The ophthalmologist is a doctor who specialized in eye care and health. As a doctor, he has the capacity to diagnose, treat and operate different pathologies. The eyes reflect a large number of diseases of systemic origin such as HBP, DM that can have ocular consequences and should be treated medically. Optometrists are health professionals, but they did not study medicine. They are dedicated to studying and treating visual problems that require the use of glasses. They can detect certain eye diseases, but they must refer them to the ophthalmologist for treatment.

They are doctors who completed one or two years more studies on a specific area, in this case ophthalmology, which means that they can provide specific and specialized knowledge for their area. They are considered in ophthalmology: Glaucoma, Retina, Anterior Segment, Oculoplastic, Neuro-ophthalmolgy, Strabismus and Ophthalmopediatrics.

An ophthalmologist can detect the need for glasses or glasses through a complete examination. Usually, the pupils are dilated to relax the focus muscles and thus achieve an accurate measurement. The examination is performed through a specialized instrument called retinoscope, which helps the ophthalmologist to achieve a formula for glasses suitable for the child.

Amblyopia is a decrease in the vision of one or both eyes, due to an abnormal development of vision in childhood. It is popularly called a lazy eye.

Vision in children is not born with them, it develops as they grow and mature. If there is a defect that requires the use of glasses or glasses and is not treated in time, the eye can not fully develop its vision. the brain learns to see blurred images and after a certain age, there is no way to improve this vision, even with the use of glasses.

The brain of a child with amblyopia usually cancels the image of the eye that sees the least, with the consequent deviation of the non-dominant eye.

On the other hand, a strabismus, or deviation of the “crossed” eyes, can produce amblyopia for the same reason, sending different messages from each eye to the brain, canceling the information of the deviated eye, with a consequent decrease in vision.

The only way is by doing an ophthalmological examination early.

Pediatricians are obliged to assess the red reflex in newborns to rule out congenital cataracts. At 2 and 3 years old, an ophthalmological examination can be done with special instruments to find any defect that requires the use of glasses.

It is important to note, if children get too close to their toys or TV, they may be needing glasses.

Keep in mind that if not treated at the right time of the child’s development (up to 8 years), in which there is still the so-called brain plasticity, visual loss can be permanent and irreversible.

Although recent studies by the National Institute of Health of the United States reveal that adolescents up to the age of 14 have recovered some vision, early treatment (before 4 or 5 years of age) usually achieves a recovery of the total vision in great majority of the cases.

It is the darkening of a natural lens that we all have in our eyes, which is called crystalline, which prevents the entry of light and perceived images.

The most frequent symptoms are: Blurred or blurred vision, changes in color vision, difficulty driving at night due to glare with light, vision of two images, improvement of near vision.

When you are starting a cataract, with a change of telescope and better lighting when reading is enough. But as it progresses, it is necessary to remove it by means of surgery and replacement with an artificial lens.

Nowadays, minimal incision techniques are used for the extraction of the cataract, which is also done by means of ultrasound, fragmenting or splitting it inside the eye. This ensures a faster recovery and minimizes the risks of infection.

Your doctor can tell you when a surgery is needed, but can not make the decision for you. It is not recommended to wait for a severe decrease in vision, as it makes the lens harder and extraction is more difficult.

Conjunctivitis is an infection that can be bacterial, viral or, in more rare cases, by fungi, on the surface of the eye. The most frequent cause is viral, it is as if you have flu in the eye.

It is associated with red eye, burning, lachrymation, piquiña and usually secretion or “legañas”.

It requires assessment by an ophthalmologist to identify its cause and treat it properly, which prevents future complications.

Like all infections, conjunctivitis is contagious. The most important prevention measure is hand washing. Never touch your eyes if your hands are not washed. If you are a contact lens user, always have a proper toilet, do not get into pools with them on and do not store them in solutions different from those commercially prepared for that.

If you suffer the fall of a corrosive or chemical liquid inside the eye, you should wash with plenty of clean water for a minimum of 10 to 15 minutes. Then immediately go to the emergency department to be evaluated by an ophthalmologist.

It must occlude the eye and go immediately to be evaluated by an ophthalmologist. If you have a sharp object or stones or glasses inside the eye, do not try to remove it, cover the eye and attend urgently for assessment and management by an ophthalmologist.

The retina is a nervous layer that covers the eye in its internal part, sending the information of what we see to the brain. The detachment of the retina consists of the separation of the retina from the layer that nourishes it and keeps it in contact with the eye. It is a serious problem, because there is a loss of vision.

It can occur at any age, but it is usually more frequent in people who are myopic or those who have had retinal disorders such as retinopathy due to diabetes. A strong blow can also cause it. There are other less common causes, such as some inherited diseases.

The appearance of “flying flies” or flashing lights may occur just before a retinal detachment. After this, the patient may notice a ripple or presence of a shadow in his vision. In many cases the esprendimiento can happen of sudden form and the patient can undergo a total loss of the vision of an eye.

The detachment of the retina or its suspicion is considered a medical emergency and must be attended without delay by an ophthalmologist. The type of treatment recommended varies depending on the cause, the state of the retina, the elapsed time.

As a general rule, surgery is usually necessary.

Retinal surgery is a much larger process than that of cataracts or the correction of refractive defects, so the patient must bear in mind that there is the possibility of not reapplying the retina in a single intervention. Approximately 85% of cases respond with a single surgery. Factors of poor prognosis are diabetes, reoperations, the presence of vitreous-retinal proliferations, high myopia, genetic syndromes or the presence of tears at a much later location.

It is an alteration of the cornea, the most anterior and transparent part of the eye, which causes it to thin out and take the shape of a cone, which produces serious visual alterations. It is more frequent in males and usually appears in adolescence, progressing over the years.

Its main symptoms is the loss of vision, since it appears a very large astigmatism, which increases permanently, to the point that correction with glasses does not improve vision.
