The use of intraocular gases. The results of sulfur hexafluoride gas in retinal detachment surgery.

The results of SF6 gas in 69 retinal detachment cases managed with nonvitrectomy techniques are presented. Of 57 cases followed six months, 64.9% were reattached and 61.4% showed stabilization of visual acuity at 20/60 or better or improvement in vision from the preoperative level. Visual and anatomical results were similar between 16 giant tear cases managed with SF6 and a similar previous series from the same institution managed with air. Complications possibly attributable to gas were development or progression of mild cataract changes in 27% of phakic patients and transient elevation of intraocular pressure in 26% of all patients on the first preoperative day. Presumed central retinal artery occlusion occurred in four patients with elevated pressure, with permanent loss of light perception in three diabetic patients. In selected cases where other methods or air will not suffice, SF6 can be useful if used cautiously.
