Pigmentary dispersion syndrome is a precursor of pigmentary glaucoma whose prevalence in the urban population of USA was found to be 2.45%. We evaluated its prevalence during ocular screening examinations among normal Israelis. We screened for excessive pigmentation on the corneal endothelium with the slit-lamp and determined in each patient best corrected visual acuity, intra-ocular pressure (after mydriasis), condition of the anterior segment, cup-disk ratio, posterior segment abnormalities and questioned about history of any ocular disease and family history of glaucoma. 374 patients (mean age 49 +/- 11) were examined on 10 consecutive days. In 5.9% excessive corneal endothelial pigmentation was found. Intra-ocular pressure (after mydriasis) averaged 15.52 +/- 1.93 mm Hg as compared to 14.73 +/- 2.04 among the rest of our study population, (p = 0.01). The prevalence of suspected pigmentary dispersion syndrome among young adults in Israelis is high.
