Vitreous clouding patients take calcium hydroxybenzenesulfonate can not reduce vitreous clouding, if the patient combined with other fundus lesions, such as diabetic retinopathy, etc., can eat. Vitreoretinal clouding is a common ophthalmic disease that occurs in middle-aged and elderly people, due to the accumulation of cellular metabolites in the transparent vitreous tissue in the form of dots, threads and clusters, which can lead to dark shadows in the patient’s field of vision. Calcium hydroxybenzenesulfonate is not effective in improving vitreous clouding, and oral lecithin complex iodine tablets can be used to reduce the clouding. If patients with vitreous clouding have diabetic retinopathy and other fundus diseases at the same time, it is possible to use calcium hydroxybenzenesulfonate to treat the fundus diseases, which has the effect of improving the blood circulation of the retina, and will not affect the condition of vitreous clouding. Specific medication should be under the guidance of a doctor. Vitreous patients are advised to go to the hospital for timely examination before receiving the correct treatment.
