Background: Blepharoptosis is abnormal low position of the upper eyelid.The effect of ptosis surgery on ocular surface is not clear and needs more clarification. Aim of this Work: To compare between levator resection and frontalis sling operations regarding tear filmand topographic changes in order to minimize postoperative morbidity and increase patient satisfaction. Patients and Methods: This study included 30 eyes of 27patients with moderate to severe ptosis and levator function within 5-6mmand with the ability to cooperate for examination and investigations. Patients were divided in a randomized manner into Two groups: Levator Resection (LR) group: 15 eyes of 15 patients underwent transcutaneous maximum levator resection. Frontalis Sling (FS) group: 15 eyes of 12 patients underwent frontalis suspension with silicon rods. The patients were subjected to complete ophthalmological examination, special lid examination, tear film examination and corneal topography. Results: In frontalis sling group, Schirmer test was constant in 53.3% of cases and increased in 46.7% of cases, On the other hand, Inlevator resection group, Schirmer test decreased in 86.7% of cases and was constant in 13.3% of cases with a statistically significant difference (p-value <0.001). Tear Break Up Time test (TBUT) decreased in 100% of frontalis sling group, however, it increased in 60% of levator resection group with a statistically significant difference (p-value <0.001). Topographic analysis revealed increase in topographic astigmatism in both groups with non-statistically significant difference (p-value 0.723). Conclusion: Frontalis sling operation adversely affects tear film quality but increases tear quantity. While levator resection decreases tear volume with improvement of tear film quality. Both operations increase topographic corneal astigmatism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
