Similar to retinitis pigmentosa in humans, Progressive Retinal Atrophy is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness.
It usually starts with decreased vision at night, or nyctalopia.
In Central Progressive Retinal Atrophy, the loss of the retinal pigment epithelium's ability to effectively process the photoreceptor outer segment (POS) and subsequent accumulation of POS material in the RPE and loss of function occurs. The loss of function of the RPE leads to photoreceptor degeneration.
