Understanding higher‐order aberrations in keratoconus

Optometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

Aniridia‐associated keratopathy: Clinical and molecular mechanisms of disease progression and emerging therapeutic targets

Acta Ophthalmologica, Volume 104, Issue 6, Page 604-615, September 2026.
Abstract Congenital aniridia is a rare genetic disorder primarily caused by pathogenic variants of the PAX6 gene. It leads to various panocular anomalies, including aniridia‐associated keratopathy (AAK). This review highlights recent insights into its pathogenesis, focusing on clinical staging, microstructural changes in the cornea and molecular ...

Case series: The role of retinal ischemia in the pathogenesis and clinical manifestation of diabetic retinopathy

Optometry and Vision Science, Volume 103, Issue 8, August 2026.
ABSTRACT Purpose To highlight retinal ischemia as an important component of diabetic retinopathy (DR) pathogenesis, a significant prognostic factor, and a driver of various DR complications, including neovascularization. We aim to describe the main features of ischemic areas that can be identified through fundoscopy, color fundus photography, optical ...
