Fusarium Keratitis Update

The Centers for Disease Control and Prevention (CDC) is continuing its investigation on the multi-state outbreak of Fusarium keratitis that may be associated with contact lens use. 

As of May 12, 2006, CDC has received reports of 122 confirmed cases, 15 possible cases and 60 cases still under investigation from 33 U.S. states and territories. 75 reports include insufficient evidence to classify them as cases or carry other non-Fusarium diagnoses.  States or territories with at least 1 confirmed or possible case include: AR, AZ, CA, CT, FL, GA, IA, IL, KS, KY, LA, MA, MD, MI, MO, NC, ND, NJ, NY, OH, OK, PA, PR, TN, TX and VT.  States where all cases are currently under investigation include: IN, MN, MS, NV, OR, RI, and VA.  Recent increases in confirmed cases largely reflect reclassification of existing reports that had been under investigation; reports to CDC are continually being investigated as they are identified.

The risk of getting fungal keratitis from contact lenses remains extremely low. Contact lens wearers who experience unusual redness, pain, tearing, light sensitivity, blurry vision, discharge or swelling should consult their doctor immediately.

CDC is continuing its investigation into identifying whether there are specific factors that may have placed people at risk for developing fungal keratitis, including hygiene practices, overnight contact lens wear and specific solutions used. The CDC will provide more information as it becomes available.
