“…Pattern stimulation is composed by significant recognition shapes that could improve intraretinal integration processes, retina-brain transmission and stimulus recognition. Structured stimuli, together with the acoustic stimuli, could increase the function of PRL, as previously observed [34,35].…”

“…The repeated and persistent training practice of a searching movement toward PRL could result in lasting and consolidate physiological changes in motor neural networks. Another aspect to be considered is the combination of an acoustic tone and a structured light stimulus, which demonstrated better functional recovery on visual acuity, retinal sensitivity, and fixation stability compared to acoustic tone alone performing biofeedback training [34,35]. The audio feedback can help the brain to fix the PRL by increasing the attentional modulation, while the structural stimulus involves visual receptive fields that are highly sensitive to medium spatial frequencies [4,23].…”

“…Moreover, a flickering visual stimulus is useful in the rehabilitation of patients with low vision at the late stage of AMD [34]. Acoustic stimulus combined to a standardized and structured light stimulus to perform biofeedback could seem more effective on retinal sensitivity and fixation stability [34,35]. In only two papers, the training was performed with more sessions per week, followed by a single session at each follow-up time point [30,36].…”

Background: Despite the high closure rate of large macular hole (LMH) after surgery, visual recovery is often worse than expected. Microperimetric biofeedback can improve visual function in macular pathologies. We evaluated the efficacy of biofeedback on macular function after successful inverted flap technique for LMH. Methods: In this prospective comparative study, 26 patients after LMH surgical closure were enrolled. The whole sample was equally divided into two groups. In Group 1 (trained), patients underwent a double cycle of microperimetric biofeedback, using structured light stimulus plus acoustic tone; in Group 2 (control), patients underwent scheduled visits. We analyzed visual acuity, retinal sensitivity at central 12° (macular sensitivity, MS) and 4° (central macular sensitivity, CMS), and fixation stability over twelve months. Results: Visual acuity improved mainly in the trained group, without any significant differences between the groups (p > 0.05). Only after training did MS significantly improve (p = 0.01). CMS more significantly improved in the trained (p < 0.001) than the control group (p < 0.01) (Group 1 vs. 2, p = 0.004). Only in the trained group did fixation significantly improve (3 months, p ≤ 0.03; 12 months, p ≤ 0.01). An equality test on matched data confirmed a greater significant improvement of CMS (p ≤ 0.02) at all follow-up and fixation (p ≤ 0.02) at last follow-up after training. Conclusions: Microperimetric biofeedback consolidates and increases the improvement of retinal sensitivity and fixation gained after successful inverted flap technique.

“…Eyes with eccentric fixation regularly demonstrate unstable FS with associated low vision. However, it has been reported that FS can be improved with oculomotor exercises known as biofeedback fixation training (BFT) [6,[9][10][11][12][13], a task-oriented behavioural therapy, which according to some authors may drive neural plasticity changes in the visual system [11,14]. BFT consists of asking patients to perform ocular movements towards a specific direction, attempting to align a selected retinal locus with a visual target.…”

Purpose Fixation stability (FS) of the preferred retinal locus (PRL) may be improved by biofeedback fixation training (BFT) with microperimetry. Such training can be done on the patient's PRL or in different retinal loci with better functional characteristics. We studied both options and compared the outcomes. Methods Sixty-seven consecutive patients with bilateral central vision loss, poor FS and visual acuity (VA) lower than 0.3 LogMAR were recruited for BFT with microperimeter. Patients were assigned into 2 groups. In group A, BFT was performed on the patient's spontaneous PRL. In group B, PRL was located between 2 adjacent loci with the highest light sensitivity and the lowest distance from the fovea. Two sets of 12 weekly BFT sessions were performed. Primary outcomes were: FS, VA and reading speed. Results Outcomes were statistically significantly better in group B. Mean percentage of FS at therapy end improved from 32 to 35% for group A and from 40 to 55% in group B. Mean VA improved from 1 to 0.86 in group A and from 1 to 0.84 in group B. Reading speed (wpm) improved from 56 to 58 in group A and from 63 to 89 in group B. Conclusions This study describes a reliable methodology of improving eccentric fixation stability using BFT in microperimetry, when the fixation training locus is individualized as the retinal area with best functional characteristics. Further studies are needed to validate its value in a larger scale of patients, at different stages of the disease, and its persistence over time.

“…This improved or stabilized synchronization is one of the proposed neurophysiological mechanisms of restoration of vision. 46 Further, it is possible that both the MP-1 and the Visual Pathfinder influence oculomotor performance in patients with visual impairment, which might be deficient when they attempt to redirect incoming images to the area with the highest retinal sensitivity. In this way, these techniques might improve the performance of the oculomotor system by increasing the number of correct saccade movements.…”

Quality of life in low vision patients is deeply conditioned by their visual ability, and increased rates of depression, domestic injury, and need for caregiver assistance can be expected as a result of low performance. Much effort have been made recently in order to develop new tools and aids for rehabilitation of low vision, and this research has led to better knowledge of visual function and increased the likelihood of new therapies in the future. Modern low vision rehabilitation is the result of recent advances in science and technology, and will soon have an important role in people with vision impairment, numbers of whom are likely to increase, give the increasing age of the population. This review outlines scientific developments in low vision rehabilitation based on a search of the literature, covers the role of digital technology and advances in neurofunctional rehabilitation, and the possibility of restoring vision by use of retinal prostheses and cellular therapy.
