• Bilateral retinal detachment (RD) occurred in 13% of 737 patients, with an interval between detachments of up to 30 years. Bilateral RD was more common in male patients and in those having more than 3 diopters of myopia. Detachment in the second eye was caused by retinal breaks in previously observed degeneration in 43% and in unsuspected diseased retina in 57%. A significant number of patients with bilateral RD had multiple breaks. Aphakic RD occurred in bilateral RD and in unilateral RD patients at a comparable frequency; 28% of bilateral (mean duration, four years) and 35% of unilateral aphakic RDs occurred within one year of cataract surgery. Symptoms from retinal breaks were not reliable prognostic factors; only 39% of patients had warning before RD. Patients with bilateral RD had more reoperations with fewer successes, factors suggesting greater severity than unilateral RD.
