Deep sclerectomy equally effective in POAG, exfoliation glaucoma

Performing deep sclerectomy in eyes with exfoliation glaucoma controls IOP similarly to eyes with primary open-angle glaucoma, according to a retrospective study.

Petri Rekonen, MD, and colleagues at the Kuopio University Hospital, Finland, evaluated their results performing deep sclerectomy using either a collagen or hyaluronate implant in 31 eyes (45%) with POAG and in 38 eyes (55%) with exfoliation glaucoma.

At a mean 18 months follow-up, 56.3% of POAG eyes and 44.9% of exfoliation glaucoma eyes achieved “complete success,” while 83.1% of POAG eyes and 71.6% of exfoliation glaucoma eyes achieved “qualified success,” according to the study.

No significant differences in IOP, success rates, need for glaucoma medications or complications were noted between groups. POAG eyes had a mean IOP of 18.6 mm Hg compared with 16.3 mm Hg for exfoliation glaucoma eyes. Three eyes in the POAG group (10%) and seven eyes in the exfoliation glaucoma group (18%) required reoperations. Nine eyes in each group also required YAG-descemetotomies, according to the study.

The study was published in Acta Ophthalmologica Scandinavica.
