Of all the diseases of the eye it is the most common is conjunctivitis. It is easily treatable, but in the absence of proper attention may become chronic or even damage eyesight (such as nearsightedness).
Features of the disease
The eyeball and the inside of the transparent cover of the century, almost invisible film. Its thickness is not greater than one millimeter. This film, which is responsible for dry eye, and there conjunctiva. When it becomes inflamed, it begins conjunctivitis. The reasons for which an illness is pretty much the main ones are:
other irritants (e.g., evaporation, chemical substances).
And viral and bacterial conjunctivitis is contagious. The only difference is that in the former case, the infection spreads through airborne droplets, and the second - in contact with the affected area. So first, as a rule, inflamed one eye and then the other. Although under certain conditions the second eye infection can be avoided.
Acute conjunctivitis is developing rapidly and has a bright symptoms and chronic, on the contrary, it proceeds rather slowly and is manifested not so clearly.
This disease can be in two forms: acute and chronic. The person experiences severe itching, pain, swelling of the eyelids (upper and lower), sometimes stinging. With the transition of allergic conjunctivitis in the chronic stage are stored only irritation of eyes and itching. The rest flows smoothed, but almost constantly. Disease manifests only on contact with the allergen.
Medicinal conjunctivitis develops within 6 hours after taking the medications. During this time, there are growing rapidly swelling, excessive tearing, itching, burning sensation in the eyes and the inability to open it. After prolonged administration of the drug appears follicular form of allergic conjunctivitis. It reminds spring catarrh. In this case, the disease progresses slowly - about 4 months. After the abolition of the drug all the symptoms gradually disappear.
Atopic conjunctivitis has a seasonal exacerbation. Often accompanied by allergic rhinitis and hay fever seen with. The manifestation of the disease is characterized by burning eyes, itching, severe pain, photophobia, and lacrimation. Also in the course of having swelling, redness and excessive mucus. For this form of allergic conjunctivitis is very dangerous secondary infection. From this age appear defeated, scarring, and hypertrophy of the papillae.
Spring catarrh common in the southern regions. He mainly affects adolescents, children and men. It has a clear affection for the season: it begins in the spring and the autumn subsides. One of the first manifestations - itching. He gradually intensified, becoming unbearable, especially in the evening. Then, swollen eyelids, conjunctiva reddens. On the conjunctiva appears tuberosity - individual papillary proliferation of dense nature. Sometimes the disease becomes severe, affecting the cornea and limb. The disease has a long duration.
Among the consequences of allergic conjunctivitis:
loss of visual acuity;
the accession of secondary infection;
blepharitis (inflammation of the eyelids);
keratitis (inflammation of the cornea);
iridocyclitis (inflammation of the iris eyes);
Diagnosis of allergic conjunctivitis
Diagnosis is based on clinical presentation. For this study the data history and characteristics of symptoms. If you want to perform a differential diagnosis with other types of the disease:
The most informative method is to bacteriological studies and bacterioscopic detachable eye and mucous membrane swabs. It is also practiced by cytological analysis of scrapings. To understand the cause of the allergic reaction is assigned to the procedure of establishing the cause of allergies. For this purpose, the skin tests and examinations of blood serum for the presence of IgE antibodies.
Despite the presence of specific symptoms, in many cases, even the doctor can not determine the cause of the disease, namely, it depends on it, what will be the treatment. Just identify the causative agent is possible only in laboratory conditions. But often such studies is not necessary, most conjunctivitis tested by themselves.
When bacterial infection effective drops or an antibiotic ointment, but are sometimes used pills and even injections. To clear the secretions from the eyelids, you should use cloth that has been soaked in boiled water. It is important to observe hygiene and produce all manipulations with eyes (to dig in, wiping) only with clean hands.
