Dry eye test
If your treatment for dry eyes isn’t working, it may be that the underlying causes have been misdiagnosed.
Successful treatment depends on a full understanding of all the factors at play in your dry eye condition. Accurate testing prior to treatment involves a complete dry eye assessment. It will include the following:
This has been validated after extensive study to classify and individuals symptoms consistently and reliably. Give yourself a head start by getting the results of this test even before you see us.
Medication and Previous History
We often find that medications and inappropriate use of eye drops can contribute to the overall dry eye picture.
This is a 20 second video clip of your blinking habits and a measurement of the lipid (oily) layer of your tear film. It provides over 600 images of your eyes in various stages of blinking so we can determine what rehabilitation is required. Recent studies have demonstrated that over 80% of dry eye suffers have some sort of meibomian gland dysfunction, which is also known as MGD. The meibomian glands are responsible for producing the oil in our tear film.
Phenol Red Thread Test
This allows us to determine whether your lacrimal gland is functioning properly and producing enough water to support the tear film.We prefer it to the older Schirmers test which most patients find very tedious and often painful. The Phenol Red Thread test takes less than 20 seconds and is painless.
This images and allows analysis of the meibomian glands using an infrared camera. Over 80% of dry eye occurs due to meibomian gland dysfunction. meibography is therefore an invaluable tool in assessment and monitoring progress.
Transillumination of the eye lids
Allows us to determine whether you might be sleeping with your eyes slightly ajar at night. This condition is commonly missed and is very important to treat. Sleeping with your eyes slightly open is also called nocturnal lagophthalmos and if not diagnosed all treatments will probably fail in the long run.
These are used to highlight the ocular surface. Fluorescein and Lissamine Green are used. Compromised areas of the front surface of the eyes can be discovered, which in turn allow us to determine what treatments are most likely to improve your condition.
Manual Expression of Meibomian Glands
Gentle pressure is applied to determine the resistance of these most important glands in our eyes.Occasionally it is a cost effective way of maintaining the function of the meibomian glands and keeping meibomian gland dysfunction at bay.
