P4HA2 Participates in Pathogenesis of Refractive Error by Regulating Collagen Posttranslational Modification and Extracellular Matrix Balance. [PDF]

Hum Mutat
Myopia represents a refractive anomaly characterized by impaired vision resulting from a misfocused image in front of the fovea. Although numerous genes linked to high myopia (HM) have been identified, the exact etiology and pathogenesis mechanisms of HM remain predominantly obscure. In a prior investigation, a mutation in the P4HA2 gene was identified

Clinical Effectiveness of Facility and Accuracy of Accommodation in Diagnosis of Non Strabismic Binocular Vision Anomalies in Young Adults: A Prospective Cross-sectional Observational Study [PDF]

Journal of Clinical and Diagnostic Research, 2022
Introduction: Orthoptic evaluation is highly recommended in children and young adults to diagnose binocular dysfunctions. Binocular vision dysfunctions may hamper academic performance in children. Accommodative facility and accommodative accuracy are

Using a video‐based eye tracker to analyse the binocular near‐reflex dynamics response

Ophthalmic and Physiological Optics, Volume 43, Issue 6, Page 1540-1549, November 2023., 2023
Abstract Purpose This study presents a novel video‐based eye‐tracking system for analysing the dynamics of the binocular near‐reflex response. The system enables the simultaneous measurement of convergence, divergence and pupillary size during accommodation and disaccommodation to aid the comprehensive understanding of the three‐component near‐reflex ...
