The evaluation of 430 consecutive eyes (87.5% from male, 12.5% from female patients) showed a leakage point with uniform dye spread in 93%. In 7%, a smoke-stack phenomenon was observed. The number of leakage points reached from 1 (71.6%) to 7 (0.2%). Most leakage points were found in a 1-mm-wide ring-shaped zone starting 0.5 mm from the center of the fovea. Beyond this zone the incidence dropped rapidly with the exception of the upper nasal quadrant. Of the leakage points, 33.2% were located in the upper nasal, 21.2% in the lower nasal, 19.0% in the upper temporal, and 14.8% in the lower temporal quadrant. Leakage points occurred more than 3 mm away from the center of the fovea in 11.8%. The papillomacular bundle contained 25.4% of the leakage points. Leakage points in recurrences were located within 1 mm of the primary leakage point in 80% of the cases.
