The link between allergies and eye problems.

Eye Problems – Allergies

When a person has an allergic reaction, the eyes frequently become affected. Eyes turn red, become itchy and irritated, and they can also become watery. Rubbing the eyes seems to offer comfort, but the reality is that rubbing eyes that are responding to an allergic reaction often compounds the discomfort.

What are Eye Allergies?

Most often, eye allergies accompany nasal allergies, but they can occur without involving the nose. Eye allergies are triggered when an allergen makes contact with the eyes. The mast cells, which are cells inside the eyes, release histamines and other chemicals and their release triggers symptoms including irritation and inflammation.

Conjunctivitis allergies are a specific category of allergies that affect the eyes. Conjunctivitis is generally triggered by an outdoor seasonal allergen such as ragweed or grass. Conjunctivitis allergies are also known as Hay Fever conjunctivitis.

Vernal Keratoconjunctivitis is seasonal in nature and primarily impacts children. With this form of eye allergy, the edges around the outside of the cornea are affected. Atopic Keratoconjunctivitis is similar with the difference being that it affects adults. It is a chronic condition and it's one that can cause the eyes to become scarred if not treated.

Symptoms of Allergies

When exposure to an allergen occurs, the body reacts by releasing histamines. Histamine release causes fluids to build up in the nasal cavity, sinuses and also on the surface of the eye as well as the insides of the eyelids. This release is also a source of significant irritation. In addition to irritation, the eyes may become red and watery, and the eyes and eyelids can become swollen. In addition to the visible symptoms, eye allergies may cause a feeling that something is stuck inside the eye or a feeling that the eye is being scratched. Vision can also become blurry or hazy or otherwise unclear.

Who is at risk?

Any person regardless of age can develop eye allergies.

Early detection/treatment of this eye problem

The most effective treatment for allergies is to stay away from those items that trigger allergic reactions. Many everyday cosmetics including mascara, eye liners and eye brow pencils and face creams can all trigger an allergic reaction. In some individuals, eye allergies can be caused by wearing contact lenses. Dust mites, mold and pet dander can also cause eye allergies.

When allergies are suspected, detection is the key to effective treatment. It's important to note what a person had been exposed to immediately before the allergic reaction occurred. Over time, patterns will become apparent. Once the culprit has been identified, steps should be taken to restrict exposure to the allergen.

Changing the brand of cosmetics and other personal care products can help as can discussing the possibility of obtaining a different contact lens prescription with your eye care professional.

In addition to these changes, over-the-counter antihistamines, decongestants and eye drops can all help alleviate the symptoms of eye allergies. If allergies are troublesome and/or persistent, it may be time to see an allergist who can recommend prescription medications and eye drops to treat the symptoms of eye allergies.
