Summary

This study will test whether a new non-invasive technique can quickly and precisely measure retinal metabolism (the amount of energy retinal cells use). The retina is the part of the eye that sends information to the brain.

Participants in current NEI studies who have age-related macular degeneration (AMD), diabetic retinopathy, or von Hippel-Landau disease may be eligible for this study. Healthy volunteers will participate as controls. Patients with AMD must be 60 years of age or older; those with VHL disease or diabetic retinopathy must be 18 or older.

Participants undergo the tests and procedures required in the NEI study in which they previously enrolled. In addition, for the current study, they undergo metabolic mapping. For this procedure, the subject's eyes are dilated, and different amounts of low-level light are shone into the eye to see how different cells respond with changes in metabolism. Measurements are taken while the subject breathes room air and while he or she breathes medical grade oxygen for about 1 minute. The entire procedure takes about 15 minutes.
