A visible spot on the white of your eye, sometimes described as a “star,” is almost always a pinguecula or pterygium. These are small, raised growths on the clear tissue covering the white part of your eye. Both are extremely common, usually harmless, and treatable. Whether yours needs drops, surgery, or just UV protection depends on its size, location, and how much it bothers you.
Before diving in: if you’re seeing flashing stars or floating specks in your vision rather than a visible spot on the surface of your eye, that’s a completely different issue. Sudden flashes of light, new floaters, blurred vision, or a curtain-like shadow creeping across your field of view can signal retinal detachment, which is a medical emergency. Get to an eye doctor immediately if those symptoms appear.
What That Spot Actually Is
A pinguecula is a small, raised bump on the white of your eye. It’s typically white or yellowish and stays on the conjunctiva, the clear membrane that covers the sclera. It can show up on either side of the iris but doesn’t grow onto the colored part of your eye or the clear window in front of it.
A pterygium (sometimes called “surfer’s eye”) starts the same way but keeps growing. It’s a wedge-shaped tissue that extends from the white of the eye onto the cornea, the clear surface that covers your pupil. This is the one that can eventually interfere with vision if it grows large enough. Both conditions are driven primarily by UV exposure, wind, and dry or dusty environments.
The key distinction: a pinguecula stays put on the white part; a pterygium creeps toward the center of your eye. Your eye doctor can tell you which one you have in a single visit.
When Treatment Is Necessary
Most pingueculae never need treatment beyond basic comfort measures. They’re cosmetically annoying but not dangerous. A pterygium, however, may need intervention if it starts distorting your vision. A growth larger than 3 mm on the cornea can begin warping its shape, causing astigmatism. Once it passes 3.5 mm (roughly halfway to the center of your pupil), it often causes noticeable blurring.
Eye doctors generally recommend surgical removal for four reasons: the growth is warping your vision, it’s threatening to reach the visual axis (the center of your cornea), it causes persistent irritation that drops can’t manage, or you want it removed for cosmetic reasons. That last one is completely valid. Many people seek removal simply because they don’t like how it looks.
Managing Symptoms Without Surgery
If your growth is small and not affecting your vision, the first line of treatment is artificial tears. Lubricating eye drops reduce the “something stuck in my eye” feeling that pingueculae commonly cause and help with redness and dryness. You can find these over the counter at any pharmacy. Using them several times a day, especially in dry or windy conditions, is usually enough to keep a small growth comfortable.
When a pinguecula or pterygium becomes inflamed (red, swollen, and painful), your eye doctor may prescribe a short course of steroid eye drops. These are typically used two to four times daily and work quickly to calm irritation. Steroid drops are not a long-term solution. Extended use can raise the pressure inside your eye or contribute to cataract formation, so they’re reserved for flare-ups and used under close supervision. If symptoms don’t improve within two days on steroid drops, your doctor will want to reassess.
Surgical Removal
Surgery is the only way to fully remove a pterygium or pinguecula. The procedure has evolved dramatically over the past two decades. Simply cutting the growth off and leaving the area bare led to recurrence rates as high as 80%. Modern techniques use a patch of your own conjunctival tissue (taken from under your eyelid) to cover the spot where the growth was removed. This approach, called a conjunctival autograft, brought recurrence rates down to less than 5%.
An alternative uses amniotic membrane grafts instead of your own tissue, but recurrence rates are higher with this method, up to around 40% in some analyses compared to under 18% with autografts. Some surgeons have refined the technique even further. One approach, developed over more than 700 surgeries, uses tissue glue instead of stitches and addresses the deeper layers of the growth (not just the visible surface). This technique reports recurrence rates below 0.5% and aims for a cosmetically clear, white eye starting on the first day after surgery.
If cosmetic outcome matters to you, ask your surgeon specifically about their technique, whether they use sutures or glue, and what their personal recurrence rate is. These details vary significantly from surgeon to surgeon.
What Recovery Looks Like
Expect your eye to be quite sore for about a week after surgery. Redness typically takes two to three weeks to clear, and your vision may stay slightly blurry for up to six weeks before returning to its pre-surgery baseline.
During the first week, you’ll wear a protective shield at night, avoid rubbing your eye, and skip makeup. Plan on roughly two weeks off work, depending on your job. Strenuous exercise like jogging, cycling, or aerobics should wait at least two weeks. Swimming is off-limits for four weeks. You’ll have a follow-up appointment about one week after surgery so your doctor can check healing and graft attachment.
Skip the Home Remedies
Online forums recommend apple cider vinegar, castor oil, activated charcoal, and tea tree oil for eye growths. None of these have been tested in controlled clinical studies. Apple cider vinegar is acidic enough to damage the cornea, and tea tree oil applied near the eyes has caused notable irritation in reported cases. There is no proven natural remedy that shrinks or removes a pinguecula or pterygium. At best these do nothing; at worst they cause a chemical injury to a very delicate surface.
Preventing Growth and Recurrence
UV radiation is the primary driver of these growths, so consistent sun protection is the single most important thing you can do, whether you’re trying to stop a small spot from getting bigger or prevent a surgically removed one from coming back.
Look for sunglasses labeled “UV400” or “100% UV protection,” which block all UVA and UVB rays up to 400 nanometers. Wraparound or oversized frames that sit snugly against your face are ideal because they block light coming in from the sides and top. A wide-brimmed hat adds another layer of protection. If you work outdoors, are regularly around water or sand (which reflect UV light upward toward your eyes), or live in a sunny climate, wearing these consistently makes a measurable difference in whether a small growth stays small or progresses into something that needs surgery.
