Field-expansion devices, infrared blocking sun lenses and contrast enhancing filters may be helpful. Periodic optometric follow-up is also important. Perform visual fields several times a year, and evaluate for cataract or macular edema at least annually. Most patients with RP are diagnosed in the second or third generation of life. Because of the insidious nature of the disorder, the earliest indicators are often objective findings rather than subjective complaints.
Some presentations are extremely subtle, particularly in the early stages.
Perform a critical evaluation on all patients presenting with complaints of nyctalopia or peripheral field loss. Impress upon these patients also that, although they cannot be cured, they still require periodic examination to assess their status as well as manage their ongoing refractive needs. Also stress the potential for visual enhancement through low-vision devices and vision rehabilitation.
