This study aims to determine if ocular dominance plays a role in predicting compensatory eyebrow elevation in cases of ptosis.
This retrospective observational cohort study screened all individuals presenting to two tertiary oculoplastics practices with complaints of ptosis for entry. Primary position photographs were obtained. Ocular dominance was assessed via a modified Porta test. Ptosis was defined in bilateral cases as marginal reflex distance of <2.5 mm in both eyes and in unilateral cases as either an MRD1 < 2.5 mm or MRD1 of >1 mm lower on one side. Asymmetry in brow height was defined as a difference of >1 mm. Chi square and t-tests were performed.
Sixty-eight patients from the both tertiary practices met inclusion criteria (37 male, 31 female). Concordance between the higher brow and the dominant side was 50.0% (n = 22, p > 0.05). Mean brow height on the dominant side (15.5 mm) was not statistically different than brow height on the non-dominant side (15.3 mm, p > 0.05). The concordance between the higher brow and the lower MRD1 eyelid was not significant (45.5%, n = 20, p > 0.05). The difference in mean brow height between the lower and higher MRD1 eyes was not significantly different (-0.11 mm; p > 0.05). This also held true when restricted to unilateral cases (0.28; p > 0.05).
Although asymmetric brow elevation can be noted in patients with ptosis, ocular dominance does not appear to be concordant with this asymmetry. Additionally, brow height does not appear to be concordant with MRD1 in cases of ptosis.
本研究旨在确定眼优势是否在预测上睑下垂患者的代偿性眉上抬中起作用。
这项回顾性观察队列研究筛选了所有因上睑下垂主诉就诊于两家三级眼整形科的个体。获取原在位照片。通过改良的波尔塔试验评估眼优势。双侧上睑下垂定义为双眼边缘反射距离均<2.5mm，单侧上睑下垂定义为一侧MRD1<2.5mm或MRD1比另一侧低>1mm。眉高不对称定义为差值>1mm。进行卡方检验和t检验。
两家三级医疗机构的68例患者符合纳入标准（男性37例，女性31例）。较高眉毛与优势侧的一致性为50.0%（n = 22，p>0.05）。优势侧的平均眉高（15.5mm）与非优势侧的眉高（15.3mm，p>0.05）无统计学差异。较高眉毛与较低MRD1眼睑之间的一致性不显著（45.5%，n = 20，p>0.05）。较低和较高MRD1眼之间的平均眉高差异无统计学意义（-0.11mm；p>0.05）。在仅纳入单侧病例时也是如此（0.28；p>0.05）。
虽然上睑下垂患者可出现不对称眉上抬，但眼优势似乎与这种不对称不一致。此外，在上睑下垂病例中，眉高似乎与MRD1不一致。
