Circumferential argon laser photocoagulation for prevention of retinal detachment

Abstract

Circumferential argon laser photocoagulation was administered as preventive treatment for retinal detachment in 53 eyes with extensive areas of lattice degeneration and/or retinal breaks and at least one additional high-risk factor for retinal detachment. Laser burns were applied in several continuous rows 360 degrees around the peripheral retina at the junction between the posterior border of the lesions and the unaffected retina. The retina posterior to the treated areas remained attached in 51 eyes (96.2%) during a mean follow-up period of 85.8 months (range 6 months to 18 years). The treatment did not affect visual acuity. The only complication was the appearance in 2 eyes (3.8%) of a delicate epiretinal membrane which, however, did not require surgical intervention.
