Children and adults from Ann Arbor, Michigan, LaJolla, California, and the NEI clinic may be enrolled in this study. Participants will receive medication as described above for the safety trial. They will be observed daily for the first week and will have repeat eye examinations, including photographs, at months 3, 6, 9 and 12 to see if the crystals have decreased. Patients will keep a daily diary of the condition of both eyes.
