AIM:To investigate the recovery condition of child amblyopia,and to seek an effective method of preventing the amblyopia recrudescence,pseudomyopia and myopia formation by off glass indicate. METHODS:After follow-up of 3-7 years(every 1-2 months one time),totally 368 cases 678 eyes were analyzed.The vision,eye position,refraction,fundus, fixation property,computer optometry,dynamic examine by small pupil or the pupil optometry by atropine disperses were examined.The indicate of off glass following 4 targets;(1) bare vision≥1.0 in both eyes, following up time was a half year;(2) normal eye position or residual strabismus<5°;(3) hyperopia diopter≤+ 1.00DS;(4) the hyperopia astigmatism≤+ 0.50 DC.If the bare vision≤0.9,the necessary reason should be ascertain and appropriate treatment should be given. RESULTS:Totally 368 cases(678 eyes) amblyopia children underwent the regular treatment(3-7years),205 cases(678 eyes) took off the glasses(53.7%).And in mild amblyopia children(244 eyes) the off glass rate was 70.5%,which was higher than that in the moderate amblyopia children(114 eyes,37.4%) and the severe amblyopia children(6 eyes,22.2%).The off glass rate in ametropia amblyopia(678 eyes)(305 eyes,59.0%),which was similar to that in anisometropia children(29 eyes, 42.0%) and the strabismus children(30 eyes,32.6%). The pure hyperopia children(316 eyes) off glass rate was 62.7%,higher than that in pure astigmatism children(11 eyes,28.2%) and the complex astigmatism children(37 eyes,30.1%);But the pure myopia amblyopia,pure myopia astigmatism amblyopia,and the complex myopia astigmatism amblyopia did not take off the glass.The amblyopia child with the low diopter serve as mild amblyopia(289 eyes,spherical Iens≤3.00D,cylindrical lens≤1.00D) and the off glass rate was 58.7%;The moderate amblyopia(58 eyes,spherical lens 3.25-4.75D, cylindrical lens 1.25-1.50D),accounted for 48.5%,higher than that in high amblyopia(spherical lens≥5.00D, cylindrical lens≥1.75D;17 eyes,25.4%).The off glass rate was 70.5%for 3-8 years.The recurrence rate of amblyopia was in 1.3%,pseudomyopia in 1.5%,myopia in 9.1%,and the residual strbismus in 0.6%.115 cases (229 eyes,33.8%) should be observed. CONCLUSION:Analysis of the recovery in child amblyopia can consolidate curative effect,reduce the recurrence rate,enhance therapeutic effect.The long-term regular tracing and observation of the recovery in child amblyopia can discover the early amblyopia recrudescence and pseudomyopia,and prevent the formation of myopia and enhance the treatment of amblyopia by taking the correct remedial measure promptly.The above 4 items of off glass indicate are feasible;Tracing observation was necessary after 12 years old.
