Orthotropic Outcome With Spectacle Correction in a Pediatric Case of Refractive Esotropia and Anisometropic Amblyopia

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Early and accurate spectacle correction in children with refractive esotropia and anisometropic amblyopia can restore orthotropia, improve visual acuity, and prevent long‐term amblyopia. Timely diagnosis, careful refractive assessment, and individualized management are crucial.

Birefringent properties of the human cornea in vivo : towards a new model of corneal structure [PDF]

The fundamental corneal properties of mechanical rigidity, maintenance of curvature and optical transparency result from the specific organisation of collagen fibrils in the corneal stroma. The exact arrangement of stromal collagen is currently unknown

Risk Factors of Keratoconus in High School Students in Trinidad and Tobago: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background Keratoconus (KC) is the most common form of keratectasia that is associated with impaired vision and reduced quality of life, especially in adolescents. This study aims to identify and assess the risk factors associated with KC among high school students in Trinidad and Tobago (T&T).

Astigmatism-type-specific impact of peripheral corneal thickness on anterior keratometric profile changes after temporal clear corneal incision cataract surgery

Scientific Reports
Postoperative astigmatism remains a concern after temporal clear corneal incision (TCCI) cataract surgery, especially in eyes with preexisting corneal astigmatism. This study investigated whether peripheral-to-central corneal thickness ratios can predict
