Neovascular glaucoma
Glaucoma
Key Points
- •NVG is caused by retinal ischemia → VEGF → rubeosis iridis → angle obstruction; the three most common causes are PDR (33%), ischemic CRVO (33%), and OIS (13%)
- •Ischemic CRVO carries a 60% risk of NVG at ~3 months - '100-day glaucoma'; monthly gonioscopy is essential in the first 6 months
- •Treatment requires a three-step approach: anti-VEGF → PRP → IOP control; anti-VEGF alone is temporary (4–6 weeks)
- •Tube shunt (Ahmed or Baerveldt) is the preferred surgical option for NVG; trabeculectomy has a high failure rate due to fibrovascular proliferation
- •AVOID prostaglandin analogues and miotics in NVG - PGAs worsen inflammation, pilocarpine increases posterior synechiae
