OCT-Angiography in Neuro-ophthalmology

Optical Coherence Tomography (OCT) has become one of the most important imaging modalities in ophthalmology, since its invention in 1990's. OCT is a noninvasive technique based on the principle of low-coherence interferometry, which generates high-resolution, cross-sectional images from backscattered light, and helps to assess the structural changes in different retinal diseases. Low contrast between capillaries and retinal tissue hinders OCT to be used to monitor vascular changes.
