During a pre-purchase (soundness) examination of a six-year-old Quarterhorse, the left eye appears normal. However, the right eye appears as in the image.

Question	Answer		Article
What is this lesion?	Cataract due to prior uveitis and subsequent posterior synechiae.		Link to Article
The horse is performing adequately. Do you recommend purchase?	No. Subsequent episodes of uveitis would be likely in the left eye, and very possibly as a future problem in the right eye. Over 50% of horses will have uveitis as a bilateral condition in time. Traumatic uveitis may have caused the left eye lesion, but unless you actually attended the trauma, medicolegal logic dictates a failed soundness examination.		Link to Article
