Pre-macular membranes can affect a patient’s vision but generally do not cause blindness. If a patient’s disease continues to progress with proliferation, contraction, and pulling of the pre-macular membrane, it can cause macular damage and may lead to blindness. Pre-macular membrane is a dense, fibrous, membranous structure that occurs in front of the retina due to a variety of reasons and is closely associated with the retina as a result of cell proliferation. Without surgical removal of the proliferating macular prefovea, or if the cause of the disease is not resolved, the continued development of the prefoveal membrane fibrous membrane contraction on the retina produces tension, which can cause damage to the macula, impairing the patient’s vision, and even blindness. Pre-macular membrane may be due to physical blockage, slight pulling, etc., leading to blurred vision and distorted vision and other uncomfortable symptoms. Pre-macular membrane that seriously affects the patient’s vision needs timely surgical treatment to improve vision. It is recommended that patients with macular precursor should consult a doctor in time to evaluate their condition and follow the doctor’s instructions for treatment.
