Purpose: To evaluate the effect of rheumatoid arthritis (RA) on choroid, retinal nerve fiber layer (RNFL), and foveal thickness using spectral domain optical coherence tomography (OCT).
Methods: Fifty patients with RA and forty-one healthy volunteers were enrolled in this study. The subfoveal, perifoveal choroidal, RNFL, and foveal thicknesses were measured by spectral domain OCT.
Results: The mean subfoveal, nasal, and temporal choroidal thicknesses in RA individuals were significantly higher than those in the control group (p ˂ 0.05). However, there was no significant difference between the RA and healthy group regarding RNFL and foveal thickness (p ˃ 0.05). A significant correlation was found between rheumatoid factor (RF) and the subfoveal temporal choroidal thickness.
Conclusion: Choroidal thickness in RA patients was higher than that in healthy participants. Choroidal thickening showed a positive correlation with RF, which may be an indicator for systemic vasculitis.

: Amblyopia is a condition where children undergo unilateral or bilateral vision loss due to a variety of disorders that impact the visual pathway. The assessment of retinal nerve fiber layer (RNFL) thickness in amblyopia has made optical coherence tomography (OCT) a useful technique for studying the pathophysiology of this condition. This study was conducted to assess OCT results for various forms of amblyopia, including macular thickness and peripapillary RNFL thickness.

: The aim of our study was to evaluate the retinal nerve fiber layer (RNFL) and macular and choroidal thicknesses in women with different phenotypes of polycystic ovary syndrome (PCOS), and compare these measurements with those of healthy women of reproductive age. : This prospective case-control study included 120 eyes of 120 women with PCOS, with each of the four distinct phenotypes comprising 30 eyes of 30 women. Additionally, 30 eyes from 30 healthy women were included in the control group.

Purpose: To evaluate the impact of Implantable Collamer Lens (ICL) implantation on anterior chamber angle parameters and posterior segment structures in highly myopic eyes and explore potential correlations between these changes. The study aimed to assess alterations in superficial and deep vessel density (SVD, DVD), foveal avascular zone (FAZ) area, and retinal nerve fiber layer (RNFL) thickness to clarify the safety profile of ICL implantation.
Methods: Prospective observational study, included 36 highly myopic eyes undergoing ICL implantation in surgery group and 23 non-surgical control eyes in non-surgery group.

The impact of various neurodegenerative diseases on the retina has been investigated in recent years using optical coherence tomography (OCT). Epilepsy, classified as a neurodegenerative disorder, has been indicated to affect the structural integrity of the retina. Moreover, there is ongoing debate regarding the relative contribution of the disease pathogenesis and the consumption of anti-epileptic drugs (AEDs) to these retinal changes.

Background: Previous investigations on optical coherence tomography (OCT) in multiple sclerosis (MS) focused on generalizable macular and peri-papillary regions without considering the anatomic variations of the retinal layer thickness.
Objective: This study aimed to assess the utility of parafoveal retinal layer thickness measured by OCT, underscoring its relationships with clinical outcomes in MS.
Methods: In this cross-sectional study, 214 people with MS (pwMS) and 57 age- and sex-matched healthy controls (HCs) were enrolled.
