Flickering light spots in the eyes are considered to be caused by eye diseases such as retinal detachment and retinal schwannoma. 1. Retinal detachment: this is a more serious eye disease, mainly due to patients with eye trauma, intraocular surgery, or suffering from peripapillary retinal vein inflammation, posterior scleritis and other eye diseases. This disease often leads to symptoms such as mosquitoes, black shadows in front of the eyes, etc. At the same time, the patient will also have a sense of flash in front of the eyes, such as light spots and light spots. 2. Retinoschisis: this disease is relatively rare in the clinic, mainly due to the patient’s presence of microcystic degeneration around the retina, or due to the influence of genetic factors, resulting in the epithelial layer of the retinal nerve is split into two layers. Patients often present with symptoms such as decreased visual acuity, mosquitoes, and a flashing sensation in front of the eyes, which results in the appearance of flickering patches of light in the eyes. It is recommended that patients with recent flickering light spots in the eyes should consult a doctor in time for examination and active treatment after clarifying the cause of the disease, so as to avoid delaying the disease and affecting the eyesight.
