Fluorescein angiography of the optic nerve head in the elderly.

Interpretation of fluorescein angiography of the optic nerve head is somewhat difficult due to its peculiar vasculature. Three early phases can commonly be observed: 1) retrolaminar and prelaminar filling; 2) prelaminar filling; 3) superficial capillary filling. The authors describe the characteristics of the fluorescein angiography of norman optic nerve hed in the elderly. The interpretation of these signs is also discussed.
