Fusarium-A New Culprit in the Contact Lens Case

摘要

MICROBIAL KERATIT1S IS A VISION-THREATENING infection of the cornea caused by different infectious agents including viruses, bacteria, fungi, and protozoa. Risk factors for infection with nonviral agents include trauma, contact lens wear, and chronic ocular surface disease. In the United States, the incidence of comeal ulceration is about 11 per 100 000 person-years,1 and contact lens wear is the most important risk factor. In developing countries, such as those in South Asia, ocular trauma is the principle risk factor for infectious kerati-tis.2'3 Furthermore, the annual incidence of infectious kerati-tis in South Asia appears to be from 10 (113 per 100000 persons)~4 to 70 (799 per 100 000 persons)~5 times greater than in the United States
