COMPLICATIONS ASSOCIATED WITH THE USE OF 5000 – CENTISTOKE SILICON OIL AFTER VITREO – RETINAL SURGERY

Complication Centistoke Silicon Oil

Abstract

Purpose: The purpose of the study was to report and compare the complication rates associated with use of silicon oil after vitreo-retinal surgery.

Methods: This was a prospective hospital based study spanning over a period from January 2004 to June 2005. A total of 69 patients with different vitreo-retinal diseases were operated by a single surgeon using standard three ports pars plana vitrectomy technique and 5000–centistoke silicon oil. Depending upon the intra-operative situation, additional procedures were performed including use of an encircling band, relaxing retinotomy and use of perfluorocarbon liquids.  

Results: The major post-operative complications observed were, development of cataract in 46 (85.18%) out of 54 patients, early post-operative raised intra-ocular pressure (IOP>25 mmHg) in 28 (40.57%) patients, keratopathy (including corneal edema, corneal abrasions and band keratopathy) in 15 (21.73%) patients, emulsification of silicon oil in 5 (7.26%) patients, glaucoma in 5 (7.26%) patients on final follow-up and ocular hyopotony in 1 (1.44%) patients. Retinal re-attachment in 35 (72.92%) and retinal re-detachment in 13 (27.08 %) patients. Visual out-come was, improved visual acuity in 45 (65.23%) patients, preserved (un-changed) in 10 (14.49%) patients and was reduced in 14 (20.28%) patients.

Conclusions: The use of silicon oil in vitreo-retinal surgery offers definite advantages however, its complications particularly cataract, glaucoma and kertopathy lead to worries about its use for prolonged retinal temponade.
