Abstract:
A total of 0.3ml of 100% sulfur hexafluoride(SF6) was injected into vitreous cavity with a single shot or two 0.15ml shots, and the time dependent intraocular pressure changes were compared. Intraocular pressure was monitored at 5 minute intervals for 60 minutes after injection. Immediately after a single shot injection, remarkable intraocular pressure elevation(85mmHg, mean)was observed, which returned, however, to normal level within 15 minutes. Intraocular pressure elevation was milder when a smaller bolus of gas(0.15ml)was separately injected twice. No re-elevation of intraocular pressure was noted with either method after the initial return to normal.
