What is it?
Dry eye syndrome is one of the most common issues that affect the general population. It is a condition characterized as the break down of the tear film, a natural layer of tears that coats the surface of the eye. The tear film's purpose is to prevent drying of the ocular surface, supply oxygen to nourish the surface epithelia, and host an immune system with its innate anti-microbials. The tear film's integrity is also an essential part of vision because it creates a smooth surface for light to enter the eye.
What is the tear film made of?
The tear film is made of lipid, water, and mucus layers. A disruption to any of the three layers can cause dry eyes.
What are common signs and symptoms?
- Blurry vision that can improve after blinking
- Scratchy, gritty, or foreign body sensation
- Watery or teary
- Red, stinging, or burning
- Discomfort when wearing contacts
What are the causes?
- Certain systemic conditions such as Sjogren's syndrome, thyroid disease, arthritis, and lupus
- Eyelid disorders such as blepharitis, meibomian gland dysfunction, and ectropion
- Looking at a computer for an extended period of time, or any activity that reduces blinking
- Being in a windy or dry environment such as airplanes
- Prior eye surgeries such as LASIK or PRK
- Certain medications such as for allergies, high blood pressure, depression, or sleep
What are the treatments?
The treatment for dry eyes is largely depending on its underlying cause. There are several tests your eye doctor can perform to determine the cause. Treatment options can range from over-the-counter eye drops to prescription eye drops and procedures performed in-office.
