Plain-English summary
A 1-day-old miniature horse filly was brought in for eye problems that were present since birth. The filly had a large, red mass in one eye and no visible eye in the other. Ultrasound showed that the right eye was filled with abnormal tissue, while the left eye was underdeveloped. Unfortunately, because the filly was permanently blind due to these severe congenital eye defects, she was humanely euthanized.

Abstract
A 1-day-old miniature horse filly was presented to the University of Florida Veterinary Ophthalmology service for evaluation of multiple ocular anomalies which were present from birth. Protruding from the right orbit was a large, fluctuant, red, dry and variably ulcerated mass. A globe could not be appreciated clinically in the left orbit. Ocular ultrasound of both orbits was performed. This revealed a lobular, hypo-echoic structure filling the right orbit, with multiple hyperechoic septations; normal ocular structures were not identified. Ultrasound of the left orbit revealed a microphthalmic eye, with a well-defined, hyperechoic structure in the vitreous that was thought to be the lens. Due to irreversible blindness, the foal was humanely euthanized. Histopathology and immunohistochemistry of the orbital contents revealed bilateral microphthalmos with cyst, a congenital defect rarely reported in the veterinary literature.
