Novel Clinical Manifestation of Congenital X-Linked Retinoschisis

X-linked Hereditary Retinoschisis.

AN X-linked degenerative retino-choroidal disease, hereditary retinoschisis, has been identified in the last 10 years. In milder cases the disease takes the form of radial macular degeneration, but in severe cases a grey sheet-like veil is attached to the detachment in the retinal vasculature, especially in the lower temporal quadrant. In differential diagnosis, according to Ricci (1960), a dom...

X linked retinoschisis.

Focal macular electroretinogram in X-linked congenital retinoschisis.

PURPOSE To study macular function of X-linked congenital retinoschisis (CRS) by focal macular electroretinogram (MERG). METHODS MERGs were recorded with 5 degrees, 10 degrees, and 15 degrees spots in 20 patients with CRS. Seventeen patients showed foveal schisis with little or no change in foveal fluorescein angiography (Group 1), and three patients showed advanced macular changes with nonspe...

X-linked retinoschisis: an update.

X-linked retinoschisis is the leading cause of macular degeneration in males and leads to splitting within the inner retinal layers leading to visual deterioration. Many missense and protein truncating mutations have now been identified in the causative retinoschisis gene (RS1) which encodes a 224 amino acid secretory retinal protein, retinoschisin. Retinoschisin octamerisation is implicated in...
