Plant vs. Cornea


This video snippet shows a remarkable case of linear abrasions from the spines of a plant leaf. The first teaching point here is that trauma involving vegetative matter can lead to a fungal infection and should be on the differential if an ulcer develops.  Secondly, it is important to follow long-term for possible recurrent erosion syndrome. Finally, trauma of any kind can lead to corneal neuropathic pain (NP). NP is much more common with post-refractive surgery like LASIK, or PRK, but early identification and treatment from any trauma is key to prevent progression to central NP.

Of course, what would one of my blog posts be without some mention of dry eye… so, if the patient has underlining asymptomatic dry eye, a trauma like this can trigger symptomatic dry eye and thus aggressive dry eye therapy may be indicated.
