Classified based on location: anterior or posterior lamella. These lesions are common and self-limiting, only rarely requiring any form of medical intervention.
Hordeolum (stye)
A painful lid abscess caused by Staphylococcus infection.
Pathology
Hordeolum is classified according to the affected gland:
- External (anterior lamella): abscess of Zeis or Moll glands
- Internal (posterior lamella): abscess of Meibomian glands
Presentation
- Painful nodule
- Commonly affects the upper eyelid
- Diagnosis is clinical
Management
- Hot compress
- Oral antibiotics
Hordeolum is frequently compared to chalazion in questions. The key differentiation is that chalazion is a painless nodule.
Chalazion
Chalazion is the most commonly occurring lid lump. It is painless.
Pathology
- Obstruction of Meibomian or Zeis glands leads to sterile lymphogranuloma formation
Presentation
- Painless upper eyelid nodule
Management
- Hot compress is the only management that is usually required
- Surgical incision and curettage is an option but rarely needed
Anterior Lamella Cysts
Cyst of Moll and Cyst of Zeis are chronic benign anterior lamella cysts. They are often self-limiting but can be excised or treated with diathermy
Cyst of Moll |
Chronic translucent cyst arising from blockage of Moll glands |
|---|---|
Cyst of Zeis |
Chronic non-translucent cysts arising from blockage of Zeis glands |
