A patient presents with a red eye two months after losing their vision. What is the cause of visual loss?
Analysis
On this OCT, there is significant inner retinal thinning. The NFL and the ganglion cell layer are dramatically reduced in thickness. The outer retinal layer is normal; the external limiting membrane and ellipsoid zones are clearly visible. The patient’s earlier OCT showed significant inner retinal thickening (video).
The patient was treated for retinal thinning from an earlier central retinal artery occlusion.
In this tip's accompanying 12 min. video, we'll review:
- The most common causes of iris neovascularization
- The incidence of neovascularization in retinal artery occlusion
- Why CRVO is much less likely to be associated with NVI/NVG than CRVO
OCT Tip
While CRVO is the most common type of retinal vascular occlusion associated with NVI, this finding can be seen in about 10-15% of patients with CRAO.
