Allergies
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. |
