Authors' recommendations:
Evidence of safety and effectiveness for retinal implants considered in this summary was low level. However, comparator treatments do not exist and the cases considered in two experimental trials (Yanai et al 2007, Caspi et al 2010) were shown to experience gains in visual percept from use of the device. The results of Yanai and colleagues indicated that increasing the number of electrodes may not directly translate to improved resolution of percept for patients, whereas Caspi and co-workers undertook experiments that showed a stronger connection between increased electrode number and improved resolution. The studies included very small sample sizes, which may explain discrepancies in the results.The level of evidence assessed was low. Retinal prostheses to treat retinitis pigmentosa (and possibly age-related macular degeneration) are currently at a developmental stage, especially within an Australian context. No further action by HealthPACT is required at this time.
