Branch Retinal Artery Occlusion- OCT Tissue Changes
You should look at the normal retinal photos first as a basis for comparison. This 70 year old woman was seen for a sudden loss of her superior vision in her left eye and was diagnosed with a branch retinal artery occlusion. Her color fundus photograph on initial visit of 2-27-2017 shows a cherry red spot (yellow arrow) with retinal whitening encircling the fovea from 1 oÕclock to 9 oÕclock due to regional nonperfusion in the distribution of the blocked branch retinal artery (black arrow). Optical coherence tomography (OCT) on 2-27-2017 shows ischemic hyperrelectivity of the inner retina (green arrow). One month later the ischemic whitening has resolved (white arrow) however the inner retina has atrophied with a decrease in thickness on OCT (blue arrow).
