Purpose: To evaluate the effectiveness and safety of aponeurotic blepharoptosis surgery and the morphology of filtering bleb in patients with filtrating bleb.
Methods:
This retrospective case series included 7 consecutive patients (9 eyes) with filtering bleb after trabeculectomy. They underwent transcutaneous levator aponeurotic advancement from May 2018 to April 2019. The authors evaluated margin reflex distance-1 and intraocular pressure and analyzed filtering bleb morphology, such as filtering bleb volume, filtering bleb height, and filtering bleb wall thickness, using anterior segment optical coherence tomography before and after aponeurotic advancement. The authors also evaluated intra and postoperative complications.
Results:
The mean age was 75.6 ± 7.8 years; the mean duration from glaucoma surgery to blepharoptosis surgery was 36.9 ± 26.8 months; the mean follow-up after blepharoptosis surgery was 6.1 ± 2.9 months. The mean margin reflex distance-1 value changed significantly from 0.7 ± 0.8 mm before surgery to 3.3 ± 0.4 mm after surgery (p
