Abstract:
Objective:To evaluate the short-term rehabilitation effect of wearable visual training devices based on extended reality (XR) glasses in patients after macular hole surgery.Methods:A self-controlled study was conducted.Eleven patients with monocular low vision after macular hole surgery were recruited at Renmin Hospital of Wuhan University from October 2022 to March 2024.All patients underwent biofeedback training for 3 months using the independently developed visual rehabilitation training glasses LOOKBON T10.The LogMAR best corrected visual acuity (BCVA), retinal sensitivity, effective fixation rate, fixation stability, reading speed, vertical metamorphopsia (MV), horizontal metamorphopsia (MH), and Chinese version of the visual-related quality of life assessment form (CVRQoL-25) were compared before and after training.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2024-K263).Written informed consent was obtained from each subject.Results:After training, the patients' BCVA, retinal sensitivity, effective fixation rate, fixation stability, and reading speed were 0.69±0.19, (21.61±2.75)db, (92.43±4.06)%, (93.09±4.31)%, and (104.82±21.85) characters/minute, respectively, which were significantly improved compared to 0.85±0.28, (17.71±3.17)db, (31.83±19.05)%, (32.35±19.12)%, and (69.64±20.17) characters/minute before training ( t=5.253, -5.987, -11.561, -12.003, -11.682; all at P<0.001).After training, MV and MH were (0.29±0.20)° and (0.21±0.24)°, respectively, which were significantly reduced compared to pre-training (0.44±0.24)° and (0.43±0.41)° ( t=9.238, 4.068; both at P<0.01).After training, the CVRQoL-25 score was 1 193.18±229.43, which was significantly higher than pre-training 947.73±203.86 ( t=-11.687, P<0.001). Conclusions:The application of wearable visual training equipment based on XR glasses can effectively improve the visual function of patients with poor visual function recovery after macular hole surgery, and enhance their quality of life.
