Discussion
Previous reports showed tick infections could be located on the
conjunctiva or eyelid.[2] Ticks are known to
transmit numerous infectious diseases to humans, such as Lyme disease,
Leptospira, scrub typhus and Q fever. In this case, we report a
48-year-old chicken-raising woman who presented with a gray tick on her
itched upper eyelid, which may be related to her close contact with
chickens. She was found redness, swelling and itching of the upper
eyelid after being bitten by a tick. Fortunately, the patient did not
deal with it by herself, and she asked for ophthalmologists. The tick
was removed intactly, and the patient did not have fever, diarrhea, or
other system symptoms.
Patients with tick infestation should
see a doctor immediately. In addition, in order to prevent tickborne
disease, removal of the tick from the affected tissue completely is
important. Tick attached skin closely which is not easy to be pulled
out. Pulling out tick directly could induce breakage of tick and
secondary damage of the skin. Therefore, local anesthetic can be applied
to the head of tick. The careful, mechanical extraction of ticks using
fine-tipped tweezerst is safe and effective.[3, 4]When the tick naturally falls from the skin, the wound should be
disinfected immediately. If its mouth is broken, it should be removed by
operation.After removal of ticks, the patients should undergo hemogram,
biochemical and serological tests. The local eye diseases and systemic
symptoms caused by tick infection should be excluded during clinical
observation and follow-up. [5, 6]
