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
- Pain, photophobia, foreign body sensation, decreased visual acuity, discharge, and burning are common.
Differential Diagnosis
Contact lens wearers are at increased risk of:
- Infectious corneal infiltrate or ulceration
- bacterial(pseudomonas in particular), fungal, and acanthamoeba
- Keratoconjunctivitis
- Hypersensitivity to contact lens solution
- often secondary to a new solution or inadequate lens rinsing
- Contact lens induced Giant Papillary Conjunctivitis
- Allergic conjunctivitis
- Corneal edema, distortion
- Sterile infiltrates
- Neovascularization
- Displaced contact lens
- if displaced it is usually in the superior fornix
