vitreous opacity
Introduction
Introduction to vitreous opacity The normal vitreous is a transparent gel, which itself has no blood vessels and nerve tissue. Its metabolism is extremely slow, and its nutrition and metabolism are completed by the spread of adjacent tissues. Vitreous opacity means that the vitreous body is dusty, filamentous, flocculent, strip-like, and cloud-like turbid. It is not an independent eye disease, but one of the common clinical signs of ophthalmology, which can be caused by a variety of diseases. Common causes include: vitreous degeneration of the elderly, retinal or uveal bleeding into the vitreous, high myopia, embryonic cells or tissues that are congenitally left in the vitreous, ocular trauma, intraocular foreign bodies, parasites and tumors. Physiological people do not need treatment, and pathological patients should be treated for the cause of the disease. Generally, the first cause is anti-inflammatory or hemostasis treatment, followed by iodine preparation, hyaluronidase, urokinase or calcium to promote absorption. basic knowledge The proportion of illness: 1% Susceptible people: no specific people Mode of infection: non-infectious Complications: cataract vitreous hemorrhage glaucoma
Cause
Cause of vitreous opacity
Bleeding (35%):
Hemorrhage caused by retinal phlebitis, venous obstruction, diabetes, hypertension, trauma or surgery enters the vitreous, forming a red, yellow, grayish-white flaky or lumpy turbidity during blood entry and absorption.
Trauma (35%):
Uveitis and the like cause pigment particles to enter the vitreous body, parasites and their metabolites, intraocular tumors or tumors in other parts of the body to metastasize, causing turbidity. In the ocular trauma, foreign bodies in the vitreous body remain, and the fibrous tissue in the vitreous tissue is caused by eye trauma, bleeding, and diabetes.
Vitreous degeneration (20%):
More common in the elderly and high myopia, vitreous hyaluronic acid depolymerization liquefaction, diabetes and hypercholesterolemia in the vitreous can be cholesterol crystal body.
Prevention
Vitreous opacity prevention
Early diagnosis, early treatment, prevention of inflammation, bleeding and other causes of vitreous opacity, strengthen safety publicity and education, reduce eye trauma.
Proper rest, avoid fatigue, do regular work and rest, use your eyes for 5 to 10 minutes every hour for a long time, don't use your computer for too long, and you will have a better time when you feel unwell. In addition, you can take appropriate eye care products, and you can eat more foods containing vitamin C, such as vegetables and fruits.
Complication
Vitreous opacity complications Complications, cataract, vitreous hemorrhage, glaucoma
Vitrectomy sometimes causes some complications, so the complications caused by the operation should be prevented. If it occurs, it should be treated in time. The common complications of vitrectomy include the following, such as corneal edema, cataract, vitreous incarceration. Vitreous hemorrhage, glaucoma, retinal tears or retinal detachment.
Symptom
Symptoms of vitreous opacity Common symptoms The visual acuity of the eye shadow in front of the eye is often foggy
Disease symptoms
1. The shadows in front of the eyes flutter and flutter with the movement of the eyeballs;
2. Different degrees of vision loss. Disease hazards may have traction retinal detachment due to different causes.
Examine
Vitreous opacity check
With the direct ophthalmoscope +6 ~ +8D check, when the eyeball rotation stops suddenly, the black fluttering small dots or clumps can be seen under the red light reflection background of the fundus. Under the indirect ophthalmoscope, the floating of various different properties can be clearly distinguished. Under the slit lamp and the three-sided mirror, the source and nature of the turbidity can be judged in more detail.
Diagnosis
Diagnosis of vitreous opacity
1. 90D microscopy under ophthalmoscope or slit lamp can be seen, the turbidity of different forms such as dust, strip, mesh or floc in the vitreous body flutters with the movement of the eyeball;
2. If the turbidity is serious, the fundus may not be visible or there is no red reflection.
3. Type B ultrasonic examination can assist in diagnosis.
