An ophthalmologist's view is indispensable.

A study published in Chicago, USA, during the US Academy of Ophthalmology Congress 2018 in October reveals an error in 74% of eye disease evaluations conducted by WebMD Symptom Checker, a popular online diagnostic application.

"Telemedicine is undoubtedly the way to increase access to eye health," says eye doctor Leôncio Queiroz Neto. For him, the problem with this app is to eliminate the interaction between the expert and the patient. "The result of the study is a warning to the Brazilian population," he says. .

This is because a survey done by the physician on 12,000 hospital charts shows that 4 out of 10 people already arrive at the clinic with their own eye drops. "In addition to insufficient eye drops that mask diseases, some drugs for systemic changes have an effect on eye health," he says. The highest risk groups, she notes, are elderly who treat chronic diseases, pregnant women and women taking contraceptives. But children's eyesight can also undergo changes triggered by the use of medicines,

Risk of hyperopia in children

This applies to 5% of children aged 6 to 14 years and treated with methylphenidate, active substance Ritalin and Concerta, medicines used to treat attention deficit hyperactivity disorder (ADHD).

According to Queiroz Neto, these drugs are well-considered by the country because they improve school performance by increasing concentration. The problem, he warns, is that they dilate the student and can cause courteous foresight, a temporary difficulty to look carefully.

This is what happened, with a boy in ADHD treatment who recently came to the office with his students very dilated and difficult to look carefully. The signs of occupational foresighted by the doctor are:

· He stretches his arms to read.

· Look for the last portfolios in the classroom to see the board.

· Has no taste to read

· Replace internal activities of the external

· Narrow eyes to read.

If methylphenidate can not be interrupted, it is necessary to prescribe glasses and foresight can become permanent.

Women, pregnant women and the elderly

According to the ophthalmologist who uses antibiotics, eye drops with contraceptives should be avoided as contraceptives can lose the effect.

The World Health Organization warns that 3% of birth defects are caused by the use of drugs or drugs during pregnancy. This is because the increase in sex hormones during pregnancy changes the metabolism of drugs that are concentrated in the blood.

Queiroz Neto points out that even the seemingly harmless astringent eye falls to pale the eyes can affect the fetus. This is because it contracts all ships, including the placenta. Result: it reduces the exchange of nutrients and oxygen with the fetus.

The elderly who treat high blood pressure should warn with the use of this type of eye drops as it may increase the arterial pressure, the warning. "Beta blocker's interaction with tachycardia with astringent eye drops is also contradictory because eye drops can reduce the effect of oral medication," he says.

Therefore recommends lubricating eye drops for pregnant, hypertensive and cardiac patients with their eyewitnesses. If irritation persists contact an ophthalmologist.


Queiroz Neto points out that corticosteroids can reduce the effect of eyelashes for glaucoma and should therefore be used together only during medical supervision. Pregnant women who have glaucoma must undergo ophthalmic revaluation. This is because she explains that the use of prostaglandin analogues increases the risk of early pregnancy. Beta blockers may affect the heart rate of the fetus. The good news is that intraocular pressure usually decreases during pregnancy, which in many cases allows for treatment with milder eye drops.
