Nonclassical ultrasonographic presentation of retinal detachment: Blindness in a 21‐year‐old gelding with equine recurrent uveitis

Equine Veterinary Education, EarlyView.
Summary A 21‐year‐old gelding, with a history of equine recurrent uveitis, was presented for a chronic nonhealing corneal ulcer. Ophthalmic examination of the right eye revealed a deep corneal ulcer, with the presence of corneal neovascularisation, mild diffuse corneal oedema and hypopyon. Additionally, the gelding was blind from the affected eye.

Bilateral simultaneous cataract surgery and intraocular lens implantation in an adult female chimpanzee (Pan troglodytes) inducing monovision

Veterinary Ophthalmology, Volume 28, Issue 2, Page 457-464, March 2025.
Abstract Background Cataract is the major cause of visual impairment in humans. Phacoemulsification with intraocular lens (IOL) implantation is the standard technique for cataract treatment with a high success rate. In a few cases, the surgical cataract procedure and lens implantation have been applied in non‐human primates.

Imaging characteristics of delayed surface calcification in hydrophilic intraocular lens models

International Ophthalmology, 2013
We report two cases of opacified explanted intraocular lenses (IOL).The first lens was explanted from a cataract patient, then treated in vitro with trypsin/ethylene-diamine-tetra-acetic acid. The second hydrophilic acrylic IOL was explanted from a patient who had undergone sulphur hexafluoride (SF6) gas endotamponade surgery to repair a retinal ...
