摘要

AIM: To evaluate outcomes of combined pars plana vitrectomy and Baerveldt glaucoma implant(PPV-BGI)placement for refractory glaucoma.·METHODS: The medical records of 92 eyes(89patients) that underwent PPV-BGI were retrospectively reviewed, including 43 eyes with neovascular glaucoma(NVG) and 49 eyes with other types of glaucoma(non-NVG).·RESULTS: Outcome measures were visual acuity(VA),intraocular pressure(IOP), glaucoma medical therapy,complications, and success (VA >hand motions(HM),IOP ≥6 mm Hg and ≤21 mm Hg, no subsequent glaucoma surgery)Cumulative success rates for the non-NVG group and NVG group were 79% and 40% at1 y, respectively(P =0.038). No difference in the rates of surgical success were found between pars plana and anterior chamber tube placement. Preoperative IOP(mean±SD) was 30.3±11.7 mm Hg in the Non-NVG group and 40.0 ±10.6 mm Hg in the NVG group, and IOP was reduced to 15±9.5 mm Hg in the non-NVG group and 15±10.5 mm Hg in the NVG at 1y. Number of glaucoma medications(mean ±SD) decreased from 2.7 ±1.3 in the non-NVG group and 2.8 ±1.3 in the NVG group preoperatively to 0.76 ±1.18 in the non-NVG group and0.51±1.00 in the NVG group at 1y. Improvement in VA of≥2 Snellen lines was observed in 25(27%) eyes,although only 33% of non-NVG eyes and 2.3% of NVG eyes maintained VA better than 20/200 at 1y. Nonclearingvitreous hemorrhage was the most common postoperative complication occurring in 16(17%) eyes,and postoperative suprachoroidal hemorrhages developed in 5(5.4%) eyes.·CONCLUSION: PPV-BGI is a viable surgical option for eyes with refractory glaucoma, but visual outcomes are frequently poor because of ocular comorbidities,especially in eyes with NVG. The location of tube placement does not influence surgical outcome and should be left to the discretion of the surgeon.
