Causes of hyperthyroidism proptosis: 1. The action of thyroid hormones leads to hyperplasia of the extraocular muscles. Hyperthyroidism proptosis occurs due to thickening and increased tone of the levator muscle. Genetic factors: Human cytocompatibility antigen is closely related to proptosis, and the number of patients with hyperthyroidism with positive HLABgDR3 loci is significantly higher than that of hyperthyroidism without proptosis. 3, environmental factors: observation of hyperthyroidism patients, found that 83% of those with proptosis smoked, while only 40% of those without proptosis smoked, suggesting that smoking may be involved in the occurrence of proptosis. This is one of the causes of hyperthyroidism proptosis. 4, the role of posterior fibroblasts: immunohistochemical staining showed the presence of IGF-I in extraocular muscles, adipocytes, and inflammatory infiltrating cells, while IGF-I and fibroblast generating factor have the role of stimulating fibroblasts. Therefore, the cause of hyperthyroidism is related to this. The most important thing is to prevent hyperthyroidism. If the eye is not normal, you should actively observe it and go to the regular hospital for examination in time to avoid all eye diseases. After the discovery of hyperthyroidism proptosis, patients need timely treatment. In the treatment of thyroid disease, the Second Hospital of the Armed Forces Beijing adopts the “TG glandular micro-conductor balancing treatment system”, which has effectively treated many patients with thyroid disease, helping them to get out of the disease and restore their health. In order to prevent keratitis and conjunctivitis, antibiotic eye ointment, methylcellulose eye drops or hydrocortisone eye drops can be used to spot the eyes, Xu eye ointment before bedtime and cover with clean gauze. Cover and elevate the head during sleep. To reduce eye swelling. Also, diet should be taken care of. Diet is something that patients need to pay attention to. Patients must pay attention to a light diet and limit the intake of water and salt to avoid aggravating the protrusion of the eye, which is the key point of care for hyperthyroidism proptosis. Spicy and stimulating foods are prohibited and alcohol should be consumed sparingly. These foods have a pushing effect on the aggravation of hyperthyroidism-related ophthalmopathy. In daily life, patients also need to strengthen their eye exercises. Strengthening eye exercises for hyperthyroidism proptosis is also good for the condition. Generally speaking, patients with severe diplopia can use unilateral eye shields to reduce diplopia, do eye exercises every day to exercise the eye muscles and improve the function of the eye muscles, but try to avoid gazing upwards to avoid aggravating the protrusion of the eye and inducing strabismus, and when the extraocular muscles are involved, it is best to cover one eye.
