title: Advances in vitreoretinal surgery: macular hole repair and perfluorocarbon liquids.
abstract: 1. Idiopathic macular hole was once thought to be an untreatable disorder. During the past several years, surgical techniques have evolved that allow for closure of the macular hole, with restoration of vision in many cases. 2. Perfluorocarbon liquids are an important class of compounds that are under investigation for use in vitreoretinal surgery. The use of these compounds facilitates the performance of intraocular surgical maneuvers in certain difficult-to-manage vitreoretinal disorders. These substances have a high specific gravity and are able to displace water within the eye, facilitating reattachment of the retina in certain types of retinal detachments such as those associated with proliferative vitreoretinopathy and giant retinal tears. PFCLs also aid in the removal of intravitreal lens fragments or foreign bodies and in the repositioning or removal of dislocated intraocular lenses. 3. Ophthalmic nurses and technicians can play an important role in initial screening for these patients. Detection of symptoms may lead to early diagnosis of idiopathic macular hole and subsequent treatment. Patient education emphasizing topics such as the importance of strict postoperative face-down head positioning may be critical for successful surgery.
