Title: 1. Cicatricial pemphigoid
1IMMUNOBULLOUS DISEASES
1. Cicatricial pemphigoid
2. Stevens-Johnson syndrome
3. Toxic epidermal necrolysis (Lyell disease)
4. Epidermolysis bullosa
5. Pemphigus vulgaris
6. Linear IgA bullous dermatosis
2Cicatricial pemphigoid
- Typically affects elderly women
- Increased prevalence of HLA-B12
Oral mucosal lesions in most cases
Skin lesions are less common
3Progression of ocular cicatricial pemphigoid
Diffuse hyperaemia
Pseudomembrane formation
Symblepharon
Subepithelial fibrosis and shrinkage
4Complications of ocular cicatricial pemphigoid
Ankyloblepharon
Cicatricial entropion
Metaplastic lashes
Corneal keratinization
Total obliteration of fornices
Secondary bacterial keratitis
5Stevens-Johnson syndrome
- Hypersensitivity to drugs or infection
- Typically affects young men
Lesions of oral mucosa and lips
Vesciculobullous haemorrhagic and necrotic lesions
Maculopapules which may develop into target
lesions
6Ocular complications of Stevens-Johnson syndrome
Transient conjunctivitis and lid crusting
without sequelae
Severe membranous or pseudomembranous
conjunctivitis
Focal fibrotic patches and occasionally
symblepharon
Metaplastic lashes
7Other immunobullous diseases (1)
Toxic epidermal necrolysis (Lyell disease)
Epidermolysis bullosa
- Skin bullae and necrosis induced by
- minor trauma
- Conjunctivitis - common and similar to
- Stevens-Johnson syndrome
- Conjunctivitis - common and may result
- in scarring
8Other immunobullous diseases (2)
Pemphigus vulgaris
Linear IgA bullous dermatosis
- Tense bullae of varying size
- Conjunctivitis - common and may result
- in scarring
- Conjunctivitis - uncommon and mild
