution of EPCs and the role of senescence in age-related choroidal vascular degeneration remain to be investigated.

Background: Ultra-wide-field optical coherence tomography (UWF-OCT) devices have recently been introduced to clinical practice. The goal of this study was to compare choroidal and retinal thickness (CT and RT) in age-related macular degeneration (AMD) with a healthy control group using UWF-OCT Xephilio S1. Additionally, we sought to determine the relationship between the RT and CT of patients with AMD, measured in different sectors, and their visual acuity.

: The objectives of this study were to evaluate the structural and functional outcomes after the loading phase with brolucizumab in switched patients with diabetic macular edema (DME) and to identify potential predictive biomarkers of treatment response. : A total of 28 eyes with DME, switched to brolucizumab, were retrospectively reviewed. Main outcomes during the follow-up period, up to 6 weeks after the fifth injection, included changes in best-corrected visual acuity (BCVA), central subfield thickness (CST), macular volume, subfoveal choroidal thickness, intraretinal and subretinal fluid (IRF and SRF), cyst dimension including maximal horizontal cyst diameter (MHCD), maximal vertical cyst diameter (MVCD), width-to-height ratio (WHR), foveal avascular zone (FAZ) dimension, and vessel density (VD).
