“…However it was expensive, difficult to purchase, difficult to hold and its narrow field of view limited its usefulness. 162,163 Night-scopes were the next development. These devices amplified the incoming light to create monochromatic green images.…”

Retinitis pigmentosa (RP) is a leading cause of blindness and visual disability in younger people. Optometrists have a major role in detecting RP and in reducing the visual disability associated with RP. This review summarises the literature relating to visual function in people with RP, with particular attention given to night‐blindness, visual acuity decrease and visual field contraction. The range of low vision aids available for people with RP is reviewed and suggestions given on aids that have been found to be most successful. Most importantly, this review overviews the range of services available to people with RP and emphasises how optometrists need to work with a network of professionals to ensure the best possible visual outcomes for people with RP. Particular mention is made of current findings relating to orientation and mobility training, driving, sensory substitution and adaptive technology. The modern optometrist needs to be aware of the multiple needs of people with RP and have the ability to link them with the professionals best able to help them.

“…This might have been caused by the lack of appropriate training for adaptation to using a 49 minified image and/or transmittance of the see-through display; notably, the walking time with the device improved with each repetition (average walking time: practice one, 32.88 ± 13.76 s; practice two, 27.38 ± 10.31 s; walking test, 24.86 ± 8.66 s). As discussed in previous reports [8,9,11,12], the improvement of mobility in darkened conditions is explained by the effect of visual field expansion through minification of the view as well as by the ability to see the objects. In this study, we used only a micro lens (f3.8 F2.0) to create the necessary conditions, the magnification percentage of the image, however, can be adjusted easily by changing the camera lens.…”

“…Since the 1970s, several types of devices have been evaluated to address mobility problems due to night blindness [7][8][9][10][11][12][13][14]. Berson et al [7] first reported the helpfulness of a night vision enhancement device based on a military light-intensifier.…”

“…In the 1970s, night vision systems have been introduced to alleviate orientation and mobility problem experienced by RP people under reduced illumination [5]. More recently, Spandau et al [6] and Hartong [7] investigated the potential benefits of night vision goggles on mobility at night in realistic environments.…”
