Purpose: To present a patient with stellate nonhereditary idiopathic foveomacular retinoschisis found with multimodal imaging. Methods: A single case was evaluated. Results: A 70-year-old woman presented with schisis cavities in the outer plexiform layer in the left eye on macular optical coherence tomography. No leakage was detected by fluorescein angiography. After ruling out other causes of nonvasogenic cystoid maculopathy, the patient was diagnosed with stellate nonhereditary idiopathic foveomacular retinoschisis. After 5 years, the best-corrected visual acuity remained stable. The retinoschisis in the left eye had resolved, and cystoid spaces appeared in the lower portion of the macula in the right eye despite the absence of vitreomacular traction. There was no history of ocular procedures or medication use that could have affected the course of the pathology during the intervening period. Conclusions: This case emphasizes the importance of performing multimodal imaging to monitor the characteristics of stellate nonhereditary idiopathic foveomacular retinoschisis as they evolve.
