Survey on vision-related quality of life for visual impairment students in special school / 中国康复理论与实践

ABSTRACT

@#Objective To investigate visual impairment students' quality of life and its influencing factors in Braille learning class at Quanzhou Special School. Methods November, 2020, 52 students (aged seven to 26) with the best corrected distance visual acuity of the better eye above 0.02 were investigated with near visual acuity, contrast sensitivity and Chinese-version Low Vision Quality of Life Questionnaire (CLVQOL). The subjects were divided into second grade blindness group, first grade low vision group and second grade low vision group according to the best corrected distance visual acuity of the better eye. Results There were significant differences in distance visual acuity (Z = 45.671, P < 0.001), near visual acuity (Z = 24.972, P < 0.001), and contrast sensitivity (CS) ( Z = 13.285, P = 0.001) among three groups. There was a correlation between near visual acuity and distance visual acuity (r = 0.74, P < 0.001), CS to distance visual acuity (r = -0.58, P < 0.001) and near visual acuity (r = -0.57, P < 0.001), score of CLVQOL and CS (r = 0.44, P < 0.001). There were significant differences in the total score (Z = 10.145, P = 0.006), distance visual acuity subscale (Z = 13.586, P = 0.001), psychological adjustment subscale (Z = 7.824, P = 0.020), reading and fine work subscale (Z = 7.923, P = 0.019) of CLVQOL among the three groups. Conclusion Quality of life is different with the visual impairment for students in special school, especially the distance visual acuity, psychological adjustment and fine reading. CS correlates to the quality of life of visually impaired students, which needs to be a part of evaluation of visual function.
