Causes, Symptoms, Treatment, and More
A pinguecula (plural: pingueculae) is a common, often harmless eye condition where a yellowish, slightly raised lesion forms on the surface of the eye. While often harmless, pingueculae can cause discomfort and, in some cases, require medical intervention.
Discover more about the causes of pinguecula, its symptoms, and pinguecula treatment options, including pinguecula surgery when necessary.
What is Pinguecula?
Pinguecula is a benign growth on the sclera, which is the white of your eye, usually near the side which is closest to your nose. The lesion is composed of a mixture of proteins, lipids, and calcium, leading to a yellowish appearance. Pingueculae can occur in one of both eyes and are generally small in size but can become inflamed or irritated over time, causing redness and sometimes affecting your vision.
What Causes Pinguecula?
Several factors contribute to pinguecula development:
- UV Exposure: Long-term exposure over the course of years to ultraviolet (UV) light from the sun is the primary risk factor for pinguecula.
- Environmental Factors: Wind, dust, and dry conditions can irritate the eyes and contribute to the development of pingueculae.
- Contact lenses: Sometimes contact lens wear can exacerbate the condition when exposed to environmental elements.
Symptoms of Pinguecula
Most individuals with pingueculae experience few symptoms as you can’t usually feel them in your eyes. However, when pingueculae become irritated or inflamed, this can lead to pingueculitis.
Common pinguecula symptoms include:
- Foreign Body Sensation: Often described as feeling like you have a piece of sand in your eye.
- Eye Redness: From irritation and inflammation around the lesion.
- Swelling: Inflammation may cause swelling.
- Dryness: When pinguecula obstructs tears from spreading across the eyes to keep them moist.
- Blurred Vision: Pingueculae can cause mild visual disturbances, if it grows and starts to cover more of your eye.
We can diagnose pinguecula during a routine eye exam.
Pinguecula Treatment and Relief
Most cases of pinguecula do not require treatment unless symptoms like irritation, inflammation, or discomfort persistently occur. In this instance, the treatment options available to manage the symptoms include:
1. Lubricating Eye Drops
For mild irritation and dryness, artificial tears are often sufficient to relieve pinguecula symptoms.
2. Anti-inflammatory Medications
If pingueculitis occurs, steroid eye drops, or non-steroidal anti-inflammatory drugs (NSAIDs) may be recommended to reduce swelling and inflammation.
3. Sun Protection
Wearing sunglasses with 100% UV protection is essential for preventing further damage from UV, wind and dust exposure, which are the leading causes of pingueculae.
4. Surgery for Severe Cases
In rare cases, when pingueculae surgical removal may be necessary when regular treatments don’t provide relief or if the condition significantly affects your quality of life.
Pinguecula Surgery: When is it Necessary?
Pinguecula surgery is typically considered when:
- Vision is affected: If the pinguecula interferes with normal vision or contact lens wear.
- Severe inflammation: If inflammation and swelling are persistent or recurrent as a result of the pingueculae and do not respond to medication.
- Contact lens discomfort: If your ability to wear contact lenses comfortably is affected by the pinguecula.
During pinguecula surgery, the lesion is carefully removed from the surface of the eye. This outpatient procedure is typically quick, minimally invasive and performed under local anesthetic. Recovery time is usually short, and patients are often able to resume normal activities within a few days, providing you follow post-operative care guidelines provided by your eye surgeon.
Pinguecula and Pterygium: The Connection
Pterygium is another eye condition that can result from prolonged exposure to UV light and environmental irritants, much like pinguecula. While pingueculae are typically small and benign, pterygia are larger, wing-shaped growths that can grow over the cornea and interfere with vision. Pingueculae can sometimes develop into pterygium over time, particularly when the irritants that caused the initial growth continue to affect the eye.
FAQ: Pingueculae
Pinguecula is a yellowish, raised lesion that forms on the white part of the eye (sclera).
Symptoms often don’t occur if you have pingueculae, but when they do you may experience a foreign body sensation, eye redness, swelling, dryness, and mild visual disturbances.
The primary causes of pinguecula are prolonged UV exposure and environmental factors like wind and dust.
Treatment for pinguecula often includes lubricating eye drops, anti-inflammatory medications, and wearing sunglasses for UV protection. In rare cases, surgery may be an option.
Pinguecula surgery is typically reserved for severe cases where the lesion interferes with vision, contact lens wear, or causes persistent irritation. The surgery involves removing the pinguecula from the surface of the eye.
