Warning Signs of Retinal Detachment

What a retinal detachment is

A retinal detachment happens when the retina separates from the back wall of the eye. The retina can no longer work normally when it is detached, which is why prompt treatment matters. Early evaluation can prevent a small detachment from progressing into a larger one.

Many detachments start with a retinal tear, which allows fluid to pass underneath the retina. When that happens, vision can change quickly, especially if the macula becomes involved. Immediate evaluation protects the best chance of preserving central vision.

Detachments are typically painless, which can delay care. Any sudden change in vision should be treated as urgent, even if it comes and goes.

How flashes, floaters, and curtain vision can look

Symptoms vary by person, but they often include new floaters, flashing lights, or a dark shadow in the field of vision. The images below are visual examples to help patients recognize what these changes may feel like.

Flashes can look like brief lightning streaks in your peripheral vision. Floaters may look like spots, threads, or cobwebs drifting across your sight. A curtain-like shadow can suggest that part of the retina is no longer functioning normally.

Who is at higher risk

Risk factors include a personal or family history of retinal detachment, prior eye injury, or previous eye surgery such as cataract surgery. High myopia and certain retinal diseases, including diabetic retinopathy, can also increase risk.

Aging changes inside the eye can lead to posterior vitreous detachment, which may cause a retinal tear in susceptible patients. This is why new symptoms should always be evaluated, even if you have had floaters before.

If you notice symptoms in either eye, do not wait for them to improve. A dilated eye exam is needed to rule out a tear or detachment, even if the symptoms seem mild at first.

How it is diagnosed and treated

Diagnosis is made with a dilated retinal exam. Additional imaging may be used to confirm the extent of the detachment and identify any retinal tears. Prompt evaluation helps determine whether laser, freezing therapy, or surgery is needed.

Treatment depends on the location and size of the detachment and may include pneumatic retinopexy, scleral buckle surgery, or vitrectomy. Early treatment leads to better visual outcomes, especially before the macula is involved.
