My eye has been weeping for several weeks. The chemist recommended hypromellose 0.3% drops. My eye now gets gungy at night. What should I do?

There are several possible causes of weeping from the eye and for some people hypromellose can be useful for lubricating the eye. However, these have not solved the problem for you and anyone suffering with persistent watering eyes should visit their GP.

The most likely cause of dry eyes is something called meibomian gland dysfunction (MGD). This is where the glands in the eyes are not functioning properly.

The glands usually produce an oily substance that slows down the evaporation of tears between blinks. Without the oily substance the eyes become dry and sore and extra tears are produced to compensate for this.

If this is the cause, lubricating eye drops are usually used and it can also help to hold a clean and warm, damp cloth over the eye for 5 minutes whilst gently massaging the cloth over the eyelids. This can help to remove any substances that may be blocking the glands.

Other possible causes are infection, allergy, blocked tear ducts, lower eyelids that sag away from the eyes (ectropion) or eyelids that roll inwards (entropion).

We would suggest that you make an appointment with your GP so that they can make a diagnosis for you.
