Dry eyes testing is crucial to understanding the extent of the dry eye condition, not to mention planning appropriate treatment. In fact, dry eyes testing before treatment involves a complete eye assessment.
The dry eyes testing process
Dry eyes testing requires a complete eye assessment. This includes a questionnaire and an appraisal of any medications used, as well as specialised optical imaging.
OSDI questionnaire
The OSDI (Ocular Surface Disease Index) questionnaire helps classify a patient’s dry eye symptoms. It is based on a scale of 0 to 100, with higher scores representing worse symptoms.
Medication appraisal
Optometrist appraise medications to determine whether or not they are contributing to dry eye symptoms.
Meibography
Meibography analyses the meibomian glands using an infrared camera. Indeed, it enables optometrists to determine if they are functioning correctly. So meibography is an invaluable tool in dry eye assessment and monitoring progress.
LipiView
The LipiView test measures the lipid (oily) layer of the tear film. In addition, it also measures the way a patient blinks using high speed imagery.
Phenol red thread test
The phenol red thread test determines whether the lacrimal gland is functioning properly, producing enough water to support tear film.
Vital Dyes
Dyes are used to highlight the ocular surface. Compromised areas on the front surface of the eyes show as discoloured.
Transillumination of the eye lids
A transillumination test determines whether a patient might be sleeping with their eyes slightly ajar at night. Indeed, this condition is easily missed so the transillumination test is very important.
Dry eyes testing at The Eye Practice
The Eye Practice is a recognised leader in dry eye testing as well as treatment. So if you suffer dry eyes, our team of optometrists are able to diagnose the extent of the problem and develop a tailored treatment plan.
