What is the recommended follow‑up interval to monitor for neovascularization in OIS?

• A. Every 1-2 weeks for 1 month
• B. Every 3-4 weeks for next 6 months
• C. Every 6 months
• D. Annually

Answer: (B)

Ocular ischemic syndrome creates a high risk of rapid retinal and iris neovascularization due to chronic hypoperfusion, so close, ongoing surveillance is essential in the early period to catch neovascular changes before they lead to neovascular glaucoma or vision loss. Checking every 3–4 weeks for the next 6 months provides timely detection during the interval when ischemia-driven neovascularization is most likely to progress, allowing prompt intervention with treatments such as panretinal photocoagulation or anti-VEGF therapy. Visiting only every 6 months or annually would miss rising neovascularization, and a very short, one-month intensive schedule is not sustained through the entire high-risk period. Therefore, the recommended plan is to follow up every 3–4 weeks for the next 6 months.
