Abstract：Objective:To analyze the comparative study of reading ability in patients with low vision based on different mnemonic methods.Methods:50 patients who had experienced and fitted with typoscope(including patients fitted with optical or electronic typoscope)were selected as research objects from the low vision outpatient department of the hospital from December 2017 to December 2022.They were divided into 4 groups according to different methods of visual aid.Group 1 only used optical typoscope.Group 2 used visual training and electronic typoscope.Group 3 only used electronic typoscope.Group 4 were combined with visual training and optical typoscope to test the reading ability of 50 patients,including reading speed,reading accuracy,reading duration and reading comfort.The best corrected vision,quality of life score and satisfaction of vision correction after training were compared between the four groups.Results:Compared with group 1,group 3 and group 4,group 2 had higher reading speed,higher reading accuracy,longer reading duration,higher reading comfort score,and better improvement effect of best corrected vision after training,with statistically significant difference(x2=21.621,12.629,28.063,121.627,14.044;P＜0.05).After training,far visual acuity,adjusted visual acuity,reading and fine work,daily living ability score and satisfaction of visual acuity correction in group 2 were significantly higher than those in group 1,group 3 and group 4,with statistically significant difference(F=0.642,25.364,18.962,16.547,x2=16.576;P＜0.05).Conclusion:The implementation of electronic visual AIDS for visual training of patients with low vision can improve the reading accuracy of patients with low vision,improve the quality of life,and ensure the comfort of reading.It has high practical value.
