Evaluation of Maximum Levator Resection in Correction of Blepharoptosis with Poor Levator Function

Background: Cosmetic and functional complications result from ptosis, which is the third most prevalent eyelid disease after chalazion and entropion and involves unilateral or bilateral drooping of the upper eyelid. Ptosis has the potential to result in amblyopia. Additionally, a relatively mild ptosis may induce obstruction in the upper visual field. Ptosis can also induce psychological complications among adolescents and young adults. Ptosis may be categorized as either congenital or acquired.Aim: To evaluate maximum resection of the levator muscle in the ptosis correction with poor levator function in comparison with the frontalis suspension procedure.Patients and Methods: This prospective randomized, non-controlled comparative study involved thirty patients presenting with poor levator function less than 5 mm. Fifteen participants underwent maximum levator resection, and fifteen patients underwent a frontalis sling procedure using facia lata. It was carried out at the Department of Ophthalmology, Al-Azhar University Hospital.Results: No statistically significant difference was observed between groups regarding sex, age, operated side, MLD and corneal sensitivity, preoperative VPFH and preoperative LF. There was statistically significant reduction after 6 months follow up in VPFH in MLR group than FS group, there was statistically significant reduction after 6 months follow up in MRD and decrease MRD changes in MLR group than FS group.Conclusions: The maximum levator resection may have an augmenting role in managing cases with severe ptosis and poor levator function.
