Phylectenule Infection on Cornea (Photo)

This photograph of the eye shows a small phylectenular bump. The slit-beam light passes through it and illustrates the raised nature of this lesion.

Phylectenules are generally harmless, though irritating. They are though to be a hypersensitivity reaction to antigens such as those produced by Staph bacterial with bad blepharitis infection. To get a better idea how this bump looks under the microscope, view our phylectunule of cornea video from which this picture was taken.
