Plain-English summary

A thoroughbred colt was found to have small eyes (microphthalmos) that were not the same size in both eyes, along with other eye issues like a small cornea and problems with the iris and lens. The colt also had colobomas, which are gaps or defects in the eye's structure, specifically in the back part of the eye. This case is compared to other similar cases in horses. The outcome of the colt's condition isn't specified, but it highlights the complexity of these eye abnormalities.

Abstract

A thoroughbred colt had bilateral but unequal microphthalmos together with microcornea, abnormalities of the iris and lens and posterior segment colobomas. The case is compared with other reports of microphthalmos and coloboma in horses.
