Igor L, et al. - Researchers presented the effect of non-penetrating deep sclerectomy (NPDS) in severe and end-stage glaucoma treatment on the central 10° visual field progression (mean deviation, 4 central points, foveal threshold) and assess the risk of sudden visual loss. Stability of the central 10° visual field (with a trend towards improvement but non-significant) was provided by NPDS without any occurrence of “wipe-out” phenomenon and few other complications. Findings suggested considering the NPDS in end-stage and severe glaucoma on account of its low risk of complications and considerable IOP decrease with a relative stability of the central visual field.
