Image of the Month (IOTM) is a collection of interesting clinical cases with high quality images for all relevant imaging modalities (ex: color fundus, OCT, OCTA, FAF, FA, En Face, Red-free, choroidal vasculography (CVG), anterior imaging) and other clinical results if relevant (ex: visual field plots). Each case is submitted by an eye care professional using one of Topcon’s industry-leading OCT devices.

Case background

Topcon TRC-50DX optic nerve photo (A) of a 7 year old girl’s right eye, showing a likely congenital vascular variant. A retinal artery can be seen exiting the optic nerve vertically into the posterior vitreous, forming a loop. Image B is a fundus photo that shows the patient’s normal vasculature, outside of the loop exiting the nerve. Patient’s exam is otherwise unremarkable.
