Aqueous Tear Deficiency and How Hartsdale Family Eyecare Can Help

We believe in offering personalized eye care that meets the individual needs of each patient. As part of this commitment to our patients, we offer treatment for symptoms of many forms of dry eye syndrome, including aqueous tear deficiency.

Healthy Tears and Aqueous Tear Deficiency

Tears are vital for maintaining eye health and clear vision. They consist of three layers: an outer oily layer, a middle watery (aqueous) layer, and an inner mucus layer. The aqueous layer is crucial for hydrating the eye, washing away debris, and protecting against infection. In healthy eyes, these layers work together to keep the eye’s surface smooth and clear.

Aqueous tear deficiency, a form of dry eye disease, occurs when your eyes don’t produce enough of the aqueous layer of your tears. Without sufficient watery tears, the eye’s surface can become dry and irritated, leading to discomfort and an increased risk of infections and damage to the corneal tissue.

What Causes Aqueous Tear Deficiency?

Unlike other forms of dry eye, aqueous tear deficiency is primarily related to a decrease in tear production, rather than an imbalance in tear composition. This can result from several factors. One of the most common causes is age-related decline in tear production, which affects both men and women, though it is more prevalent in postmenopausal women.

Autoimmune diseases such as Sjögren’s syndrome can also significantly reduce tear production, leading to chronic dry eye. Other contributing factors include certain medications, radiation therapy, and conditions that affect the lacrimal glands (which produce the aqueous component of tears).

Environmental factors can also exacerbate aqueous tear deficiency, including prolonged exposure to wind, smoke, and dry climates. Additionally, individuals who spend a lot of time staring at screens may blink less frequently, reducing the spread of tears across the eye’s surface and worsening dryness.

Symptoms of Aqueous Tear Deficiency

The symptoms of aqueous tear deficiency can range from mild to severe and often worsen over time if left untreated. Common symptoms include:

• Persistent dryness and irritation in the eyes
• A sensation of burning or stinging
• Redness and inflammation
• Sensitivity to light
• Blurred vision, particularly after prolonged reading or screen use
• A gritty or sandy feeling in the eyes

These symptoms can affect your quality of life, making everyday activities like reading, driving, or using a computer uncomfortable or even painful.

Diagnosis and Treatment

Diagnosing aqueous tear deficiency typically involves a comprehensive eye exam. Your eye care provider may perform tests to measure tear production, evaluate the quality of your tears, and examine the surface of your eyes for signs of dryness or damage. Identifying the underlying cause is also crucial for effective treatment.

Treatment options for aqueous tear deficiency vary based on the severity of the condition and the underlying cause. Common treatments include:

• Artificial tears: Lubricating eye drops can help supplement natural tear production.
• Prescription medications: These may be used to stimulate tear production or reduce inflammation.
• Punctal plugs: Tiny devices can be inserted into the tear ducts to prevent tears from draining away too quickly.
• Lifestyle modifications: Increasing humidity in your environment, taking breaks during screen use, and wearing protective eyewear can all help manage symptoms.

For more severe cases, your eye care provider may recommend advanced treatments like serum eye drops or surgical options.
