Analysis of retinal sublayers in patients with systemic COVID-19 illness with varying degrees of severity.

COVID-19 infection has been linked to ocular involvement, particularly retinal microvascular changes. Additionally, prolonged hypoxemia may affect retinal sublayers located within the retinal watershed zone. The aim of this study was to evaluate retinal and optic nerve OCT parameters in patients with COVID-19 illness of varying severity and compare them with controls.

Establishing normal interocular symmetry range for macular optical coherence tomography parameters in healthy children.

Objective: The study aimed to evaluate the interocular symmetry of macular sublayer thickness among healthy children aged 6-12 years.

Methods: The Shiraz Pediatric Eye Study included 500 randomly selected children who underwent SD-OCT of the macula and optical biometry using the IOLMaster-500. Exclusion criteria involved ocular abnormalities or axial lengths outside the 21.

Evaluation of changes in thickness of macular sublayers in patients using Hydroxychloroquine: a cross sectional case-control study and literature review.

Purpose: To assess changes in the thickness of macular sublayers in individuals taking hydroxychloroquine (HCQ) without any evident toxicity and to review the relevant literature.

Methods: This prospective case-control study examined 47 adults on HCQ without evident toxicity on spectral-domain optical coherence tomography (SD-OCT) and visual field tests, as well as 25 healthy controls. Macular thickness in different sublayers was measured using SD-OCT.

A systematic review of the potential treatment effects of topical epidermal growth factor for ocular surface disorders.

Purpose: This systematic review, evaluated the role of epidermal growth factor (EGF) in corneal wound healing and the pathogenesis of ocular surface disorders (OSDs).

Methods: The clinical and experimental application of topical EGF therapy for OSDs was reviewed. This systematic research assessed articles published on PubMed/MEDLINE from 2000 to 2023 and summarized and discussed the findings of 38 experimental and 10 clinical studies.

Comparison of ocular biometric measurements and intraocular lens power calculation using different methods in eyes with implantable collamer lenses.

This prospective cohort study included 80 healthy candidates for Implantable Collamer Lens (ICL) implantation who underwent biometric assessments with Scheimpflug imaging (the Pentacam-AXL) and swept-source optical coherence tomography (SS-OCT; the IOLMaster-700), both before and 3 months after surgery. The main outcome measures were mean keratometry, anterior chamber depth, axial length, and various intraocular lens (IOL) calculation formulas (Haigis, SRK/T, Hoffer Q, Holladay 1, Barrett Universal 2, and Olsen). The interchangeability of the devices was assessed by generating 95% limits of agreement (95% LoA) and associated Bland-Altman plots.
