[Abstract]:Objective: to observe the effects of different types and degrees of amblyopia on stereopsis in patients with amblyopia when corrected visual acuity reaches 1.0. Methods: from October 2014 to December 2016, 247 patients with 1.0 amblyopia, 116 ametropia amblyopia, 84 anisometropia amblyopia, 30 strabismus amblyopia and 17 form deprivation amblyopia were analyzed retrospectively. According to the corrected visual acuity at first visit, it was divided into three groups: mild, moderate and severe. The near stereopsis was measured by Yan Shaoming stereovision. The near stereopsis acuity was divided into three groups: central stereopsis, macular stereopsis and peripheral stereopsis. The number of macular stereopsis, peripheral stereopsis, different types and different degrees of amblyopia were statistically significant in the three groups. According to the existence and non-existence of distant stereopsis, the same vision machine was recorded as positive group (P < 0.01) and negative group (P < 0.01). The number of people in each type and different degree amblyopia group were counted, and there was statistical significance in comparing different types and different degrees of amblyopia far stereoscopic vision. Results the relationship between different types of stereopsis and stereopsis: ametropia amblyopia center had the highest rate of stereopsis acuity. The stereoscopic acuity of anisometropia amblyopia center was 47.61, that of strabismus amblyopia center was 26.67, and that of form deprivation amblyopia center was 29.41. The existence rate of stereopsis acuity around strabismus amblyopia was the highest. Accounting for 33.33, the peripheral stereopsis acuity of form deprivation amblyopia is 29.41, that of anisometropia amblyopia is 15.48, and that of ametropia amblyopia peripheral stereopsis is 8.62.4 kinds of amblyopia near stereopsis have statistical significance. There was no statistical significance between the visual acuity of amblyopia and the relationship between different degrees and stereopsis in different types of amblyopic amblyopia: in the amblyopic amblyopia with mild amblyopia, the central stereopsis acuity of mild amblyopia was the highest, and the visual acuity of the amblyopia center was the highest in all types of amblyopia. The central stereopsis acuity of moderate amblyopia center was 40.00.The stereopsis acuity of severe amblyopia center was 17.24.The stereopsis acuity around severe amblyopia was high. There were significant differences in the degree of peripheral stereopsis between moderate amblyopia and mild amblyopia (18.92.3). There was statistical significance in the comparison of the near stereopsis of amblyopia. There was no statistical significance in the comparison of the degree of stereoscopic acuity between moderate amblyopia and mild amblyopia (P 0.053.024P0.05). In anisometropic amblyopia, the rate of central stereopsis acuity of mild amblyopia was the highest (66.67%), that of moderate amblyopia center was 32.35%, that of severe amblyopia center was 25.00%, that of severe amblyopia peripheral stereopsis was high, that of moderate amblyopia center was 32.35%, and that of severe amblyopia center was 25.00%. There were significant differences in the peripheral stereopsis acuity between moderate amblyopia and mild amblyopia patients (16.67.3 and 16.67.3, respectively). There was no statistical significance between the degree of amblyopia and the near stereopsis of amblyopia. There was no significant difference in the degree of stereopsis between moderate amblyopia and mild amblyopia. Conclusion (1) different types of amblyopia have different effects on near stereopsis, but there is no obvious difference in far stereopsis. The amblyopia of ametropia amblyopia is the best, followed by anisometropia amblyopia and strabismus amblyopia. The less degree of amblyopia, the better the recovery of near stereopsis.
