—Air is frequently used to re-form the anterior chamber after intraocular surgery. Though the roles of long-lasting intraocular gases such as sulfur hexafluoride and perfluorocarbons are well established in vitreoretinal surgery,1 they have not been used in anterior segment surgery. However, the expansile properties of these gases and their longer persistence compared with that of air may offer advantages in the management of selected anterior segment problems. We report a case of persistent flat anterior chamber following glaucoma filtration surgery that was unresponsive to numerous choroidal taps and anterior chamber re-formations and in which perfluoropropane was successfully used.
Report of a Case.
—A 69-year-old man was evaluated for possible cataract surgery on the left eye. Visual acuity in the right eye was light perception because of end-stage glaucoma. Visual acuity was 20/200 OS, a moderately dense nuclear sclerotic cataract was present, the intraocular pressure was elevated,
