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 < 0.0001). The mean intraocular pressure showed no significant change from 12.9 ± 2.6 mm Hg before surgery to 12.7 ± 3.3 after surgery. In the filtering bleb analysis using anterior segment optical coherence tomography no significant differences were found, such as in bleb volume, height and wall thickness, before and after blepharoptosis surgery. There were no intraoperative complications in any of the cases. A postoperative corneal disorder was seen in 1 eye, but there was no infection of or damage to filtering bleb in any of the cases during the postoperative follow-up period. CONCLUSIONS: In patients with glaucoma filtering bleb, transcutaneous levator aponeurotic ptosis surgery is considered to be safe and unlikely to affect the morphology of the filtering bleb or intraocular pressure in the short term.In patients with glaucoma filtering bleb, transcutaneous levator aponeurotic ptosis surgery is considered to be highly safe and unlikely to affect the morphology of the filtering bleb or intraocular pressure in the short term.
