ABSTRACT

AIM: To investigate the efficacy of the first follow-up visit after daily partial or full-day occlusion of the dominant eye in patients with unilateral amblyopia and assess the maximum efficacy produced by different amounts of occlusion.METHODS: A retrospective clinical study was conducted on 135 cases of unilateral amblyopia cured in our hospital's outpatient clinic from January 2020 to December 2021. They were divided into 2h/d occlusion group, 6h/d occlusion group and all-day occlusion group according to the duration of occlusion, with fine sight training of amblyopic eyes. The effect of the first dose(baseline visual acuity-first review visual acuity), cured visual acuity, stereo vision at the first review and cure time of amblyopic eyes were recorded. The factors affecting the first dose effect in patients with unilateral amblyopia were also analyzed.RESULTS: All patients had a baseline visual acuity of 0.4(0.22, 0.52), a first follow-up visual acuity of 0.22(0.15, 0.3), a first-dose effect of 0.1(0.08, 0.18), and a visual acuity of 0(-0.08, 0.05)when amblyopia cured. The first-dose effects were 0.08(0.07, 0.12)for patients in the 2h/d occlusion group, 0.18(0.08, 0.3)for the 6h/d occlusion group, and 0.10(0.08, 0.18)for the all-day occlusion group. The most significant first-dose effect was the 6h/d occlusion group(P<0.05); Analysis of different influencing factors showed that the highest values of the first-dose effect of 6h/d occlusion were in the 3-6 years group, 7-12 years group, female group, strabismic amblyopia group and mild to moderate group(P<0.05); Furthermore, the first dose effect of the 6h/d occlusion was positively correlated with cure time of amblyopic eyes(rs=0.334, P=0.038). At the first follow-up, 21 cases(53.8%)had improved Titmus stereo visual acuity in the 6h/d occlusion group, which was higher than that in the 2h/d and all-day occlusion groups [16 cases(41.0%), 13 cases(22.8%), P<0.017].CONCLUSIONS: For monocular amblyopia, the first-dose effect of 6h/d occlusion treatment was the most significant, and the recovery of stereopsis was the best.

ABSTRACT

AIM:To evaluate the therapeutic effects of the fine sight training with the smartphones and pads on hyperopia amblyopia of children.METHODS:One hundred and twenty children (120 eyes) with hyperopia amblyopia were randomly divided into two groups in this prospective study.All the children in these two groups received the basic treatments of spectacle correction,penalization therapy and amblyopia trainings.The treatments of red-light blinking and grating as well as traditional fine sight training were used for the children in the control group.However,the smartphones and pads were applied instead of the traditional performances for the fine sight training in the experimental group.Best corrected visual acuity of every child was tested for every 3mo,to observe the time for the visual improvement and efficacy.RESULTS:In comparison with the control group,significant shorter time (80.54 ± 30.87d,P< 0.05) for promoted one line of LogMAR visual acuity and average treatment time (15.34±7.24mo,P<0.05) were harvested in the experimental group.The efficacy in the experimental group was significantly higher than that in the control group (Z=-2.37,P=0.02).CONCLUSION:The fine sight training with the smartphones and pads can improve vison faster than traditional methods and decrease the time of therapy in children with hyperopia amblyopia,thus providing a new strategy for the treatment of hyperopia amblyopia.
