What Is Dry Eye Syndrome?

Go to Our Treatment Page

Dry eye syndrome is a chronic eye disease characterized by the eyes inability to produce quality tears to lubricate the eye or the tears are not properly absorbed. Dry eye syndrome has many symptoms, one of which is tearing. This symptom may be confusing to patients as a symptom of dry eye because one may excessive tearing  is contradictory to dryness. However, when the eye is dry it begins to generate an excessive amount of tears to help restore moisture, unfortunately the tears are not an adequate pH quality.

Dry eye syndrome is the most common eye disease effecting 5-6% of the population and up to 6-10% of post-menopausal women. That number increases to 36% in elderly individuals.

Dry eyes, also known as dry eye syndrome or keratoconjunctivitis sicca, is a condition where the eyes do not produce enough tears or the tears evaporate too quickly. This leads to discomfort, irritation, and in some cases, inflammation of the eyes. Common symptoms of dry eyes include:

1. Stinging or burning sensation: The eyes may feel like they are burning or stinging.
2. Grittiness or feeling of a foreign body: It can feel like there is something gritty or a foreign object in the eye.
3. Redness: The eyes may appear red or bloodshot.
4. Blurry vision: Vision may become temporarily blurry, especially during activities that require prolonged visual concentration such as reading or using a computer.
5. Sensitivity to light: Also known as photophobia, sensitivity to light may increase.
6. Watery eyes: Paradoxically, dry eyes can sometimes cause an overproduction of tears in response to the irritation.

Causes of dry eyes include aging, hormonal changes, environmental factors (like dry climates or air conditioning), certain medications, and underlying health conditions such as autoimmune diseases. Management typically involves using artificial tears, addressing underlying causes, and in some cases, using prescription medications or procedures to help improve tear production and reduce symptoms.

How is Dry Eye Diagnosed?

Determining whether you suffer from dry eye syndrome and determining the severity of the condition can be measured a number of ways. A comprehensive examination of your overall health and examination of the cornea is generally the first step to determining if a patient suffers from dry eye syndrome.  Once diagnosed, there are several treatment options considered depending on the severity of the condition.

TearLab Osmolarity System

The TearLab Osmolarity System is the first objective and quantitative test for diagnosing and treating patients with dry eye syndrome. This system provides fast and accurate results that only requires a small amount of tear film to diagnose dry eyes. Tearlab then generates an osmolarity number using a scale from normal, mild, moderate, to severe ,that gives accurate interpretation to the level of severity of your dry eye condition.

The osmolarity number provides Dr. Skouras with the best options for treatment, often eliminating the redundant preliminary diagnostic therapy associated with dry eye treatment in patients with severe dry eyes, and allowing treatment with more aggressive treatment options sooner. This allows Dr. Skouras to intervene early in the disease process and  provide customized treatment options for individual care.

Once Dr. Skouras has evaluated your osmolarity number and provided you treatment options, a follow-up visit will be provided. Upon this visit, your tear osmolarity will be measured again providing Dr. Skouras with accurate results on your response to that treatment.

Schirmer’s Test

Additionally, A Schirmer’s test measures basic tear function. This test involves inserting paper test strips under the lower eyelids for a short duration of time. Once the paper is removed, the tear secretion on the paper is measured and can provide information on the severity of dye eye.
