Assessment of retinal degeneration with optical coherence tomography in a dog

To report retinal image of in a 6-year-old male castrated poodle dog with a 2-month history of nyctalopia using optical coherence tomography (OCT).Ocular reflexes were present in both eyes and slit lamp examination showed anterior subscapular cataract in the right eye.There were fundus abnormalities in both eyes similar to retinal degeneration.Scotopic electroretinograms (ERGs) revealed significantly subabnormal amplitudes and prolonged implicit time, whereas photopic ERGs were better maintained, although far from normal.OCT of affected dogs revealed generalized retinal thinning much more than a normal age-matched dog.Therefore, OCT scanning is considered to be a useful method for retinal evaluation in dogs with retinal degeneration.
