患有色素性视网膜炎（RP）的患者视力不足，无法从光学低视力辅助设备中获益，闭路电视（CCTV）阅读机经常可以帮助他们。将 RP 患者对 CCTV 的使用与黄斑病患者（即仅具有中心暗点的组与还具有额外周边视野损失的组进行比较）以及“正常”对照组的使用进行比较。患有 RP 的人通过使用黑色背景上的白色打印可以提高表现，而黄斑变性受试者则没有显着的偏好。速度限制似乎是机器施加的限制的函数。两组人经常使用“光学辅助工具”阅读得更快。
Patients with retinitis pigmentosa (RP) who have insufficient vision to benefit from optical low vision aids are frequently helped by the closed-circuit television (CCTV) reading machines. RP patients'' use of the CCTV is compared with that of patients with maculopathy (i.e. a group with a central scotoma only, is compared to a group which also has additional peripheral field loss), and with that of a "normal" control group. The performance of people with RP is improved by using white print on a black background, while macular degeneration subjects have no significant preference. Speed limits appear to be a function of restrictions imposed by the machine. Both groups frequently read faster with "optical aids".
