Dr. Lowder:

My 11 year old TB/Qh cross has begun walking into things while coming into the barn at night in the past week. He has not experienced any trauma to his eye or had any kind of infection. There is no film or any other visible obstruction of the eye, nor is the eye tearing or sensitive to bright light. The vet has checked him using a flashlight to test his reaction to light and has found that the left eye does not respond as quickly as the right eye. He seems fine during the day, but seems to be afraid to come in at night alone without another horse to lead him. The vet and I are both confused as to what could be causing this condition. Any thoughts?
Thanks!

Kamma,

I am sorry but I don’t know what is wrong with your horse either. Moon blindness (equine recurrent uveitis) is a painful condition and the eye usually has a whitish appearance to it. Ask your vet to refer you to a veterinary ophthalmologist.

Thanks, Dr. Lowder
