The appearance of flies in front of the eye can be due to several reasons. This is a neurologist from JSC “Medicina” (Academician Roitberg clinic), Dr. Said by Galina Chudinskaya.
A common cause is high or low blood pressure. In this case, it is important to consult a specialist to choose the appropriate treatment.
Flies in the front of the eye can also occur with damage to the vessels of the eye, such as retinopathy. Symptoms of retinopathy include blurred vision, large spots in the field of view, and flies before the eyes. Prompt treatment can reduce these symptoms and prevent vision loss.
Also, flies can be the result of inflammation of the vascular membranes of the eye or retina, or of both structures at the same time. Patients may also notice flashes of light and have trouble seeing in the dark. In some cases, infectious diseases can even cause blindness.
If the flies in the eye are accompanied by sparks, flashes, decreased visual acuity and a feeling of clouding in the eyes, it may be due to separation of the vitreous and retina. In such cases, it is important to consult a doctor to avoid possible complications.
Chudinskaya emphasized that it is important to seek medical help in case of flies before the eyes in order to prevent possible complications, including blindness. Particularly high risk of vitreous and retinal detachment in people with myopia. She also noted that flies and other vision problems may be associated with impaired blood flow in the arteries of the spine in osteochondrosis of the cervical spine.
