Background

This study evaluated the incidence and progression of ptosis during the first year after glaucoma surgery.

Purpose

This study evaluated the incidence and progression of ptosis during the first year after glaucoma surgery.

Methods

Included microhook ab interno trabeculotomy (µTLO), Preserflo MicroShunt (Preserflo MicroShunt), trabeculectomy, and Ahmed glaucoma valve (ahmed glaucoma valve).

n = 167 patients
Results
32.3%
eyelids drooped after surgery, worse in about a third of eyes
n = 167 patients
More results

Mean (SD) MRD-1 decreased from 2.5 (1.2) mm preoperatively to 2.1 (1.3) mm at one year.

MRD-1 decreased significantly from 1 month through 1 year, whereas MRD-2 showed only a transient decrease at 1 month.

More results

No significant MRD-1 reduction occurred after µTLO, whereas significant decreases were observed after filtration surgery.

Ahmed glaucoma valve implantation and higher preoperative MRD-1 were associated with ptosis.

“
Conclusion

Ptosis occurred in about one-third of eyes after glaucoma surgery and progressed up to one year. Filtration surgery was associated with a higher risk of postoperative ptosis.
