47例4～15岁儿童微小斜视性弱视是从常规遮盖治疗的单眼弱视效果不好的患者中筛选的。双眼单视时,中心抑制性暗点的存在是诊断本病的要点。比较四种检查暗点的方法,以4~Δ棱镜移位试验法阳性率高,且设备简单、操作容易而快速,优于其他三种方法,是筛选儿童弱视的一种理想手段。应用棱镜检查,本组病例的微小斜视的水平范围在2~Δ～12~Δ,平均5.7~Δ±3.6~Δ。采用同视机闪烁脱抑制消除暗点加遮盖法治疗弱视,治愈率为53.2%,治疗有效率为77%。影响预后的关键问题是暗点的抑制程度及时间,因此早期脱抑制治疗,尤其早期矫正屈光参差是治疗和预防这类弱视的关键环节。 Forty fourteen to fifteen years old children with strabismic amblyopia were screened from patients with unilateral monocular amblyopia that were routinely obscured. Binocular single vision, the presence of central inhibitory dark spots is the diagnosis of the disease points. Compared with the four methods of checking dark spots, the method of 4 ~ Δ prism displacement test has the advantages of high positive rate, simple equipment, easy and fast operation, and is superior to the other three methods. It is an ideal method to screen amblyopia in children. Prism examination, the group of patients with micro strabismus in the range of 2 ~ Δ ~ 12 ~ Δ, an average of 5.7 ~ Δ ± 3.6 ~ Δ. The use of the same flicker off inhibition to eliminate dark spots plus cover method for the treatment of amblyopia, the cure rate was 53.2%, the effective rate was 77%. The key issue affecting the prognosis is the degree of inhibition of dark spots and time, so early de-suppression therapy, especially early correction of anisometropia is the key to the treatment and prevention of such amblyopia.
