Pinguecula: Causes, Symptoms, and Treatment

What kind of doctor treats Pinguecula?

An ophthalmologist (an eye doctor who can also do eye surgery) or an optometrist (an eye care professional who checks vision and eye health) usually diagnoses and treats a pinguecula. A primary care doctor can also take a first look. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is pinguecula?

A pinguecula is a common growth on the conjunctiva that is not cancer. The conjunctiva is the clear, thin tissue that covers the white part of the eye. The growth forms in the part of the conjunctiva that is exposed when the eye is open. The plural is pingueculae. It is a raised, yellow-white spot. The condition is benign, which means it is not cancer, and the outlook is good.

Symptoms

A pinguecula looks like a small, yellowish bump on the conjunctiva near the cornea, the clear front window of the eye. It can appear on either side of the cornea, but it more often grows on the side closest to the nose.

Most people have no symptoms. Some people feel irritation, such as a feeling that something is in the eye, tearing, burning, or itching. Some people also dislike how the bump looks. A pinguecula that becomes inflamed, or swollen and sore, is called pingueculitis. The growth may get bigger, but this usually happens over many years.

Causes and who gets it

The exact cause is unknown. Long-term sunlight exposure and eye irritation may be factors. Wind and dust are also thought to play a part, along with aging. Doctors say the link to sunlight is not yet well proven. Arc-welding is a major risk linked to work.

Other risk factors include living near the equator, spending a lot of time outdoors, older age, male sex, smoking, and diabetes. A pterygium is a related growth that spreads over the cornea and can block vision. The two conditions occur under similar conditions, but they are thought to be separate diseases.

How doctors diagnose it

An eye exam is often enough to diagnose a pinguecula. Doctors usually look at the eye with a slit lamp, a microscope with a bright light made for the eye. The classic growth is raised and yellow-white, and it is more common on the nose side than the outer side. A biopsy, which is a small tissue sample, is not usually needed. It may be done if the growth looks unusual and the diagnosis is still unclear.

Treatment

Most people need only lubricating eye drops, also called artificial tears. Keeping the eye moist may help stop the area from becoming inflamed. If the area becomes inflamed, a doctor may prescribe mild steroid eye drops for a short time. Doctors discourage long-term steroid drops because of side effects. An anti-inflammatory drop called indomethacin has also been shown to ease symptoms of inflammation.

Rarely, the growth needs to be removed for comfort or for cosmetic reasons. Doctors suggest removal only when the growth looks unacceptable to the patient, stays inflamed, or gets in the way of contact lens wear. Both laser treatment and surgery to cut out the growth have worked well, with similar cosmetic results.

Things that may help prevent a pinguecula or keep it from getting worse include keeping the eye well lubricated with artificial tears, wearing good quality sunglasses, and avoiding eye irritants.

When to see a doctor

Contact your health care provider if the growth changes in size, shape, or color. Also contact your provider if you would like to have it removed. A growth that spreads over the cornea can block vision, so tell your eye doctor if your vision changes.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can look at the eye, talk through your symptoms, and refer you to an eye doctor for an exam or for removal.

Common questions

Is a pinguecula cancer?

No, a pinguecula is not cancer. It is a benign growth, and the outlook is good. Contact your provider if it changes in size, shape, or color.

Can a pinguecula turn into a pterygium?

Possibly, but doctors think they are separate diseases that occur under similar conditions. A pterygium is a growth that spreads over the cornea and can block vision.

Does a pinguecula need to be removed?

No, most people do not need surgery. Removal is rarely needed, and it is done for comfort or for cosmetic reasons.

Can sunglasses help prevent a pinguecula?

They may help. Good quality sunglasses are on the list of steps that may help prevent a pinguecula or keep it from getting worse. Avoiding sun exposure may also lower the chance of getting one.
