To determine the types of blepharoptosis and demographics of patients referred to the ophthalmology clinic of the University of Benin Teaching Hospital, thereby providing data on the common types of blepharoptosis within an indigenous Nigerian population.
A hospital-based retrospective chart review of all patients who presented with blepharoptosis from March 2015 to June 2019. Data on age, gender, affected eye, severity and aetiology of blepharoptosis was obtained.
A total of 70 patients met the inclusion criteria for this study. There were 31 males, with a male to female ratio of 1:1.25. The mean age at presentation was 27.5±24.1 years (age range 3 months to 87 years). Fifty-seven (81.4%) patients had unilateral ptosis with left eye involvement in 32 (45.7%). Congenital ptosis was seen in 15 (21.4%) of the cases while acquired ptosis was seen in 55 (78.6%). Neurogenic ptosis had the highest frequency among the mechanistic types of ptosis in 23 (32.9%) patients followed by mechanical 18 (25.7%), myogenic 16 (22.9%) and aponeurotic 13(18.5%). Aponeurotic ptosis occurred more in those older than 50years of age. The association between gender and type of ptosis was not statistically significant. Patients with neurogenic ptosis had more of severe ptosis.
In this study, acquired ptosis was commoner than congenital ptosis. Neurogenic ptosis was the most predominant mechanistic type and tended to be more severe while aponeurotic ptosis was more in those above 50 years of age.
确定转诊至贝宁大学教学医院眼科诊所的眼睑下垂患者的类型和人口统计学特征，从而提供尼日利亚本土人群中常见的眼睑下垂类型数据。
对 2015 年 3 月至 2019 年 6 月期间因眼睑下垂就诊于该医院的所有患者进行基于医院的回顾性图表审查。获取患者的年龄、性别、受累眼、眼睑下垂的严重程度和病因等数据。
共有 70 名患者符合本研究的纳入标准。其中男性 31 例，男女比例为 1:1.25。就诊时的平均年龄为 27.5±24.1 岁（年龄范围为 3 个月至 87 岁）。57 例（81.4%）患者为单侧上睑下垂，其中左侧受累 32 例（45.7%）。先天性上睑下垂 15 例（21.4%），获得性上睑下垂 55 例（78.6%）。神经源性上睑下垂在机械性上睑下垂中发生率最高，为 23 例（32.9%），其次是机械性 18 例（25.7%）、肌源性 16 例（22.9%）和腱膜性 13 例（18.5%）。腱膜性上睑下垂多见于 50 岁以上患者。性别与上睑下垂类型之间无统计学关联。神经源性上睑下垂患者的上睑下垂程度更严重。
在本研究中，获得性上睑下垂比先天性上睑下垂更为常见。神经源性上睑下垂是最常见的机械性类型，且往往更严重，而腱膜性上睑下垂多见于 50 岁以上患者。
