Floaters, medically known as “vitreous opacity”. When it occurs, the patient’s eyes appear as dots, lines, strips and other shadows fluttering, and some patients feel that there are mosquitoes flying in front of them, which is called floaters as the name suggests. Patients can have the disease in one eye or both eyes. Clinically, floaters are divided into physiological floaters and pathological floaters. Physiological floaters are mostly caused by degenerative diseases such as vitreous degeneration and liquefaction. Pathological floaters are mainly caused by vitreous inflammation, retinal detachment, and intraocular tumors. Most people get floaters. For middle-aged and elderly patients over forty or fifty years old, due to the obvious vitreous liquefaction, the liquefaction is aggravated when the body or eyes are fatigued, or during strenuous exercise or physical activity, and floaters are prone to occur. People with myopia, especially those with high myopia, are more likely to get floaters. Most of the myopia is axial myopia, which means that the longer the eye axis, the higher the degree, the larger the eyeball, but the volume of the vitreous body is limited, so the vitreous body of patients with high myopia is more likely to liquefy, showing more obvious floaters. Others, such as eye trauma, diabetes, hypertension, uveitis, and fundus diseases, are also more prone to floaters. (Science China, Zeta)
