- Description
- Senile retinoschisis in a 40-year-old woman showing a very large outer layer hole and a smaller one just above it. The inner layer is intact as shown by the blood vessels running through this layer. Note the prominent, sharp, yellow border at the upper and left edges of the large hole. This is caused by an inward rolling of the border of the outer layer and tends to be much more common along the posterior edges of holes in the outer layer in retinoschisis. This is an example of a schisis detachment with onset before age 40. It extends posteriorly to a .2½ disc diameters from the macula and has remained essentially "arrested" at this location for more than 17 years. A similar symmetrical "schisis-detachment" is present in the fellow eye.
