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]
