title: Treatment of neovascular senile maculopathy at the foveal capillary free zone with red krypton laser.
abstract: Sixty-eight eyes with neovascular senile maculopathy involving the capillary free zone that were assigned randomly for red krypton laser photocoagulation were followed for two years and compared to 55 eyes with the same disease that were not treated. In the majority of the studied eyes there was a decline of visual acuity during the follow-up period. However, an increase in visual acuity was encountered in one third of treated eyes, but no increase in the untreated eyes. The extent of visual acuity deterioration was greater in the nontreated than in the treated eyes. Eyes that were treated when visual acuity was between 6/9-6/60 generally belonged to a better final visual acuity group than those eyes that were treated when visual acuity was less than 6/60. The technique of red krypton laser photocoagulation is described, the rationale for this treatment is discussed, and the results of the treatment are evaluated.
