Background
- Mechanisms of complications include[1]:
- Direct trauma
- Decreased corneal oxygenation
- Reduced corneal/conjunctival wetting
- Allergic/inflammatory responses
- Infection
Clinical Features
- Presentation of various problems may be complicated by hypoesthesia in chronic contact lense wearers
Differential Diagnosis
Contact lens wearers are at increased risk of:
- Bacterial keratitis, Herpes keratitis, fungal and parasitic keratitis[2]
- Keratoconjunctivitis
- Pseudomonas conjunctivitis
- Allergic conjunctivitis
- Corneal abrasion
- Corneal ulcer
- Corneal edema, distortion
- Sterile infiltrates
- Neovascularization
