Stye eye infection: what to know

A stye, also known as a hordeolum, can cause a red, sore bump along the lid margin. The area may feel warm or gritty and can produce a small amount of discharge. Irritation may make the eye water, but a stye is centred in the eyelid rather than spread throughout the eyeball.

Several eyelid problems can look alike. A deeper, firm lump may behave differently from a tender bump, while widespread eye redness or heavy discharge may point to another condition. Avoid diagnosing the cause from discharge alone; the pattern and examination are relevant.

Apply a clean warm compress to the closed lid for several minutes, repeating this during the day. Keep the cloth clean and comfortably warm. Wash hands before touching the face, and use clean water to loosen crusting without rubbing the eye.

Do not squeeze or lance the swelling. Stop contact lenses and eye makeup until discomfort and discharge have cleared. Do not use someone else’s drops, ointment, towels, or cosmetics. If symptoms are worsening rather than easing, arrange a clinical review.

Seek urgent medical help if vision becomes blurred or reduced, light causes marked pain, the eye hurts when moving, or swelling spreads around the eye. Fever, severe pain, or feeling faint or very unwell also needs prompt attention.

A GP consultation is appropriate if the eyelid remains swollen, the lump repeatedly returns, discharge continues, or you cannot tell whether the eye surface is involved. A clinician can assess the lid and discuss whether prescription treatment is indicated.

Ask what features support a stye, whether the eye surface needs checking, and which treatment is suitable for your symptoms. Clarify when to resume lenses or makeup, how to clean the eyelid, and which changes should prompt same-day advice.
