Other Tests

Other tests used to evaluate senile retinoschisis include the following:

  • Fundus drawings
  • Visual field plotting (sharp absolute scotoma in senile retinoschisis; sloped relative to absolute in retinal detachment)
  • Low-power retinal laser test spot to rule out subretinal fluid, ie, retinal detachment (in very difficult cases)

Histologic Findings

Two histologic types of senile retinoschisis have been identified.

Flat type also is termed typical degenerative retinoschisis. Characteristics of this type include splitting at the outer plexiform layer, usually confined anterior to the equator, and not associated with holes.

Bullous type also is termed reticular degenerative retinoschisis. Characteristics of this type include splitting in the nerve fiber layer, often extends posterior to the equator, and often has outer layer holes that may lead to retinal detachment when associated with inner layer holes.
