Objective : To determine whether the HARP camera could be useful as an aid for patients with low vision, particularly retinitis pigmentosa (RP) with the chief complaint of night blindness. Methods : We tried an experiential experiment on patients with RP. Nine patients with RP were set up to experience using the HARP camera indoors, and one of those patients used the camera outdoors. Visual function was evaluated and each patient was surveyed by questionnaire. A total of 50 RP patients of the Japanese Retinitis Pigmentosa Society (JRPS) also participated in the experiment and in the questionnaire survey. Results : The HARP camera was useful for all RP patients, in both indoor and outdoor experiments. Fifty percent of the respondents rated the camera as "Excellent" and 30% as "Good, " indicating that a total of 80% of the 50 RP patients had a positive impression of the camera. Conclusions : Although the camera is large and the monitor needs improvement, the camera shows potential for application to patients with night blindness who retain a certain degree of visual function.
