Study Summary
This study will assess the value of improved magnetic resonance imaging (MRI) techniques to study the lens of the human eye. Knowledge of how cataracts develop and progress has been hampered by the lack of human tissue available for study; MRI may provide an effective means for learning more about this eye disease. Normal volunteers between 18 and 70 years of age may be eligible for this study. Participants will undergo a medical history and complete eye examination, including vision assessment, eye pressure measurement, lens and retina examinations, and photography of the eye. MRI scans will be scheduled for a second visit. For this procedure, the volunteer's pupils are dilated and he or she then lies on a stretcher that is moved into a cylinder containing a magnetic field. A device similar to a welder's helmet is placed on the head. Attached to the device are an imaging probe and a small blinking light. The probe receives radio signals from the eye that a computer converts into images. During imaging, the participant gazes at the blinking light; this helps keep the eyes from blinking and wandering. Scan times vary from 2 to 10 minutes; the total time for the study is less than an hour.
