Understanding Dry Eye Disease
Dry Eye Disease (DED) is a common condition that occurs when the eyes do not produce tears properly or when the tears are not of the correct consistency and evaporate too quickly. At the core of this condition are two primary culprits:
Tear Film Abnormalities
Healthy vision depends on a stable tear film—a complex, three-layered structure composed of oils, water, and mucus. This film keeps the surface of the eyes adequately lubricated, nourished, and protected against infection. When any layer of the tear film is compromised, it can lead to tear instability and dry eye symptoms.
Meibomian Gland Dysfunction (MGD)
These specialized glands located in the eyelids secrete oils essential for preventing tear evaporation. Dysfunction of these glands can result in a deficient oily layer, causing tears to evaporate too rapidly—a condition known as Evaporative Dry Eye (EDE).
In addressing such dysfunctions, Perfluorohexyloctane (PFHO) has emerged as an innovative approach. PFHO is a water-free liquid with properties that mimic natural oils found in the tear film. When used in treatments like Nov03, it replenishes the lipid layer, thus offering relief from dry eye symptoms associated with MGD.
The role of the Food and Drug Administration (FDA) is pivotal in validating the safety and effectiveness of treatments for DED. FDA approval is based on rigorous evaluation processes and clinical trial data—ensuring that patients receive therapies that not only provide relief but also adhere to stringent quality standards. This endorsement is crucial for both healthcare providers and patients in choosing reliable options for managing dry eye disease. The best and top Optometrists in the industry are working hard to get new drops tested and FDA approved.
Common Types and Causes of Dry Eye Disease
Dry eye disease has two main forms: Evaporative Dry Eye (EDE) and Aqueous-Deficient Dry Eye (ADDE).
Evaporative Dry Eye (EDE)
EDE is the most common form, accounting for about 86% of dry eye cases. In EDE, the lipid layer of the tear film, which helps prevent tears from evaporating too quickly, is compromised due to a condition called Meibomian Gland Dysfunction (MGD). This leads to rapid tear evaporation and a condition known as tear hyperosmolarity.
Aqueous-Deficient Dry Eye (ADDE)
ADDE affects the remaining 14% of patients with dry eye disease. In this form, the lacrimal glands in the eyes do not produce enough tears, resulting in an inadequate amount of the watery component of tears.
Environmental factors can worsen both types of dry eye disease. Exposure to wind, smoke, or dry climates can increase tear evaporation rate and worsen symptoms. Additionally, spending long hours looking at digital screens can reduce blinking frequency and increase desiccating stress, which can contribute to EDE.
To avoid repeating information in future sections about specific treatments, we'll discuss potential solutions later in this guide. The next section will focus on one such solution: Restasis, including how it works and its effectiveness. A dry eye exam assessment with a qualified Optometrist in Calgary near you can help you identify which type of dry eye disease you have. Call our Eye Clinic in Southcentre Mall to book an appointment.
Restasis: Mechanism of Action and Effectiveness
Restasis, an FDA-approved treatment for chronic dry eye, utilizes cyclosporine to combat the condition's underlying issues. Cyclosporine is an immunomodulating agent that addresses ocular inflammation—one of the pivotal elements contributing to dry eye disease.
Cyclosporine's Role
Reduces Inflammation: By inhibiting certain immune cells that cause inflammation on the ocular surface, restasis decreases the chronic inflammation that can disrupt tear production and lead to dry eye symptoms.
Stimulates Tear Production: Beyond its anti-inflammatory properties, cyclosporine has been shown to increase lacrimal gland tear output, essential for maintaining a healthy and lubricated eye surface.
Clinical studies have been instrumental in assessing restasis' effectiveness. Key findings include:
Clinical Studies
Improved Tear Production: Research demonstrates that consistent use of restasis significantly improves tear production, as measured by Schirmer's test—a diagnostic tool for tear secretion.
Patient Symptom Relief: Studies report patients experiencing relief from the burning and itching associated with dry eye disease after starting restasis treatment.
Patient experiences reinforce clinical data, with many reporting a noticeable improvement in comfort and a reduction in dry eye symptoms over time. The therapy requires patience, as it may take several months for maximal benefits to manifest.
Patient Experiences
Long-term Benefits: Patients often describe a gradual improvement in dryness and comfort level with continuous use.
Adherence Importance: Success with restasis is closely tied to adherence to the prescribed treatment regimen.
Xiidra: Targeting Inflammation to Relieve Dry Eye Symptoms
Xiidra is a prescription eye drop solution used to relieve the signs and symptoms of dry eye disease. Its active ingredient, Lifitegrast, works by inhibiting the interaction of two proteins (LFA-1 and ICAM-1) involved in ocular surface inflammation. This action helps reduce the immune responses on the ocular surface that often contribute to dry eye disease.
The Role of Inflammation in Dry Eye Disease
Inflammation plays a crucial role in dry eye disease. It's not only a symptom but also a cause for this condition. When our eyes become dry, they get irritated, triggering an inflammatory response. This inflammation damages the tear-producing cells, leading to decreased tear production and perpetuating a cycle of dryness and inflammation.
The Potential Benefits of Xiidra
The potential benefits of using Xiidra as a treatment option are significant:
Anti-Inflammatory Action: By addressing inflammation at its source, Xiidra helps break the cycle of dryness and inflammation that characterizes dry eye disease.
Symptom Relief: Clinical trials have shown that Xiidra can significantly reduce both the signs (observable changes) and symptoms (patient-reported discomfort) of dry eye disease.
Rapid Onset: In some clinical trials, improvement in patient-reported symptoms was noted as early as two weeks after starting treatment.
By modulating immune responses on the ocular surface, Xiidra offers an effective way to manage dry eye disease—providing relief from symptoms while addressing one of its underlying causes: inflammation. Find the best Optometrist in Calgary for you to see if Xiidra is for you. A dry eye exam assessment near you will quickly identify your eligibility.
