This patient was sent in for a white retinal lesion. What is it?
This is a vertical cut through the optic nerve and peripapillary area. Here there is a retinal elevation that involves the inner retinal elements and in particular the nerve fiber layer and ganglion cell layer. There is also a large central cyst. On the surface of the retina there is some vitreous haziness. This lesion corresponded with a translucent/whitish lesion (video). B-Scan also demonstrated a hyper reflective mass located in the superficial retina (video).
The patient was treated for astrocytic hamartoma.
In this tip's accompanying 16 min. video, we'll review:
- The differential diagnosis of this lesion
- The systemic diseases associated with astrocytic hamartoma
- The location and types of glial tissue in the retina
The differential diagnosis of an elevated mass in the superficial retina should include lesions derived from neurons and supportive cells, and include astrocytic hamartoma.
