Abstract:
150 eyes (85 patients) of angle closure glaucoma treated with Nd: YAG laser iridectomy were analyzed to reveal that the basic factors leading to posterior synechiae were the dosage and duration of miotics used. In the cases with posterior synechiae, miotics of higher dosages were used before and after the laser iridectomy and also a longer duration before the operation than in cases without the sequelae. With posterior synechiae, the pathological damages to the optic nerve worsened with time to affect the visual acuity and the control of IOP, and also interfered with fundus examination and cataract extraction when needed. The study indicated that proper dosage of laser energy,intensive postoperative use of topical steroids, early dilatation of the pupil, and appropriate application of mioties were conducive to the prevention of posterior synechiae.
