Ocular allergy

¿What is it? 

The ocular allergies, or allergic conjunctivitis, is a frequent condition that usually affects the conjunctive of the eye. It is characterized by recurrent and bilateral, ocular inflammation caused by certain allergens, i.e. substances that enter in contact with the eye tissues, induces a State of hypersensitivity to this substance. Ocular allergies can be seasonal (especially in spring) or perennial (year round).

The allergy is an answer of self-defense of the immune system of the person in front of the presence of an allergen.

The conjunctive is a thin transparent mucous membrane (the white of the eye) that covers the previous surface of the ocular and later balloon of the eyelids. It is the most immunologically active tissue of the eye, because it acts as a defense against infections and injuries. The conjunctive, which helps to maintain joined both the eyelids and the eyeball, is composed by the same sensitive textile as the internal recovering of the nose.

Pharmacological Treatment

Vasoconstrictors: reduce the reddening of the eye and the palpebral edema to cause vasoconstriction of the blood vessels.

Antihistamines and Antiallergics: inhibits the degranulation of mast cells and block the histamine receptors.

Non-steroidal anti-inflammatory: its effect is analgesic, anti-inflammatory and antipruritic.

Steroids: its action is purely anti-inflammatory.

Notably in terms of treatment, the first thing is know the allergy-causing agent to attack it and avoid contact with it. Although it is a question of an obviousness, there are many people who does not bear it in mind.

Go directly to a pharmacological treatment, but, if you do not prevent or counteract the cause, the effect will not be able to resolve the problem.
