Abstract
PURPOSE: To describe a new classification of stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR). DESIGN: Retrospective case series and literature review. PARTICIPANTS: A total of 17 patients from 5 institutions. METHODS: Detailed case history, multimodal imaging, and genetic testing were reviewed for patients with macular schisis without a known predisposing condition. Patients with a stellate appearance centered on the fovea with correlating confirmed expansion of the outer plexiform layer (OPL) by optical coherence tomography (OCT) were included. Exclusion criteria included a family history of macular retinoschisis, a known genetic abnormality associated with retinoschisis, myopic traction maculopathy, epiretinal membrane, vitreoretinal traction, optic or scleral pit, or advanced glaucomatous optic nerve changes. MAIN OUTCOME MEASURES: Clinical features, anatomic characteristics, and visual acuity. RESULTS: A total of 22 eyes from 16 female patients and 1 male patient with foveomacular schisis were reviewed from 5 institutions. Initial visual acuity was >/= 20/50 in all eyes (mean, 20/27), but visual acuity in a single eye decreased from 20/20 to 20/200 after the development of subfoveal fluid. The refractive status was myopic in 16 eyes, plano in 3 eyes, and hyperopic in 2 eyes. Three eyes had a preexisting vitreous separation, and 19 eyes had an attached posterior hyaloid. Follow-up ranged from 6 months to >5 years. CONCLUSIONS: In this largest known series of patients with SNIFR, all patients demonstrated splitting of the OPL in the macula with relatively preserved visual acuity (>/= 20/40) except in a single patient in whom subretinal fluid developed under the fovea.
