Abstract

Patients who had posterior synechiae associated with uveitis,IOL mplantation, vitrectomy, underwent Nd-YAG synechiolysis had been treated with topical corticosteroids and surgical iridectomy. Even minimal dilatation of the pupil by Nd YAG synechiolysis enable the patient to read and the surgeon to postpone cataract surgery and evaluate optic disc or fundus. Also, pupil block may be treated by detaching the synechiae.18 Patients (20 eyes) with posterior synechiae underwent Nd-YAG synechiolysis at Kangnam St.Mary's Hospital from November 1997 to August 1998. An average of 17.14 +/-6.43mJ laser were used. The average prelaser pupil size was 3.78 +/-0.98 mm ;postlaser, 5.13 +/-1.27 mm.This change was statistically significant (p<0.01). Microhyphema and pigment dispersion developed in 4 eyes. However,no significant long-term complications occurred, and there were no obvious lenticular damage and pupil abnormality. Because this laser treatment is relatively safe and offers some possibility of visual improvement, we recom-mend Nd-YAG synechiolysis,but only if performed by an experienced laser microsurgeon.
