Zonular traction tufts of the peripheral retina were found in 15% of the 750 autopsy cases studied, were bilateral in 15%, and, thus, were present in 9% of the 1,500 eyes examined. These lesions were present at birth and occurred with equal frequency in all decades beyond the first. Of the affected eyes, 64% had one lesion, 33% had two to three, and 3% had four or more lesions. Eighty-one percent of the tufts were found in the nasal quadrants, 58% in the inferior quadrants. Six percent of the tufts were longer than 1.00 mm; 16% were based farther than 0.5 mm behind ora serrata. Trophic complications included holes in the base of tufts (partial in 10%; full-thickness in 4%). Tractional complications included rupture of tuft (5%) and full-thickness tears (three cases).
