Retinal detachment happens when the light-sensitive layer at the back of the eye peels away from its normal position. It is an emergency that can cause permanent sight loss if not treated quickly.
Warning signs to watch for
Detachment often starts with a small tear. Fluid then passes through the tear and lifts the retina, creating symptoms that patients may notice suddenly.
- New floaters, flashes, or a shower of black dots are common early signs.
- A dark curtain, shadow, or grey veil spreading across vision suggests detachment.
- Central vision may blur if the macula becomes involved.
- Short-sightedness, trauma, and previous eye surgery increase risk.
- One eye is usually affected first, but the other eye remains at higher risk.
Treatment and recovery
Surgery aims to reattach the retina and seal any tears. Prompt care offers the best chance of preserving reading and driving vision.
- Procedures include vitrectomy, scleral buckle, or gas bubble injections.
- Post-operative head positioning is often needed to support healing.
- Vision may take weeks or months to settle and may not fully return to normal.
- Regular follow-up checks for redetachment, cataract, or pressure changes.
- Seek urgent help for any new flashes, floaters, or shadows, even after surgery.
