Chalazion

A chalazion is a cyst, or fluid-filled sac, of one of the little glands in edge of the eyelids Chalazions differ from hordeolums in that they are usually painless apart from the tenderness caused when they swell up. Typically, this lump grows over days to weeks and is occasionally red, warm, or painful Reported origins include a Greek word meaning small lump, a Greek word meaning hailstone, and a Greek word meaning pimple. This gland produces oil. When this gland becomes blocked, it can rupture and the inflammation process begins. When a chalazion is small and without symptoms, it may disappear without treatment. If they become large enough to press on the cornea, they may cause a temporary astigmatism , resulting in a decrease in vision. Occasionally, the chalazion enlarges and breaks through the tarsal plate to the external portion of the eyelid. A sty can resemble a chalazion in the sense that it is also a lump in the eyelid. However, a sty involves glands and eyelash hair follicles that are closer to the skin surface of the eyelid. Some people are prone to developing styes and chalazia. However, when the chalazion doesn't respond to this kind of conservative treatment, or when it is too large, or when it comes back many times despite initial successful conservative treatment, surgery is the only appropriate treatment.

A chalazion is a localized, hard lump located on the eyelid, usually near the eyelashes. A hordeolum is an acute infection of the Zeis glands, while a chalazion is usually sterile. The large meibomian glands are embedded in the tarsal plate of the eyelid; therefore, edema usually is contained on the conjunctival portion of the lid. It rarely produces eye pain or changes in your sight. With care, it should be gone in 1 to 2 months. The gland involved in the formation of a chalazion is a modified sweat gland that lies within the eyelid. A chalazion is usually a reaction to trapped oil secretions and not caused by bacteria, although the site can become secondarily infected by bacteria. A chalazion may eventually disappear on its own after a few months, though more often than not, some treatment is necessary.

Causes of Chalazion

The common Causes of Chalazion :

• High blood lipid concentrations (possible risk from increased blockage of sebaceous glands)
• Chronic blepharitis
• Immunodeficiency
• The eyelid has approximately 100 of these glands, located near the eyelashes
• Swelling may also occur in other parts of the eye due to a secondary infection.
• This causes a chalazion to form near the edge of the eyelid.
• A chalazion begins as diffuse swelling and tenderness, and later forms a cyst-like localized swelling.
• A chalazion develops when blockage in an oil gland causes it to swell.
• A chalazion is caused by inflammation of the meibomian glands (termed meibomianitis or, alternatively, meibomitis ).

Symptoms of Chalazion

Some common Symptoms of Chalazion :

• Raised, swollen bump on the upper or lower eye lid
• May be tender and sore
• A chalazion appears as a localized hard lump that may grow as large as an eighth of an inch.
• Occasionally, you may feel pain and your eyelid may be red.
• Painful swelling on the eyelid
• Sensitivity to light
• Eyelid tenderness
• Increased tearing
• Blurred vision
• discomfort in the eye or difficulty with seeing if the chalazion is large (swelling of the eyelid is usually not painful)

Treatment of Chalazion

• The eye can be patched, and the patient should be kept comfortable during transportation.
• Defer steroid injections and surgical drainage to an ophthalmologist or plastic surgeon.
• Expectations for the course of the condition
• If no evidence of infection is present, inject the chalazion with a steroid (eg, triamcinolone, methylprednisolone).
• Lightly massage the area several times a day.
• Antibiotic eye drops are usually used several days before and after removal of the cyst , but are otherwise of little value in treating a chalazion.
• Do not "pop" or scratch the chalazion.
• your child's tolerance for specific medications, procedures, or therapies
• Antibiotic drops for the eye
• Hot compresses (gently done - the eye can be very sensitive) may help to soothe the discomfort and open the duct, allowing the chalazion to drain freely
