“…In accordance with the literature, our results also highlight the positive effects of biofeedback on the functional abilities of people with vision impairments. The results of our study confirm the findings of other authors, reporting fixation stability and reading speed as a daily living visual task and improvement for visually impaired subjects with central field loss 18 …”

“…The majority of the current techniques involve the use of biofeedback, and one of the most used tools in this area, which supports this rehabilitation method, is the microperimeter. [16][17][18] The microperimeter, in particular MP-3 (Nidek Technologies, Padua, Italy), which consists of a fundus camera and a dedicated personal computer with a specific operating system for the acquisition, analysis, and processing of data, allows structured photo stimulation through biofeedback, dynamic and real-time visualization of the retina to be examined, execution of functional tests of the differential threshold of retinal sensitivity, fixation tests, and retinography. This study aimed to evaluate the effects of two different MP-3 biofeedback strategies on the visual performance of subjects with central vision loss.…”

Significance This investigation reports for the first time the effects of different microperimetric biofeedback strategies in visually impaired subjects with central field loss. Purpose To evaluate the effects of two MP-3 micro-perimeter biofeedback strategies on the visual performance of subjects with central vision loss. Moreover, changes between the groups were compared to provide indications of practice with biofeedback stimulation in subjects with central vision loss. Methods Using simple randomization, 19 participants were trained according to two different biofeedback stimulation approaches using the MP-3 microperimeter. Patients were assigned to two different groups: subjects trained for 2 days a week (Group A) and 3 days a week (Group B). The patients in each group were randomized to perform a total of 10 or 15 sessions. Results Fixation stability increased from 4.5°2 (± 2.8) to 2.3°2 (± 2.2) and from 8.2°2 (± 6.9) to 1.4°2 (± 1) after 2 and 3 weekly biofeedback training sessions, respectively (P < .05). Biofeedback training induced a significant improvement of 40.7% and 29.4% in reading speed for groups A and B, respectively (P < .05). A comparison of two weekly biofeedback training sessions with three weekly biofeedback sessions demonstrated greater fixation stability in Group B (P < .05). Conclusions This study conclude that a biofeedback intervention is effective in enhancing oculomotor control in patients with central vision loss. In our study, a more intensive biofeedback strategy seemed to produce significantly better results in terms of functional vision parameters.

BackgroundHomonymous hemianopsia (HH) corresponds to vision loss in one hemi-field secondary to retro-chiasmal injury. Patients with HH experience difficulties in scanning and orientation in their environment. Near vision daily activities such as reading can also be impaired. There is an unmet need for standardized vision rehabilitation protocols for HH. We investigated the effectiveness of biofeedback training (BT), used for vision rehabilitation in patients with central vision loss, in individuals with HH.MethodsIn this prospective pilot pre/post study, 12 participants, with HH consecutive to brain injury, performed 5 weekly BT sessions for 20 min each under supervision using the Macular Integrity Assessment microperimeter. BT consisted of relocation of the retinal locus 1–4° toward the blind hemi-field. Outcomes measured post-BT were paracentral retinal sensitivity, visual acuity (near vision), fixation stability, contrast sensitivity, reading speed, and visual functioning questionnaire. Statistical analysis was performed using Bayesian paired t-tests.ResultsParacentral retinal sensitivity significantly increased by 2.7 ± 0.9 dB in the treated eye in 9/11 of the participants. Significant improvements with medium-to-large effect size were observed for fixation stability (8/12 participants), contrast sensitivity (6/12 participants) and near vision visual acuity (10/12 participants). Reading speed increased by 32.5 ± 32.4 words per minute in 10/11 participants. Quality of vision scores improved significantly with large effect size for visual ability, visual information and mobility.ConclusionBT led to encouraging improvements in visual functions and functional vision in individuals with HH. Further confirmation with larger trials is required.

“…Several studies have researched the bene ts of MBFT and showed promising results. [11][12][13][14] To date, standard practice consensus regarding the required frequency and number of sessions is not applicable. Therefore, this study aimed to examine the impact of microperimetric biofeedback training on visual acuity, near vision acuity, xation stability, and reading rate in patients with AMD.…”

Background Age-related macular degeneration (AMD) is a degenerative disease affecting retinal tissue that may cause central vision loss. Microperimetric Biofeedback Training (MBFT) is a visual rehabilitation to train patients who have lost foveal fixation to relocate the locus to an area of the retina with better sensitivity. Objective To determine the impact of MBFT on the quality of vision in patients with AMD. Methods This study was a prospective, interventional, comparative study with subjects of patients diagnosed with AMD in the National Eye Center Cicendo Eye Hospital. Patients were randomly divided into two groups, intervention and non-intervention, with balance block randomization. The intervention group would receive six MBFT training sessions of 10-minute time duration each. Results The number of subjects enrolled in this study was 36, with 18 patients in each group. A statistically significant improvement of best corrected visual acuity (BCVA) was found after the intervention, from 1.24 ± 0.416 logMar to 0.83 ± 0.242 (P < 0.001). A statistically significant improvement for near vision acuity (NVA) was also observed, from 1.02 ± 0.307 logMar to 0.69 ± 0.278 logMar (P < 0.001). In addition, reading rate increased, from 40.83 ± 30,411 words/minute to 65.06 ± 31,598 words/minute (P < 0.001). Similarly, a comparison of changes in BCVA, NVA, and reading rate between intervention and non-intervention groups showed a significant difference (P < 0.001). Conclusion Microperimetric biofeedback training significantly and positively impacts visual acuity, near vision acuity, and reading rate in patients with AMD.
