Argon laser peripheral iridotomies in the treatment of primary angle closure glaucoma. Long-term follow-up. 1982

A L Robin, and I P Pollack

We analyzed the long-term results after argon laser peripheral iridotomy in 98 eyes of 54 patients with primary angle closure glaucoma. During a mean follow-up period of about five years, visual acuity, intraocular pressure, medication changes, and the need for filtration surgery or cataract surgery were used to evaluate the amount of possible damage that had resulted from laser iridotomy. Eyes treated with the argon laser did not appear to differ significantly from those of similar patients, described in other series, in which surgical iridectomy had been used as the therapy of choice. Argon laser peripheral iridotomy appears to be a laser peripheral iridotomy appears to be a safe and effective means of treating primary angle closure glaucoma.

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.
