■研究收敛功能不全型间歇性外斜视(CI型X(T))立体视力差的特征和危险因素。
■观测,横断面研究。
■从2018年1月至2022年1月,纳入了615CIX型(T)和222基本型间歇性外斜视(X(T))的病历。比较了两种类型的特征,使用logistic回归分析了临床因素与不良立体视力之间的关联。
■与基本类型X(T)相比,手术年龄较早,更短的未对准持续时间,在CI型X(T)中观察到较小的距离外偏差。与基本X型(T)相比,CIX型(T)表现出更好的感觉状态和较低的眼部肌肉功能障碍发生率。手术年龄在6至12岁之间(比值比[OR],0.595;与≤6年相比)与差的近立体视敏度呈负相关,而持续时间超过4年(或,2.474),弱视(或,4.057),大距离外偏差(>60PD:或,2.462)和屈光参差(>2.00D:或,3.874)与差的近立体视敏度呈正相关。发病年龄大于6岁(6-9岁:OR,0.397;>9年:或,0.317)与更好的距离立体敏锐度相关,而大距离外偏差(>60PD:或,23.513),优势眼最佳矫正视力(BCVA)比0.20(OR,2.987)与较差的距离立体敏锐度呈正相关。
■CI型X(T)早期拒绝手术,具有小的距离外偏差,更好的感官状态,眼肌肉功能障碍的发生率低。早期发病年龄之间有很强的剂量依赖性联系,长错位持续时间,更坏的优势眼BCVA,距离偏离,弱视,屈光参差,并证实了较差的立体敏锐度。
UNASSIGNED: To investigate characteristics and risk factors of poor
stereoacuity of Convergence insufficiency-type Intermittent Exotropia (CI-type X(T)).
UNASSIGNED: Observational, cross-sectional study.
UNASSIGNED: The medical records of 615 CI-type X(T) and 222 basic-type intermittent exotropia (X(T)) were enrolled from January 2018 to January 2022. The characteristics were compared between the two types, and the associations between clinical factors and poor
stereoacuity were examined using logistic regression.
UNASSIGNED: Compared with basic-type X(T), earlier surgery age, shorter misalignment duration, and the smaller distance exodeviation were observed in CI-type X(T). The CI-type X(T) demonstrated better sensory status and lower incidence of ocular muscle dysfunction than did the basic-type X(T). The surgery age between 6 and 12 years (odds ratio [OR], 0.595; compared with ≤6 years) was inversely associated with poor near
stereoacuity, whereas duration more than 4 years (OR, 2.474), amblyopia (OR, 4.057), large distance exodeviation (>60PD: OR, 2.462) and anisometropia (>2.00D: OR, 3.874) were positively associated with poor near
stereoacuity. The onset age older than 6 years (6-9 years: OR, 0.397; >9 years: OR, 0.317) was associated with better distance
stereoacuity, whereas large distance exodeviation (>60PD: OR, 23.513), and dominant eye best corrected visual acuity (BCVA) worsen than 0.20 (OR, 2.987) were positively associated with poor distance stereoacuity.
UNASSIGNED: CI-type X(T) declined surgery early, with small distance exodeviation, better sensory status, and low incidence of ocular muscle dysfunction. A strong dose-dependent link between early onset age, long misalignment duration, worse dominant eye BCVA, distance exodeviation, amblyopia, anisometropia, and poor stereoacuity was confirmed.
