Effect of retinal detachment surgery on the course of preexisting open-angle glaucoma.
In 11 of 12 eyes with chronic simple glaucoma after surgery for retinal detachment, intraocular pressures were decreased for one to 5 1/2 years without any antiglaucomatous treatment. No further deterioration in the state of the optic disks or the visual fields occurred in any of these eyes. In all 12 fellow eyes antiglaucomatous treatment is still being administered. The operation employed in nine of the 11 cases consisted of an encircling silicone rubber band shortened by 15 to 20% of its length when placed around the eyeball before tapping subretinal fluid. An episcleral silicone implant was placed under the encircling ban in seven of these eyes. Kinking and possibly narrowing of the long posterior ciliary arteries by the encircling silicone band probably caused the ciliary hyposecretion and the resultant hypotony.
