Case of the week: Trichiasis
Trichiasis is the inward turn of eyelashes. We see this pretty commonly in the clinic. The primary symptoms are foreign body sensation and irritation.
The easiest treatment is epilation (removal of the lash/lashes involved). Typically the lashes will regrow in a couple months and need to be removed again. Also, contact lenses can be used to protect/shield the cornea from the lash. A more permanent treatment option would be destruction of the follicle. This can be achieved by electrolysis or cryotherapy. Electrolysis uses electric current to destroy the follicle whereas cryotherapy uses extreme cold temperature to destroy the follicle.
The photo below is a current patient who is being referred for one of these procedures. We have epilated the single lash 4-5 times over the past 10 months. You can see where the lash has caused several scratches/epithelial corneal defects from constant tracking across the eye. The cornea heals quickly once the lash is removed.
