Allergic conjunctivitis

Allergic conjunctivitis is the inflammation of the conjunctiva (the membrane covering the white part of the eye) due to allergies.

Although allergens that trigger the conjunctivitis differ among patients, the most common cause is hay fever. If this is combined with rhinitis, the condition is termed allergic rhinoconjunctivitis.

Pollen allergies are mostly seasonal, whereas allergies to animal fur can be triggered at any time.

Symptoms consist of redness (mainly due to vasodilation of the peripheral small blood vessels), edema (swelling) of the conjunctiva, itching, and increased lacrimation (production of tears).

Most people with allergic conjunctivitis also suffer from generic allergic symptoms such as sneezing, sniffling/runny nose – and sometimes even asthma.

Avoiding allergens will help prevent symptoms. Allergies to the family pet can be controlled by removing the animal and finding it a new home. Exterminating cockroaches, mice and rats and a thorough house cleaning can reduce symptoms of an allergy. Dust mites are attracted to moisture. They consume human skin that has come off and lodged in furniture, rugs, mattresses, box springs and pillows. Bedding can be covered with allergen-proof covers. Laundering clothing, bed linens and blankets with non-allergic powder will also reduce exposure.

If you know what you are allergic to, you should firstly avoid the allergen that is causing your problems. Otherwise, both prescription-free and prescription drugs with antihistamine and cortisone are available to relieve the problems.

If you have a serious problem or do not know what is causing your allergy, a doctor can do an allergy examination. In case of severe allergies you can receive treatment in the form of an allergy vaccination, called allergen immunotherapy.

If you have a long-lasting problem or if you have severe symptoms, it is important to consult your doctor.
