Sudden flashing sensation and wave pattern in the eyes may be caused by posterior vitreous detachment, or it may be caused by retinal tear, retinal detachment and other lesions.
Posterior vitreous detachment mainly refers to the detachment between the posterior border membrane of the vitreous body and the retina. During the detachment process, the two pull each other, which can cause a flashing sensation and the appearance of wave ripples. Posterior vitreous detachment is mostly seen in middle-aged and old people and patients with high myopia, often accompanied by vitreous liquefaction, which usually requires no special treatment.
Retinal cracks, retinal detachment and other lesions may also cause flashes of light and waves, which may have a serious impact on vision, and need to go to the hospital in a timely manner, and be treated with medication or surgery according to the relevant principles of treatment.
It is recommended that patients go to the hospital in a timely manner to clarify the cause of the disease and follow the doctor’s instructions for treatment.
