The inside of the eyelids and
the surface of the eye respond to irritation by becoming red and
swollen with tearing and mucous discharge. If the irritant produces
release of immune cells, the reaction is called an allergic process
and is accompanied by itching. One person might be more sensitive than
another to certain irritants or allergens. One person might be more
sensitive at one time than another. That is why there is such a
variation in allergic reactions.
There are several degrees of
allergic response of the eyes. Treatment is directed to the degree of
response with the purpose of providing relief in the simplest, safest,
most convenient and cost effective manner.
Redness and itching on some
days, with minimal tearing, mark the initial allergic response.
Seasonal presentation is common. Nose irritation and sneezing may
accompany the eye symptoms. Treatment is cool or cold compresses to
prevent rubbing. A damp cloth kept in a plastic bag in the
refrigerator is an easy way to provide cool compresses. An
antihistamine/decongestant eyedrop also is helpful. There are many
brands available over the counter; all of them end with an “A”
at the end. Some examples include: Vasocon A, Naphcon A,
Albalon A or Visine AC.
Mid levels of allergic response
presents with daily itching and burning of the eyes, excess tearing
and redness, worse in the afternoons. Some degree of light sensitivity
is common. Treatment is the cool compresses as above and a daily drop
to prevent the release of the allergic chemicals inside the eyelids.
The drops must be used on a regular basis to prevent the release of
these chemicals inside the eyelid. It takes several days for the
effect of the drop to build up. The effect disappears when the drops
are stopped. Drops should be continued until a seasonal change of
climate. Examples of such prescription medications include:
Patanol, Acular, Alocril, Livostin,
Opticrom, Zaditor and Optivar.
Severe degrees of reaction cause
changes in the structures of the eyelids and can be sight threatening.
These reactions are treated with prolonged topical steroid medicines
and systemic medicines. A severe form, TENS or Steven Johnson
syndrome, can affect all parts of the body and is life threatening in
severe cases. Prolonged use of topical steroids carries risks of
glaucoma, cataracts and visual loss.
