Hospiten highlights the sudden appearance of spots and lightning-like flashes as warning signs to visit the ophthalmologist, as these can be some of the main symptoms of a possible posterior vitreous detachment and thus help to avoid more serious future complications.

"Posterior vitreous detachment is a natural process in the eye that does not usually require treatment, but we must be alert to its possible complications," says Dr. Paula Larrañaga, ophthalmologist at Hospiten Bellevue University Hospital and Hospiten Tamaragua.

Posterior vitreous detachment is a condition in which the vitreous -a gelatinous substance that fills the inside of the eye- separates from the retina. "It is part of the natural evolution of our ocular structures and usually occurs after the age of 50, although it can also appear earlier in myopic people or those with a history of eye trauma," explains the doctor.

One of the most characteristic signs of this phenomenon is the sudden appearance of "floaters" (small moving spots in the visual field) and, in some cases, flashes of light similar to lightning. "Many people already perceived some small flies previously, but when the complete vitreous detachment occurs, these symptoms usually intensify," the specialist explains.

"In most cases, vitreous detachment does not require any treatment. It is a benign and self-limited process," reassures Dr. Larrañaga. However, she warns that in approximately 10% of cases complications such as hemorrhages, tears or even retinal detachment can occur, situations that do threaten vision and require urgent intervention, either with laser or surgery.

"Generally, floaters diminish over time and are only noticeable in high-contrast situations, such as when looking at a white wall or on very sunny days. The flashes also tend to disappear progressively," he says.

"It is essential to see an ophthalmologist if new spots or flashes appear suddenly, or if you notice a sudden increase in existing floaters. In consultation, we perform a detailed examination of the retina to rule out any complications that could compromise vision," concludes the doctor.

Knowing the symptoms and acting in time is key to preserve eye health and prevent permanent damage. When in doubt, consulting a specialist is always the best option.
