Abstract

Abstract : Purpose: To describe the frequency of blepharoptosis and factors affecting it after the pars plana vitrectomy (PPV) procedure. Methods: In a prospective study, patients were recruited consecutively from October 2016 to June 2018. Upper eyelid margin reflex distance 1 and 2 (MRD1 and 2), upper eyelid crease height, and levator function were measured before, 1 and at least 6 months after surgery by the same investigator. Clinical and Clinically significant ptosis were defined as ≥0.5 and ≥2 mm drop of MRD1. Result: There were 60 eyes from 57 patients. The majority of surgeries were performed by the fellows (63.3%, 38/60) and under general anesthesia (95.0%, 57/60). Clinical and clinically significant ptosis following PPV were 47.2% (25/53) and 11.3% (6/53) at the last follow up (at least 6 months), respectively. MRD2 ( p = 0.389) and eyelid crease height ( p = 0.057) did not significantly change. Surgeons' level, time of the procedure and other variables were not significantly impacting the frequencies. Conclusion: Persistent clinically significant ptosis was observed in 11% of patients undergoing PPV. No variable was significantly associated with persistent postoperative ptosis after PPV. Abstract : Clinically significant postoperative ptosis was present in 20% in the first month and 11% in ≥6 months after pars plana vitrectomy.
