Collie eye anomaly : case presentation and discussion

Abstract

Navarre was presented on 7/6/95 at two months of age, along with 9 other siblings, for routine ophthalmologic examination to check for manifestations of the Collie Eye Anomaly (CEA). Clinial manifestations of CEA include choroidal hypoplasia, optic nerve colobomas, scleral ectasia, and possible retinal detachment. Indirect ophthalmoscopy revealed that Navarre had moderate choroidal hypoplasia and a large optic nerve coloboma in his left eye in additon to a detached retina, with resultant blindness, in his right eye. Due to the guarded to poor prognosis for continued vision long term in his left eye, Navarre was donated to the Ophthalmology Service at Cornell University, College of Veterinary Medicine for study and adoption or euthanasia.
