Abstract

In a prospective study, 41 eyes with well-defined extrafoveal and juxtafoveal choroidal neovascular membranes were randomly assigned to be treated with two different laser wavelengths. Eighteen eyes were treated with an argon green laser 514.5 nm (AGL) and 23 eyes with a dye red laser 630 nm (DRL). In all cases, the authors studied the central visual field changes after laser photocoagulation by comparative analysis of the results of visual field indices before and after laser treatment. The differences between pre- and post-laser values for mean sensitivity and mean defect were not statistically significant (p>0.05), whereas those for loss variance (p=0.0052) and corrected loss variance (p=0.0004) were. Laser photocoagulation produces a deeper scotoma in the treated area, but improves sensitivity in the remainder of the central visual field. The differences in visual field indices between the group treated with AGL and the group treated with DRL were not statistically significant.
