Millions suffer from dry eye, a condition that can lead to significant discomfort and, in some cases, a debilitating sensitivity to sunlight. Dr. Martin Scurr explains that these two issues are often linked and can be addressed with a simple, consistent treatment.
Dry eye commonly results from blockages in the meibomian glands, which are responsible for producing the oily outer layer of tears that lubricates the eyes. As individuals age, the number of these glands can decline, and their oil can become thicker, exacerbating dryness and potentially leading to inflammation and sore eyelids. In severe cases, such as that of a patient named Mrs. P. Tomkins, tiny plugs can be inserted into tear ducts to reduce tear fluid drainage.
Medications like Ikervis drops can help suppress inflammation, while lubricants such as Clinitas and Xailin ease symptoms. However, the associated light sensitivity, or photophobia, is believed to stem from the exposed eye surface due to reduced tear protection, making the nerves more reactive.
Dr. Scurr suggests that the underlying cause of dry eye, and by extension light sensitivity, can be treated with heat. Applying a warm compress, such as a flannel or a microwaveable eye mask, for ten minutes once or twice daily can help soften the thickened oil in the meibomian glands, promoting their release and alleviating symptoms.
While lutein supplements are sometimes suggested, Dr. Scurr clarifies that they are intended to protect the macula, the central part of the retina responsible for sharp vision, rather than directly treating dry eye or light sensitivity.
