Effect of multimedia training system on amblyopia in children of different ages and types

Abstract

Objective To explore the effect of multimedia training on amblyopia in children of different ages and types. Methods From March 2014 to April 2017, the clinical data of 128 amblyopia children with multimedia visual training in the ophthalmology outpatient department of Jincheng Ophthalmology Hospital were analyzed retrospectively. The therapeutic effects of different age groups, different amblyopia types and different amblyopia children were analyzed. Results The total effective rates of the 3-5 years old group, >5-8 years old group and >8-12 years old group were 73.17%, 95.45% and 52.38%, respectively. The total effective rate of the >5-8 years old group was significantly higher than that of the 3-5 years old group and >8-12 years old group, the differences was statistically significant (χ2=6.623, 19.423, all P 8-12 years old group (χ2=6.387, P<0.05). The total effective rates of the ametropia group, anisometropic group and strabismus group were 92.06%, 70.00% and 68.00%, respectively. The total effective rate of the ametropia group was higher than that of the anisometropia group and strabismus group, the difference was statistically significant (χ2=8.643, 8.231, all P<0.05). The total effective rates of the central fixation group and side center gaze group were 86.17% and 67.65%, respectively, and the difference between the two groups was statistically significant (χ2=5.623, P<0.05). The total effective rates of the mild amblyopia group, the moderate amblyopia group and the severe amblyopia group were 98.15%, 75.81% and 0.00%, respectively, the difference among the three groups was statistically significant (χ2=12.116, 56.795, all P<0.05). Conclusion The effect of multimedia visual training on children with small age, light refraction, ametropia and central gaze is significant, but the effect is not good for older, severe amblyopia, anisometropia and parametropic amblyopia.
