Lid cysts are small, painless lumps that form on the eyelid. They are usually caused by a blockage in one of the oil glands that line the edge of the eyelid. These glands produce oil that helps to lubricate the eye and keep it moist. When a gland becomes blocked, the oil can build up and form a cyst.

There are two main types of lid cysts:

• Chalazia: These are the most common type of lid cyst. They are typically painless and slow-growing.
• Hordeola: These are also known as styes. They are usually smaller and more painful than chalazia, and they often develop more quickly.

What are the symptoms of lid cysts?

The most common symptom of a lid cyst is a lump on the eyelid. The lump may be:

• Painless or slightly tender
• Red or white
• Firm or movable

Other symptoms may include:

• Blurred vision if the cyst is large enough to press on the eye
• Irritated or watery eyes
• Sensitivity to light

How are lid cysts treated?

Most lid cysts do not require treatment and will go away on their own within a few weeks or months. However, if a cyst is large, painful, or causing vision problems, there are a number of treatment options available. These include:

• Warm compresses: Applying warm compresses to the affected eyelid for 10-15 minutes, several times a day, can help to melt the oil and unblock the gland.
• Eyelid massage: Gently massaging the eyelid can also help to unblock the gland.
• Steroid injections: If warm compresses and massage do not work, a doctor may inject a steroid medication into the cyst to help reduce inflammation.
• Drainage: In some cases, a doctor may need to drain the cyst using a needle.
• Surgery: If other treatments are not effective, surgery may be necessary to remove the cyst.

What are the risks of lid cysts?

Lid cysts are usually harmless and do not cause any serious complications. However, in rare cases, a cyst can become infected. If you think your cyst may be infected, see a doctor right away.

Here are some additional tips for preventing lid cysts:

• Keep your eyelids clean by washing them gently with warm water and soap every day.
• Remove your eye makeup every night.
• Avoid rubbing your eyes.
• If you have blepharitis, a condition that causes inflammation of the eyelids, treat it as directed by your doctor.
