Ciliary muscle thickness and intraocular pressure before and after latanoprost

Optometry and Vision Science, Volume 103, Issue 6, June 2026.
ABSTRACT Purpose To test the hypothesis that a larger, latanoprost‐induced intraocular pressure (IOP) reduction is associated with a thicker ciliary muscle. Methods Participants (N = 31) were healthy with the following details: mean ± SD age 24.8 ± 3.3 years.

The Prophylactic Effect of Dexmedetomidine 0.008% Versus Brimonidine 0.2% on IOP Elevation After Nd: YAG Laser Capsulotomy

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Posterior capsule opacification (PCO) is a common post‐cataract surgery complication treated with Nd:YAG laser posterior capsulotomy, which may cause intraocular pressure (IOP) spikes and threaten vision. Brimonidine and apraclonidine are widely used to prevent such elevations.

Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

Acta Ophthalmologica, Volume 104, Issue 3, Page 267-279, May 2026.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated
