Abstract:AIM: To observe and analyze the therapeutic effect of fine training combined with virtual reality brain vision training in amblyopic children.
METHODS: Case control study. 232 cases(416 eyes)of amblyopia were diagnosed in Baoding children's Hospital for the first time. They were randomly divided into two groups. Group A was treated with fine training, while group B was treated with fine training combined with visual training. Duration of treatment was 6mo. The patients were followed up for 6mo. Objective to observe the clinical efficacy of amblyopia in children of different ages and degrees.
RESULTS: The total basic cure rate was 35.6%(74/208)in group A and 51.4%(107/208)in group B, which was higher than that in group A(P<0.01). The total effective rate was 80.8%(168/208)in group A, 91.3%(190/208)in group B, which was higher than that in group A(P=0.006). Therapeutic effect of each age group: the basic cure rates of group A were 55.9%(38/68), 34.9%(30/86), 11.1%(6/54)(rs=-0.76, P<0.01), respectively. The basic cure rates of group B were 70.6%(48/68), 54.6%(47/86), 22.2%(12/54)(rs=-0.78, P<0.01), respectively. The basic cure rate of group A and group B decreased with age. The effective rates of group A were 100%(68/68), 81.4%(70/86), 55.6%(30/54)(rs=-0.67, P<0.01), respectively. The effective rates of group B were 100%(68/68), 93.0%(80/86), 77.8%(42/54)(rs=-0.64, P<0.01), respectively. The efficiencies of A and B groups decreased with age. Therapeutic effect of amblyopia degree groups: the basic cure rates of group A were 63.3%(50/79), 25.0%(22/88)and 4.9%(2/41)(rs=-0.93, P<0.01), respectively. The basic cure rates of group B were 81.0%(64/79), 44.3%(39/88)and 9.8%(4/41),respectively(rs=-0.89, P<0.01). The basic cure rate of groups A and B was negatively correlated with the degree of amblyopia. The effective rates of group A were 83.5%(66/79), 79.5%(70/88), 78.0%(32/41)(rs=0.00, P=12.316), respectively. The effective rates of group B were 91.1%(72/79), 89.8%(79/88), 95.1%(39/41)(rs=0.00, P=15.603), respectively. There was no significant correlation between amblyopia severity and efficiency in groups A and B.
CONCLUSION: Fine training combined with virtual reality brain vision training is a safe and effective way to treat amblyopia. There is a certain correlation between the clinical efficacy and the age and the degree of amblyopia.
