摘要

X-linked juvenile Retinoschisis (XLRS) is a hereditary vitreoretinal dystrophy characterized by schisis-like retinal splitting at the posterior pole with variable involvement of the peripheral retina. Additional funduscopic findings may include a golden metallic fundus reflex and, less commonly, other retinal abnormalities. The disease is caused by pathogenic variants in the RS1 gene. It follows an X-linked recessive inheritance pattern, resulting in clinical manifestation almost exclusively in males. XLRS typically manifests in early childhood as non-specific visual impairment. If XLRS is suspected, early retinal imaging using OCT should be performed. Therapeutic approaches primarily involve carbonic anhydrase inhibitors. Gene therapy represents a potential causal treatment option.
