Background: The purpose of this study was to evaluate and compare the values of hexagonality of endothelial cells among type-2 diabetics and nondiabetics. It also aimed at finding the correlation of the hexagonality of endothelial cells with the duration of diabetes, random blood sugar level, and severity of diabetic retinopathy in type-2 diabetics.

Materials And Methods: A comparative cross-sectional study was conducted for 8 months from January to August 2022.

Prevalence of dry eye disease among IT students in Pakistan.

Int Ophthalmol

April 2024

School of Optometry and Vision Science, Level 3, Rupert Myers Building, Gate 14 UNSW, Barker Street, Kensington, Sydney, Australia.

Background: Dry eye disease (DED) is a common tear film disorder caused by decreased tear production or increased tear evaporation. The increased use of computers in the workplace has brought about the development of ocular health concerns, including dry eye disease. Therefore, this study was designed to determine the prevalence of DED associated with computer work and recommend preventing or reducing its development.

Is Pterygium Morphology Related to Loss of Corneal Endothelial Cells? A Cross-Sectional Study.

Clin Ophthalmol

March 2021

Pakistan Institute of Ophthalmology (PIO), Department of Cornea and Refractive Surgery, Al-Shifa Trust Eye Hospital, Rawalpindi, Pakistan.

Purpose: To determine the difference in mean corneal endothelial cell density (CECD) between the healthy and diseased eyes of the patients with unilateral pterygium with different morphology patterns by using a non-contact specular microscope (SP2000: Topcon Corporation, Japan) and to find out any relationship between severity of pterygium and daily sunlight exposure with the CECD loss.

Methods: A descriptive cross-sectional prospective study was carried out at Al-Shifa Trust Eye Hospital (ASTEH), Rawalpindi, Pakistan from 21st January 2019 to 22nd January 2020. Two hundred eyes (n= 100 patients) of age range18 -68 years with unilateral pterygium were selected.

LOXL1 (lysyl oxidase-like 1) has been identified as the major effect locus in pseudoexfoliation (PEX) syndrome, a fibrotic disorder of the extracellular matrix and frequent cause of chronic open-angle glaucoma. However, all known PEX-associated common variants show allele effect reversal in populations of different ancestry, casting doubt on their biological significance. Based on extensive LOXL1 deep sequencing, we report here the identification of a common non-coding sequence variant, rs7173049A>G, located downstream of LOXL1, consistently associated with a decrease in PEX risk (odds ratio, OR = 0.

Article Synopsis
  • Exfoliation syndrome (XFS) is a significant risk factor for secondary glaucoma, contributing to blindness globally, with known genetic variants in LOXL1 and CACNA1A linked to the condition.
  • Researchers conducted a study analyzing samples from multiple countries, discovering a rare protective allele at LOXL1 and refining its association, which had been previously inconsistent across different populations.
  • A genome-wide association study identified seven significant genetic loci related to XFS, providing new insights into its biological mechanisms and emphasizing the role of rare LOXL1 variants in the disease's development.

Article Synopsis
  • Primary angle closure glaucoma (PACG) is a key cause of blindness, prompting a large-scale study involving over 10,000 PACG patients and nearly 30,000 controls across multiple continents.
  • The study identified five new genetic loci associated with PACG risk, each with significant statistical results (e.g., EPDR1 with an odds ratio of 1.24 and a P-value of 5.94 × 10(-15)).
  • Additionally, three previously known genetic loci were confirmed, enhancing the understanding of the genetic factors underlying PACG.
