Aedes aegypti is divided into physiological Aedes aegypti and pathological Aedes aegypti, physiological Aedes aegypti is mainly caused by age change. Pathological Aedes aegypti is mainly caused by vitreous blood, vitreous inflammation, intraocular tumors and other diseases.
Physiological Aedes aegypti is mainly due to age change, the original gel-like vitreous body will show signs of liquefaction, gradual dehydration and contraction, atrophy and depression, so that the vitreous body becomes viscous and uneven, when the light enters the eye, blocked by these debris, and the symptoms of Aedes aegypti will appear after the shadow is projected on the retina.
When trauma or surgery causes retinal tears, pulls small retinal blood vessels to rupture causing hemorrhage, or suffers from diseases such as retinal vasculitis, retinal vein occlusion, diabetic retinopathy, hypertension and other diseases that cause intraocular hemorrhage, and blood or exudate enters the vitreous body, the symptom of dark shadows floating before the eyes may occur, resulting in the formation of fiducial mosquitoes.
When inflammation occurs in the vitreous body or when inflammation occurs in the tissues adjacent to the vitreous body, inflammatory exudate and inflammatory cells enter the vitreous body, and vitreous clouding may occur, resulting in Aedes aegypti.
When suffering from intraocular tumors or when tumors from other parts of the body metastasize to the eye, the embryonic cells or tissues left in the vitreous body may also lead to vitreous clouding, resulting in Aedes aegypti.
If there is a mosquito, you can consult a doctor in time to find out the cause of the disease under the guidance of a professional physician, so as not to delay the condition.
