Pinguecula: The Yellow Spot on the White of the Eye, Its Causes and Treatment
Medically reviewed by {{surgeon}}, {{surgeon's title and specialty}}, on {{review date}}. Last updated {{date}}.
Pinguecula (noun, plural pingueculae): a pinguecula is a small, yellowish, raised patch on the conjunctiva, the clear membrane over the white of the eye, most often on the side nearest the nose. It is a harmless, sun-related and age-related change in the tissue, not an infection and not a cancer. Most people have no symptoms, and the eye drops or surgery sometimes used are for irritation or appearance only.
Quick answer: a pinguecula is a benign yellow bump on the white of the eye, caused mainly by years of ultraviolet light, wind and dust. It usually needs no treatment; lubricating drops, sunglasses and, for a red inflamed spot, anti-inflammatory drops are the standard care. It does not normally disappear, but it can be removed for comfort or looks. Doç. Dr. (Associate Professor) Muhammet Derda Özer can examine it and advise.
Pinguecula: key facts
- What it is
- A raised, yellow-white degenerative lesion of the conjunctiva; the underlying collagen is replaced by thickened, abnormal tissue (elastotic degeneration)
- Where it is
- On the white of the eye next to the cornea, usually at the 3 and 9 o'clock positions, most often on the nasal side
- One eye or both
- Often both
- Main cause
- Long-term exposure to ultraviolet (UV) light, with wind and dust as additional irritants
- How common
- Very common with age. In the Blue Mountains Eye Study (Australia), 69.5% of people aged 49 and over had one
- Symptoms
- Usually none; sometimes dryness, grittiness, burning, itching, redness or a cosmetic concern
- Dangerous?
- No. It is benign and associated with minimal risk to the eye
- Treatment
- Often none; lubricants, UV protection and, when inflamed, anti-inflammatory drops. Surgery is an option, not a necessity

- Ophthalmologist; at Laser Istanbul Clinic, Doç. Dr. Muhammet Derda Özer (cornea and ocular surface)
What does a pinguecula look like?
A pinguecula looks like a small, slightly raised, yellow-white or cream-coloured spot on the white of the eye, sitting right beside the edge of the cornea (the clear dome over the iris). It stays on the white of the eye and does not grow across the clear part.
According to the American Academy of Ophthalmology (AAO), a pinguecula may contain protein, fat or calcium deposits. The College of Optometrists describes it as appearing on the conjunctiva at the 3 and 9 o'clock positions, and it often affects both eyes. It is usually on the nasal side: EyeWiki explains that light passing sideways through the cornea becomes focused on the nasal edge of the cornea, which concentrates UV exposure there.
Pinguecula symptoms
Most pingueculae cause no symptoms and are found by chance during an eye test. When pinguecula symptoms do appear, they include:
- a visible yellow or cream spot or bump, which some people find unattractive
- dryness, a gritty or "sand in the eye" feeling, burning or itching
- watering
- redness and swelling around the bump, called pingueculitis, when the lesion becomes inflamed
- discomfort with contact lenses (contact lens wearers are over-represented among people with pingueculae, according to the College of Optometrists)
A pinguecula does not normally affect your sight. Blurred vision is not a typical feature and is a reason to be examined (see below).
Pinguecula causes and risk factors
The main pinguecula cause is long-term exposure to ultraviolet light, together with wind and dust. The AAO names sunlight, wind and dust as the combined cause. Over the years these irritants damage the collagen in the conjunctiva, which is replaced by thickened yellowish tissue. Under the microscope this shows as elastotic degeneration, a sun-damage pattern.
Factors linked to a higher chance of having one, according to EyeWiki, the College of Optometrists and population studies:
- Age. The longer the exposure, the more likely the lesion; the College of Optometrists notes that most people have one by 70.
- Outdoor life and work. In a rural Shanghai study of 959 adults aged 50 or over, age and working outdoors (at least two hours of daily sunlight) were independent risk factors. In a Jordanian study, outdoor work was the only factor significantly linked to pinguecula.
- Living close to the equator, listed by EyeWiki.
- Male sex. In the Spanish study, 56.4% of men and 42.7% of women had a pinguecula.
- Contact lens wear and occupations with artificial UV exposure, according to the College of Optometrists.
- Smoking and diabetes appear in EyeWiki's risk list, but research is mixed. A 2023 study of 241 people found the same rate with and without diabetes (66.4% versus 66.5%), and a South Indian study found no link with smoking, alcohol or diabetes. Treat these as unproven.
How common is a pinguecula?
Pingueculae are common, though published rates vary widely with the age group studied, the climate and how people were examined:
| Study | Who was examined | Pinguecula found in |
|---|---|---|
| Blue Mountains Eye Study, Australia (1998) | 3,564 people aged 49+ | 69.5% |
| Shanghai, rural China (2015) | 959 people aged 50+ | 75.6% (age-adjusted) |
| Spain, general population (2011) | 619 adults | 47.9% |
| Tehran Eye Study, Iran (2009) | 4,564 residents | 22.5% (age- and sex-standardised) |
| South India (2012) | 7,774 people aged over 40 | 11.3% |
How is a pinguecula diagnosed?
An eye doctor diagnoses a pinguecula by looking at it. A slit-lamp examination, a microscope with a bright thin beam of light, shows a raised yellow-white lesion on the conjunctiva beside the cornea. Anterior segment OCT, a quick scan that images the front of the eye in cross-section, can be used to monitor its thickness.
The doctor also checks that it is not something else. The conditions to rule out, according to EyeWiki, include:
- Pterygium, a fleshy growth that can extend onto the cornea
- Conjunctival intraepithelial neoplasia (CIN) and other conjunctival growths such as papilloma, nevus (a pigmented mole) or, rarely, melanoma
- Limbal dermoid, a benign lump present from birth
- Conjunctivitis, an inflammatory cause of a red eye (see our guide to Eye infections: conjunctivitis, keratitis & endophthalmitis)
A yellow bump that has been the same for years is typically a pinguecula. A lesion that is growing, changing colour, pigmented or bleeding needs a specialist's examination.
Pinguecula vs pterygium
| Pinguecula | Pterygium | |
|---|---|---|
| Appearance | Yellow-white raised patch | Fleshy tissue with blood vessels |
| Location | On the white of the eye, beside the cornea | Starts on the white of the eye and can expand over the cornea |
| Effect on vision | Does not normally affect it | Can affect it if it grows over the cornea |
| Treatment | Usually none, or drops | Drops for comfort; surgical removal if it becomes a problem |
The two conditions share the same causes: UV light, wind and dust. Most pingueculae never turn into a pterygium. A 2026 genetic study of more than 3,000 people with either condition states that most pingueculae do not progress and that the two have partly different genetic susceptibility. EyeWiki notes that an inflamed pinguecula with a damaged corneal surface, or poor ocular surface lubrication, may progress to pterygium.
Surgical indications for pterygium listed in a 2021 review include a growth that threatens the line of sight, restricted eye movement, atypical features, or vision-reducing astigmatism. These are not reasons for surgery on a plain pinguecula.
Pinguecula treatment: what works?
Most pingueculae need no treatment. Where treatment is needed, it is for symptoms or looks, and it follows a stepped approach.
1. Protect the eye
UV protection is the one measure aimed at the cause. The AAO advises sunglasses with UV protection, protective glasses or goggles against dust, and artificial tears for dry eyes. EyeWiki says avoiding UV exposure may lower the incidence. Sunglasses will not shrink a pinguecula that is already there.
2. Pinguecula treatment at home
There is no home remedy that removes a pinguecula. What helps with symptoms:
- Artificial tears, used as often as needed, for dryness and grittiness
- A lubricating ointment, as the College of Optometrists suggests for irritation
- Sunglasses and a brimmed hat outdoors, and goggles in dusty or windy work
- Not rubbing the eye, which can add to the irritation
- Reviewing contact lens wear with your optometrist if lenses feel uncomfortable
An eye doctor should look at any bump that keeps becoming red or sore.
3. Pinguecula eye drops: which are best?
There is no single best eye drop for pinguecula, because the right drop depends on what the problem is.
| Problem | Typical drop | What the evidence says |
|---|---|---|
| Dryness, grit, burning | Artificial tears and lubricating ointment | First-line care in EyeWiki and the College of Optometrists |
| Red, swollen, sore (pingueculitis) | Anti-inflammatory drops, prescribed by a doctor | EyeWiki: topical steroids are used judiciously; topical indomethacin (a non-steroidal drop) also reduces inflammation. In a double-masked trial of 50 patients (33 with pinguecula), indomethacin 0.1% worked as well as dexamethasone 0.1% over 14 days, with fewer adverse effects after stopping. A separate placebo-controlled trial also found it effective |
| Yellow colour or bump size | None | No source we reviewed describes an eye drop that dissolves a pinguecula |
Steroid drops should only be used under medical supervision. Which anti-inflammatory drops are available varies by country, so a doctor decides.
4. Pinguecula removal
Surgery is usually not recommended or needed, according to the AAO. It may be considered when a pinguecula:
- is repeatedly inflamed and drops do not control it
- causes persistent dryness or a gritty feeling, or makes contact lenses hard to wear
- is cosmetically bothersome
- is suspected of being something else and needs to be removed for laboratory testing
The approaches described in EyeWiki are excision of the lesion with a conjunctival autograft held with fibrin glue (a thin piece of the patient's own healthy conjunctiva covers the area) and laser photocoagulation. The College of Optometrists also describes removal by surgery or laser. Evidence is limited to small studies. In a retrospective study of 31 patients, cosmetic results were rated excellent or good in 93.5% after excision with autograft and fibrin glue, with regression of blood vessels over 12 months. In a study of 30 patients, dry-eye measures and symptoms improved at 3 months after the same operation. Neither study is a guarantee for any individual eye. As with any eye surgery, ask your surgeon about the risks, including infection, scarring and regrowth.
Treatment with us: we examine pingueculae and other conjunctival and corneal surface conditions at Laser Istanbul Clinic and advise on whether removal is worthwhile. Doç. Dr. Muhammet Derda Özer leads our cornea and ocular surface care ({{confirm which surgeon performs pinguecula removal}}). If you are travelling to Istanbul for other treatment, the assessment can be done during the same visit.
Pinguecula removal cost
The cost depends on the technique, whether one or both eyes are treated, and the country. For pinguecula removal in Istanbul our price is {{price}} per eye. This includes the pre-operative examination and scans, surgery by your named surgeon, medication, follow-up checks in Istanbul, a personal interpreter, a coordinator and remote follow-up after you go home. Hotel and airport transfers are not included; we can arrange them for a separate charge on request. Flights are not included.
Does a pinguecula go away by itself?
A pinguecula does not normally go away by itself. It is a change in the structure of the conjunctival tissue, not something the eye clears. None of the clinical guidance we reviewed describes a pinguecula shrinking back on its own, and EyeWiki says it may grow slowly over time.
What does settle is the inflammation. A red, sore pingueculitis can calm with lubricants or anti-inflammatory drops, and the eye looks white again, but the small yellow bump remains. If you are searching "does pinguecula go away" because yours has suddenly changed or is growing, see an eye doctor rather than waiting.
Pinguecula on the NHS and in the UK
For pinguecula treatment in the UK, the College of Optometrists' clinical guidance, used by UK optometrists, recommends lubricants and UV protection, with anti-inflammatory drops if the lesion is inflamed. It notes that removal is rarely carried out on the NHS because it is classed as cosmetic.
Private removal in the UK, or treatment abroad, is therefore an option for people with persistent symptoms or who want the bump removed for cosmetic reasons. A lesion that might be something other than a pinguecula should be examined by an eye specialist, and that is a medical reason, not a cosmetic one. Ask your optometrist or doctor to confirm the cause of your red or yellow spot first, then decide on treatment.
Can a pinguecula be cancerous?
A pinguecula itself is benign. EyeWiki describes it as a non-malignant lesion with minimal ocular morbidity. The reason it is examined is that other conjunctival growths can look similar, including conjunctival intraepithelial neoplasia, papilloma, nevus and melanoma. Features that should prompt a specialist examination include rapid growth, a change in colour, pigmentation, bleeding, or a lesion that spreads onto the cornea. A surgeon can remove a lesion and send it for laboratory testing if there is any doubt.
When to see a doctor about a pinguecula
Book a routine eye examination if:
- you notice a new yellow spot on the white of the eye and have not had it checked
- it is dry, gritty, itchy or burning and lubricating drops do not settle it
- it is red and sore on and off
- you wear contact lenses and find them increasingly uncomfortable
- you want to talk about removal for comfort or appearance
Get same-day care from an eye doctor or eye emergency service if:
- the eye is painful, very red and sensitive to light, especially if you wear contact lenses (take them out and do not put them back in)
- there is discharge, or your vision is blurred or dropping
- the spot has grown quickly, changed colour, bleeds, or is spreading onto the clear part of the eye
- the problem followed a chemical splash or a sharp or high-speed injury
A pinguecula alone is not typically painful and does not cause discharge or loss of vision. If you have those, something else may be going on. If you already have a diagnosis and want a second opinion on whether removal is worthwhile, you can send photos and any eye reports for review before you travel.
Frequently asked questions
A pinguecula is a small, yellowish, raised patch on the conjunctiva, usually beside the cornea on the side nearest the nose. It is a benign, sun-related degeneration of the surface tissue and rarely causes problems.
Long-term ultraviolet light, wind and dust. The risk rises with age and outdoor exposure. In studies of adults aged 49 or over in Australia and China, around 70% had one.
Many people have none. Others notice dryness, grittiness, burning, itching, or redness when the bump becomes inflamed. It does not normally affect vision.
It depends on the problem. Artificial tears help dryness and grittiness. For a red, inflamed pinguecula, a doctor may prescribe anti-inflammatory drops, such as a steroid or the NSAID indomethacin 0.1%, which performed as well as a steroid in one trial. No source we reviewed describes a drop that makes the yellow bump disappear.
No. The bump is a structural change in the tissue; it normally stays and may grow slowly. The redness and irritation can settle with treatment.
You can ease symptoms with artificial tears, UV-blocking sunglasses, a hat, goggles in dust or wind, and by not rubbing the eye. Nothing at home removes the bump itself.
Yes. A surgeon can excise it, often covering the area with a thin graft of your own conjunctiva held in place with fibrin glue. It is usually done for persistent symptoms or appearance rather than medical necessity. Discuss risks such as infection, scarring and regrowth first.
Rarely. The College of Optometrists says removal is seldom performed on the NHS because it is classed as cosmetic. Inflamed lesions are treated with drops, and a specialist should examine anything that might be another condition.
It varies by country, technique and number of eyes treated. In Istanbul our price is {{price}} per eye, including examination, surgery, medication, follow-up checks, a personal interpreter and a coordinator. Hotel and airport transfers are charged separately.
Sometimes, but most do not. EyeWiki notes that an inflamed pinguecula with a damaged corneal surface or poor lubrication may progress. A pterygium is a fleshy, vascular growth that can expand over the cornea.
