Aedes aegypti includes physiologic and pathologic conditions. Physiologic Aedes aegypti usually requires no treatment; pathologic Aedes aegypti requires medication according to the condition, usually not using oral medication, often using injectable preparations. Aedes aegypti manifests itself in the form of floating black shadows in front of the eyes, which may be accompanied by a flashing sensation. Physiologic Aedes aegypti is caused by age-related changes in the vitreous humor, which is common in myopic people and the elderly, and usually requires no treatment. The common causes of pathologic Aedes aegypti include vitreous hemorrhage and vitreous infection. If it is caused by vitreous hemorrhage, hemostatic drugs such as hydroxybenzenesulfonyl ethylamine and atenosine can be used as injectable preparations. If it is due to infectious vitritis, intravitreal and subconjunctival injections are feasible, and antibiotics such as ceftazidime and vancomycin are used. Usually, oral preparations are not used for the treatment of flying mosquitoes, and it is recommended to consult a doctor in a timely manner and follow the doctor’s instructions for medication.
