Anterior Lens Subluxation and Pseudohypopyon

open access: yesCase Reports in Ophthalmological Medicine, Volume 2026, Issue 1, 2026.
Asteroid hyalosis is a benign condition caused by refractile particles in the posterior segment, typically discovered incidentally during eye examination. Rarely, these particles may migrate to the anterior chamber due to lens subluxation, trauma, or pressure changes and mimic a pseudohypopyon or iris metastasis.

Acute Angle‐Closure Glaucoma Secondary to Vitreous Prolapse Following Ocular Trauma

open access: yesCase Reports in Ophthalmological Medicine, Volume 2026, Issue 1, 2026.
Secondary acute angle‐closure glaucoma (AACG) caused by vitreous prolapse in a phakic patient is exceedingly rare. We report a case of AACG secondary to vitreous prolapse, occurring 2 weeks after orbital trauma in a 34‐year‐old male healthcare worker.
