Retinal Detachment
A medical emergency where the retina peels away from its underlying layer, potentially causing permanent vision loss if not treated promptly.
Retinal detachment happens when the retina; the light-sensitive layer at the back of the eye, pulls away from its normal position. It is a medical emergency because untreated detachment can cause permanent vision loss.
Causes & risk factors:
Age-related changes in the eye’s gel (vitreous)
Severe nearsightedness (myopia)
Eye injuries or previous surgery
Family history of retinal problems
Warning signs:
Sudden increase in floaters
Flashes of light in one eye
A dark shadow or “curtain” across vision
Sudden blurred or lost vision
Diagnosis & treatment: An eye doctor uses a dilated exam to check the retina, sometimes with an ultrasound. Treatment depends on severity:
Laser or freezing (cryotherapy): Seals small tears
Gas bubble (pneumatic retinopexy): Pushes retina back in place
Scleral buckle or vitrectomy surgery: Repairs larger detachments
Act fast: If you notice flashes, floaters, or a curtain-like shadow, seek emergency eye care immediately.
