Abstract

Because of unpredictable corneal changes, evisceration and implantation of a silicone prosthesis does not always lead to a satisfying cosmetic result. This paper describes the use of an intraocular silicone prosthesis in combination with an extraocular glass prosthesis and shows a followup of two and a half years in a nonexperimental study. An intraocular silicone prosthesis was implanted after evisceration of the left eye in a five-month-old Bernese mountain dog. A glass prosthesis was fitted four weeks after evisceration. Two and a half years after the operation, the dog is in good health and free of medication. No short-term or long-term complications were seen. The owners do not have trouble with handling the glass prosthesis. The combination of both prostheses shows a perfect solution to retrieve a normal looking and moving eye after evisceration.

Highlights

In both human and veterinary ophthalmology several surgical options are described to treat an end-stage glaucomatous eye that does not respond to medical therapy.The easiest and fastest procedure is enucleation of the eye

The extraocular prosthesis was kept in place by its shape, the third eyelid and the eyelids resting over the border of the prosthesis

Summary

Introduction

In both human and veterinary ophthalmology several surgical options are described to treat an end-stage glaucomatous eye that does not respond to medical therapy. Transscleral cyclophotocoagulation with diode laser or cryotherapy in combination with an Ahmed gonioimplantation in dogs with primary glaucoma has a success rate of approximately 76%, and most of the patients still need longterm medication [12, 13]. This method is reserved for acute glaucomatous eyes, which are still visible or are believed to have a change to regain vision. This paper shows a followup of two and a half years of a dog with an intraocular silicone prosthesis combined with an extraocular glass prosthesis after evisceration.
