Resumo
Background: There is no hope of preserving vision at the terminal stage of glaucoma, and surgical treatment is indicated in thesecases. Among the various surgical techniques used, eye evisceration with implantation of an intrascleral prosthesis provide thebest cosmetic results. Even though eye evisceration with prosthesis implantation represents an excellent treatment option forterminal glaucoma, reports on the use of this technique in dogs are scarce in the current literature. The aim of this work is to reporta case of a dog with end-stage glaucoma subjected to eye evisceration surgery and implantation of an intrascleral prosthesis.Case: A 7-year-old bitch mixed breed with a history of glaucoma secondary to uveitis with no response to medical therapy wasreferred to the Ophthalmology service of the University Veterinary Hospital of Coimbra (HVUC), Portugal At the ophthalmicexamination, the glaucomatous left eye was buphthalmic, with congested episcleral blood vessels, mydriasis, and posterior luxation of the lens; there was no response to threat or obfuscation, no direct and consensual pupillary reflex, nor pupillary reflexesto chromatic light. The intraocular pressure (IOP) was 55 mmHg, and the Schirmers tear test (STT-1) result was 19 mm/min.Ophthalmoscopy revealed attenuated retinal blood vessels and a pale optic papilla with mild excavation. The right eye wasfunctional, with all parameters assessed on examination and by tests within the normal ranges for the species. An ultrasoundexamination of the left eye confirmed the presence of posterior luxation of the lens and buphthalmia in the absence of intraocularneoplasm. In view of the patients history and results of the clinical examinations, a surgical approach was indicated to treat theglaucomatous eye. The patients tutor requested a surgical procedure that...(AU)
