Objective:To evaluate the application effect of a wearable visual field meter based on extended reality (XR) glasses for patients with macular disease.Methods:A self-controlled study was conducted.A total of 41 consecutive patients (41 eyes) with macular disease were recruited at Renmin Hospital of Wuhan University from October 2022 to October 2024.All patients underwent 10-2 center visual field test using a self-developed wearable visual field meter (XRVF), and the results were compared with those obtained using a traditional Humphrey field analyzer (HFA).The comparison parameters included mean retinal sensitivity (MS), false positive rate (FPR), false negative rate (FNR), and testing duration.A subject satisfaction questionnaire was administered.This study followed the Declaration of Helsinki.The study protocol was approved by the Medical Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2024-K263), and all subjects signed the informed consent form.Results:The retinal sensitivity of patients measured by HFA was (23.24±3.71)dB, which was higher than (22.01±3.45)dB by XRVF, showing a statistically significant difference ( t=4.924, P=0.036).The FPR measured by HFA and XRVF were (2.39±2.51)% and (2.59±3.29)%, respectively, and the FNR were (3.49±6.05)% and (3.74±5.38)%, respectively, showing no statistically significant difference ( t=-3.624, P=0.948; t=-1.241, P=0.519).The median test duration for HFA and XRVF was 6.15 (5.78, 6.65) and 5.98 (5.71, 6.69)minutes, respectively, without statistically significant difference ( Z=-1.987, P=0.953).92.6% of the subjects thought the device was comfortable, simple and practical. Conclusions:The XRVF has good consistency with the HFA, can effectively and reliably evaluate the visual field function of patients with macular disease, and is easily accepted by patients.

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.
