ABSTRACT : Objective to study the intraocular pressure pesponse after pneumatic retinopexy procedure
                      Method Using a Goldmann applanation tonometer, intraocular pressure was measured preoperatively, and 1, 30, 60 and 90 minutes after gas injection, and then once daily for four days in 17 eyes with rhegmatogenous retinal detachment that were injected 0.3 ml of perfluoropropane gas for pneumatic retinopexy
                      Results Preperative intraocular pressure was 8.18 ? 4.52 mmHg (mean ? SD). All eyes had an immediate rise in intraocular pressure after gas injection. Two eyes had central retinal artery occlusion lasting for less than 10 minutes. Intraocular pressure at 1, 30, 60, and 90 minutes after gas injection were 74.59 ? 6.44 (mean ? SD), 20.59 ? 7.58, 14.29 ? 5.72 and 13.00 ? 3.24 mmHg, respectively. All eyes had normal intraocular pressure throughout four days after the gas injection.
                      Conclusion Following pneumatic retinopexy, all eyes had initial intraocular pressure elevation and returned to normal level within 60 minutes after gas injection.
