Retinal Detachment Can Lead to Vision Loss Within Days

Flashes of light, the appearance of floating black specks resembling falling soot, or a shadow in your field of vision. Symptoms that many people tend to ignore may be the first signs of a retinal detachment—an acute eye condition that requires immediate treatment. If left untreated, it can lead to irreversible vision loss.

Retinal detachment is one of the most serious ophthalmic conditions. It occurs when the retina separates from the underlying layers at the back of the eye, disrupting the blood supply to its light-sensitive cells. Without adequate nourishment, these cells begin to deteriorate, resulting in progressive vision loss. Prompt treatment is essential, as every hour counts.

"Once the retina detaches, immediate treatment is crucial. If a patient waits too long, scarring of the retina may occur, and restoring vision may no longer be possible," explains MUDr. Andrea Janeková, Ph.D., FEBO, FEBOS-CR, Head of the Cataract, Refractive and Vitreoretinal Surgery Centre at the Prague Eye Centre.

Who Is at Risk?

Retinal detachment is not limited to older adults. People with high myopia, diabetes, or a history of eye trauma are also at increased risk. Delayed medical attention can have devastating consequences.

"Rapid treatment is absolutely essential in acute cases. Any delay can significantly reduce the chances of preserving vision," says Dr. Janeková.

Retinal detachment is treated surgically, and the success of the procedure largely depends on how early the patient receives treatment. When diagnosed promptly, the chances of preserving vision are significantly higher. In more advanced cases, however, visual recovery may be only partial—or, in some cases, no longer possible.

For this reason, ophthalmologists urge the public not to ignore sudden changes in vision or postpone an eye examination.

Symptoms You Should Never Ignore

The most common symptoms of retinal detachment include flashes of light, the sudden appearance of numerous floaters or black specks resembling falling soot, a shadow or curtain affecting part of the visual field, and sudden vision loss.

"Retinal detachment is usually painless, which is why its early symptoms are often underestimated. If you notice flashes of light, a sudden increase in floaters, or a shadow in your field of vision, you should have your eyes examined as soon as possible," warns Dr. Andrea Janeková.

Ophthalmologists recommend that anyone experiencing these symptoms should not wait for a routine eye appointment but seek immediate medical attention at an emergency eye clinic or a specialized ophthalmology center.

Modern Treatment for Retinal Detachment

Retinal detachment is often preceded by a retinal tear. If detected early—before the retina detaches—the affected area can, in some cases, be reinforced with preventive laser treatment, reducing the risk of retinal detachment.

Once retinal detachment has occurred, however, surgery is usually required. The most common procedure is pars plana vitrectomy (PPV). The goal of the surgery is to reattach the retina, seal retinal tears, and create a stable scar at the site of the damage.

At the Prague Eye Centre, even these highly specialized vitreoretinal procedures are performed on an outpatient basis, allowing patients to return home the very same day without the need for hospitalization, making the treatment significantly more comfortable.

"Modern vitreoretinal surgery enables us to treat retinal detachment very effectively. However, the key to achieving the best possible outcome is still early diagnosis and timely treatment," concludes Dr. Andrea Janeková.
