Summary
A fungal corneal stromal abscess in a thoroughbred yearling was treated with penetrating keratoplasty after medical therapy failed. Surgical intervention led to a successful outcome without impacting the horse
Area of Science:
- Veterinary Ophthalmology
- Equine Surgery
- Mycology
Background:
- Corneal stromal abscesses can impair vision in horses.
- Fungal infections are a potential cause of deep stromal abscesses.
Purpose of the Study:
- To describe a case of fungal corneal stromal abscess in a thoroughbred yearling.
- To evaluate the efficacy of penetrating keratoplasty for treatment.
Main Methods:
- A yearling presented with corneal opacity and iridocyclitis.
- Medical management was unsuccessful.
- Penetrating keratoplasty was performed for diagnosis and treatment.
Main Results:
- Histopathology revealed fungal hyphae and necrotic neutrophils in the deep stroma and Descemet's membrane.
- Bacterial and fungal cultures were negative.
- The horse recovered with a corneal scar that did not affect its racing career.
Conclusions:
- Penetrating keratoplasty is an effective treatment for fungal corneal stromal abscesses in horses.
- Early diagnosis and surgical intervention can preserve vision and athletic function.
