Study Notes

Blepharitis

Primary cause includes seborrheic dermatitis and dysfunction of meibomian glands.
Characteristic sign is flakes and crusts at the base of eyelashes.
Recommended frequency for eyelid cleaning is at least once daily.
Goal of treatment is to reduce inflammation and manage symptoms.
Complications such as eyelid infections may require oral antibiotics.

Styes

Typical treatment includes warm compresses to promote drainage and relieve discomfort.

Conjunctivitis

Characteristic symptom includes redness and discharge from the eye.
Commonly affects children but can occur at any age.
Key difference: Bacterial conjunctivitis often has thick, yellow discharge, while viral conjunctivitis typically has watery discharge.

Subconjunctival Haemorrhage

Typical symptom is visible red patch on the white part of the eye.
Recommended course of action without trauma history is observation; usually resolves on its own.
Recurrent incidents may indicate hypertension or bleeding disorders.

Glaucoma

Mechanism involves increased intraocular pressure, leading to optic nerve damage.
Normal function of the trabecular meshwork is to drain aqueous humor and regulate eye pressure.

A small, usually painful lump on the eyelid is referred to as a stye.
