Entropion is the turning inward of the eyelid
causing the eyelashes to rub against the eyeball
proving to be very irritating and eventually even
painful. If not corrected this problem could cause
mucus discharge and significant corneal damage. Entropion could be caused by aging allowing the
eyelid muscles and tendons to become lax. It could
also be caused by scarring of the inside of the
eyelid secondary to trauma or previous infection.
There are various surgical techniques to correct
this problem involving tightening of the lower
eyelid and reattaching the lower eyelid muscles.
The basic premise here is likening the lower eyelid
to a tennis net that is too loose and falls inward.
If the problem is due to scarring from previous
trauma or infections then the scarring would need to
be addressed by grafts to vertically lengthen the
scarred shortened lower eyelid.
