Original articleFactors Associated With Surgical Outcomes in Congenital Ptosis: A 10-Year Study of 319 Cases
Section snippets
Methods
This retrospective study followed the tenets of the Declaration of Helsinki and was approved by the Institutional Review Board of Chang Gung Memorial Hospital (CGMH), Taiwan (104-8979B) in 2016. A waiver of consent was granted because of the retrospective nature of the project and anonymous analysis of data.
We retrospectively reviewed the medical records of all patients with congenital ptosis diagnosed and treated at the Department of Ophthalmology, CGMH, between January 1, 2006 and December
Demographics
Of the 319 patients enrolled in this study, 205 (64.3%) were male, and the distribution difference between sexes was significant (P < .001). Among the patients, 77.7% had unilateral ptosis and 22.3% had bilateral ptosis. In the unilateral group, the laterality of the affected eye was evenly distributed. Regarding the severity of ptosis, 79.7% of cases were severe, 18.5% were moderate, and 1.8% were mild.
The mean age at surgery was 3.86 ± 2.85 years. Age group analysis showed that 78 patients
Discussion
The definitive treatment for congenital ptosis is surgery, and the primary goal is to restore the eyelid position to as normal a level as possible. The main challenges to effective treatment are the optimal timing of surgery and the type of surgery, which may vary from case to case.17 Surgical correction of congenital ptosis is delayed as much as possible to ensure better surgical outcome if there is no risk of amblyopia.3 Early surgery may be indicated if visual development is compromised, as

Levator muscle resection for simple congenital ptosis: its impact on preoperative levator function and dose-response ratio
2023, Canadian Journal of OphthalmologyCitation Excerpt :It is likely that if patients with lesser levator function entered the study, successful outcomes would be reduced. Similar to other studies, undercorrection was the most common complication.7–11 One of the limitations of this study is its retrospective design, which predisposes it to errors such as measurement error.
Upper eyelid taping to stimulate visual development in amblyogenic congenital ptosis
2022, Journal of AAPOSCitation Excerpt :In infants with a documented decrease in vision, amblyopia management is often instituted but generally followed soon thereafter by surgical intervention.2,3 Although the frontalis muscle is well developed by 2 years of age,4 the orbit exhibits the most growth between birth and 5 years of age,5,6 often rendering the result of the frontalis suspension variable and temporary.3 Postoperative recurrence is more likely to occur in children younger than 3 years of age and significantly so in children less than 1 year old.5
