Factors associated with the development of blepharoptosis after pars plana vitrectomy surgery

ABSTRACT

Purpose

To determine the incidence and risk factors for developing blepharoptosis after vitrectomy surgery.

Methods

This prospective observational study conducted in patients who had vitrectomy surgery at the University of California, San Francisco. The patients’ eyelids were photographed before, surgery and follow-up visits at 1 day, 1 week, 1 month, 3 months, and 6 months after surgery. Levator excursion (LE), palpebral fissure (PF) height and marginal reflex distance 1 (MRD1) changes from baseline were evaluated. Operative parameters associated with lid parameter changes were analyzed.

Results

Thirty-eight eyes were enrolled in the study. Multivariate analysis performed for PF changes from pre-operative were −0.47 mm, 0.33 mm, and 0.09 mm at 1 week, 1 month and 6 months after surgery, respectively (p-value 0.1, 0.2, and 0.8). The mean change of LE from preoperative was −0.44 mm, −0.15 mm, and 0.35 mm at 1 week, 1 month and 6 months after surgery, respectively (p-value 0.3, 0.7 and 0.4). The reduction of MRD1 at 1 week, 1 month and 6 months after surgery were −0.08 mm, −0.13 mm and −0.01 mm, respectively (p = .003, p = .6 and 0.9). Triamcinolone usage was associated with reduction of MRD1 and LE.

Conclusion

Blepharoptosis presents most during the first week after surgery. The possibility of developing transient changes in eyelid position after vitrectomy surgery should be discussed with patients.
