Conjunctivitis ​

The conjunctiva is a thin layer of clear tissue that lies over the white part of the eye and lines the eye lids. It also contains small blood vessels. When these vessels become inflamed, the eye appears red, hence explaining why the disorder is called ‘pink eye’. Conjunctivitis is a common disorder in children, teachers and day-care workers because they are more likely to be exposed to someone infected with conjunctivitis. 

Conjunctivitis may be caused by a viral infection, bacterial infection, allergies, or exposure to a foreign object. It may affect one or both eyes, and is a very contagious disorder which can spread if one comes in direct or indirect contact with discharge from the eyes of an infected person. Owing to its contagious nature, it is better if conjunctivitis is detected earlier so that treatment can be started, helping prevent the spread of this disease. 

Although conjunctivitis may be frightening for some because of uncomfortable symptoms, such as red eyes and thick, greenish discharge, it is rarely harmful for your vision. However, conjunctivitis in new-born babies – neonatal conjunctivitis – can be a serious complication if left untreated. Therefore, any signs of conjunctivitis in new-borns should be immediately examined by an eye doctor.

When to seek expert advice

​​Even though conjunctivitis is not harmful to your vision, it must be treated as soon as you identify signs of this disorder since it is extremely contagious. Therefore, if you develop the symptoms of pink eye described above, you must make an appointment with an ophthalmologist (eye specialist) working with the Department of Ophthalmology and Visual Sciences at The Aga Khan University Hospital to get your symptoms assessed. This can help prevent the spread of the infection to those around you. 

Pink eye must especially not be ignored in new-borns as delayed treatment can lead to further complications. Any disturbances in your vision are also a cause for concern and require assessment by a doctor.​
