Symptoms

Retinal detachment itself is painless. But warning signs almost always appear before it occurs or has advanced, such as:

• The sudden appearance of many floaters — tiny specks that seem to drift through your field of vision
• Flashes of light in one or both eyes (photopsia)
• Blurred vision
• Gradually reduced side (peripheral) vision
• A curtain-like shadow over your visual field

When to see a doctor

Seek immediate medical attention if you are experiencing the signs or symptoms of retinal detachment. Retinal detachment is a medical emergency in which you can permanently lose your vision.
