3. Learning Outcomes
At the end of lecture, you are able to understand:
• Aetiology of chalazion
• Clinical features of chalazion
• Fate of chalazion
• Complications of chalazion
• Treatment of chalazion

4. Chalazion is
chronic sterile
inflammatory
lipogranuloma
of the Meibomian
Gland.

5. Aetiology
• Obstruction of orifice of Meibomian gland by:
> infection
> Unknown cause
• Accumulation of sebaceous secretion within acini of gland.
Precipitating Factors:
1. Blepharitis
2. Diabetes mellitus
3. Seborrhoea

6. Clinical features
• More in upper eyelids
> No. Of Meibomian glands
are more in upper eyelids
• Painless gradually increasing
swelling
• No external signs of acute
inflammation
• Small nodule on palpation
• Eversion shows red or reddish
yellow conjuctiva over nodule
• Blurred vision due to astigmatism

7. Fate of chalazion
1. Spontaneous complete resolution
2. Liquify to form thin fibrous sac containing glairy fluid
called Meibomia/chalazion cyst .
3. Fibrosed into hard nodule
4. Calcification
5. Infection and suppuration
6. Burst and present as fleshy mass

8. Complications
• Mechanical ptosis
> mechanical weight of chalazion
• Astigmatism and blurring of vision due to
> mechanical pressure over 12’o clock position of
cornea

9. Differential diagnosis
1. Sebaceous gland adenoma
2. Sebaceous gland carcinoma
3. Sarcoid granuloma
4. Dermal tuberculosis
5. Fungal infection
6. Foreign body granuloma

10. Treatment
1. Conservative
• Expression compression
• Warm compress
• Topical steroid-antibiotic combination drops
• Topical anti-inflammatory drops
2. Medical
• steroid injection (Triamcinolone acetonide)
• Systemic antibiotics
