More and more people suffer from "dry eye" syndrome


Dry eye syndrome may affect 3 to 10 people, depending on air and environmental pollution and symptoms that may affect their ability to perform daily activities.

Professionals have more cases of dry eye syndrome in consultations due to increased environmental pollution affecting the major cities, artificial ventilation of indoor environments and high exposure to screens.

In addition, there is a greater susceptibility to women over 40 years of age.

The so-called & quot; dry eye & quot; syndrome is characterized by a change in tear production, which causes eye irritation, itching, and contact lens disorders during the production of eye lenses.

In addition, experts stressed that failure to cure could have serious consequences.

"The eyelid can cause permanent friction and friction damage. Graphically, we can say that the eye works as an automobile windshield wiper: if you open it with dry glass, it will draw and disrupt it. its cover hurts it, 39 explained Alejandro Aguilar, an ophthalmologist in ocular surface diseases, the founder and former president of the Oculus Surface Association of Argentina.

"A multifactorial syndrome that can affect 30% of the population. An increased number of cases were identified because of long-term exposure to screens, artificial and natural environmental changes, and improvement in diagnostic methods," he said.

In addition to being exposed to a dry and windy climate, smoke and air conditioning accelerate the evaporation of tears, thus avoiding contact with these disturbing conditions, may reduce the likelihood of dry eyes or suffer

Alejandro Berra, chief investigator of Conicet and head of SASO, said, "The symptoms suffered from dry eyes and those living in big cities like Buenos Aires are getting worse," he said. more severe. "

& A few years ago, we did a job with park guards from Los Glaciares National Park, where we observed that the tears of these people, which lasted 8 to 11 hours, deteriorated in 14-20 seconds. In the case of a person with no dry eye and a living person, it deteriorates in 7-8 seconds.

This means less interference with tears and less interference from particles in the air and better visual quality. In any case, it does not mean that people living in areas free of pollution will not develop their dry eyes because there are other conditions that affect their development. "Said.

In addition, the screen of the PC to stay more than 5 hours a day supports the appearance of this situation with its mobile phone or TV screen.

A Mexican study found that 86.4% of those attending an ophthalmological consultation had symptoms consistent with dry eye syndrome.
"Those who have more time in front of the screen will flash less and therefore the tears will evaporate faster. Often, the devices are not ergonomically positioned, not at the right distance. They may even affect the calibration of the device's brightness," says Berra.

For experts who cannot ignore the fact that experts are a significant daily work quota in front of the screen, advice for periodic flashing when looking at a computer, even those who spend a lot of time or do other work that requires visual concentration is recommended.

Other recommendations for those who work for more than four hours per day at the computer are: annual consultation to the ophthalmologist (if he / she does not already have an ocular pathology); If they wear glasses, review their graduation once or twice a year; Use eye lubricant every 6 or 8 hours during work; Resting times and movements of the neck and limbs every 30 minutes from the screen.

It may be useful to use between 11 and 12 fonts, as well as limiting the use of video games up to one or two hours per day.

A syndrome more common in older women

The age at which dry-eye syndrome may occur is variable, but for visits to the ophthalmology that causes symptoms in people over 40 years of age and in women with a very severe syndrome in the climacteric period.

In fact, menopause-related hormonal changes are one of the main causes of women being most affected by dry eye condition.
This is because hormonal changes are transformed into changes in the production of tears. And not only hormonal changes that occur in menopause. Different conditions, including autoimmune diseases such as lupus and rheumatoid arthritis, which affect the functioning of the lacrimal gland or its ducts, envisage a reduction in tear secretion and thus the development of dry eye syndrome.

Treatment and prevention measures

Depending on the severity of dry eye syndrome and symptoms, conventional therapy is pharmacological and local using artificial lubricants, drops, gels or ointments.

In more severe cases, autologous serum drops or eye drops of immuno-modulating drugs are indicated, and it is common to prevent the tear discharge channels of the tears with implants to keep the tears on the tears.

In any case, the main purpose of the treatment is to break the vicious cycle of this condition and restore the stability of the ocular surface and the tear film.
General measures, such as the use of sunscreen and windshield protection with appropriate glasses, are very useful when environmental conditions are required.

Other useful measures include: do not smoke and avoid indirect smoke, direct wind and air conditioning; Use moisturizer especially in winter; it can dry the ocular surface and reduce the use of allergies and cold medications that worsen symptoms; it blinks more often and rests your eyes from time to time; Clean lashes regularly and apply hot compresses.

The timely and adequate treatment of dry eye syndrome allows its progression to avoid the effects that may cause ulcers by severely damaging the cornea and may require corneal transplantation even in more advanced conditions.

The transplant is a surgical procedure that replaces a cornea with a healthy cornea that is damaged by trauma, infections, corneal deformities, or degenerations. (Na)
