Influence of pseudoexfoliation syndrome on human lens transparency.

The possibility of a relationship between pseudoexfoliation syndrome (PEX) and lens opacity was studied. For this research, we used an opacity lens meter, the function of which is based on a back light scattering quantitation system. This instrument gives us an objective, reproducible, and numerically quantifiable measurement of the opacity of the lens. The lens opacity values measured in 91 PEX-positive eyes were compared with those measured in a control group of 100 normal eyes. This comparison showed that PEX-positive eyes always had higher lens opacity values than did normal ones, and this result was statistically significant (P = .01).
