Retinitis pigmentosa (RP) is a group of rare eye diseases that affect the retina (the light-sensitive layer of tissue in the back of the eye). RP makes cells in the retina break down slowly over time, causing vision loss.
RP is a genetic disease that people are born with. Symptoms usually start in childhood, and most people eventually lose most of their sight.

Definition of retinitus pigmentosa:
The NEIO already has terms for retina and disease, but not genetic disease. Not sure if the correct term from OGMS should be constitutional genetic disease or acquired genetic disease.
Not sure what the best way is to represent "slow breakdown".
