Puncta pruritica is a term used to describe itching or irritation around the tear ducts or the corners of the eyes. While it may sound complicated, we’re here to break down this condition in simple terms. In this article, we will explore the types, causes, symptoms, diagnostic tests, treatments, and drugs associated with puncta pruritica.
Types of Puncta Pruritica:
Puncta pruritica can be categorized into two main types:
- External Puncta Pruritica: This occurs when the itching and irritation are on the outer part of the eye, often near the corners.
- Internal Puncta Pruritica: In this type, the discomfort is felt inside the eye near the tear ducts.
Now, let’s delve into what can cause this irritating condition.
Causes of Puncta Pruritica:
- Allergies: Allergic reactions to pollen, dust, or pet dander can lead to itchy eyes.
- Dry Eye Syndrome: Inadequate tear production can cause eye irritation.
- Eye Infections: Bacterial or viral infections of the eye can result in itching.
- Conjunctivitis (Pink Eye): Inflammation of the conjunctiva can lead to itching and redness.
- Contact Lenses: Improperly cleaned or ill-fitting contact lenses can irritate the eyes.

- Systemic Diseases: Conditions like diabetes and autoimmune disorders can impact eye health.
- Age: As we age, tear production often decreases, leading to dryness and itching.
- Digital Devices: Overuse of smartphones and computers can cause digital eye strain.
- Excessive Rubbing: Rubbing the eyes vigorously can worsen irritation.
- Inadequate Eyelid Hygiene: Poor cleaning of eyelids can lead to inflammation.
- Foreign Bodies: Small particles like dust or sand can get trapped in the eye.
- Eye Trauma: Injuries to the eye can result in itching and discomfort.
- Genetics: Some individuals may be more prone to eye irritation due to their genetic makeup.
