Penetrating Eye Injury in a Dog: A Case Report

A four-year-old, male German Shepherd dog with severe pain in the left eye following a corneal perforation with a foreign body was examined. An ophthalmic examination revealed conjunctival hyperaemia and pancorneal dense oedema, preventing a diagnosis of deeper structures of the eye and lowered IOP. Vision testing was missing or impossible to detect. Ultrasonography showed a solid hyperechoic line protruding through the iris and lens into the vitreous and minor posterior lens displacement. The dog qualified for immediate surgical treatment. Intraoperative ophthalmic examination revealed a rupture of the anterior hyaloid membrane with vitreous herniation, posterior lens subluxation, lens capsule rupture and a torn iris. Partial iridectomy and intracapsular lens extraction (ICLE) was conducted. Slit-lamp biomicroscopy revealed iridodonesis and a gradual reduction of the corneal oedema, leading to complete transparency in the bottom two-thirds of the area on Day 12 after surgery. Direct and consensual PLR was sluggish and the dazzle reflex was positive. An electroretinographic examination confirmed normal activity of the retina.

Abstract


A four-year-old, male German Shepherd dog with severe pain in the left eye following a corneal perforation with a foreign body was examined. An ophthalmic examination revealed conjunctival hyperaemia and pancorneal dense oedema, preventing a diagnosis of deeper structures of the eye and lowered IOP. Vision testing was missing or impossible to detect. Ultrasonography showed a solid hyperechoic line protruding through the iris and lens into the vitreous and minor posterior lens displacement. The dog qualified for immediate surgical treatment. Intraoperative ophthalmic examination revealed a rupture of the anterior hyaloid membrane with vitreous herniation, posterior lens subluxation, lens capsule rupture and a torn iris. Partial iridectomy and intracapsular lens extraction (ICLE) was conducted. Slit-lamp biomicroscopy revealed iridodonesis and a gradual reduction of the corneal oedema, leading to complete transparency in the bottom two-thirds of the area on Day 12 after surgery. Direct and consensual PLR was sluggish and the dazzle reflex was positive. An electroretinographic examination confirmed normal activity of the retina.
