| Sumario: | Visual rehabilitation is based, in addition to the use of optical aids and neuroenhancement factors, on methods of visual training such as neurosensory techniques. Fixation training with microperimetry biofeedback (MBF) is a rehabilitation technique aimed to improve fixation stability in patients with eccentric viewing (EV) and unstable fixation due to central scotoma. One of the EV training difficulties is that people may tend to move their head or the viewing target instead of controlling their gaze. Moreover, such MBF results may not be preserved over time, and generally, training shall be repeated in clinical sites. The challenge is to create home-based training techniques that may help patients to preserve the MBF outcomes obtained in the clinical environment. The current pilot study explored the use of Augmented Reality Eyewear (ARE) to perform home-based eccentric viewing exercises on patients with large central scotoma after MBF. Methods: The change of fixation stability in ten patients with bilateral central geographic atrophy after eccentric viewing training was analysed. Five patients (control group) did not perform any training between the 4th and 5th MBF sessions. The other 5 (study group), after the 4th MBF session, performed home-based vision exercises with augmented reality eyewear (ARE). Results: We observed in the group with ARE a slightly improved fixation stability of +10.16% compared to the control group, where fixation stability showed a decrease. Conclusion: The results of this pilot study suggest that augmented reality eyewear with a dedicated home-based vision training application may help maintain fixation stability outcomes obtained during eccentric viewing training in vision centers with MBF.
