Abstract

Purpose : To evaluate and compare intraocular pressure control, visual field defect progression and medication need in patients with chronic glaucoma before and after non penetrating deep sclerectomy (NPDS).

Methods : We included 50 eyes of 36 patients with uncontrolled chronic mild or moderated glaucoma who underwent non penetrating deep sclerectomy (alone or with phacoemulsification) with a follow up of 12 months or more. Pre and post operatory IOP, number of medications, and visual fields were evaluated and compared. Rates of visual field loss were calculated using mean defect (MD) and loss of variance (LV). Linear regression models were used to compare rates of change in visual field before and after surgery

Results : Post operatory IOP decreased 64% at 15 days, 29% at 1 year, 22% at 3 years and 24% at 6 years. Mean number of medications passed from a mean of 2.7 before sclerectomy to 0.8 at the last follow up after sclerectomy. Rates of visual field progression before and after NPDS changed from 0.07 dB/year to -0.02 dB/year for the MD; and from 0.71 dB/year to 0.61 dB/year for the LV. We found no correlation between IOP control and visual field progression.

Conclusions : NPDS improves IOP control, reduces medication needs in operated eyes and halts the potential progression of visual field loss in patients with chronic mild or moderate glaucoma.
