Many important fundus diseases are brought to the patient’s attention by the presence of vitreous opacities before they are seen. Vitreous turbidity is the appearance of an opaque body, a clear gel within the vitreous, that is, a cloudy body.
A. Causes of vitreous clouding
1, uveitis, inflammatory exudate and inflammatory cells into the vitreous body to form gray-white dusty, flocculent or lumpy clouding.
2, hemorrhage, due to retinal phlebitis, venous obstruction, diabetes, hypertension, trauma or surgery caused by the hemorrhage into the vitreous, in the blood into and absorption process to form red, yellow, gray-white flakes or clumps of cloudy. What are the causes of vitreous turbidity?
3, pigment, trauma, uveitis, etc. make pigment particles into the vitreous.
4, parasites and their metabolites, intraocular tumors or other parts of the body tumor ocular metastasis, causing clouding. What are the causes of vitreous turbidity?
5, eye trauma intravitreal foreign body retention.
6, due to eye trauma, hemorrhage, diabetes and other causes of intravitreal fibrous tissue hyperplasia.
Second, how to prevent vitreous turbidity
1, usually pay attention to rest do not overuse of eyes, to avoid the formation of myopia. Do not “do not turn your eyes”, pay attention to frequent and complete blinking action, often blinking can reduce the time the eye is exposed to the air, to avoid tear evaporation.
2, maintain good habits, sleep well, do not stay up late.
3, usually pay attention not to glare directly into the eyes. In addition to prevent eye trauma.
4, do not blow too long air conditioning, avoid air currents blowing over the seat, and place tea near the seat to increase the surrounding humidity.
5.Eat more various fruits, especially citrus fruits, and also eat more green vegetables, grains, fish and eggs. Drink more water to reduce dry eyes is also helpful.
6.For people over 40 years old, it is better to use bifocal lenses or wear glasses with a lower prescription when typing.
7, avoid long time continuous operation of the computer, pay attention to the intermediate rest, usually 1 hour of continuous operation, rest 5-10 minutes. When resting, you can look away or do eye exercises.
8, maintain a good working posture. Maintain a most appropriate posture, so that the eyes flat or mildly downward looking at the fluorescent screen, which can make the neck muscles relaxed, and make the eye exposed to the air to reduce the area to a minimum.
9, adjust the distance position of the fluorescent screen. The recommended distance is 50-70 cm, and the fluorescent screen should be slightly lower than the horizontal position of the eye 10-20 cm, a 15-20 degree downward perspective. Because the angle and distance can reduce the need for refraction and reduce the chances of eye fatigue.
10, if you would have less tear secretion, eyes prone to dryness, in front of the computer is not suitable for the use of contact lenses, to wear frame glasses. People who wear contact lenses in front of the computer, it is also best to use varieties with a high degree of oxygen permeability.
11, if there is redness in the eyes, a burning or foreign body sensation, heavy eyelids, blurred vision, or even eye swelling or headache, and still no significant improvement after rest, then it is necessary to go to the hospital.
Third, the vitreous turbidity treatment methods
1, Western medicine: the general first for the cause of anti-inflammatory or hemostatic treatment, followed by the application of iodine preparations, hyaluronidase, urokinase or calcium agents to promote absorption: the use of ultrashort wave, or ultrasound and sodium iodide iontophoresis and other physical therapy.
2, Chinese medicine: according to the patient’s physique, symptoms and local conditions, Chinese medicine for flexible identification and use of drugs to treat vitreous turbidity, has been generally recognized by the medical community.
3, combined Chinese and Western medicine treatment: Chinese medicine and Western medicine treatment combined with modern treatment means. Can reduce the adverse reactions caused by the use of Western medicine, compared with the use of Western medicine alone, can shorten the course of treatment, improve the efficacy, so the combination of Chinese and Western medicine treatment, vitreous turbidity has a wide range of prospects.
4, surgical treatment: vitrectomy, can successfully cure such cases. Removal of the vitreous helps restore vision. And can do intraoperative, for the cause of the retinal photocoagulation and other treatments. Many vitreous turbidities are seen in young patients and, moreover, the posterior vitreous membrane is mostly adherent to the retina, which needs to be removed intraoperatively, but it is very difficult to separate the adhesions. The postoperative inflammatory response usually requires, systemic immunosuppressive therapy. Optic nerve atrophy or retinal damage, especially macular cystoid edema, is the main cause of limited postoperative visual recovery. Therefore, simple degenerative vitreous lesions, resulting in vitreous opacities, need to be operated with caution. Severe vitreous turbidity can only be considered for surgical treatment if conservative treatment is ineffective, which is generally not recommended.
The vitreous turbidity treatment methods above several treatment methods, patients must be careful to choose.
