Styes and Chalazia (Eyelid Lumps)

What is a Styes and Chalazia?

A stye is a red, painful bump on the eyelid, similar to a small pimple. It happens when an oil gland in the eyelid becomes blocked and infected. Styes can cause tenderness, swelling, and irritation.

If the swelling lasts longer and becomes painless, it may turn into a chalazion. A chalazion is a firm lump inside the eyelid, caused by the body’s reaction to a blocked oil gland. Unlike styes, chalazia are usually not painful but may cause a visible bump.

Symptoms You May Notice

  • A red or tender lump on the eyelid
  • Swelling in one area of the lid
  • A scratchy or gritty feeling in the eye
  • Watery or irritated eyes
  • Crust or flakes around the eyelashes

Why Do They Happen?

Your eyelids have many small oil glands. When the oil becomes too thick or sticky, the glands can clog. This can lead to swelling and bumps. Factors that increase the risk include:

  • Eyelid inflammation (blepharitis) or rosacea
  • Touching or rubbing your eyes often
  • Not fully removing eye makeup
  • Having oily skin or dandruff

Treatment

Home Care (First Step)

  • Apply a warm, damp cloth to the eyelid for 10–15 minutes, several times a day.
  • Gently clean the eyelid with diluted baby shampoo or lid wipes.
  • Do not squeeze or pop the lump.
  • Use artificial tears if the eye feels dry.

Medical Treatment

If the lump is large, painful, or does not go away:

  • Antibiotic drops or ointment may be prescribed (if infection is present).
  • A steroid injection may help reduce swelling.
  • In some cases, a minor procedure can drain the lump.

Risks and Considerations

Most styes and chalazia go away on their own with simple care. Rarely, they may come back or leave a small scar. Procedures carry a small risk of infection, bleeding, or recurrence.

Summary

Styes and chalazia are common eyelid problems and are usually not serious. Warm compresses and gentle eyelid hygiene often help them heal. If a lump does not improve or keeps coming back, see your oculoplastic surgeon for further treatment.
