Pigmentation of the anterior chamber angle in normal and pseudoexfoliative eyes.

Anterior chamber angle pigmentation was gonioscopically graded in 833 persons recruited for the KEYS (Kuopio Eye Survey) during 1989. Pseudoexfoliation was observed in 8.5% in either eye from those born in 1924, the figure being 13.2% for those born in 1914. Anterior chamber angle pigmentation was found to be significantly heavier in eyes with pseudoexfoliation.
