The Corneal Epithelial Thickness Profile in a Healthy Saudi Population.

Introduction: Epithelial mapping appears to be a valuable technique for a corneal and refractive surgeon, useful for distinguishing corneas with the true presence of corneal ectasia from those that are suspicious. Interpreting the epithelial thickness map data requires an understanding of corneal epithelial thickness (CET) normal values and variable patterns. Unlike corneal thickness, epithelial thickness assessment with anterior segment optical coherence tomography (AS-OCT) seems to be influenced by gender and age.

Effect of Ablation Depth on the Endothelial Status of Eyes of Myopic Patients Undergoing Transepithelial Photorefractive Keratectomy: A Retrospective Study in Saudi Arabia.

Purpose: The aim of this study was to correlate ablation depth on corneal endothelial cell (EC) indices following transepithelial photorefractive keratectomy (TPRK) in Saudi myopic patients.

Methods: This was a retrospective cohort study of myopic eyes treated with TPRK. The changes in EC density and other indices were noted one week (W1) and 12 weeks (W12) after TPRK, which was the primary outcome.

Effect of mitomycin C on the corneal endothelial cells of Saudi patients with myopia after transepithelial photorefractive keratectomy: a two-armed cohort study.

Aim: To study the effect of mitomycin C (MMC) applied during transepithelial photorefractive keratectomy (TPRK) on the corneal endothelium one week (W1) and three months (M3) after surgery and its determinants.

Methods: In this two-armed cohort study conducted in 2022, eyes treated with MMC during TPRK (group 1) were compared with eyes not treated with MMC (group 2). The corneal endothelial cell (EC) count, EC density (ECD; cells/mm), average (µm), standard deviation (µm), coefficient of variation (CV%), EC, EC, and EC percentage of hexagonality were estimated at W1 and M3.

Accommodative insufficiency in post-COVID-19 case with refractive error.

The aim of the case report is to present refractive error with accommodative insufficiency as a possible postinfectious manifestation of coronavirus disease-2019 (COVID-19). Three weeks after the COVID-19 infection, a 22-year-old subject presented with blurring of distance and near vision with a frontal headache after prolonged near work. The patient was not using any refractive correction before the COVID-19 infection.

Knowledge and practices of fundoscopy among general practitioners in Qassim Province, Saudi Arabia, for the management of diabetic retinopathy and diabetic macular edema: A cross-sectional study.

Objectives: Blindness is one of the most widespread final pathways of diabetic retinopathy and its associated diabetic macular edema. The general practitioners are the first to encounter these diabetic patients. Fundoscopy is now considered as an ideal way for the diagnosis of patients with diabetic retinopathy.

Black Diaphragm Intraocular Lens Implantation in Patients with Aniridia.

Purpose: To review the management outcomes of black diaphragm intraocular (BDI) lens implantation in Arab patients with aniridia.

Methods: Patients with aniridia undergone BDI lens implantation at our institution between 2013 and 2014 were included. Uncorrected visual acuity (UCVA), manifest refraction, and best-corrected visual acuity (BCVA) were evaluated before and 6 months and yearly after BDI lens implant surgery until the last visit.

Pattern of refractive errors in Buraydah. How serious is the problem?

Objective: The incidence of refractive errors is on the rise globally. This study was done to assess the pattern and prevalence of various errors of refraction including myopia, hypermetropia, and astigmatism in Qassim region of Saudi Arabia.

Methods: This is a cross-sectional study conducted in Buraydah city during January 2015.

Prevalence Refractive Errors among Medical Students of Qassim University, Saudi Arabia: Cross-Sectional Descriptive Study.

Objective: To study the prevalence of various errors of refraction among the medical students studying at the college of medicine, Qassim University, Saudi Arabia.

Methods: This is a cross-sectional descriptive study conducted at Qassim University clinics over a period of two months. The study population comprised 162 male and female students from different academic years.

Removal of Retained Descemets Membrane Using Femtosecond Laser.

We present a unique method of retrocorneal membrane removal with a femtosecond laser (FSL). A 22-year-old male who had undergone penetrating keratoplasty had a retained retrocorneal membrane and a double anterior chamber postoperatively. The membrane was dissected completely with the FSL and the free-floating membrane was removed.

Cataract surgery under systemic infliximab therapy in patients with refractory uveitis associated with Behcet disease.

Background And Objectives: This study is to evaluate the outcome of cataract surgery in patients with refractory uveitis associated with Behçet disease (BD) treated with infliximab.

Design And Settings: A retrospective study in a university-based tertiary referral center in the period between July 2003 and November 2011.

Methods: This is a retrospective study of patients with refractory uveitis associated with BD who underwent phacoemulsification cataract surgery under systemic infliximab therapy between July 2003 and November 2011 at King Abdulaziz University Hospital, Riyadh, Saudi Arabia.
