This retina has retinitis pigmentosa. Note the “bone spicule” deposits in the peripheral retina and the close-to-normal appearance in the macula region.

This retina has retinitis pigmentosa. Note the dark “bone spicule” deposits in the peripheral retina.

Retinitis Pigmentosa, on the other hand, is a disorder of the rods, so that night vision and the ability to see to the side (Tunnel Vision) are reduced. Macular vision can remain near normal so often individuals with Retinitis Pigmentosa can read and walk in bright sunlight. Devices that expand the visual field (Image Minifiers and Field Viewers) can help individuals with “Tunnel Vision” see more to the side, helping with mobility and other activities.
