The occurrence of floaters indicates vitreous opacification, where the vitreous body is affected by the pathological changes of the surrounding tissues, such as degeneration, bleeding, and exudation. This is known as vitreous opacification, also referred to as floaters, characterized by vitreous clouding, liquefaction, and the formation and contraction of fibrous membranes. In general, floaters in elderly people are mostly related to age-associated vitreous liquefaction. For myopic patients, particularly those with high myopia, a sudden onset of floaters or an increase in the number of opacities, accompanied by flashes of light, should raise concerns for potential retinal tears or retinal bleeding. It is essential to seek medical attention promptly and have a retinal examination performed by a doctor for diagnosis. Therefore, if the retinal condition is good and the floaters are merely due to vitreous liquefaction, one should overcome psychological stress and deal with it rationally. If the aforementioned retinal pathologies occur, one should immediately follow the doctor's advice to avoid delaying treatment.
