“…Furthermore, this visual improvement from the nystagmus dampening can theoretically boost the visual development in early age children, impacting decisively this cohort's prognosis. 27,28 The improvement in distance vision has been maintained after the therapy up to 5 months so far.…”

Purpose: Biofeedback training (BT) was adapted to idiopathic infantile nystagmus syndrome (IINS) cases to enhance visual functions and quality of life (QoL). Methods: 10 patients (age 9 ± 3.2 years) treated with the audio-visual BT module of the MAIA microperimeter (Centervue, Padova, Italy) were assessed in two baseline visits and 1week post-BT (BT 80 min in total). The outcomes were distance and near binocular best corrected visual acuity (BBCVA), fixation stability, reading speed, contrast sensitivity, stereopsis and Children’s Visual Function Questionnaire. One-way repeated measured ANOVA and paired t-tests were used. Results: Distance BBCVA improved from 0.46 ± 0.21 and 0.43 ± 0.18 pre-BT to 0.33 ± 0.2 logMAR post-BT ( F (2,27) = 13.75, p = 0.0002). Post-BT was better than baseline ( p = 0.0001) and pre-BT ( p = 0.001). Near BBCVA improved from 0.23 ± 0.09 and 0.21 ± 0.14 pre-BT to 0.04 ± 0.08 post-BT (F (2,27) = 22.12, p = 0.000014), post-BT was better than baseline ( p = 0.0001) and pre-BT ( p = 0.0006). Stereopsis improved from 283 ± 338″ to 39 ± 32.2″ ( p = 0.04), contrast sensitivity from 0.26 ± 0.17 to 0.08 ± 0.12 log units ( p = 0.01), and reading speed improved from 74.7 ± 51.2 wpm to 104.7 ± 53.6 wpm ( p = 0.0006). Fixation stability improved from 33.6 ± 28.1 to 14.3 ± 10.1 sq. QoL increased from 23.8 ± 2.2 to 26.3 ± 2.3 units ( p = 0.001). Conclusion: BT benefited all visual functions and QoL in this pilot study, heralding a new possibility for Low Vision Rehabilitation in IINS.

Purpose. To develop a new method of amblyopia treatment in children with unstable central and eccentric fixation by centralizing visual fixation and increasing retinal photosensitivity in the macular region using biofeedback. Material and methods. The study included 27 patients (27 eyes) with amblyopia of various origins, aged 5 to 17 (averagely 9.15 ± 3.19 years), who were able to perform training sessions on the MP-3 Nidek microperimeter (Japan). In addition to standard examination, all patients underwent binocular status assessment using a four-point test, macular electroretinography, microperimetry, optical coherence tomography (OCT). The treatment, carried out on the microperimeter using visual (flickering checkerboard pattern) and sound signal biofeedback, consisted of 10—15 sessions, 10—12 minutes each. All patients were examined before treatment cycle, immediately upon the end of the cycle, and also 1 and 3 months after it. Results. Preliminary results showed an increase in best corrected visual acuity (BCVA) from 0.41 ± 0.24 to 0.68 ± 0.27 (33.9 %), the photosensitivity of the retina in the fovea increased from 27.07 ± 3.90 to 29.8 ± 3.3 dB (10 %), fixation density in the central region from 59.80 ± 31.08 to 72.05 ± 34.5 %(20.4 %) with its amplitude decreased by more than two times. After treatment, unstable central fixation changed to stable central fixation in all cases. With eccentric fixation, the fixation point shifted closer to the central region, and fixation characteristics improved in 75 % of cases. The obtained results retained throughout the observation period which lasted up to 3 months. Conclusion. The proposed new treatment method of amblyopia with impaired fixation of various degrees proved to be effective and safe and can be recommended for use in pediatric patients.
