Can Vision Loss Be Reversed?

Wondering if there’s anything you can do to reverse vision loss? The answer depends on the cause of vision loss, the severity of the condition or disease, and available treatment options. If you have one of these conditions, it may be possible to reverse or improve your vision.

Cataracts

A cataract is a common age-related eye condition that occurs when the lens inside your eye becomes clouded. The normally clear lens is located behind the iris, the colored part of your eye. Cloudiness affects the way light reaches the light-sensing retina at the back of your eye. Cataracts may cause blurry vision, light sensitivity, problems with glare, dull color vision, and the need for frequent changes in eyeglass or contact lens prescriptions. As clouding worsens, you may experience vision loss.

Cataract surgery reverses vision loss by replacing the cloudy lens with an artificial lens called an intraocular lens implant (IOL). Some IOLs provide sharp vision at either near or far distances, while others improve vision at all distances.

Detached Retina

A retinal detachment happens when the retina begins to peel away from the back of the eye. The light-sensing cells in the retina send electrical impulses to the brain. If the cells can’t do their job, the brain doesn’t receive the information needed to produce clear, complete images.

Symptoms of a retinal detachment include flashing lights and a sudden increase in floaters, wispy strings that float through your field of vision. You may also experience sudden vision loss and notice a dark spot in your visual field.

Fortunately, a detached retina can often be reattached if you receive treatment soon after you notice changes in your vision. Eye doctors reattach detached retinas with freezing treatment, laser surgery, or traditional surgery. Treatments can restore all or some of your lost vision. The National Eye Institute notes that retinal detachment treatments are successful for 90% of people.

Eye Infections

Eye infections, like conjunctivitis (pink eye), bacterial keratitis, endophthalmitis and orbital cellulitis, can cause blurry or double vision. Prompt treatment of these infections can restore your vision and help you reduce the risk of permanent vision loss.

Migraines

Do you notice colorful zigzag lights or blind spots just before you get a migraine? These vision changes can occur during a migraine and are called auras. Auras happen shortly before the pain of a migraine starts. Symptoms include confusion, trouble speaking, tingling, or numbness, in addition to visual changes.

Although the loss of vision is scary, vision usually returns to normal fairly quickly when the aura subsides. If you’ve never experienced vision loss with a migraine before, it’s a good idea to visit your optometrist to rule out other causes.

Central Retinal Vein Occlusion

Your vision can blur if the vein that removes blood from the retina becomes clogged. When this happens, blood and fluid leak into the retina. The accumulation of blood and fluid may cause swelling in the macula, the area of the retina responsible for central vision swells. Called “macular edema,” this condition may make straight-edged objects look wavy or colors look dull. You may be at increased risk for developing central retinal vein occlusion if you have diabetes, glaucoma, high blood pressure or hardening of the arteries.

Treatments to reverse symptoms or prevent them from worsening include medications injected into the eye to reduce swelling and laser surgery to fix the leaks in the vein.

Other Conditions

Other conditions that may be reversed or improved include retinal vasospasm, closed-angle glaucoma, giant cell arteritis, and vision loss due to multiple sclerosis complications.

It may be impossible to reverse vision loss if you’ve had a severe eye injury, damaged your optic nerve, or have a genetic degenerative eye disease. Although you can’t regain lost vision in these circumstances, a variety of low vision aids can help you make the most of your usable vision.
