Understanding Dry Eye (Keratoconjunctivitis Sicca)

Eye careCase Study
Written By Lucinda Howard

Dry eye, also known as keratoconjunctivitis sicca or simply dry eye syndrome, is a common eye condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to uncomfortable symptoms, including eye irritation, burning, itching, redness, and blurred vision. In severe cases, dry eye can also cause damage to the cornea, the clear dome-shaped surface that covers the front of the eye.

The tears produced by the eyes serve a vital function in maintaining eye health and comfort. They provide lubrication, help to clear away debris and foreign particles, and contain important proteins and nutrients that nourish the eye's surface. When the eyes do not produce enough tears or when the tears are of poor quality, the eyes can become dry and irritated.

There are many factors that can contribute to dry eye syndrome, including ageing, hormonal changes, certain medications, environmental factors such as dry or windy conditions, and underlying medical conditions such as autoimmune disorders or diabetes. Some people are also more prone to dry eye due to genetic factors.

Treatment for dry eye depends on the severity of the condition and the underlying causes. Mild cases of dry eye may be treated with over-the-counter artificial tears or lubricating eye drops that help to moisturize the eyes. In more severe cases, prescription medications or procedures may be necessary. For example, anti-inflammatory medications may be prescribed to reduce inflammation in the eye, or punctal plugs may be inserted to help prevent tears from draining too quickly.

In addition to medical treatments, there are also several lifestyle changes that can help to alleviate dry eye symptoms. These include avoiding exposure to dry or windy conditions, taking frequent breaks when working on a computer or reading, and using a humidifier to add moisture to the air. It is also important to maintain good overall health, including staying hydrated and eating a healthy diet rich in omega-3 fatty acids, which are essential for eye health.

If you are experiencing symptoms of dry eye, it is important to see an eye doctor for a proper diagnosis and treatment plan. With the right care and management, dry eye can be effectively managed, allowing you to maintain healthy and comfortable eyes for years to come.
