This patient presents 3 months after reporting sudden visual loss. Why?
Analysis
There is marked thinning of the retina. This is predominantly in the inner retina; the ganglion cell layer and nerve fiber layer are markedly reduced in thickness. There is also some subtle fluid located in the outer plexiform/outer nuclear area.
The patient was treated for significant vascular pruning and an embolus on clinical exam.
In this tip's accompanying 10 min. video, we'll review:
- The systemic evaluation of an intraretinal embolus
- The differential diagnosis of retinal thinning
- The importance of an arterial “cut-off” sign on angiography
OCT Tip
Any patient with inner retinal thinning should warrant consideration of remote retinal artery occlusion.
