excessive tearing

Excessive tearing, also known as epiphora, is a condition characterized by an overflow of tears onto the face [10]. It can be caused by various factors and can be a source of discomfort and inconvenience for individuals [12].

There are two main categories of epiphora: overproduction of tears or inadequate drainage of tears [15]. Overproduction of tears occurs when the eyes produce more tears than they can drain, leading to an overflow of tears onto the face. Inadequate drainage of tears, on the other hand, occurs when the tear ducts are blocked or narrowed, preventing the normal flow of tears away from the eye.

Common causes of excessive tearing include allergies [9], dry eyes [6][7], inward or outward turning of the eyelids [9], as well as infection, narrowing, or blockage of the tear ducts [9]. Other possible underlying health issues that may cause excessive tearing include upper respiratory infections, allergic rhinitis, and eye infections [14].

Symptoms of epiphora can vary depending on the underlying cause, but common symptoms include pain, redness, blurred vision, sensitivity to light, and excess tearing and white discharge [11]. If left untreated, epiphora can lead to further complications such as conjunctivitis or corneal ulcers.

It's essential to consult a healthcare professional for proper diagnosis and treatment of excessive tearing. They will assess the individual's symptoms and medical history to determine the underlying cause of the condition and recommend appropriate treatment options [1].

Excessive tearing, also known as epiphora, can manifest in various ways, making it a bothersome condition for many individuals. Some common signs and symptoms include:

• Blurred vision: Excess tears can cause the eyes to become watery, leading to blurred or hazy vision [9].
• Glassy-looking eyes: The constant production of tears can give the eyes a glassy or shiny appearance [7].
• Sore skin around the eyes: Constantly wiping away excess tears can cause irritation and soreness on the skin around the eyes [9].
• Redness and inflammation: Excessive tearing can be accompanied by redness, swelling, itching, and other signs of eye surface inflammation [3].
• Eye irritation or pain: Some individuals may experience discomfort or pain in their eyes due to excessive tearing [4].

These symptoms can vary depending on the underlying cause of the excessive tearing. It's essential to consult a healthcare provider if you're experiencing prolonged or severe symptoms.

Excessive tearing, also known as epiphora, can be diagnosed through various tests to determine its underlying cause. Here are some diagnostic tests that may be performed:

• Schirmer's test: This test measures the amount of tears produced by placing a small strip of filter paper under the lower eyelid for 5 minutes. The results indicate whether the eye produces enough tears to keep it moist [1].
• Epithelial staining test: This painless test involves administering a drop into each eye to diagnose dry eye syndrome, which can be a cause of excessive tearing [7].
• Schirmer test with a large amount of wetting: A Schirmer test with a large amount of wetting (e.g., > 25 mm) suggests an evaporative dry eye as the etiology of tearing [3].
• Physical Exam: A thorough physical examination by an ENT doctor, including inspection of the eyes and questioning about symptoms, is also essential for diagnosis [5].
• Imaging tests: X-ray, computerized tomography (CT), or magnetic resonance imaging (MRI) may be used to find the location and cause of a blockage in the tear ducts [6].
• Tear quality test: A thread filled with pH-sensitive dye is placed over the lower eyelid, wetted with tears for 15 seconds, and then measured for tear volume to determine the quality of tears [13].

These diagnostic tests help identify the underlying cause of excessive tearing, which can be due to an overproduction of tears or inadequate drainage. A thorough evaluation by a healthcare professional is necessary to determine the most appropriate treatment plan.

Excessive tearing, also known as epiphora, can be treated with various medications depending on its underlying cause.

• Antibiotic drops: If an infection is causing the epiphora, antibiotic drops may be prescribed by an ENT specialist to treat the underlying infection [4].
• Artificial tears: Doctors sometimes recommend the use of artificial tears to decrease watery eyes when dry eyes or eye surface irritation is the cause [8].
• Anti-allergy medications: If allergies are the cause of excessive tearing, anti-allergy medications may be prescribed to alleviate symptoms [6].

In some cases, medication may not be sufficient to treat epiphora, and other treatments such as removing foreign objects, clearing blocked tear ducts, or repairing eyelids may be necessary [5]. It's essential to consult a physician or eye doctor for proper diagnosis and treatment.

The differential diagnosis for excessive tearing, also known as epiphora, involves identifying the underlying causes of this condition.

• Increased production or outflow obstruction: This is a common cause of excessive tearing, where the eyes produce too many tears or there is an obstruction in the tear ducts [5].
• Encephalocele: A rare congenital anomaly where there is a protrusion of the brain tissue through a defect in the skull, which can lead to excessive tearing [6].
• Blocked tear duct: A blockage in the tear ducts can cause tears to accumulate and overflow, leading to excessive tearing [4].
• Dry eyes: Drying of the eyes can also cause an increase in tear production, leading to excessive tearing [8].

It's worth noting that in many patients, the cause of excessive tearing can be multifactorial, involving a combination of these factors.
