Are There Special Tests to Diagnose Retinitis Pigmentosa?
Yes. Acuity Tests: This test measures the accuracy of your central vision at specific distances in specific lighting situations. Color Testing: This can help determine the status of your cone cells, the retinal cells that interpret color. Visual Field Test: This test uses a machine to measure how much peripheral vision you have. Dark Adaptation Test: This test will measure how well your eyes adjust to changes in lighting and can help the doctor better understand the current function of your rod cells, which are the retinal cells responsible for night vision. ERG Test: The ERG (electrophysiological test) records the electrical currents produced by the retina due to a light stimulus. The intensity and speed of the electrical signal becomes reduced as the photoreceptor cells degenerate.
