Long‐term test and retest reliability of clinical vergence testing

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose To establish long‐term reliability measures for vergence testing in a control population of adolescents. Methods Healthy participants between 12 and 17.5 years with normal binocular vision were recruited from 10 clinical sites. Cover test, near point of convergence (NPC), positive and negative fusional vergences, vergence facility (12∆

Deep learning–empowered low‐cost portable automated refraction system: A solution to the inadequate effective correction rate of refractive errors in resource‐limited areas

Ophthalmic and Physiological Optics, EarlyView.
Abstract Aims To develop and validate a low‐cost, portable automated refraction system (Tongren Digital Sight, TRDS) using deep learning and infrared eccentric photorefraction to improve refractive error correction in resource‐constrained settings. Methods This randomised controlled crossover trial enrolled 282 participants (18–60 years of age) at ...

The role of astigmatism in myopia development, myopia progression and myopia control

Ophthalmic and Physiological Optics, EarlyView.
Abstract Aims/Purpose Myopia arises primarily due to excessive axial elongation and is associated with an increased risk of ocular complications and visual impairment, particularly in high myopia. Although astigmatism may have implications on refractive development, the role of astigmatism in myopic eye growth and the effectiveness of myopia control ...
