Optical coherence tomography angiography (OCTA) en face images of a patient with unilateral stage 3 NVI in the left eye (b, c). The right eye (a) shows no obvious pathologic vasculature on exam or on en face OCTA. In the left eye, a dense network of small-caliber vessels can be observed surrounding the pupil inferiorly, nasally and superiorly. Temporally, big vessels are present. Slit lamp photography is presented for comparison (c). While large-caliber vessels are easily appreciated on slit lamp photography, detection of smaller capillaries can be challenging (c).
