DRY EYES

Tears normally coat the surface of the eyes to keep them moist comfortable. When tears are poor in quantity or quality, it cause dry eyes. Dry eyes usually present with gritty sensation, burning, redness and discomfort in the eyes. Ironically watering of eyes is also a symptoms of dry eyes. This occurs because the dry surface of the eyes stimulates the nerves to reflexly cause tearing.

Normally when we blink, the eyelids close and replenish the normal tear film by draining away the old tear film. Also on blinking, around 30 to 40 glands located in the eyelids secrete oily secretions to stabilize the tear film. The average blink rate in an infant is around 8 to 12 blinks a minute and as we age the blink rate drops to around 4 to 6 blinks per minute. In between blinks, when the eye remains exposed to the atmosphere, the tear film dries up resulting in symptoms of dry eyes.

When viewing any object with interest, subconsciously the blink rates further decrease to 1 to 2 time a minute. This results in poor blinking or habitual “half blinking”. This worsens symptoms of dry eyes and also retains the secretions of the glands. This is called Meibomian Gland Dysfunction. This accounts for 86% of the causes for dry eyes.

Normally, our eyes are comfortable looking down to read a book, than to look at a computer monitor at or above the eye level exposing more surface area of the eye to the atmospheric environment contributing to dry eyes. In an air conditioned environment, the eyes dry up faster.

Computer users are prone to dry eyes due to prolonged hours of usage. It is mandatory that all computer users are evaluated for dry eyes and Meibomian gland dysfunction.

General treatment of dry eyes is with lubricating eye drops and warm compresses to provide relief. This is only a temporary measure.

With recent advances in technology, it is now possible to image individual glands with high end infra-red cameras to determine its function. The device LIPISCAN also gives an information about the viability of the glands.

The LIPIFLOW is the most modern and efficient technique to manage dry eyes. It is a simple procedure lasting only 12 to 15 minutes done on a day care basis. The LIPIFLOW provides controlled pressure and heat impulses to the eyelids to relieve Meibomian gland dysfunction.

This exciting treatment is available at Uma Eye Clinic for the first time in Tamil Nadu! It is possibly the only treatment available for evaporative dry eye. LIPIFLOW is a very effective yet simple procedure for individuals with dry eye.

This procedure does not need admission. It takes only 12 minutes. All normal routine activities can be resumed immediately after the procedure. The results are promising and the advent of this technology appears as a bliss to individuals with dry eye disorder.
