WHAT CAUSES ECTROPION?
Ectropion is usually due to relaxation of the
tissues of the eyelid as a result of ageing changes.
Therefore, it is most often seen in elderly people
who develop stretching of the structures supporting
the lower eyelid.
It can also arise as a result of undetected skin
cancers pulling down the eyelid, trauma, contraction
of scar tissue (from wounds, burns or surgery),
and following eyelid or facial surgery.
Ectropion may develop following facial nerve palsy
(Bells palsy), in which the muscles surrounding
the eye (and other facial muscles on that side
of the face) are paralysed. Finally, ectropion
may be further aggravated due to constant wiping
by the tearing patient, which tends to pull the
eyelid further from the eye.
WHAT ARE THE SYMPTOMS OF ECTROPION?
Ectropion can cause chronic irritation to the
eyelid and the eye. This can result in excessive
tearing, crusting of the eyelid and mucous discharge,
infection, irritation of the cornea, and impaired
vision.
When the lower eyelid is turned outward and no
longer touches the eye, it cannot properly spread
the tear film across the eye, which leads to poor
drainage of tears through the nasolacrimal (tear
drainage) system.
The exposed inner lining of the eyelid becomes
dry and inflamed. As a result, the eye may become
damaged.
HOW IS ECTROPION TREATED?
To prevent dryness of the cornea because the tear
film does not properly lubricate the eye, artificial
tears and lubricating ointments may be used to
keep the cornea moistened. A protective shield
may be worn at night to keep moisture in the eye.
However, the majority of ectropion are treated
surgically. The best method of ectropion repair
often depends on the underlying cause. In the
'involutional' type of ectropion (associated with
ageing), Dr Martin may elect to shorten and tighten
the lower lid, thereby resolving the outwardly
turned lid. This is typically completed with an
incision of the skin at the lateral corner of
the eye. He will then excise a small segment of
the lateral aspect of the lower eyelid, and subsequently
will reconnect the eyelid to the underlying tissues
and the upper eyelid.
Ectropion which occurs as a result of scarring
(cicatricial ectropion) is most likely to follow
another surgical procedure of the face or eyelids,
especially excision of skin lesions (such as skin
cancers). This type of ectropion repair often
requires skin grafting. The donor site of the
skin graft is often taken from the upper eyelid
or from behind the ear. The skin from these sites
will most closely match that of the lower eyelid
skin.
WHAT CAN I EXPECT AFTER SURGERY?
There is typically almost immediate resolution
of the condition. Most patients have little, if
any, discomfort. Dr Martin will prescribe antibiotic
ointment and drops for your eyes (and/or graft
site). There may be mild swelling and bruising
following the procedure, however, this should
resolve within 2-3 weeks.
Usually only a few sutures are placed in the skin
at the lateral corner of the eye, and these are
often removed 7-14 days post-operatively.
If a graft was required, both the donor site for
the graft and the surgical site will usually heal
within 2 weeks following surgery.
