As intriguing as it may seem, our eyes communicate more than just emotion. They provide us with essential clues about our overall health. Two common yet contrasting conditions — dry eyes and excessive tearing — serve as perfect examples. Understanding these conditions can help us decode what our eyes are trying to tell us, paving the way for timely intervention and treatment.

In this post, we’ll delve into these two eye conditions, exploring their causes, symptoms, and potential treatments. By the end of this read, you’ll be better equipped to listen when your eyes start talking.

Understanding the Eye’s Tear System

The human eye is an intricate organ, and its tear system plays a crucial role in maintaining optimal vision and overall eye health. Comprehending this system can help us understand conditions such as dry eyes and excessive tearing.

The tear system, also known as the lacrimal functional unit, comprises the lacrimal glands, conjunctiva, and the eyelids’ edges. The lacrimal glands, located above each eye, produce tears, while the conjunctiva, a thin tissue layer covering the white part of the eyes, aids in tears spread across the eye surface during blinking. The eyelids’ edges contain tiny drain openings that allow tears to flow into small channels (canaliculi) and further into the lacrimal sac before draining into the nose.

Tears are not merely water; they are a complex mixture of water, fatty oils, proteins, electrolytes, and bacteria-fighting substances. This composition helps keep the eye surface smooth and clear, lubricates the eyes, prevents infection, and heals eye surface wounds.

In a healthy tear system, tear production and drainage are balanced, providing just enough moisture for the eyes. However, disruptions to this balance can lead to dry eyes or excessive tearing. Understanding these conditions requires an in-depth look at their symptoms, causes, and potential treatments, which we will discuss in the following sections of this blog.

Symptoms and Causes of Dry Eyes

Dry eyes are a common condition affecting many people worldwide. They occur when your tears aren’t able to provide adequate lubrication for your eyes.

Symptoms

The symptoms of dry eyes vary from person to person, but they generally include:

• A stinging, burning or scratchy sensation in your eyes
• Sensitivity to light
• Red eyes
• A feeling of having something in your eyes
• Difficulty wearing contact lenses
• Difficulty with nighttime driving
• Watery eyes, which is the body’s response to the irritation of dry eyes
• Blurred vision or eye fatigue

Causes

Dry eyes can be caused by a variety of factors, including:

• Age: Dry eyes are a part of the natural aging process. The majority of people over age 65 experience some symptoms of dry eyes.
• Gender: Women are more likely to develop dry eyes due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause.
• Medications: Certain medicines, including antihistamines, decongestants, blood pressure medications and antidepressants, can reduce tear production.
• Medical conditions: People with rheumatoid arthritis, diabetes and thyroid problems are more likely to have symptoms of dry eyes.
• Environmental conditions: Exposure to smoke, wind and dry climates can increase tear evaporation resulting in dry eye symptoms.

Understanding the symptoms and causes of dry eyes is the first step towards finding an effective treatment and relief from the discomfort.

Treatment Options for Dry Eyes

Dry eyes can cause significant discomfort and interfere with daily activities, but several treatment options are available. Here’s a look at the most common ones:

Over-the-Counter Treatments

• Artificial tears: These eye drops act as a supplement to natural tears, providing temporary relief from dry eye symptoms.
• Ointments and gels: These thicker lubricants provide longer-lasting relief but may blur vision temporarily, so they’re often recommended for use before bedtime.

Prescription Treatments

• Anti-inflammatory drugs: Eye drops such as cyclosporine (Restasis) or lifitegrast (Xiidra) can help your body produce more tears by reducing inflammation around the tear glands.
• Steroid eye drops: These can help reduce inflammation in the short term. Long-term use is typically avoided due to potential side effects.

Procedures

• Punctal plugs: Tiny silicone plugs can be inserted into the tear ducts to prevent tears from draining away too quickly.
• Intense pulsed light therapy: This procedure uses light pulses to liquefy and release hardened oils that have clogged glands in the eyelids.

Lifestyle Changes

• Blink regularly: Especially when reading or staring at a computer screen for long periods.
• Stay hydrated: Drink plenty of fluids to help maintain overall body hydration, including tear production.

Always consult with your eye care professional before starting any new treatment for dry eyes. They can recommend the best options based on your specific symptoms and causes.

Symptoms and Causes of Excessive Tearing

Excessive tearing, also known as epiphora, is a condition where tears overflow from your eyes without any apparent reason. This can be just as disruptive as dry eyes, causing blurred vision and discomfort.

Symptoms

The primary symptom of excessive tearing is an overflow of tears, which can lead to:

• Constantly watery eyes
• Blurred vision
• Redness and irritation
• Sensitivity to light
• Eye infections due to constant moisture

Causes

The causes of excessive tearing can be varied and include:

• Blocked tear ducts: Tears normally drain into your nose through tiny openings in the corners of your eyes. If these ducts are blocked, tears can’t drain properly leading to an overflow.
• Dry eye syndrome: It may seem contradictory, but dry eyes can actually trigger the overproduction of tears as a reflex response.
• Allergies or eye infections: These conditions can cause inflammation, leading to increased tear production.
• Wind, cold, or bright light exposure: These environmental factors can stimulate tear production.

Understanding the symptoms and causes of excessive tearing can help you identify when professional help is needed. If you’re experiencing persistent or severe symptoms, it’s important to seek advice from an eye care professional who can provide appropriate treatment options.

Remedies and Treatments for Excessive Tearing

Excessive tearing can interfere with your daily activities, but there are several remedies and treatment options that can help manage the symptoms.

Over-the-Counter Solutions

• Artificial tears: These can help lubricate your eyes and may reduce excessive tearing caused by dry eye syndrome.
• Antihistamine eye drops: If allergies are causing your excessive tearing, over-the-counter antihistamine eye drops may provide relief.

Prescription Treatments

• Antibiotics: If your excessive tearing is due to an eye infection, you may need prescription antibiotic drops or ointment.
• Steroid eye drops: If allergies are the cause, a doctor may prescribe steroid eye drops to reduce inflammation.

Surgical Procedures

• Dacryocystorhinostomy (DCR): If a blocked tear duct is causing excessive tearing, your doctor may recommend a DCR. This procedure creates a new route for tears to drain from the eye.

Lifestyle Changes

• Avoid irritants: Smoke, wind, and bright light can all stimulate tear production. Wearing sunglasses can help protect your eyes.
• Maintain good eye hygiene: Regularly clean your eyelids to avoid infections that could lead to excessive tearing.

Always consult with your eye care professional if you’re experiencing persistent symptoms of excessive tearing. They can guide you on the most suitable treatment options based on the specific cause of your condition.

When to Seek Medical Advice for Eye Conditions

While minor symptoms of dry eyes or excessive tearing can often be managed with over-the-counter treatments and lifestyle adjustments, it’s important not to ignore persistent or severe signs. These could indicate a more serious underlying condition that requires professional medical attention.

If you’re experiencing relentless dryness, burning, redness, or a feeling of grittiness in your eyes, these could be signs of chronic dry eye syndrome. Likewise, if your eyes are constantly watering, and you have blurred vision or discomfort, you may be dealing with excessive tearing. In both cases, if symptoms persist or interfere with your daily activities, it’s time to seek medical advice.

Eye conditions can sometimes be indicative of other health problems too. For instance, dry eyes can be associated with rheumatoid arthritis, lupus, and other autoimmune disorders. Similarly, blocked tear ducts might be a sign of a tumor pressing on the tear drainage system.
