![]() Additionally, no treatment, including laser, has been shown to halt the progression of retinoschisis.Īlthough approximately three-quarters of lesions will have their most posterior extent postequatorial, only about three percent will progress posteriorly, so most still can be observed. The natural history is that this disease rarely progresses from where it's first observed, so resist lasering: most cases of posterior retinoschisis will not progress beyond 3 disc diameters from the macula and only a handful of cases of degenerative retinoschisis involving the macula have been reported. Senile retinoschisis is usually benign but complications include: May be difficult to distinguish from longstanding retinal detachment (RD): A smooth or bullous elevation is also seen in retinal detachments, but characteristics for a longer standing retinal detachment are RPE alterations and demarcation lines. ![]() OCT shows a break in the outer plexiform layer (OPL) in retinoschisis and not detachment of retina from RPE.Retinoschisis will not re-appose with scleral depression (no subretinal fluid to move out).Laser will blanch retinoschisis but not a rhegmatogenous retinal detachment (RRD).Check for an absolute scotoma with indirect ophthalmoscope perimetry: hold a scleral depressor on the observer's side of the condensing lens and document whether patient can see the depressor's shadow.Splitting at outer plexiform layer in senile retinoschisis Diagnostic procedures Associated with peripheral microcystoid degeneration.a relative scotoma in a retinal detachment). There will be no retinal tears, vitreous pigment cells, or demarcation lines unlike in a retinal detachment (RD).The inferotemporal location is most common.The vessels appear darker over the affected area. There can be an inner layer "beaten metal" or pitted appearance with minute glistening yellow-white surface dots, with minimal retinal pigment epithelium (RPE) alterations or atrophy.It will be dome shaped with uniform convexity and without corrugations often seen in a rhegmatogenous retinal detachment (RRD). It is relatively immobile transparent smooth or bullous elevation of inner layer wall.Typical senile retinoschisis is a shallow elevation of inner retinal layers, whereas the reticular kind has the traditional appearance of bullous elevation.Optos image of typical inferotemporal location of senile retinoschisis.
