What is retinitis pigmentosa?

Retinitis pigmentosa is a progressive genetic disorder that results in the degeneration of the retina, particularly affecting the photoreceptor cells, which are responsible for converting light into visual images. This condition typically leads to progressive vision loss, starting with peripheral vision and eventually affecting central vision as well. The genetic nature of retinitis pigmentosa means that it is often inherited, which distinguishes it from conditions caused by environmental factors or temporary health issues.

In contrast, the other options describe different types of vision-related problems but do not accurately represent retinitis pigmentosa. Temporary vision blurriness might arise from a variety of factors, but it does not relate to the chronic and degenerative nature of retinitis pigmentosa. A type of eye infection implies an acute inflammatory reaction that would not align with the hereditary degeneration of the retina associated with retinitis pigmentosa. Similarly, while high blood pressure can lead to conditions affecting the eye, it does not specifically cause retinitis pigmentosa; instead, the disorder is inherently linked to genetic factors affecting retinal health.
