Surgical results of pars plana vitrectomy combined with pars plana lensectomy with anterior capsule preservation, endophotocoagulation, and silicon oil tamponade for neovascular glaucoma.

PURPOSE: To report on pars plana vitrectomy (PPV) combined with pars plana lensectomy (PPL) with a preserved anterior capsule, panretinal endophotocoagulation (EPC) throughout the pars plana, and silicon oil (SO) tamponade (PPV + PPL + EPC + SO tamponade) for neovascular glaucoma (NVG).

METHODS: Thirteen eyes with NVG were treated. Ten eyes also underwent SO removal and intraocular lens (IOL) implantation (SO removal + IOL). Intraocular pressure (IOP), number of medications, and visual acuity were evaluated at the first visit, immediately before and 3 months after the procedure, 3 months after SO removal + IOL, and 1 year after the procedure.

RESULTS: At the first visit, immediately before and 3 months after the procedure, 3 months after SO removal + IOL, and 1 year after the procedure, the IOPs were 29 ± 19, 23 ± 12, 13 ± 5, 17 ± 10, and 17 ± 6 mmHg; numbers of medications, 0.7 ± 1.4, 2.1 ± 2.0, 0.6 ± 0.7, 1.2 ± 1.2, and 1.6 ± 1.6; and best-corrected visual acuities converted to logarithm of the minimum angle of resolution (BCVA logMAR), 0.96 ± 0.96, 1.27 ± 0.80, 1.67 ± 0.91, 1.37 ± 0.89, and 1.90 ± 1.44, respectively. No severe hypotony or phthisis bulbi developed within 1 year after the procedure. The success rates (IOP ≤ 21 mmHg and sustained light perception) were 92.3% after 3 months and 69.2% after 1 year.

CONCLUSION: PPV + PPL + EPC + SO tamponade might have prevented acute increases of vascular endothelial growth factor and inflammatory cytokine production postoperatively and resulted in good vision in patients with NVG.
