Plain-English summary
An 11.5-year-old female Przewalski's wild horse was brought in because her left eye was swollen and leaking fluid. Although her eye was not scratched, it was difficult to see inside due to swelling. After some treatment, her eye showed improvement, but over the next two years, she had some watery discharge from that eye. Eventually, a veterinary eye specialist found that the lens in her left eye had moved out of place, which made surgery to remove it more complicated. After the lens was successfully taken out, the horse moved to a new place and seems to have adjusted well, even though she may have lost vision in that eye. Since then, she has not had any more eye problems and has even given birth successfully.
Abstract
A 11.5-yr-old female Przewalski's wild horse (Equus caballus przewalskii) presented for unilateral blepharitis and drainage from the left eye. The left cornea was not ulcerated, and intraocular evaluation was hampered by severe corneal edema. The left eye appeared to respond positively to treatment with anti-inflammatories and a topical mydriatic agent. During the ensuing 2 yr, there were minor episodes of epiphora from the left eye. The discharge then increased, and a luxated lens was noted during an examination by a veterinary ophthalmologist as part of the preshipment examination. Initially, the lens was located in the anterior compartment but was in the vitreal compartment at the time of surgery, complicating the intracapsular extraction. After successful removal of the lens, the horse was transferred to a new institution without incident, where it appears to have adapted well to its probable loss of vision in the left eye. No further episodes of uveitis, corneal edema, or epiphora have been reported, and the horse has successfully foaled at the new institution.
