The clinical picture of blepharoptosis varies from a cosmetic problem to severe visual dysfunction depending on the pathogenesis and the degree of ptosis.
To study the type, pattern and causes of ptosis in patients seeking oculopastic care in western Terai of Nepal Patients and methods: A retrospective descriptive hospital based was carried out over a period of 2 years in oculoplastic clinic in Lumbini Eye Institute, Bhairahawa. Demographic variables including the age of the patient, gender, laterality of the eye(s), visual acuity, presence of refractive error and or amblyopia, type of ptosis and previous ptosis surgery were recorded.
There were altogether 326 patients of ptosis during the 2 year-period. Congenital ptosis presented early the mean age being 23(SD ±9.91) years. Acquired ptosis presented late with the mean age of 35(SD± 14.98) years. Congenital ptosis was more common (52%) compared to acquired ptosis (48%). 4.7% of congenital ptosis had amblyopia. Among all ptosis patients, myogenic cause of ptosis was the commonest followed by mechanical, aponeurotic, traumatic and neurogenic. Simple congenital ptosis was the commonest, and among acquired ptosis, mechanical ptosis was the commonest. Most of the ptosis was unilateral (87.7%) regardless of its onset either congenital or acquired. Regarding the severity of ptosis, mild ptosis was the commonest.
Ptosis was the 3rd most common lid condition in oculoplastic clinic presentation after entropion and chalazion. Simple congenital ptosis was the commonest form of ptosis.
上睑下垂的临床表现因发病机制和上睑下垂程度不同，从美容问题到严重的视觉功能障碍不等。
研究尼泊尔西部特莱地区寻求眼部整形治疗患者的上睑下垂类型、模式及病因。患者与方法：在巴拉哈瓦蓝毗尼眼科研究所的眼部整形门诊进行了为期2年的回顾性描述性医院研究。记录了包括患者年龄、性别、患眼侧别、视力、屈光不正和/或弱视情况、上睑下垂类型及既往上睑下垂手术等人口统计学变量。
在这2年期间共有326例上睑下垂患者。先天性上睑下垂发病较早，平均年龄为23岁（标准差±9.91）。后天性上睑下垂发病较晚，平均年龄为35岁（标准差±14.98）。先天性上睑下垂比后天性上睑下垂更常见（52%对48%）。4.7%的先天性上睑下垂患者患有弱视。在所有上睑下垂患者中，上睑下垂的肌源性病因最为常见，其次是机械性、腱膜性、外伤性和神经源性。单纯先天性上睑下垂最为常见，在后天性上睑下垂中，机械性上睑下垂最为常见。无论上睑下垂是先天性还是后天性发病，大多数为单侧（87.7%）。就上睑下垂的严重程度而言，轻度上睑下垂最为常见。
上睑下垂是眼部整形门诊中仅次于睑内翻和睑板腺囊肿的第三常见眼睑疾病。单纯先天性上睑下垂是上睑下垂最常见的形式。
