The low vision treatment of patients with retinitis pigmentosa (RP) has evolved through an understanding of the needs of the patient with extreme peripheral field constriction. Patient care involves four main areas: 1) best refraction and simple magnification, including the possibility of electronic type magnification for reading; 2) control of glare and determination of the proper illumination for reading and mobility; 3) use of field enhancement procedures for sighting and for mobility, including the understanding of cane travel and scanning techniques; 4) additional counseling and ancillary care. Through the methods described, patients who might have been poor prospects for low vision care 15 or 20 years ago, may now be able to function at much higher levels.
