RAO follow-up: What is the recommended follow-up interval for CRAO to monitor neovascularization?

• A. Every 3-4 weeks for 6 months
• B. Every 2-3 weeks for 3 months
• C. Every 6-12 months
• D. Every 12 weeks for 6 months

Answer: (A)

After CRAO, retinal ischemia can trigger neovascularization over the ensuing weeks to months. The risk period extends through about six months, so close surveillance during that time is essential. Following a cadence of every 3–4 weeks for six months allows for timely detection of iris or retinal neovascularization as it first appears, enabling prompt treatment to prevent neovascular glaucoma and preserve vision. If neovascular changes are found, treatment options such as panretinal photocoagulation or anti-VEGF therapy are considered to control the neovascular process. Less frequent follow-up or shorter monitoring periods risk missing early neovascularization during the critical window.
