Red
Eye & Eye Lid diseases:
Red
eye is the presentation of inflammation, which is the natural reaction
of the body tissues to infection, allergic reactions, physical trauma
and burns. Characteristics symptoms of inflammation are redness,
swelling & pain. Due to intimate relationship between the lid
margin and the ocular surface; pathologies affecting the eyelids
are common causes of red eye.
Blepharitis:
Generalized
inflammation of the eyelid margins, with symptomatic redness, itching
and discharge. It tends to be very persistent and may cause the
eyelashes to fall out or to turn inwards so they irritate the cornea.
Although the symptoms are uncomfortable, the condition usually is
not serious. Blepharitis is probably the single most common cause
of all eye discomfort.
Ectropion
& Entropion:
Ectropion
is eversion (turning out) of the eyelid. It can lead to poor tear
drainage and excessive exposure of the cornea due to incomplete
lid closure. Infection and damage to the cornea are more likely
to occur.
Entropion is inversion (turning out) of the eyelids so that the
eyelashes rub against the cornea. This can irritate the cornea and
make it more susceptible to infection. Eyelid abnormalities that
may encourage the development of other eye infections, such as conjunctivitis
and Keratitis. They are not infectious conditions on their own.
