Chalazion
Chalazion is a chronic sterile inflammation of the eyelid resulting from a
lipogranuloma of the meibomian glands that line the posterior margins of the
eyelids (see Fig. 29-7). It is deeper in the eyelid tissue than a hordeolum and
may result from an internal hordeolum or retained lipid granular secretions.
Clinical Findings
Initially, mild erythema and slight swelling of the involved eyelid are seen.
After a few days the inflammation resolves, and a slow growing, round,
nonpigmented, painless (key finding) mass remains. It may persist for a long
time and is a commonly acquired lid lesion seen in children (see Fig. 29-7).

Management
• Acute lesions are treated with hot compresses.
• Refer to an ophthalmologist for surgical incision or topical intralesional
corticosteroid injections if the condition is unresolved or if the lesion
causes cosmetic concerns. A chalazion can distort vision by causing
astigmatism as a result of pressure on the orbit.
Complications
Recurrence is common. Fragile, vascular granulation tissue called pyogenic
granuloma that enlarges and bleeds rapidly can occur if a chalazion breaks
through the conjunctival surface.
