A case of multiple unilateral corneal epithelial inclusion cysts in a dog

A three-year-old neutered female Labrador cross was presented for investigation of two corneal epithelial inclusion cysts affecting the left eye. The aetiopathogenesis of the cyst formation was suspected to be traumatic. The cysts were removed successfully by superficial keratectomy, followed by a third eyelid flap. Histologically, both lesions were represented by cystic formations lined with multi-layered squamous epithelium, consistent with stromal inclusion of surface corneal epithelium. Complete recovery was achieved, and there was no recurrence at six month follow-up.
