Résumé
@#Stellate nonhereditary idiopathic foveomacular retinoschisis(SNIFR)is a new catagory of foveomacular retinoschisis, defined by spokelike appearance on fundus which is similar to X-linked congenital retinoschisis, and without agenetic predisposition. SNIFR is most commonly unilateral and female predominance. The retinoschisis in SNIFR occurs primarily in outer plexus split(OPL), and coexists with inner retinal or peripheral retinoschisis in some cases. The characteristics of SNIFR on multimodal fundus imaging are summarized in the review. The pathogenesis of SNIFR is not yet elucidated. At present, there is not practicable systematic treatment for this disease. Topical dorzolamide therapy or vitrectomy may improve the vision and foveomacular retinoschisis.
