Screening Preadolescents for Keratoconus Risk Factors in a Low-Resource Setting.

Background: Diagnosis of keratoconus (KC) involves the identification of corneal signs, refraction, and corneal imaging. The prevalence of KC ranges between 0.4 per 100,000 and 4,790, depending on geographical location and ethnicity.

The Impact of Hyperopia on Academic Performance Among Children: A Systematic Review.

Purpose: To assess the impact of uncorrected hyperopia and hyperopic spectacle correction on children's academic performance.

Design: Systematic review and meta-analysis.

Methods: We searched 9 electronic databases from inception to July 26, 2021, for studies assessing associations between hyperopia and academic performance.

A review of corneal imaging methods for the early diagnosis of pre-clinical Keratoconus.

Background: Keratoconus (KC) is a corneal ectasia characterised by steepening corneal curvature, changes in refractive error and corneal thickness that result in visual impairment. Early signs of KC include displacement of the thinnest part of the cornea from the central position, changes in the corneal epithelial layer cell distribution, variations in the anterior corneal astigmatism/posterior corneal astigmatism relationship and a variation in corneal thickness. It is important that we review the corneal imaging methods for the diagnosis of preclinical KC.
