Entropion
What is an entropion?
Entropion is the medical term used to describe
rolling inward of the lower eyelid and eyelashes towards the eyeball. The skin
of the eyelid and the eyelashes rub against the cornea (the front part of the
eye) and conjunctiva (the mucous membrane that protects the eye). This rubbing
can lead to excessive watering, crusting of the eyelid, mucous discharge, a
foreign body in the eye sensation, irritation of the cornea and impaired vision.
What are the causes for this condition?
Most cases of entropion are due to relaxation
of the tissues of the eyelid as a result of ageing. Some cases result from
scarring of the inner surface of the eyelid caused by chemical and thermal
burns, inflammatory diseases such as ocular cicatricial pemphigoid or allergic
reactions.
How is this condition managed?
Entropion should be repaired surgically before
the rubbing damages the cornea by causing infection and scarring. Prior to
surgery the eye can be protected by taping the lower lid down and using
lubricating drops and ointment. The surgery to repair entropion is usually
performed under local anaesthesia with or without sedation as a day case. In
most cases your doctor will tighten the eyelid. You may have a patch overnight
and then will commonly use an antibiotic drop or ointment for about 2 weeks.
After your eyelids heal your eye will feel comfortable, reducing the risk of
infection and loss of vision. You will have stitches that might have to be
removed.
