CHRONIC HYPOTONY AND UVEITIS MANAGED WITH PARS PLANA VITRECTOMY, SILICONE OIL TAMPONADE, AND PERMANENT KERATOPROSTHESIS.

PURPOSE

We report a case of silicone oil placement after Boston type 1 keratoprosthesis implantation for improvement and maintenance of intraocular pressure in a patient with chronic hypotony secondary to chronic uveitis.

METHODS

Observational case report.

RESULTS

A 54-year-old woman with a history of bilateral chronic panuveitis and subsequent hypotony presented with progressive corneal decompensation and band keratopathy in her better-seeing left eye. Corrected distance visual acuity in her left eye declined from count fingers at 3' to hand motion. In an effort to clear the visual axis and stabilize intraocular pressure, implantation of a Boston type 1 keratoprosthesis combined with pars plana vitrectomy and silicone oil injection was performed. Postoperatively, the intraocular pressure improved to the midteens and vision improved to count fingers at 4'with a follow-up of 2 years.

CONCLUSION

Pars plana vitrectomy and injection of silicone oil after placement of a Boston type 1 keratoprosthesis can successfully improve and maintain intraocular pressure in eyes affected by chronic uveitis with ciliary body atrophy and chronic hypotony. This strategy effectively reverses such problems as hypotony maculopathy, disk swelling, scleral infolding, and corneal failure.
