Aedes aegypti is caused by vitreous clouding, which is generally caused by aging factors that result in the formation of point-like, flocculent, or clump-like turbidity inside the originally transparent vitreous tissue, and the turbidity will block the refraction of light, resulting in shadows cast on the retina, and the patient will feel mosquito-like shadows fluttering in his or her field of vision. Since aging is irreversible, Aphakia does not go away on its own. The discomfort of Aedes aegypti may worsen with age, but patients may gradually adapt to the appearance of dark shadows in front of their eyes. If the symptoms of Aedes aegypti are obvious, patients can take oral lecithin complex iodine tablets and other medications under the guidance of the doctor to promote the absorption of cloudy vitreous humor and improve vision. It is recommended that patients with obvious symptoms of FMS should consult a doctor in time to evaluate their condition and follow the doctor’s instructions for treatment.
