What Is Allergic Conjunctivitis?

Allergic Conjunctivitis is a type of Conjunctivitis characterised by inflammation of the conjunctiva or the tissue that lines the eyelids. It results from a natural reaction of the body against allergens like dander and pollen.

In Allergic Conjunctivitis one eye or even both eyes may be affected.

Allergic Conjunctivitis Types

Medical researchers divide Allergic Conjunctivitis into five subtypes. These are

  • Seasonal Allergic Conjunctivitis
  • Perennial Allergic Conjunctivitis
  • Vernal Keratoconjunctivitis
  • Atopic Keratoconjunctivitis
  • Giant Papillary Conjunctivitis

In Allergic Conjunctivitis redness is the most common symptom. The first sign of this disorder is redness of the affected eye.

In Allergic Conjunctivitis watering eyes are another common difficulty. There is almost persistent discharge from the eyes which leads to blurry vision.

Covering of the white

Allergic Conjunctivitis causes the widened vessels in the transparent eye tissue to cover the white of the eye.

Allergic Conjunctivitis Causes

As aforesaid, Allergic Conjunctivitis is caused due to exposure of the eyes to allergens. On exposure to allergenic substances, the immune system suspects an infectious or cancerous attack on the body cells. The mast cells release an organic compound known as histamine as a natural reaction to this. This leads to inflammation of the blood vessels in the Conjunctiva. Naturally, the eyes take on a swollen appearance to block the foreign substances. All the symptoms of Allergic Conjunctivitis arise due to this condition.

Allergic Conjunctivitis Triggers

Common allergens that trigger Allergic Conjunctivitis are

  • Pollens
  • Cosmetic products
  • Dust
  • Smoke
  • Perfumes
  • Dander
  • Mold

Animal secretions, eye drops and skin medicines are also found responsible in some cases. Pet saliva, hairs and fur can also give rise to allergies of the Conjunctiva.

Allergic Conjunctivitis Diagnosis

The diagnosis of Allergic Conjunctivitis is generally made through clinical studies. People suspected to be having Allergic Conjunctivitis have to undergo a physical examination. If diagnosis of the disorder becomes difficult, a number of tests may be performed for diagnosis.

Conjunctival scrapes are usually taken and analysed in the laboratory to check for presence of allergens. Doctors look for white blood cells known as Eosinophils in eye secretions and conjunctival scrapings. Skin test is also often useful in detecting suspected allergens.

Allergic Conjunctivitis Differential Diagnosis

Allergic Conjunctivitis should be clearly differentiated from other similar diseases like

  • Infectious Conjunctivitis

Antihistamines and anti-inflammatory drops are directly put into the eye.

Nonsteroidal medicines such as Voltaren (diclofenac) ophthalmic solution and mast cell stabilizers like Alocril (nedocromil), Elestat (epinastine), Patanol (olopatadine) and Zaditor  (ketotifen) are quite useful in treating the symptoms of this disorder.

In acute stages, mild steroid drops may be administered on the eye surface for a brief duration under medical supervision.
