Department of Ophthalmology, Chang Gung Memorial Hospital, Taiwan, Republic of China.

Gonioplasty with trabeculoplasty was used to treat 31 eyes of 25 patients (15 men and 10 women) with chronic angle-closure glaucoma. Ages ranged from 40 to 82 years (average, 60.4 yrs). The follow-up period was three to 36 months (average, 1 yr). During this time, 60% to 80% of eyes have maintained an intraocular pressure (IOP) less than 21 mm Hg and/or required less medication. The average IOP reduction was 7.9 mm Hg. Complications included focal, peaking, peripheral anterior synechiae in the lasered area in 19 of 31 eyes (61%), and permanently increased IOP in two of 31 eyes (6%). Gonioplasty was a useful method to differentiate between appositional angle closure and that due to peripheral anterior synechiae. After combined treatment, the chamber angle has remained open for more than a year in 60% to 80% of eyes.

D007498	Iris	The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.

D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

D003131	Combined Modality Therapy	The treatment of a disease or condition by several different means simultaneously or sequentially. Chemoimmunotherapy, RADIOIMMUNOTHERAPY, chemoradiotherapy, cryochemotherapy, and SALVAGE THERAPY are seen most frequently, but their combinations with each other and surgery are also used.

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
