Recurrence of conjunctival exuberant granulation tissue in a pony

Abstract

SummaryA 22‐year‐old pony mare was presented at the Equine Hospital of the Faculty of Veterinary Medicine with a pedunculated exuberant granulation tissue (EGT) located at the lateral bulbar conjunctiva of the right eye. The granulation tissue, diagnosed by histology, grew over three and a half weeks after a superior and inferior Gundersen inlay flap procedure. The pony's underlying ocular pathology was diffuse corneal oedema, suspected to be related to immune‐mediated keratitis affecting the endothelium. Despite several surgical resections, topical corticosteroid treatment, intralesional injection of methylprednisolone acetate and electrosurgical cauterisation, the combination of a ligature at the peduncle base of the mass, intralesional injection of methylprednisolone acetate and removal of the facemask seemed to be the most efficient treatment. The mass did not recur after 33 months of follow‐up. Similar healing tissue has been reported, secondary to surgical ophthalmic procedures in human medicine, in which it is called a conjunctival pyogenic granuloma (CPG).
