The vitreous humor is a clear gel in the eye. If an opaque body is present, it is called vitreous opacity. The normal vitreous has a tendency to degenerate with age, mainly in the form of condensation and liquefaction, which is known as vitreous opacity. However, some vitreous opacities are due to pathological causes, such as high myopia, posterior vitreous detachment, retinal detachment, uveitis, and vitreous stellate microsomes.
Patients with mild vitreous opacities feel a dark shadow moving back and forth in front of their eyes, just like a fly flying around, and it does not affect their vision. This type of clouding generally does not require treatment. While pathological vitreous turbidity is often accompanied by the emergence of a variety of fundus complications, requiring 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.
