retinitis pigmentosa
Let an agent explain retinitis pigmentosa in general terms, describe inheritance and testing with attribution, route people to eye care and genetic services, and support living with vision loss without individual medical advice.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain retinitis pigmentosa in general terms, describe inheritance and testing with attribution, route people to eye care and genetic services, and support living with vision loss without individual medical advice.
A group of inherited retinal degenerations in which photoreceptor cells progressively die, causing night blindness, narrowing of the visual field and eventual loss of central vision, caused by variants in many genes with different inheritance patterns and occurring alone or in syndromes such as Usher syndrome; retinitis pigmentosa is diagnosed by eye examination and genetic testing and managed with low vision support and emerging gene and cell therapies.
What it is for: Inherited retinal degeneration.
It can be explain the condition and its course; describe inheritance and testing; route to eye and genetic services; support living with vision loss.
Distinguishing features

What it looks like
Not visible externally; pigment changes in the retina on examination.
How it is recognised
Progressive photoreceptor loss
Night blindness and tunnel vision
Macular degeneration affects central vision first
