Acyclovir sensitivity of herpes simplex virus was tested with a dye uptake assay and we found that the herpes simplex virus isolated was resistant to acyclovir. We started eye drop therapy with NGF and the corneal herpetic ulcer healed in 23 treatment days.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>The case presented here is the first described in the literature in which a herpetic corneal ulcer was successfully treated with NGF.
