Due to the dry, windy environmental conditions we live in, there have been an increased incidence of corneal ulcers (scratches on the eye). The signs of a corneal ulcer include: redness, tearing, squinting and/or cloudiness. These signs depend on the severity of the ulcer. Due to the environment in which horses live, it is safe to assume that all ulcers are infected. The infectious agents can either bacterial, fungal or both.
The majority of corneal ulcers are uncomplicated and superficial. These are easily treated and heal very quickly. Others, however, are complicated and may require hospitalization and months of treatment. It is sometimes difficult to tell these two apart, which is why it is important to consult a veterinarian for a diagnostic workup of any corneal ulcer.
The outcome of many corneal ulcers is dependent on early diagnosis and treatment. The complications that can arise from an ulcer include: cataracts, permanent corneal scarring, decreased vision and equine recurrent uveitis.
