Signs of chalazion (meibomian cyst)
|
|
Painless, roundish, firm lesion |
May rupture through conjunctiva |
within tarsal plate |
and cause granuloma |
|
|
Histology of chalazion
Multiple, round spaces previously |
Epithelioid |
Multinucleated |
containing fat with surrounding |
cells |
giant cells |
granulomatous inflammation |
|
|
|
|
|
Treatment of chalazion
|
|
|
Injection of local anaesthetic |
Insertion of clamp |
Incision and curettage |
|
|
|
Acute hordeola
Internal hordeolum |
External hordeolum (stye) |
|
( acute chalazion ) |
||
|
•Staph. abscess of meibomian glands
•Tender swelling within tarsal plate
•May discharge through skin
or conjunctiva
• Staph. abscess of lash follicle and associated gland of Zeis or Moll
•Tender swelling at lid margin
•May discharge through skin
Molluscum contagiosum
Signs |
Complications |
• Painless, waxy, umbilicated nodule |
• |
Chronic follicular conjunctivitis |
• May be multiple in AIDS patients |
• |
Occasionally superficial keratitis |
Histology of molluscum contagiosum
•Circumscribed lesion
•Surface covered by normal epithelium except in centre
•Lobules of hyperplastic epithelium
•Intracytoplasmic (Henderson-Patterson) inclusion bodies
•Deep within lesion bodies are small and eosinophilic
•Near surface bodies are larger and basophilic
Xanthelasma
•Common in elderly or those with hypercholesterolaemia
•Yellowish, subcutaneous plaques containing cholesterol and lipid
•Usually bilateral and located medially
Eyelid cysts
Cyst of Moll |
Eccrine sweat gland |
|
hidrocystoma |
||
|
• Translucent |
• Similar to cyst of Moll |
|
• On anterior lid |
• Not confined to lid |
|
margin |
margin |
|
|
|
|
Cyst of Zeis |
Sebaceous cyst |
|
• Opaque |
• Cheesy contents |
• On anterior lid |
• Frequently at |
margin |
inner canthus |
