Dry Eye Facts
What is the estimated population of USA that suffers from dry eye condition?
The estimated population of the United States that suffers from dry eye condition varies. Here are some estimates mentioned:
- The Dry Eye Assessment and Management Study Research Group estimated that more than 16 million US adults have diagnosed Dry Eye Disease (DED) [3].
- An estimated 16-49 million Americans have dry eyes, which accounts for 5-15% of the population.
- A meta-analysis of three United States studies estimated a pooled prevalence of dry eye of 8.1 percent.
- It is also mentioned that the prevalence of dry eye increases with age and is higher among women than men.
Please note that these estimates may not be precise and can vary depending on the study methodology and criteria used to define dry eye. It’s always best to consult with a healthcare professional for accurate and up-to-date information on the prevalence of dry eye in the United States.
Who is affected by dry eyes (age groups, occupations, different disease states that cause dry eyes)
Dry eye disease (DED) is a multifaceted ocular surface condition marked by an imbalance of the tear film.
This disease can be broken down into two types:
- Evaporative dry eye disease is a common ocular condition characterized by an imbalance in the composition of the tear film, primarily due to issues with the meibomian glands that produce the protective lipid layer of tears. When these glands become dysfunctional, it can lead to increased tear evaporation and discomfort. Symptoms often include burning sensations, gritty feelings, and fluctuating vision. Effective management typically involves treatments aimed at restoring the function of the meibomian glands, such as warm compresses, lid hygiene, and in some cases,
specialized therapies like LipiFlow®. Understanding and addressing evaporative dry eye is crucial for maintaining clear and comfortable vision.
- Aqueous-deficient dry eye is characterized by insufficient production of the watery component of tears. Aqueous dry eye can result from various factors, including age, autoimmune disorders, medication side effects, and certain medical conditions. Individuals with this condition often experience symptoms like persistent dryness, irritation, redness, and blurred vision. Effective management typically involves the use of artificial tears and prescription medications to stimulate tear production. Proper diagnosis and treatment are crucial for relieving discomfort and maintaining eye health.
Dry Eye Disease affects individuals across the age spectrum, from young to elderly populations. In today’s digital age, DED is increasingly prevalent in younger demographics due to prolonged screen use, which reduces blink rates and increases tear evaporation.
Many surgical procedures can also worsen the condition. Post-cataract and post-blepharoplasty (eyelid surgery) patients might experience temporary dryness as their eyes heal from surgical trauma.
In essence, dry eye disease can arise from various sources, be it systemic health conditions or environmental factors, emphasizing the importance of proactive eye care and management for those at risk.
