Depending on the etiology of vitreous clouding in the eye, vitreous clouding is generally classified into physiological vitreous clouding and pathological vitreous clouding. Physiological vitreous clouding is caused by the projection of embryonic remnant cells or blood cells in the vitreous humor onto the optic cell layer as they travel through the retinal vessels, and has no effect on vision. Because the residual cells are very small, the cloudy material is not easily detected with the ophthalmoscope and is not an eye disease. In contrast, pathological vitreous turbidity is often accompanied by a variety of fundus complications and requires timely treatment. The treatment methods are: 1, drug treatment. First of all, we should examine and do treatment for the cause. If inflammatory, it is appropriate to treat the pathogen, if necessary, local or systemic corticosteroids; for early thrombosis can try anticoagulation therapy. However, the prothrombin time should be checked regularly and the systemic bleeding should be alerted. In recent years, various enzyme preparations (hyaluronidase, streptokinase, urokinase, etc.) have been applied at home and abroad to treat relatively old bleeding in the eye. However, the effect on thick old vitreous turbidities and blood clots is also unsatisfactory, and one should always be alert to circumferential hemorrhage and systemic fever and adverse hepatic and renal function. Therefore, surgery is still sometimes required for such clouding at present. In order to strengthen the body and promote absorption, the whole body is also often used iodine, calcium.
2.Physical therapy. Including ultra-short wave, ultrasound and sodium iodide iontophoresis have long been applied. In recent years the use of laser treatment, some cases are effective, but to have a good grasp of the indications and do further observation.
3.Surgical treatment. For longer, thicker, the application of internal therapy can not be absorbed, especially the formation of mechanized film has a tendency to traction retina, should promptly consider surgical treatment, but for the unstable condition prone to re-bleeding, such as diabetic, etc., vitrectomy should be performed.
