OCT Tip 236 was originally published on July 1st, 2022.
This 72-year-old presented with poor vision ou. Why?

Analysis
In this OCT, the inner retina is normal for the most part. There are a few areas of hyper reflectivity in the ganglion cell/inner plexiform layer, one of which is consistent with a micro aneurysm. The outer retina is within normal limits. On examination, the patient was noted to have scattered microaneurysms and hemorrhages in the mid-periphery (video).
The patient was treated for both ocular ischemic syndrome (OIS) and diabetic retinopathy.
In this tip's accompanying 7 min. video, we'll review:
- The differential diagnosis of microaneurysms
- When to consider OIS as a diagnosis
- How OIS is diagnosed

OCT Tip
In any patient presenting with microaneurysms, consider the possibility of OIS
