Abstract

PURPOSE

To describe the relationship between binocular summation and stereoacuity after strabismus surgery.

DESIGN

Prospective case series.

METHODS

setting: Stein Eye Institute, University of California Los Angeles.

PATIENT POPULATION

Pediatric strabismic patients who underwent strabismus surgery between 2010 and 2015.

OBSERVATION PROCEDURES

Early Treatment Diabetic Retinopathy Study visual acuity, Sloan low-contrast acuity (LCA, 2.5% and 1.25%), and Randot stereoacuity 2 months following surgical correction of strabismus.

MAIN OUTCOME MEASURES

The relationship between binocular summation (BiS), calculated as the difference between the binocular visual acuity score and that of the better eye, and stereoacuity.

RESULTS

A total of 130 postoperative strabismic patients were studied. The relationship between binocular summation and stereoacuity was studied by Spearman correlation. There were significant correlations between BiS for 2.5% LCA with near and distance stereoacuity (P = .006 and P = .009). BiS for 1.25% LCA was also significantly correlated with near stereoacuity (P = .04). Near stereoacuity and BiS for 2.5% and 1.25% LCA were significantly dependent (Pearson χ(2), P = .006 and P = .026). Patients with stereoacuity demonstrated significantly more BiS in 2.5% LCA of 2.7 (P = .022) and 3.1 (P = .014) letters than did those without near or distance stereoacuity, respectively.

CONCLUSIONS

These findings demonstrate that stereopsis and binocular summation are significantly correlated in patients who have undergone surgical correction of strabismus.

摘要

目的

描述斜视手术后双眼总和与立体视锐度之间的关系。

设计

前瞻性病例系列研究。

方法

地点：加利福尼亚大学洛杉矶分校斯坦因眼科研究所。

研究对象

2010年至2015年间接受斜视手术的小儿斜视患者。

观察程序

斜视手术矫正后2个月时的糖尿病视网膜病变早期治疗研究视力、斯隆低对比度视力（LCA，2.5%和1.25%）以及兰多立体视锐度。

主要观察指标

双眼总和（BiS），计算方法为双眼视力得分与较好眼视力得分之差，与立体视锐度之间的关系。

结果

共研究了130例斜视手术后患者。采用Spearman相关性分析双眼总和与立体视锐度之间的关系。2.5%LCA的BiS与近立体视锐度和远立体视锐度之间存在显著相关性（P = 0.006和P = 0.009）。1.25%LCA的BiS与近立体视锐度也显著相关（P = 0.04）。2.5%和1.25%LCA的近立体视锐度与BiS显著相关（Pearson χ(2)，P = 0.006和P = 0.026）。有立体视锐度的患者在2.5%LCA中分别比无近或远立体视锐度的患者表现出多2.7（P = 0.022）和3.1（P = 0.014）个字母的BiS。
