摘要
目的探讨间歇性外斜视患者远距离立体视的临床特点及其相关影响因素,为手术时机的选择提供参考依据。方法利用Optec 3500视觉检查仪检查61例间歇性外斜视患者的远距离立体视。采用Titmus立体图检查近距离立体视。结果①术前远距离立体视丧失的比例和视锐度损伤的程度均明显高于近距离立体视。②术后远距离立体视重建的比例提高和立体视锐度改善显著。③术后患者的远距离立体视与病程呈正相关。结论①患者术前远距离立体视大部分丧失,近距离立体视保持较好。②手术矫正可明显提高患者的远距离立体视,主要影响因素为病程。③远距离立体视锐度可作为选择手术时机的一个重要参考依据。
Objective To stndy the clinical characters and the related factors affecting the stereoacuity of the intermittent exotropic patients before and after strabismus surgery in order to provide the referenee for the. surgery indicatiorns. Methods Optech 3500 vision tester was used to examine, the. distance stereoacuity among 61 intermittent exotropic patieants. The near stereoacuity eaamination was taken by using Titmns block diagram. Results ①The distance stereoacuity and the visual sensitivlty in preoperative intexmittent exotropic patients were obviously worse, than that of near stereoacuity. ② The. distanee stereoacuity were significantly improved by operation. ③The postoperative effect of patients＇ distance. sterenaculity was positive correlation with the disease, course.. Conclusion Most of intermfittent exotropic patients lost their distance, stereoacuity but they could maintain relatively good near stereoacuity. The operation can obviously restore or improve the. patient＇ s distance stereoacuity, and the. main affecting factor was age for operation. Distahoe stereoacuity should be an important referential indication of surgery for restoring the binocular vision after surgery.
