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.
1. Understand the relationship and association of epiretinal membrane with VMT
2. Recognize retinoschisis as a complication of VMT
