Vascular opacities are more common in joints and corneas. The causes of formation of vascular opacities in different parts of the body vary and treatment differs, mainly in the following two ways. 1. Vascular opacities in joints are associated with rheumatoid arthritis and ankylosing spondylitis, which are specific inflammatory conditions that cover the surface of bones and prevent them from absorbing nutrients from soft tissues such as synovium, leading to ischemic necrosis of cartilage, etc. 2. The main treatment is to treat the primary disease, such as controlling rheumatoid arthritis and ankylosing spondylitis, while treating the symptoms caused, such as ischemia with blood activation, pain with pain relief, etc. 2, corneal opacity, the cornea itself has no vascular tissue, once there is a blood vessel invasion of the cornea will form a corneal opacity, which will gradually affect vision until blindness. The treatment is to avoid rubbing the eyes as much as possible, and to improve the symptoms with eye drops. Surgery is not possible after improvement, but the efficacy is poor, the treatment is very difficult, and the failure rate of surgery is very high with less than ideal results, so try to detect and treat early. Therefore, the treatment of vascular opacification is basically based on treating the primary disease and trying to control the symptoms to improve the condition.
