Conjunctival edema caused by a patient’s eye getting into a worm may be caused by irritation of the conjunctival edema due to the worm or toxin secretion from the worm. Patients can remove the worm, clean the conjunctival sac and medication to promote the edema to subside. Worms entering the conjunctival sac can cause irritation, and patients need to avoid rubbing their eyes, which can lead to aggravation of conjunctival edema. Patients can use saline to rinse the conjunctival sac or use tweezers to clip out the bugs, thus relieving eye discomfort. If the patient’s conjunctival edema, congestion, stinging discomfort is obvious, the patient can first apply a local cold compress to relieve discomfort. Patients can also follow the doctor’s instructions to use levofloxacin eye drops, tobramycin eye drops and other medications to control inflammation and promote recovery. It is recommended that patients who have worms in their eyes and experience significant discomfort seek prompt medical attention to assess their condition and treat them under the guidance of a doctor.
