A chalazion is a small bump in the eyelid caused by a blockage in the oil glands known as meibomian glands in the eyelid. A chalazion is characteristically painless, slowly increasing nodule on the eyelid. The meibomian glands are the glands that produce the fluid that lubricates the eye.
Eyelids are the movable tissues of eyes. They are made up of skin and muscles. Eyes are protected by eyelids from mechanical injury and helps in providing the moist chamber that is required for normal functioning of cornea and conjunctiva.
Eyelids are made up of:
• A fibrous plate called tarsus gives the structure and shape to eyelids
• Muscles which helps in moving the eyelids.
• Meibomian glands.
Lining of mucous membrane covers the inside of eyelids and eyelashes are present at the border of eyelids. Orbiuclaris oculi helps in movement of eyelids.
Impulse of closing the eyelids comes by facial (seventh cranial) nerve, and impulse of opening comes by oculomotor (third cranial) nerve. Borders of eyelids are lubricated by an oily secretion by meibomian glands. This secretion helps in forming part of the tear film and in reducing in evaporation of tear.
On everting the lid margin, meibomian gland is seen. On applying pressure on the lid thick secretion comes out.
Product of lipid breakdown (either from bacterial enzymes or from retained sebaceous secretions) leak in the surrounding tissue and result in granulomatous inflammatory response.
On clinical examination, single nontender and firm nodule is located deep inside the eyelid as compared to hordeolum which lies more superficial and is characteristically centered on an eyelash. On everting the eye lid dilated meibomian gland and chronic inspissation of adjoining glands is seen. With pressure on the lid, the thick secretion may extrude resulting in tear debris.
Age / Sex prevalance of Chalazion
It occurs in all age groups and is common in adults.
A chalazion usually develops secondary to blockage in a meibomian gland because of an infection, such as a meibomian stye (internal hordeolum) or rarely, an abnormal growth, such as a tumor.
Chalazion presents itself by following signs and symptoms:
• Painful swelling on the eyelid.
• Eyelid is tender to touch.
• Sensitivity to light.
• Increased tear formation.
Diagnosis of chalazion is based on following tests:
• Physical examination of the eyelid.
• If the blockage of Meibomian gland duct is caused by a skin cancer, biopsy is needed.
A chalazion often disappears within a month or so without treatment. If it doesn’t then following treatment may be considered:
• Application of warm compresses for 10-15 minutes at least 4 times a day.
• Surgical removal in case the chalazion continues to grow in size.
• Antibiotic eye drop is used several days before and after surgical removal of the chalazion.
Prognosis is good. Symptoms respond well to treatment. Mostly chalazion heal on their own.
Chalazion can cause astigmatism by putting pressure on cornea.
