Iridocorneal Angle Abnormality in Dogs

Category: Eye
Breeds documented: 1
Published sources: 5

Overview

The iridocorneal angle is the space where the cornea, the clear front covering of the eye, meets the iris, its colored part. This area helps drain fluid from inside the eye. If its supporting tissue or width is abnormal, fluid drainage can become restricted. These changes raise the risk of glaucoma, a painful rise in eye pressure that can damage sight, but an abnormal angle does not by itself mean glaucoma is present.

Signs to watch for

Redness if glaucoma develops
A cloudy eye if glaucoma develops
An unusually large pupil with glaucoma
Eye pain or loss of sight if glaucoma develops

Some angle defects are present from birth, and the structure may change as a dog ages.

Emergency Go to an emergency vet immediately if your dog's eye becomes red and painful.

Diagnosis and tests

The key screening test is gonioscopy, in which a vet uses a special lens to view the eye's drainage angle. The result describes the shape and width of the angle and the severity of any abnormality. Gonioscopy identifies structural changes, while a tonometer measures pressure inside the eye.
