Pneumoretinopexy with SF6 as an adjuvant to other modalities for Retinal Detachment Surgery.
Pak J Ophthalmol Jan ;14(2):69-72.

Increasing awareness of the properties of long-acting gases and a closer understanding of overcoming their potential hazards have made gases essential tools in the management of various vitreoretinal problems. From January 1994 to May 1996, of the 84 vitreoretinal surgeries performed at the eye department Civil Hospital, Karachi, 28 eyes of 26 patients were selected for treatment with intraocular gas. 16 were males (61.5%) and 10 were females (38.5%). Ages varied from 16 years to 68 years with a mean age of 40 years. 16 eyes were phakic, 4 had extracapsular cataract extraction and another 4 had posterior chamber IOL implant. 3 had intracapsular cataract extraction and one eye had a ruptured posterior capsule. One patient had ectopia lentis. History of trauma was present in 2 cases (7%). Myopia more than 3 diopters was present in 7 eyes (25%). In all these cases SF6 gas was used as an adjuvant to other modalities for treating retinal detachment. Anatomical attachment after first operation was achieved in 22 eyes (78%). Of the remaining 6 eyes, two retinae were further attached by subsequent surgeries. The final anatomical success rate was 85.8%. Visual acuity better than 6/36 was achieved in 17 cases (60.7%), while better than 3/60 was present in 22 cases (78.5%). Regarding complications, 7 cases developed lens changes, 5 of which were reversible (7.1%). IOP was raised temporarily in 5 and permanently in one (3.5%). Lid swelling due to postoperative positioning was present in most of the cases. One eye developed endophthalmitis.
