Vitreous turbidity is a common ophthalmic condition, mainly manifested as mosquitoes, patients can see dots, strips, mesh and other forms of vague shadows floating in front of the eyes, especially when looking at bright places. Vitreous turbidity can be divided into pathological and physiological.
Pathological vitreous clouding is one of the manifestations of eye diseases, such as diabetic retinopathy, uveitis, retinal detachment and vitreous hemorrhage. The first need to treat the primary disease, only in the primary disease has been controlled on the basis of treatment of vitreous turbidity will be improved, otherwise the treatment of vitreous turbidity is meaningless, can not achieve the purpose. Commonly used drugs are propidium iodide injection or antoiodine injection, once a day, 10 times a course of treatment, each course of treatment interval of one or two weeks, generally with 2 to 3 courses of treatment.
In the case of early active standardized treatment, the effect of most patients is still relatively satisfactory. However, if the time has been a year and a half, because the vitreous body has produced proliferation, mechanization, these larger, more obvious vitreous clouding can not be eliminated by drugs, and some will continue to aggravate. When it pulls on the retina, it can easily cause retinal detachment, at which point it is necessary to perform a vitrectomy, otherwise vision loss.
Physiological vitreous clouding is a degeneration caused by vitreous dystrophy, for vitreous liquefaction, degeneration, common in high myopia and the elderly. When the vitreous atrophy reaches a certain level, it will separate from the posterior part of the eye, called posterior vitreous detachment, and then there will be a ring-shaped clouding where it was originally attached to the optic papilla, which is also a common condition of vitreous clouding in many elderly people.
The aging of the vitreous cannot be reversed, but if you are still young and want to use medication to give nutrients and slow down the vitreous decline, you can use ophthalmic aminoglutethimide injection for two weeks. The next course of treatment should be continued at intervals of one course. It is not effective in promoting the absorption of vitreous opacities when used in the presence of vitreous opacities.
For adjuvant therapy can be carried out to dilate blood vessels, increase microcirculation, and promote the absorption of vitreous turbidity, such as thromboxane, ginkgo biloba, etc., again, can only promote the remission of anti-inflammation, absorption of bleeding, can not improve the state of vitreous proliferation, mechanization, these only surgery.
Regarding the surgery of vitreous turbidity, in addition to the conventional vitrectomy, in recent years the laser treatment of vitreous turbidity equipment was introduced. The laser vaporizes the substance so that it can be absorbed. However, this is only applicable to lesser vitreous opacities, and if the vitreous cavity is heavily clouded, conventional surgery still cannot be replaced at this time.
