The purpose of this study was to compare ocular complications and efficacy of preseptal (PST) versus those of pretarsal (PTS) botulinum toxin type A (BoNT-A) therapy in cases of benign essential blepharospasm (BEB).
Randomized clinical trial.
Setting: university hospital.
24 participants with BEB were enrolled from August 2019 to June 2020. All patients and the outcome evaluator were masked to the injection allocation.
for each participant, 1 eye was randomized to receive PST BoNT-A injection, and the fellow eye received PTS BoNT-A injection of the same amount from a single investigator. At baseline, 1, and 3 months after the injection, we collected the symptoms of tearing, lagophthalmos, ptosis, and diplopia and measured margin-to-reflex distance (MRD) 1 and 2 (mm), degree of lagophthalmos (mm), presence of ectropion, entropion, limitation of ocular motility, tear film breakup time (second), Schirmer's test (mm) , ocular surface staining scores (Oxford's scheme), and Jankovic rating scale of both eyes separately. Main outcome measurements were complications of the injection.
There were statistically significant higher rates of self-reported lagophthalmos in PTS (n = 12; 52.17%) than in PST (n = 7; 30.43%) BoNT-A injections (P = .024) and significantly higher estimated measurements of lagophthalmos in PTS (0.59 mm; 95% confidence interval [CI]: 0.44-0.72) than in PST (0.26 mm; 95% CI: 0.12-0.40) injection at 1 month using an interaction model (Bonferroni-corrected P = .001). No significant differences in the efficacy and other complication outcomes between the injection locations were observed.
PTS BoNT-A injection had a higher rate of lagophthalmos than PST BoNT-A injection for BEB.
本研究旨在比较睑前(PST)与睑板前(PTS)A型肉毒杆菌毒素(BoNT-A)治疗在良性特发性眼睑痉挛(BEB)患者中的眼部并发症及疗效。
随机临床试验。
地点:大学医院。
2019年8月至2020年6月招募了24例BEB患者。所有患者及结果评估者均对注射分配情况不知情。
对每位参与者,一只眼睛随机接受睑前BoNT-A注射,另一只眼睛由同一位研究者注射等量的睑板前BoNT-A。在基线、注射后1个月和3个月时,我们分别收集流泪、兔眼、上睑下垂和复视症状,并测量双眼的边缘至反射距离(MRD)1和2(mm)、兔眼程度(mm)、睑外翻、睑内翻、眼球运动受限情况、泪膜破裂时间(秒)、泪液分泌试验(mm)、眼表染色评分(牛津方案)以及扬科维奇评分量表。主要结局指标为注射并发症。
PTS(n = 12;52.17%)注射BoNT-A后自我报告的兔眼发生率在统计学上显著高于PST(n = 7;30.43%)注射(P = 0.024),并且在1个月时,使用交互模型(经邦费罗尼校正的P = 0.001),PTS注射的兔眼估计测量值(0.59 mm;95%置信区间[CI]:0.44 - 0.72)显著高于PST注射(0.26 mm;95% CI:0.12 - 0.40)。在注射部位之间,未观察到疗效及其他并发症结果的显著差异。
对于BEB,PTS注射BoNT-A比PST注射BoNT-A导致兔眼的发生率更高。
