Abstract

Multidisciplinary Sciences Science & Technology Science & Technology - Other Topics
Aim of this study was to explore the optimal training interval and times of microperimetric biofeedback training (MBFT) in maculopathies. Twenty-nine patients with maculopathies were divided into two groups: daily training (Group A) or alternate daily training (Group B). Both groups underwent 15 MBFT sessions. We compared the BCVA, reading speed, and fixation stability at baseline, after 5, 10, 15 sessions. After 15 sessions of MBFT, all visual parameters in both groups improved. There was a significant increase in BCVA after 5 sessions in both groups (P=0.016, and P<0.001 respectively), but Group A showed further improvement after 10 sessions (P<0.001). Regarding reading speed, Group A showed significant improvement from baseline after 15 sessions(P=0.020), Group B improved significantly after 5 sessions (P=0.047) and continued to improve after 10 sessions (P=0.030). Additionally, P1 and LgBCEA of Group A significantly improved after 10 sessions (P=0.001, and P=0.001 respectively), while Group B significantly improved after 5 sessions (P=0.002, and P<0.001 respectively). There was no significant difference in visual outcomes between the two groups (P>0.05) except LgBCEA (P=0.046) after 15 sessions. We concluded that the both MBFT frequencies are effective at improving vision and quality of life in patients with maculopathies. The alternate daily training group showed less time-dependent of improvement in all parameters and a greater benefit in fixation stability. Ten sessions are the optimal number of treatment sessions for alternate daily training.
