Purpose: To evaluate efficacy and safety profiles of aponeurotic ptosis surgery for the eye with blepharoptosis and filtration blebs after trabeculectomy.
Methods: Subjects were 19 eyes of 18 patients who had undergone aponeurotic ptosis surgery for blepharoptosis with filtration blebs after trabeculectomy from May 2016 to November 2017 at The University of Tokyo Hospital Ophthalmology Department. The location of filtration blebs, preoperative levator function, and pre- and 1, 3 and 6 months post surgery margin reflex distance (MRD), lid fissure height, intraocular pressure (IOP), corneal conjunctival epithelial disorder (fluorescein staining score), tear meniscus height and Schirmer test were evaluated. We also assessed postoperative complications.
Results: Subject's mean age was 72.6±10.3 years old. The location of filtration blebs were 12 eyes at superotemporal and 7 eyes at superonasal. Pre levator function was 11.1±2.3 mm. MRD and lid fissure height improved at 1, 3 and 6 months post surgery. IOP, fluorescein staining score, tear meniscus height and Schirmer test showed no significant change after surgery compared to those preoperatively. There was no case of leakage and infection of blebs after ptosis surgery. One eye showed recurrent ptosis at 1 month. In all other 18 eyes, subjective symptoms were improved.
Conclusion: Aponeurotic ptosis surgery was effective and could be performed safely even in cases with filtration bleb.
