【摘要】 目的观察间歇性外斜视矫正术后双眼单视功能的临床恢复规律。方法对50例间歇性外斜视患者术前术后的双眼单视功能进行测定并分析比较。结果(1)50例患者斜视度25Δ～100Δ,术后近期正位48例。(2)术前具有不同程度的近立体视患者22例(占44％),术后增至47例(占94％)。术前具有远立体视的患者4例,术后增至18例。术后具有远、近立体视功能患者人数显著上升(P<0．05)。(3)术前同视机法具有Ⅰ级功能者22例,术后44例,术后Ⅰ级功能恢复的患者人数显著增多(P<0．05)。(4)术前同视机法测到Ⅱ级功能的患者10例,术后上升到44例。术后Ⅱ级功能的患者比例显著上升(P<0．05)。结论对间歇性外斜视患者提倡早期手术治疗以期改善和恢复立体视功能。更多还原

【Abstract】 Objective To study the recovery rule of binocular visual function in intermittent exouopia after surgical correction. Methods The binocular visual function were determined and analysed with 50 cases of intermittent exotropia before and after surgery. Results (1)there were 25Δ-100Δdegree strabismus in 50 cases and 48 cases obtained normal eye position after surgical correction. (2)47 cases obtained near-steroacuity and 18 cases obtained distance-steroacuity in 50 cases after surgery were all better than 22 cases in near-steroacuity and 18 cases obtained distance-steroacuity before operation. (p<0.05). (4)44 cases of postoperative synoptophoreⅡdegree function were better than 10 cases of preoperative synoptophoreⅡdegree function. (p<0.05). Conclusion The surgical correction should be performed early to improve stereopsis.更多还原
