corneal ulcer/hypoxia

We report six cases of corneal complications observed in disposable extended-wear contact lens users: two corneal ulcers, one superficial infiltrate, two punctate keratitis with subepithelial infiltrates and one superficial punctate keratitis. In four cases a bacterial etiology was confirmed.

OBJECTIVE The relationship between overnight contact lens wear and infectious corneal ulcers has been widely reported. Corneal hypoxia during sleep with contact lenses is believed to be an important predisposing factor for infectious corneal ulcers. We designed a provocative test to identify corneas

OBJECTIVE To report a case of Pseudomonas aeruginosa culture-positive microbial keratitis in a patient wearing continuous-wear silicone hydrogel soft contact lenses. METHODS A 23-year-old white woman in good health had been wearing silicone hydrogel (lotrafilcon A) soft contact lenses continuously

Various risk factors contributing to contact lens related infectious corneal ulcers were tested. These factors included the presence of infectious organisms, loss of corneal surface integrity, and corneal hypoxia. High concentrations of Pseudomonas bacteria were applied to rabbit corneas under the

Common types of contact lens are hard, rigid gas-permeable or soft lenses. Most lenses are worn on a daily basis. Cosmetic lenses are worn for non-medical indications. Microbial keratitis, a rare but most significant complication is discussed in this article. Pseudomonas aeruginosa and staphylococci

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used agents that despite chemically heterogeneity, share similar therapeutic properties and adverse effects. Topical ophthalmic NSAIDs are limited to the relatively water soluble phenylacetic and phenylalkanoic acids as well as indole
