Pinguecula

Pinguecula Treatment in the Bay Area – Yellow Spot on the Eye

If you have noticed a small yellow spot or raised bump on the white part of your eye, it may be a pinguecula. This common eye condition is usually harmless, but the area can sometimes become red, dry, irritated, or increasingly noticeable.

At Peninsula Laser Eye Medical Group, we evaluate yellow spots, bumps, and other changes on the surface of the eye. A comprehensive eye examination can confirm whether the growth is a pinguecula and help rule out other conditions that may look similar.

What Is a Pinguecula?

A pinguecula is a small, non-cancerous growth that develops on the conjunctiva—the clear membrane covering the white part of the eye, known as the sclera.

The growth may contain deposits of protein, fat, or calcium, which can give it a white, cream-colored, or yellow appearance. Although a pinguecula can form on either side of the eye, it is most often found on the nasal side, between the cornea and the inner corner of the eye.

A pinguecula remains on the conjunctiva and does not grow across the cornea. If tissue begins extending onto the cornea, it may instead be a pterygium, another type of benign growth that requires evaluation.

What Does a Pinguecula Look Like?

People often search for a pinguecula because they have noticed a:

• Yellow spot on the white of the eye
• Small yellow bump near the iris
• Raised white or cream-colored area on the eyeball
• Bump on the inner corner of the eye
• Yellow patch that becomes red or irritated
• Small growth beside the cornea

A pinguecula may occur in one or both eyes. It usually develops gradually and may become more noticeable over time.

Because several eye conditions can cause a bump, spot, or color change, an eye examination is the best way to determine exactly what you are seeing.

What Causes a Pinguecula?

Pingueculae are associated with long-term exposure to ultraviolet radiation and chronic irritation of the eye’s surface. Factors that may contribute include:

• Frequent or prolonged sun exposure
• Wind, dust, smoke, and dry air
• Living or working in a sunny climate
• Spending significant time outdoors
• Chronic dry eye
• Exposure to welding or other sources of UV radiation
• Repeated environmental irritation

The Bay Area’s sunny weather, coastal wind, and outdoor lifestyle may increase exposure to some of these contributing factors.

Pingueculae become more common with age, but younger adults who spend substantial time outdoors can also develop them.

What Are the Symptoms of a Pinguecula?

Many pingueculae cause no symptoms. A person may only notice the yellow spot while looking in the mirror or after someone else points it out.

When irritation or inflammation occurs, symptoms may include:

• Eye redness
• Dryness or burning
• Itching
• Tearing
• A gritty or sandy sensation
• Feeling as if something is stuck in the eye
• Discomfort while wearing contact lenses
• A visibly swollen or irritated bump

An inflamed pinguecula is sometimes called pingueculitis. Symptoms may become more noticeable after sun, wind, dust, smoke, or prolonged exposure to dry environments.

Is a Pinguecula Dangerous?

A pinguecula is typically benign, meaning it is non-cancerous. It usually does not threaten vision and does not require treatment if it is small and comfortable.

However, not every yellow, white, or raised area on the eye is a pinguecula. Certain uncommon growths and other eye-surface conditions can appear similar. A new or changing spot should therefore be examined rather than self-diagnosed.

Schedule an eye examination if the area:

• Changes in size, shape, thickness, or color
• Becomes increasingly red or painful
• Causes persistent irritation
• Interferes with blinking or contact lens wear
• Is associated with blurred vision
• Begins extending onto the cornea
• Looks different from a previously diagnosed pinguecula

Seek prompt medical attention for sudden vision loss, significant eye pain, marked light sensitivity, an eye injury, or rapidly worsening redness.

How Is a Pinguecula Diagnosed?

A pinguecula can usually be diagnosed during a routine eye examination. Your eye doctor may examine the front of the eye with a slit lamp, a specialized microscope that provides a magnified view of the conjunctiva, cornea, and surrounding structures.

Additional testing is not usually necessary. If the appearance is unusual or the diagnosis is uncertain, your doctor may recommend closer monitoring or additional evaluation.

Does a Pinguecula Go Away?

A pinguecula generally does not disappear on its own. Lubricating drops and other treatments can relieve dryness, redness, and inflammation, but they do not typically remove the growth itself.

Many pingueculae remain small and stable for years. If the spot is not uncomfortable or changing, monitoring and preventive care may be all that is needed.

How Is a Pinguecula Treated?

Treatment depends on whether the pinguecula is causing symptoms.

Artificial Tears

Lubricating eye drops can help reduce dryness, burning, and the sensation that something is in the eye. Preservative-free artificial tears may be preferable for people who need drops frequently.

Prescription Eye Drops

If the pinguecula becomes inflamed, an eye doctor may prescribe a short course of anti-inflammatory medication, such as a mild steroid eye drop.

Steroid drops should only be used under an eye doctor’s supervision. Improper or prolonged use can cause complications, including increased eye pressure.

Dry Eye Treatment

Dry eye can make a pinguecula feel more irritated. Depending on your symptoms, treatment may include lubricating drops, nighttime ointments, environmental changes, prescription dry-eye medication, or punctal plugs to help retain tears.

Contact Lens Adjustments

A raised pinguecula can occasionally interfere with contact lens comfort. Your eye doctor can evaluate the fit of your lenses and recommend changes if necessary.

Can a Pinguecula Be Removed?

Pinguecula removal is not necessary for most patients. Surgery may be considered when the growth:

• Causes persistent discomfort despite other treatment
• Repeatedly becomes inflamed
• Interferes with blinking or contact lens wear
• Has an unusual appearance requiring further evaluation
• Is a significant cosmetic concern

During pinguecula surgery, the abnormal tissue is carefully removed from the surface of the eye. Your eye doctor will discuss the expected healing process, possible risks, and the chance that the growth could return.

If you are considering removal because of the appearance of a yellow spot on your eye, a consultation can help determine whether surgery is appropriate and what results you can reasonably expect.

Pinguecula vs. Pterygium: What Is the Difference?

Pinguecula and pterygium are both benign growths associated with UV exposure, dryness, and environmental irritation, but they are not the same condition.

A pinguecula is usually a small yellow or white bump that remains on the conjunctiva beside the cornea. A pterygium is typically a wedge-shaped growth that extends from the conjunctiva onto the cornea.

Because a pterygium can alter the shape of the cornea and potentially affect vision, distinguishing between these two conditions is important. An eye doctor can usually tell the difference during a slit-lamp examination.

How Can I Prevent a Pinguecula From Getting Worse?

You may not be able to make an existing pinguecula disappear without removal, but you can reduce the irritation and UV exposure that may contribute to progression.

Helpful steps include:

• Wear sunglasses that block 99% to 100% of UVA and UVB radiation
• Choose wraparound sunglasses for added protection from wind and dust
• Wear a brimmed hat when spending time outdoors
• Use artificial tears when your eyes feel dry
• Avoid smoke, dust, and direct airflow when possible
• Wear proper protective eyewear while welding or working around debris
• Avoid rubbing irritated eyes
• Follow your eye doctor’s recommendations for managing dry eye

UV protection is helpful even on cloudy days, since ultraviolet radiation can still reach the eyes.

Frequently Asked Questions About Pinguecula

Why do I have a yellow spot on my eye?

A yellow spot on the white of the eye is often a pinguecula, particularly when it is located beside the cornea. However, other eye-surface conditions can have a similar appearance. An eye examination is needed for an accurate diagnosis.

Can a pinguecula affect vision?

Most pingueculae do not directly affect vision because they remain beside the cornea. A larger or raised growth may contribute to tear-film problems and irritation. If tissue is growing onto the cornea or your vision is changing, your eye doctor will also evaluate you for a pterygium or another condition.

Can eye drops remove a pinguecula?

Eye drops can relieve dryness, redness, and inflammation, but they generally cannot eliminate the growth. Surgical removal is the only way to physically remove a pinguecula.

Is a pinguecula contagious?

No. A pinguecula is not an infection and cannot spread from one person to another.

Is a pinguecula cancerous?

A typical pinguecula is benign and non-cancerous. Nevertheless, any growth that changes in appearance should be examined because other, less common conditions may resemble it.

Can I wear contact lenses with a pinguecula?

Many people can continue wearing contact lenses. If the bump causes rubbing, redness, dryness, or poor lens fit, an eye doctor may recommend a different lens, a temporary break from contact lens use, or treatment for accompanying dry eye.

Should I try to remove a pinguecula myself?

No. Do not scrape, puncture, or apply unapproved products to a growth on the eye. Doing so could cause infection, scarring, or permanent damage.
