Abstract

AbstractObjectiveTo report the corneal clarity outcome following lamellar keratectomy of arcus lipoides corneae secondary to canine hypothyroidism and report a unique retinal manifestation of systemic disease.Animal StudiedFour‐year‐old spayed female Sheepdog‐Poodle canine.ProcedureLamellar keratectomy OD.ResultsBilateral severe arcus lipoides corneae was noted in the initial presentation. Bilateral, symmetric, and multifocal bullous retinal detachments were observed at subsequent visits. Biochemical testing revealed hyperlipidemia presumed to be associated with primary acquired thyroiditis. Corneal clarity and visual behaviors were significantly improved following unilateral lamellar keratectomy with no evidence of recurrence within the year following surgery. Bilateral retinal detachments and hyperlipidemia resolved months after initiation of thyroxine supplementation. Corneal lipidosis in the untreated eye remained static.ConclusionsLamellar keratectomy is a viable surgical option for the treatment of arcus lipoides corneae. Hypothyroidism should be considered a differential diagnosis for spontaneous, bilateral, multifocal, and serous retinal detachments.
