Fluorescein angiography is a specialized imaging technique primarily used to visualize the blood vessels in the retina. This procedure involves the intravenous injection of fluorescein dye, which travels through the bloodstream to the retina. As the dye flows through the blood vessels, a camera captures a sequence of images at various intervals. This allows for the assessment of the retinal blood flow, detection of abnormalities such as leaks, blockages, or malformations in the blood vessels, and the diagnosis of various ocular conditions such as diabetic retinopathy, retinal vein occlusion, and age-related macular degeneration.

The other options, while related to ocular health, do not pertain to the primary function of fluorescein angiography. For example, measuring intraocular pressure is typically done with tonometry, while assessing optic nerve health often involves other imaging techniques or examinations such as optical coherence tomography. Evaluating the overall eye structure can include various imaging modalities but is not specific to fluorescein angiography, which focuses specifically on the vascular network in the retina.
