Abstract
PURPOSE
There is an increased risk for development of blepharoptosis after incisional glaucoma surgery. Data on safety and efficacy of ptosis repair in this group of patients in limited. The goal of this study is to evaluate outcomes and identify potential risk factors for failure of ptosis repair in eyes with history of incisional glaucoma surgery.
METHODS
A retrospective chart review was performed of all patients who underwent incisional glaucoma surgery, specifically trabeculectomy or implantation of glaucoma drainage device (GDD), and subsequent ptosis repair at a single institution from 2009 to 2019. Ptosis surgery outcomes were compared to a control group who underwent ptosis repair after cataract surgery.
RESULTS
Seventy-eight eyes of 64 patients were included in the glaucoma surgery group. The rate of severe ptosis (margin reflex distance 1 ⩽ 0 mm) among glaucoma surgery patients was higher compared to control (35 of 78 (44.9%) vs 23 of 82 (28.6%). Ptosis repair was successful in 59 of 78 eyes (75.6%), which was similar to control. Risk for revision surgery was increased more than five-fold in the GDD group compared to control. There were no cases of early or late bleb-related complications.
CONCLUSIONS
Ptosis repair can be performed safely in patients after incisional glaucoma surgery. Müller muscle conjunctival resection and external levator advancement are equally effective. Patients with history of GDD should be advised about the potentially increased risk of need for revision surgery.
