🚨 When sudden blurry vision is urgent!
A patient recently came to our office with a complaint of sudden, constant, painless blurry vision in one eye that started unexpectedly.
After a comprehensive eye examination and retinal imaging, we diagnosed a Central Retinal Vein Occlusion (CRVO) with macular edema.
CRVO occurs when the main vein that drains blood from the retina becomes blocked. This can lead to retinal hemorrhages, swelling of the macula (the part of the retina responsible for sharp central vision), and significant vision loss.
⚠️ Common symptoms include:
• Sudden blurry or decreased vision in one eye
• Painless vision loss
• Distorted or hazy central vision
Because macular edema can permanently affect vision, prompt diagnosis and referral to a retina specialist are critical. Many patients benefit from treatments such as anti-VEGF injections to reduce swelling and help preserve vision.
👁️ The takeaway: Never ignore sudden changes in your vision—even if there is no pain. Early evaluation can make a significant difference.
If you experience sudden blurry vision, contact your eye doctor immediately.
