The long-term effects of iridectomy for primary acute angle-closure glaucoma. 1978

T Krupin, and K B Mitchell, and M F Johnson, and B Becker

Forty-nine eyes were treated with iridectomy for primary acute angle-closure glaucoma. Forty asymptomatic, normotensive fellow eyes were similarly treated. The duration of follow-up after surgery was 52.3 +/- 3.6 months. Thirty-seven (76%) of the eyes with acute attacks were cured by iridectomy alone and required no medical therapy. Twelve eyes (24%) developed increased intraocular pressure following iridectomy, but only one eye (2%) required filtering surgery. Eighty-eight percent of the asymptomatic, normotensive fellow eyes required no subsequent therapy, and none developed visual field defects. Visual acuity was unchanged in 22 of 49 (45%) of the acutely involved eyes and decreased more than six lines in 11 (22%) eyes. In the 40 fellow eyes, visual acuity was unchanged in 63% and decreased more than six lines in only one (2%) eye.

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.

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.

D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
D014792 Visual Acuity Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast. Acuities, Visual,Acuity, Visual,Visual Acuities
