Conjunctivitis

Conjunctivitis

Also known as pink eye, conjunctivitis infective, contagious ophthalmia

Overview

Conjunctivitis is an infection of conjunctiva, a transparent membrane that lines the eyelid and covers the white part of your eyeball. When small blood vessels in the conjunctiva become inflamed, they become more prominent. This is what causes the whites of your eyes to appear reddish or pink, hence the name pink eye.


Conjunctivitis is marked by burning and itching in the eyes along with mucus or pus discharge. There is a constant urge to rub the affected eye and in some cases pain may also be present. It may be caused due to certain infectious agents such as viruses, bacteria or non-infectious causes such as dust, fumes or other allergens. Diagnosis is usually confirmed by physical examination by your doctor and treatment depends upon the infective cause of the condition. While viral conjunctivitis does not require any treatment, bacterial infection may require anti-infective agents in the form of eye drops or ointments.

You can prevent conjunctivitis by keeping your hands clean and avoid sharing personal belongings such as eyewear, eyedrops, makeup with infected individuals. Cautious use of contact lenses is also important to prevent contracting this infection. Conjunctivitis, which gets worse with each passing day, should be taken seriously and treated by an ophthalmologist as it poses a risk of complications such as uveitis and corneal perforation.

Symptoms Of Conjunctivitis

Conjunctiva refers to the mucous membrane that covers the outer surface of your eyes and is responsible for maintaining a healthy eye and vision. Conjunctivitis refers to the inflammation and infection of the conjunctiva. You may suspect conjunctivitis if you have: 

  • Pink or red color in the white of the eyes

  • Burning, irritation or itching in the eyes

  • Discharge of mucus or pus from the eyes

  • Swelling of the layer lining the white part of the eye and the eyelid(inside part of the eyelid)

  • Increased production of tears

  • A constant feeling of a foreign object in your eyes

  • A constant urge to rub your eyes

  • Thick mucous discharge that crusts over of lashes especially after waking up making the eye difficult to open

  • Pain and tearing in eyes

  • Increased sensitivity to light

Eye pain, medically known as ophthalmalgia, is a common complaint that causes discomfort in and around the eyes. Here are common causes of eye pain. 

Causes Of Conjunctivitis

Conjunctivitis may be caused by pathogens such as bacteria,viruses or some allergens and irritants. Some of the most common causes of conjunctivitis are described below:

1. Infectious causes of conjunctivitis

These types of conjunctivitis are contagious ie. They can easily spread from an infected person or by something an infected person has touched, such as a used tissue. The various types of infectious causes are as follows:

  • Bacterial conjunctivitis is very common in children and some of the common bacterias responsible for conjunctivitis are Staphylococcal species such as Staphylococcus aureus, H. influenza, S. pneumoniae, and Moraxella catarrhalis. Bacteria such as Streptococcus pneumoniae and Haemophilus influenzae cause conjunctivitis in adults.

  • Viral conjunctivitis is also quite common in adults. This type of conjunctivitis is very contagious and often spreads in schools and other crowded places. Viruses such as Adenoviruses, Herpes simplex, Herpes zoster, and Enterovirus are known to cause conjunctivitis.

2. Non-infectious causes of conjunctivitis

These conjunctivitis are not contagious and are usually caused by some allergen or irritant:

  • Allergic conjunctivitis is the body's reaction to allergens or allergic substances. It affects both eyes and is a response to an allergy causing substance such as pollens, dust mites, molds, dander from pets, medicines or cosmetics etc. Allergic conjunctivitis is more common in people with other allergic conditions, like hay fever, asthma, and eczema. One may also experience symptoms like sneezing and watery nasal discharge along with symptoms of conjunctivitis.

  • Giant papillary conjunctivitis is a type of allergic conjunctivitis caused by the long term presence of a foreign body in the eye. People who wear inflexible contact lenses, use soft contact lenses that are not changed frequently or have a prosthetic eye are more prone to develop this kind of conjunctivitis.

  • Irritant conjunctivitis is caused by irritants like smoke, dust, fumes. Toxins like chemicals from the chemical industry or the chemicals/gases used in a laboratory or caustic materials like bleach can cause conjunctivitis and in some cases a chemical splash can lead to permanent damage to the eye as well.

Risk Factors Of Conjunctivitis

You are at a high risk of contracting conjunctivitis if you:

  • Are exposed to people who are infected with conjunctivitis

  • Share items such as towels, pillow cases, makeup products with the infected individual

  • Have sinusitis

  • Have certain immunodeficiency diseases, trauma, other eye diseases and exposure to congenital sexually transmitted disease increases your risk of this condition

  • Wear contact lenses for extended hours particularly during their sleep which put you at a high risk of bacterial corneal infection

Did you know?
Pinkeye in newborns/neonatal conjunctivitis/ophthalmia neonatorum is a severe form of conjunctivitis that occurs in newborn babies or within the first month after birth. If a pregnant woman is suffering from a sexually transmitted disease like chlamydia or gonorrhea, the infant is exposed to them during delivery. It is a serious condition that could lead to eye damage. In such a case, consult the child's pediatrician or ophthalmologist for timely treatment under expert guidance.

Diagnosis Of Conjunctivitis

Conjunctivitis is usually confirmed by a physical examination by your eye doctor or ophthalmologist. 


Lab tests such as eyelid cultures are rarely performed. Eyelid cultures are usually carried out when you are facing recurrent infections of conjunctivitis or the infection is not getting better with medications. In certain cases an RT-PCR test may be advised for conjunctivitis caused by the viruses.

Treatment Of Conjunctivitis


The treatment of conjunctivitis depends on the cause of the symptoms. There are mainly three types of conjunctivitis namely viral, bacterial and allergic conjunctivitis. Different treatment options for these types of conjunctivitis are as follows:

1. Antibiotics

These are effective against bacterial conjunctivitis which causes red and itchy eyes. These can be given either in drops, ointment or oral form. Example of this class of drugs include:

2. Corticosteroids

These are mostly prescribed to relieve conjunctivitis caused due to an allergen such as dust or irritant. It is also used to ease inflammation as well as pain due to the infection. Some of the commonly prescribed steroids for conjunctivitis include: 

3. NSAIDs

As conjunctivitis can cause pain in the eyes along with redness and swelling, painkillers such as non-steroidal anti-inflammatory drugs (NSAIDs) are commonly recommended to get rid of pain as well as inflammation in the eyes. Your doctor may recommend ophthalmological NSAIDS such as ketorolac.


Note: For viral conjunctivitis, you just need to use cold compress. It usually does not respond to the antibiotic treatment and runs its course before it starts getting better.

Stop taking antibiotics for every common health problem
Antibiotics are the common medicines which are used to treat various health problems like running nose, stuffed-up head, and the annoying cough, which is not good. Antibiotics are the medicines that are effective only for bacterial infections and not viral infections. Here’s more on when to take and when not to take antibiotics.

Home-care For Conjunctivitis

  • Wash your personal belongings such as bedsheets, pillowcases, sheets, washcloths, and face towels with hot water and detergent; Make sure to clean your hands after you handle these items.

  • Do not wear contact lenses until your ophthalmologist advises you to start wearing them again.
