Corneal opacity - key features, dangers and approaches to therapy

Belmo on the eye is a common problem with eyesight.Often this visual defect is used in a figurative sense, as something that interferes. And indeed, this defect greatly hinders a person and, if it develops sufficiently, can even lead to the fact that a person will lose the ability to see. And there is a pathology in the opacity of the cornea of ​​the eye. We will understand why it arises and what to do with it.

Definition of a symptom

Blurred vision is the appearance of cicatricial changes in the retina of the eye, which is responsible for a person's central vision.As a result, a person begins to see badly any objects that are directly ahead. Over time, the situation can be aggravated even more.Such a manifestation is called a thorn in the eye.

Most often, people of age are affected, but there are many reasons and prerequisites for the development of the disease in young people.

Previously, the appearance of the belly was almost guaranteed to lead to blindness, but the development of modern medicine has led to the fact that such situations are currently the exception rather. There is also a correlation between cataract and cataract, described here.

Causes

There are several different factors that can lead to the development of this problem. These include, but are not limited to, the following:

• Viral infection.For example, the cause may be a fairly common viral conjunctivitis, which is often accompanied by inflammation of the cornea.
• Damage to the cornea.After disturbing its surface layer, a bacterial infection can often be added, which simply corrodes the cornea, forming an ulcer. The ulcer can eventually turn into a special kind of scar, called a thorn.
• Consequences of the operation.On the inner surface of the cornea are the so-called endothelial cells, which after damage are not always restored. In addition, their number decreases with age. If a person does not have a very successful surgical intervention, then there may be a lack of these cells decompensating the cornea, which will lead to its further turbidity.

There are other reasons that can provoke the development of the problem. For example, the natural age changes occurring in the human body.Also common causes are lack of vitamin A, as well as improper wearing of contact lenses, resulting in the latter accumulate pathogenic organisms, which adversely affect human vision. Such a disease is called acanthamoebic keratitis.

Concomitant symptoms

The opacity of the cornea can be determined by a number of concomitant symptoms, which may include the following:

• Photophobia.
• Enhanced lacrimation.
• Redness of the eyes.
• Slight vision impairment, especially in situations where the middle part of the cornea is affected.
• A constant sense of presence in the eye of an alien object, which, of course, in the eye there.

Of course, it is possible to define this symptom not only by indirect signs, but also simply by an unaided eye. You can, as a rule, see a fairly characteristic whitish spot - the thorn.

If the throat is in the central part and is large enough, then the vision falls very seriously, only the light perception remains.

Possible diseases

There are a number of diseases of various origins that can lead to clouding of the cornea of ​​the eye. Among other things, they include the following:

• Keratite(inflammation of the cornea of ​​the eye)
• Herpes virus.Provided that it falls directly on the cornea.
• Conjunctivitis andsimilar to him ophthalmic infections.
• Syphilis,tuberculosis and a number of other diseases. Belmo can develop as a complication from them.

Diagnostics

Since the opacity of the cornea in many situations can be diagnosed simply visually, then the diagnosis begins with a visual inspection, anamnesis and visual acuity testing.

If during this time suspicions of corneal opacity were identified, then they resort to a special apparatus called the "Amsler lattice".When using this device, the patient needs to focus the eye on the point, which indicates the ophthalmologist. If the adjacent lines appear to the patient not straight, but wavy, then the likelihood of the corresponding pathologies developing in the eye is great.

Amsler test

If even at this stage one can not fully confirm the diagnosis, then resort to further procedures, namely ultrasound of the visual organs and biomicroscopy. But the most accurate method of detecting the pathology in question is coherent optical tomography. Its principle lies in the fact that different organs of vision reflect light waves differently. As a result, it becomes possible to diagnose not only accurately, but also extremely painlessly.

Treatment

At the base stages of the disease, when there is residual inflammatory infiltration in the region of the belly, it is sufficient to perform basic conservative local treatment.Can use such drugs as Prednisolone, Cortion, Hydrocortisone and a number of others. It is also possible to accelerate the process of resorption of the throat by instilling into the eye a solution of ethylmorphine hydrochloride.

Prednisolone - used in the treatment of corneal opacity

Other drugs that can be prescribed for treatment include yellow mercury ointment, proteolytic enzymes and others means, which the treating doctor must definitely appoint on the basis of what reason provoked the development of turbidity eye.

If the throat is large, then conservative treatment is contraindicated as ineffective.Mandatory surgical intervention is necessary. This can be a laser operation, and can be keratoplasty, during which the part of the cornea that has undergone pathological changes changes to a special graft.

Thermokeratoplasty with laser.

Some people have individual contraindications to surgery. For them, the restoration of vision is not possible, only cosmetic correction of pathology with the help of contact lenses is allowed.

Prevention

Do not forget about preventive measures. They can not guarantee 100% that the problem will not arise, but they minimize the chances of its appearance. These include:

• Mr.sunglasses to minimize exposure to ultraviolet radiation;
• rational nutrition, which includes a balanced set of vitamins;
• fast treatment of any diseases, which can occur in the body so that they do not have time to act on the eyes;
• minimizing the consumption of fatty foods.

conclusions

The opacity of the cornea of ​​the eye is a very serious and dangerous phenomenon for the eyesightI. Fortunately, in most cases, you can cope with the problem by providing immediate treatment. But remember, the earlier you contact an ophthalmologist, the higher the chance that you can quickly cope with the problem and restore your eyesight as much as possible in your situation.
