RVO follow-up: After RVO treatment, how often should neovascularization be monitored?

• A. Annually
• B. Monthly
• C. Weekly
• D. Every two years

Answer: (A)

The key idea here is long-term surveillance for recurrent neovascularization after treatment for retinal vein occlusion. Once neovascularization has regressed with therapy (anti-VEGF and/or laser), the immediate danger is reduced, but the underlying ischemic drive can persist and late recurrences are possible. Annual monitoring strikes a balance: it provides a regular check for any re-emergence of new vessels or late ischemic changes without demanding the patient come in very frequently if the eye has stabilized. More frequent visits (monthly or weekly) are typically reserved when there is active disease or ongoing ischemia, while waiting two years between checks risks missing a late recurrence. So, after treatment and stabilization, yearly follow-up is a reasonable standard for ongoing neovascularization surveillance.
