Your eye care specialist will tell you how long it’ll take to recover based on your specific symptoms and what caused the hemorrhage in your eye. Most people need a few weeks to recover from surgery to repair a retinal hemorrhage.
You’ll probably need to avoid medications like over-the-counter (OTC) NSAIDs (and any other anticoagulant medication that thins your blood) while you’re recovering. Talk to your ophthalmologist about what to expect.
