Retina

Case 34

Patient Presentation: A 59-year-old male presented for a routine 6-month follow-up with his retinal surgeon for assessment of his epiretinal membrane. Vision is 20/25 OD and 20/40 OS. His OS OCT macula is shown below:

Question: What abnormality is NOT visualized in the patient’s OCT image?

Question: What is the diagnosis?

Retinoschisis involving the macula can be difficult to differentiate from cystoid macular edema. On OCT, retinoschisis changes resemble intraretinal pseudo-cystic spaces exhibiting "strand-like" separations (or vertical pillars) as opposed to the oval or circular shaped intra-retinal fluid in CME. To definitively differentiate these two entities, an IVFA can be performed. There will be no leakage seen on IVFA in retinoschisis.

Learning Objectives:

1. Understand the relationship and association of epiretinal membrane with VMT

2. Recognize retinoschisis as a complication of VMT
