Retinitis Pigmentosa

Retinitis Pigmentosa represents a group of inherited eye diseases affecting the peripheral retina resulting in progressive loss of side and night vision. This type of vision impairment often begins in childhood and progresses over time. While walking individuals with tunnel vision may bump into objects in their side vision. Optical devices that minify the image (like hotel room peepholes), sometimes called reversed telescopes, may be of value. When fields of view become very narrow sighted guides, long canes, and guide dogs become very helpful.
