Dynamic Light Scattering Device (DLS) Study of Age-Related Changes in the Lens and Cataracts

NCT00007215 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 24

No results posted yet for this study

Summary

This study will use a newly developed instrument called dynamic light scattering device (DLS) to examine age-related changes in the human lens and to study the causes and development of cataracts. DLS uses a low intensity laser light (similar to that used in supermarket checkouts) to measures lens cloudiness. It detects changes in the human lens at the earliest stages, when anti-cataract treatment would be most effective in reversing, delaying or preventing cataract formation.

Patients 18 years of age and older with cataracts and normal volunteers between the ages of 18 and 70 years may be eligible for this study. Participants will have a standard eye examination, including a vision check, pressure measurement, lens examination using DLS and examination of the retina. Photographs of the lens or retina, or both, may be taken.

This study does not involve treatment. No anti-cataract medications will be given.
