Types Of Allergic Eye Disease

There are various types of allergic eye disease but the main types are seasonal, perennial and contact allergic conjunctivitis, atopic keratoconjunctivitis, vernal keratoconjunctivitis and giant papillary conjunctivitis. Here I will go through these types of allergic eye disease.

Seasonal Allergic Conjunctivitis

This type of eye disease, as its name suggests, is seasonal and affects people depending on the type of pollen, such as weed pollen; this is released in late autumn, tree pollen; this is released during spring, and grass pollen; this is released during the summer months. It normally comes as a side effect of hay fever. Common symptoms include irritated, red, and watery eyes. The eyelids can be swollen or puffy.

Perennial Allergic Conjunctivitis

This eye allergy has the same symptoms as the seasonal form but they occur all year round instead of certain times depending on air pollen. The symptoms of this type of eye disease are generally milder than its seasonal cousin. With this year round allergy, people have a response to mold, pet hair, dust and other domestic allergens.

Atopic Keratoconjunctivitis

This type of allergic eye disease is a form of eye allergy that is severe and involves the inner lower lid lining but can also include the cornea. Atopic keratoconjunctivitis mainly affects young adults but can persevere for years and can occur all year round. A lot of people who suffer with this type of eye allergy usually suffer allergic rhinitis, atopic dermatitis and sometimes asthma. Symptoms can include burning, intense itching, redness and the production of thick mucus. Common causes are dust mites and pet hair amongst others. If atopic keratoconjunctivitis is left untreated complications can occur such as corneal scarring and infection, this is why it is very important to seek attention from an eye doctor if you feel you suffer from this type of allergy.

Vernal Keratoconjunctivitis

Vernal keratoconjunctivitis is more serious than some other types of eye allergies. It mainly affects boys and young men who mostly have a family history of allergies or have eczema or asthma. Symptoms include itching, photophobia, foreign body sensation, intense tearing and thick mucus production. Visually the eye area may be swollen and red and there are hard bumps underneath the upper eyelid. It can affect people all year round but symptoms can get worse seasonally. If left untreated this eye allergy may impair vision and in very severe circumstances can cause corneal ulcers leading to scarring.

Contact Allergic Conjunctivitis

This type of eye allergy is caused by contact lens irritation which is caused by an allergic reaction in the conjunctiva or it can be caused by the proteins found in tears binding to the surface of the lens. Symptoms include itching, redness, mucus and being uncomfortable in contact lenses. It is best to go to your eye clinic if you feel you are suffering with this before it gets worse. Your eye specialist may recommend changing your contact lenses and/or contact lens solution.
