Discover a small white button in the eye may be disturbing. Located on the eyelid, the conjunctiva or sometimes even on the cornea, this type of lesion has various origins. Some are benign and absorb themselves, while others require rapid consultation with an ophthalmologist. In this article, we explain in detail the main causes, symptoms to be monitored and solutions to effectively relieve or treat this eye problem.
The main causes of a small white button in the eye
One small white button in the eye does not always have the same meaning. Depending on its location and appearance, it may be a simple cyst, infection or inflammatory reaction. Proper identification of the cause is essential for choosing the appropriate treatment.
One of the most frequent causes isBarley, a small bacterial infection of the follicle of a cilia. It usually appears as a red and white button, sometimes painful to the touch. Not to be confused with the Chalazion, which looks like a little hard and painless ball in the eyelid.
Other origins exist, such as Pinguecula, a small whitish or yellowish outgrowth on the conjunctiva, or conjunctival cyst, often benign but visually embarrassing.
Summary table: possible causes of a small white button depending on its location
To better understand the origin of a small white button in the eyeIt is essential to consider its location. A comparison table summarizes the most common causes and associated symptoms:
| Location of the button | Possible causes | Characteristics | When to consult? |
|---|---|---|---|
| Eyelid (board or inside) | Orgelet, Chalazion | – Orgelet: painful, red, white dot filled with pus – Chalazion: painless, firm ball, persists several weeks | If severe pain, swelling or persistence beyond 2-3 weeks |
| Conjunctiva (white eye surface) | Conjunctival Kyste, Pinguecula, Calcic Concretions | – Kyste: small transparent/white vesicle – Pinguecula: yellowish or whitish UV-related deposit – Concretions: small whitish dots | If visual discomfort, inflammation or height increase |
| Cornea (transparent surface in front of the pupil) | Corneal Ulcer, Keratite | – Opaque white patch on cornea – Pain, redness, loss of vision frequent | Immediate ophthalmological emergency |
| Internal or external corner of eye | Kyste lacrymal, Local infection | – Small white ball near the tear canals – Sensitivity, sometimes flow | If redness, pain or lacrimation persists |
This table helps to guide the interpretation of the symptom. However, only one ophthalmologist is able to confirm the diagnosis and offer suitable treatment.
A mild but painful infection
LBarley is the most common cause when talking about a white button at the edge of the eyelid. It results from an infection with a bacterium (often a staphylococcus) of a hair follicle or a Meibomius gland.
Typical symptoms are a small, painful red ball that quickly evolves to a white point containing pus. The eye can become tearing and sensitive to light. Although impressive, barleylet usually heals spontaneously in a few days.
Treatment consists mainly of Hot compresses applied several times a day. In some cases, an antibiotic eye drops may be prescribed by a doctor if the infection persists or becomes complicated.
Chalazion: a little painless ball
In contrast to barley, the Chalazion is not infectious but inflammatory. It is caused by the obstruction of a Meibomius gland, which produces the lipid film of tears.
A chalazion presents itself as a small button or a firm ball in the eyelid, often painless. It may persist for several weeks or months if not treated.
In most cases, warm compresses are sufficient to unblock the gland. However, if the chalazion becomes too embarrassing, the ophthalmologist may propose a small incision to remove it.
Pinguecula: a small outgrowth due to external aggression
Another common cause of button white in eye is Pinguecula. It is a whitish or yellowish deposit located on the conjunctiva, often on the side of the nose.
Pinguecula is generally related to exposure to UV rayswind, dust or dry eyes. It is benign but can become irritated, causing a feeling of discomfort.
Treatment is not always necessary, but the sunglasses protection and use of artificial weapons can limit its evolution. In rare cases, surgery may be considered if pinguecula becomes too unsightly or uncomfortable.
Conjunctival cysts and other benign lesions
One conjunctival cyst is a small transparent or whitish vesicle, usually filled with liquid. It is benign and often discovered by chance, as it does not always cause symptoms.
Ces kystes peuvent apparaître après une irritation, un traumatisme ou une chirurgie oculaire. Dans la plupart des cas, ils disparaissent spontanément. Si ce n’est pas le cas, un ophtalmologue peut les enlever rapidement en consultation.
D’autres petites lésions bénignes, comme des dépôts de calcium (concrétions conjonctivales), peuvent également apparaître sous forme de petits points blancs dans l’œil.
Quand s’inquiéter d’un petit bouton blanc dans l’œil ?
La majorité des causes d’un small white button in the eye sont bénignes. Toutefois, certains signes doivent alerter et justifier une consultation rapide chez un ophtalmologue.
Il est recommandé de consulter en urgence si le bouton est associé à une douleur intense1 baisse de vision1 rougeur importante1 light sensitivity (photophobie) ou un écoulement anormal. Ces symptômes peuvent indiquer une infection ou une atteinte cornéenne qui nécessite un traitement rapide.
Un bouton qui persiste plusieurs semaines sans amélioration doit également être examiné, car certaines lésions plus rares (comme des tumeurs bénignes ou malignes) peuvent ressembler à un simple bouton au début.
Les traitements possibles selon la cause
Le traitement d’un button white in eye dépend de son origine. Les orgelets et chalazions se traitent généralement par des mesures simples comme les compresses chaudes. Les collyres ou pommades antibiotiques peuvent être prescrits en cas d’infection persistante.
Dans le cas d’une pinguecula ou d’un kyste conjonctival, un traitement n’est pas toujours nécessaire. Des larmes artificielles peuvent soulager l’inconfort. En cas de gêne esthétique ou fonctionnelle, l’ophtalmologue peut proposer une petite intervention.
Il est essentiel de ne pas essayer de percer ou de frotter le bouton soi-même, car cela risque d’aggraver l’inflammation ou de provoquer une surinfection.
