INTRAOPERATIVE OCULAR MANOMETRY IN SILICONE OIL-FILLED EYES WITH A BOSTON TYPE 1 KERATOPROSTHESIS.

PURPOSE: To demonstrate a novel technique to measure the intraocular pressure in silicone oil (SO)-filled eyes with Boston Type 1 keratoprosthesis (KPro) during intraocular surgery.

METHODS

In this retrospective case series, an ocular manometer that is predicated on a continuous fluid column between a pressure sensor and interior of the eye was designed and used to directly measure intraocular pressure during intraocular surgery in SO-filled eyes with KPro.

RESULTS

Six eyes of six patients were included in the study. The indications for SO injection with ocular manometry were hypotony in five patients, and endophthalmitis and complex retinal detachment with proliferative vitreoretinopathy in one patient. All patients had a successful reinflation of their globes without any evidence of SO underfill, without evidence of SO overfill, and without progression of glaucomatous optic neuropathy. Visual acuity increased in five eyes and was maintained in one eye.

CONCLUSION

Intraoperative ocular manometry is a safe and effective technique in determining intraocular pressure in SO-filled eyes with KPro.
