PURPOSE: To evaluate prophylactic laser treatment of the macula in reducing the risk of visual loss in the fellow eye of patients with a retinal pigment epithelial tear caused by age-related macular degeneration in the first eye.
METHODS: In a prospective study, 12 patients with a retinal pigment epithelial tear in one eye caused by age-related macular degeneration and drusen in the fellow eye received prophylactic laser treatment of the retina in their fellow eyes and were followed up for 2 years or more after prophylactic treatment.
RESULTS: In 12 fellow eyes that received prophylactic laser treatment, a reduction in best-corrected visual acuity to 20/80 or worse occurred in one (8%) of 12 eyes in the first year and two (18%) of the remaining 11 eyes in the second year after treatment. The cumulative risk of visual loss in the treated fellow eye was 25% in 2 years.
CONCLUSIONS: In historical control subjects in a natural history study of patients with retinal pigment epithelial tear in one eye, central visual loss occurred in 16 (37%) of 43 eyes in the first year and in seven (30%) of 23 eyes in the second year for a cumulative loss of 59% in the first 2 years. Compared with these historical control subjects, our findings suggest that visual loss in the fellow eyes of patients with a retinal pigment epithelial tear in the first eye is reduced by prophylactic low intensity laser photocoagulation of the macula.
