Abstract

Objective: To describe the clinical presentation, treatment, and outcome of four horses with severe corneal edema caused by suspected endothelial disease treated with a superficial keratectomy and Gundersen inlay flap and to determine whether this procedure (i) reduces corneal edema, (ii) reduces ocular pain, (iii) eliminates recurrent corneal ulceration, and (iv) improves vision in these horses. Animals studied: Four horses met inclusion criterion of (i) diagnosis with endothelial disease by a board-certified veterinary ophthalmologist and (ii) surgical treatment with a superficial keratectomy and Gundersen inlay flap. Procedure: Retrospective medical record review of included horses was used to determine breed, age and sex of included horses, as well as details of medical and surgical therapy, and visual outcome. Results: Four horses were presented with a complaint of focal corneal edema that progressed to diffuse corneal edema. Epithelial bullae and ulceration were present in all cases. The disease process was unresponsive to standard medical treatment with a hyperosmotic agent and topical and systemic anti-inflammatories. However, treatment with a superficial keratectomy and Gundersen inlay flap performed under general anesthesia was associated with (i) a significant decrease in corneal edema, (ii) increased comfort, (iii) elimination of corneal ulceration, and (iv) retention of vision postoperatively with little to no need for medical therapy. Follow-up time was 15, 12, 6, and 3 months. Conclusions: The superficial keratectomy and Gundersen inlay flap may provide a surgical alternative to chronic medical treatment of severe corneal edema in horses.
