What is the condition called that involves hereditary pigmentary degeneration of the retina causing loss of peripheral vision?

The condition involving hereditary pigmentary degeneration of the retina that causes loss of peripheral vision is known as retinitis pigmentosa. This progressive eye disease is characterized by the breakdown of photoreceptor cells in the retina, specifically affecting rods, which are responsible for peripheral and night vision. As the condition advances, individuals experience a narrowing of their visual field, often leading to significant peripheral vision loss, while central vision may remain intact until the later stages of the disease.

Retinitis pigmentosa is genetically inherited, with various forms linked to different genes. The onset and progression can vary widely among affected individuals, often starting in childhood or adolescence. Understanding this condition is crucial for managing its impact on daily life, as patients may need to develop adaptive strategies to cope with vision loss. Other options listed—such as macular degeneration, glaucoma, and cataracts—represent different eye conditions that do not primarily cause the specific symptoms associated with retinitis pigmentosa.
