Clinical, histopathological and immunohistochemical characterization of a novel equine ocular disorder: heterochromic iridocyclitis with secondary keratitis in adult horses

VETERINARY OPHTHALMOLOGY, 18(6), 443–456.

By: N. Pinto n, R. McMullen n, K. Linder n, J. Cullen n & B. Gilger n 

author keywords: endotheliitis; iridocyclitis; keratic precipitates; keratitis; retrocorneal membrane; uveitis
MeSH headings : Animals; Cornea / pathology; Female; Horse Diseases / diagnosis; Horse Diseases / pathology; Horses; Iridocyclitis / diagnosis; Iridocyclitis / pathology; Iridocyclitis / veterinary; Keratitis / diagnosis; Keratitis / pathology; Keratitis / veterinary; Male; Uvea / pathology
TL;DR: Heterochromic iridocyclitis with secondary keratitis (HIK) is characterized by uveal inflammation with pigment dispersion and suspected corneal endothelial dysfunction and may not respond to therapy and enucleation may ultimately be required to ensure the horse's comfort.

By: R. McMullen n, M. Davidson n, N. Campbell n, J. Salmon n & B. Gilger n 

MeSH headings : Animals; Anterior Chamber / surgery; Anti-Bacterial Agents / administration & dosage; Anti-Bacterial Agents / therapeutic use; Euthanasia, Animal; Eye Enucleation / methods; Eye Enucleation / veterinary; Horse Diseases / surgery; Horses; Lens Implantation, Intraocular / methods; Lens Implantation, Intraocular / veterinary; Lens, Crystalline / anatomy & histology; Lens, Crystalline / surgery; Lenses, Intraocular / veterinary; Refraction, Ocular / physiology; Refractive Errors / therapy; Refractive Errors / veterinary; Refractive Surgical Procedures / methods; Refractive Surgical Procedures / veterinary
TL;DR: Investigation of intraocular lens (IOL) implant strength to approximate emmetropia in horses found insertion of 30-D (enucleated globes) and 25-D IOL implants (adult horses) resulted in overcorrection of refractive error. (via Semantic Scholar)

Long-term outcome after implantation of a suprachoroidal cyclosporine drug delivery device in horses with recurrent uveitis

Veterinary Ophthalmology, 13(5), 294–300.

By: B. Gilger n , D. Wilkie *, A. Clode n, R. McMullen n, M. Utter, A. Komaromy *, D. Brooks*, J. Salmon n

author keywords: cyclosporine; equine; implant; recurrent uveitis
