Conjunctivitis is a condition that is characterized by an inflammation of the conjunctiva, the thin filmy membrane that forms a lining around the front of the eye.

The disease is known as “Pink Eye”, “Sore Eyes” or “Bloodshot Eyes” in the US. It is one of the most common non-traumatic eye complaints around the world.

Conjunctivitis Types

Conjunctivitis is classified into eight types. These are :

Allergic Conjunctivitis

This variation of the disease is usually associated with other conditions like Allergic Dermatitis and Hay Fever. The symptoms begin to appear in early spring. Allergic Conjunctivitis generally gives rise to white, watery discharge from the eyes. It is not an infective disease but may occur in multiple members of the same family.

Bacterial Conjunctivitis

Like Allergic Conjunctivitis this disease may be acute or chronic. Bacterial conjunctivitis gives rise to yellow, greenish yellow or whitish yellow discharge from the eyes. The discharge accumulates in the eyes in the mornings. It is an infective condition and is usually associated with other disorders like Seborrheic Dermatitis, Purulent skin infections, upper respiratory infection, Rosacea and exposure of eyes to foreign bodies.

Viral Conjunctivitis

As the name suggests, this variation of Conjunctivitis is caused by virus infection. Adenovirus and Herpes Simplex Viruses are the common cause of Conjunctivitis. Acute cases of Conjunctivitis are frequently a result of infection by Coxsackievirus A24 and Enterovirus 70. The condition is highly infectious and results in watery discharge from the eyes. It is associated with fever, Upper Respiratory Infection and skin eruptions.

Chemical Conjunctivitis

This disorder results from exposure of eyes to strong chemicals as found in soaps, hair dyes and shampoos. It also arises from exposure to acids, toxins, irritants and caustic alkalis like Sodium Hydroxide.

Chlamydial Conjunctivitis

This condition is sub-acute and causes yellowish-white or white pus discharge from the eyes. This infective disorder results from infection by Chlamydia bacteria caused due to sexual contact with multiple partners, venereal diseases and Urinary Tract conditions.

Neonatal Conjunctivitis

It is a type of Bacterial Conjunctivitis contracted by newborns during delivery. It happens when the eyes of the infant are contaminated while passing through the birth canal of a mother infected with either Chlamydia trachomatis or Neisseria Gonorrhoeae. This is a very serious kind of Conjunctivitis. Neonatal Conjunctivitis untreated may lead to blindness.

Parasitic Conjunctivitis

This is a chronic, non-infectious disorder and gives rise to variable symptoms. It is caused by a parasitic infection and is associated with other diseases like Trichinosis, Leishmaniasis and Pediculosis.

Fungal Conjunctivitis

This chronic disorder is caused by fungal infection and is associated with HIV and Debilitation. Medical therapies such as Immunosuppressive Therapy and Chemotherapy may also cause this condition. It may also result from trauma to the eye from non-organic matter like leaves or sticks. In people with normal immunity, this is a non-infective condition.
