Study Notes
Learning Outcomes
- Describe signs and symptoms of eyelid problems.
- Make definitive diagnoses and list differential diagnoses.
- Manage various eyelid issues appropriately.
Congenital Eyelid Problems
- Coloboma: Notch or gap in eyelid; risk of keratitis; correction often delayed.
- Trichiasis: Lashes directed towards the eye; can lead to irritation and scarring; treatments include mechanical methods, electrolysis, or laser.
- Distichiasis: A second row of eyelashes; congenital form associated with ptosis; treatment options include epilation or surgery.
- Epicanthus: Semilunar skin folds at the inner canthus; common in Asians, usually resolves in early childhood.
- Epiblepharon: Skin override at lid margin causing lashes to rub cornea; often resolves with age.
- Ptosis: Abnormal lid position; causes include congenital maldevelopment or acquired factors like myasthenia gravis; managed surgically when affecting vision.
Degenerative Eyelid Problems
- Dermatochalasis: Age-related skin redundancy; may require surgery if vision is impacted.
- Ectropion: Lower lid turning outward, common in elderly; causes exposure keratitis; surgical intervention recommended.
- Floppy Eyelid Syndrome: Characterized by lax eyelids; associated with sleep apnea; evaluation required.
Inflammatory/Infectious Conditions
- Blepharitis: Inflammation of eyelid margins; can disrupt tear film; linked to meibomian gland dysfunction.
- Hordeolum: Staphylococcal infection of eyelid glands; presents with pain; treated with warm compresses and antibiotics.
- Chalazion: Chronic inflammation of sebaceous glands; usually painless; may require surgical excision if large.
- Contact Dermatitis: Common in eyelids due to thin skin; avoidance of irritants is critical.
- Entropion: Inward turning of the lid margin; may require surgical management.
- Lagophthalmos: Incomplete eyelid closure; associated with facial nerve issues; must protect the cornea.
Tumors
- Benign Tumors: Include naevi (melanocytic), haemangiomas, and papillomas; commonly excised.
- Xanthelasma: Yellow patches from lipid deposits; typically benign, but systemic evaluation may be warranted.
- Actinic Keratosis: Precursor to squamous cell carcinoma; linked to sun exposure; treatable via cryotherapy.
-
Malignant Tumors:
- Basal Cell Carcinoma: Most common; typically arises on lower lid, slow-growing and locally invasive.
- Squamous Cell Carcinoma: Slow-growing; can metastasize; often found on lower eyelid.
- Sebaceous Gland Carcinoma: More aggressive, with higher metastasis risk.
- Malignant Melanoma: Rare on eyelids; most pigmented lesions are not melanoma.
- Kaposi's Sarcoma: Associated with immunocompromised patients; presents as red-to-purple lesions.
Injuries
- Types include blunt trauma, rupture, and laceration.
General Management Notes
- Surgical intervention is a common treatment for many eyelid issues.
- Maintain vigilance for corneal health, especially in conditions with irritation or exposure risks.
