Visual Outcomes in Eyes With Neovascular Glaucoma and Anterior Segment Neovascularization Without Glaucoma.

To find predictive factors of neovascular glaucoma (NVG) development in eyes with anterior segment neovascularization without glaucoma (ASNVWG), and poor visual outcomes in eyes that have already developed NVG. Retrospective, clinical cohort studies. A retrospective chart review was performed on 106 eyes of 94 patients with ASNVWG and 245 eyes of 225 patients with NVG. Measured outcomes included the development of NVG at any time point of the disease for the ASNVWG arm, and a visual acuity of ≤20/200 at 6 months after initial presentation for the NVG arm. Overall, 25% of ASNVWG eyes progressed to NVG. Progression was associated with retinal vein occlusion (RVO) (P < .01), lower median presenting BCVA (P < .01), and concurrent traction retinal detachments (TRDs) (P = .025). Sixty-eight percent of NVG eyes had a BCVA of ≤20/200 by 6-month follow-up, which was associated with RVO (P = .005), vitreous hemorrhage on presentation (P = .001), and no panretinal photocoagulation (PRP) treatments (P < .001). BCVA >20/200 at 6 months was associated with ≥1 PRP or intravitreal bevacizumab (IVB) treatment within 1 week of presentation or ≥3 PRP or IVB treatments overall (P < .001). RVO, presenting visual acuity, and concurrent TRD are risk factors for NVG in eyes with ASNVWG. In eyes with NVG, RVO and concurrent vitreous hemorrhage are risk factors for ≤20/200 vision at 6 months, whereas treatment with ≥1 PRP or IVB within 1 week of presentation, or ≥3 treatments of PRP or IVB within 6 months are protective.
