Case #224 - March, 2008

A 47-year-old male with travel history to the Galapagos Islands, Ecuador and Colombia presented to his health care provider with follicular conjunctivitis. A worm-like object measuring approximately 3.0 mm was removed from his eye and sent to a pathology laboratory for analysis. The object was sectioned, stained with hematoxylin and eosin (H&E) and examined microscopically. Figure A shows the object at 40x magnification; Figure B shows a close-up of one end of the object at 100x magnification. What is your diagnosis? Based on what criteria?
