■评估先天性单侧上斜肌麻痹(SOP)患者在不同视线下的偏离角度与头部倾斜量之间的相关性。
■该病例系列研究是对20例连续头部倾斜的SOP患者进行的。基于Bielschowsky三步测试,偏差角度是在不同的视线下测量的。此外,计算了两个侧向凝视(凝视差)和两个头部倾斜侧(双侧头部倾斜差)之间的高斜视差。对于测量头倾斜,通过CorelDrawX7软件捕获并分析来自40厘米的习惯性异常头部位置的特写照片。
■患者的平均年龄为13±9岁(范围,2.5-31年)。同侧和对侧头部倾斜的高斜视平均角度为24.5Δ±7.1Δ和6.5Δ±4.2Δ,分别为(P<0.001),在同侧和对侧横向凝视位置,它是8.2Δ±5.5Δ和22.5Δ±6.1Δ,分别(P<0.001)。双侧头倾斜性高斜视差异的平均值为18Δ±5.3Δ,注视性高斜视差异为14.3Δ±6.16Δ。双侧头倾斜性斜视差值与头倾斜量呈正相关(R=0.609,R2=0.371,P=0.004,头倾斜量=0.39×[双侧头倾斜性斜视差值]+1.77)。头部倾斜量与注视上斜视差也呈正相关(R=0.492,R2=0.242,P=0.028,头部倾斜量=0.27×[注视上斜视差]+4.81)。
■在SOP患者中,头部倾斜量与双侧头部倾斜上斜视差和注视上斜视差呈正相关。
UNASSIGNED: To evaluate the correlation between the angle of deviation in different gazes and the amount of head tilt in patients with congenital unilateral superior oblique muscle palsy (SOP).
UNASSIGNED: This case series study was performed on 20 consecutive SOP patients with head tilt. Based on the Bielschowsky three-step test, the angle of deviation was measured in different gazes. Furthermore, the
hypertropia difference between the two lateral gazes (gaze difference) and the two head tilt sides (bilateral head tilt difference) was calculated. For measuring head tilt, close-up pictures from 40 cm with a habitual abnormal head position were captured and analyzed by the Corel Draw X7 software.
UNASSIGNED: The mean age of patients was 13 ± 9 years (range, 2.5-31 years). The mean angle of
hypertropia in ipsilateral and contralateral head tilt was 24.5 Δ ± 7.1 Δ and 6.5 Δ ± 4.2 Δ, respectively (P < 0.001), and in ipsilateral and contralateral lateral gaze positions, it was 8.2 Δ ± 5.5 Δ and 22.5 Δ ± 6.1 Δ, respectively (P < 0.001). The mean of bilateral head tilt
hypertropia difference was 18 Δ ± 5.3 Δ and gaze
hypertropia difference was 14.3 Δ ± 6.16 Δ. There was a positive correlation between bilateral head tilt hypertropia difference and the amount of head tilt (R = 0.609, R 2 = 0.371, P = 0.004, the amount of head tilt = 0.39 × [Bilateral head tilt hypertropia difference] +1.77). The amount of head tilt also had a positive correlation with the gaze hypertropia difference (R = 0.492, R 2 = 0.242, P = 0.028, the amount of head tilt = 0.27 × [gaze
hypertropia difference] +4.81).
UNASSIGNED: In SOP patients, the amount of head tilt had a positive correlation with bilateral head tilt hypertropia difference and also gaze
hypertropia difference.
