The vitreous body bulges into the anterior chamber through the pupil
Introduction
Introduction Protrusion of the vitreous through the pupil to the anterior chamber is one of the clinical symptoms of vitreous hernia. Common in cataract extraction after cataract extraction. When the vitreous hemorrhoids contact with the corneal endothelium, it is easy to cause corneal edema and turbidity.
Cause
Cause
Vitreous hernia refers to the vitreous bulging through the pupil to the front chamber. Common in cataract extraction after cataract extraction. When the vitreous hemorrhoids contact with the corneal endothelium, it is easy to cause corneal edema and turbidity.
Most of the vitreous hemorrhoids are formed due to cataract extraction after cataract extraction. Glaucoma can be secondary to obstructing aqueous circulation. Vitreous fistula after cataract extraction from the cataract. The anterior interface is pigmented and the pupil is partially blocked.

Therefore, clinically, patients with vitreous bulging through the pupil of the pupil should be examined:
First, physical examination
Taking a medical history gives us a first impression and revelation, and also guides us to a concept of the nature of the disease.
Second, laboratory inspection
Laboratory examinations must be summarized and analyzed based on objective data learned from medical history and physical examination, from which several diagnostic possibilities may be proposed, and further consideration should be given to those examinations to confirm the diagnosis. Such as: ophthalmoscopy.
Diagnosis
Differential diagnosis
Visible cysts in the vitreous: patients with vitreous porcine cysticercosis, the vitreous is turbid to varying degrees, translucent light gray or light blue spherical capsules are visible in the vitreous, and the center often has a grayish white or yellowish white circular spot. The head of the cystic sac is sometimes seen to squirm in the vitreous. Early feelings have oval black shadows fluttering and telescopic deformation, creeping shadows. In the late stage, visual acuity can be significantly reduced due to interference and inflammation in the tissues of the eye. Even blind.
Non-vitreous lesions in front of the fly: Congenital physiological floaters are a type of physiological floater. When a normal person looks at a white object or a blue sky, it can be found that there are small dots or filament floats floating in front of the eyes, sometimes closed eyes can be seen, but objective examination can not find any vitreous lesions. It is a physiological floater. It is generally thought that it is caused by the projection of cells of the vitreous cortex or blood cells walking in the blood vessels of the retina on the retina.
There is blood in the vitreous: it is a common complication of visual trauma caused by ocular trauma or retinal vascular disease. On the one hand, bleeding not only makes the refractive medium turbid, hinders the light from reaching the retina, but also can cause serious damage to the eye tissue; On the one hand, the body's response to bleeding can gradually clear the blood. In different cases, the consequences of vitreous hemorrhage are very different, according to the primary injury, the amount of bleeding in the off-duty, the absorption of bleeding and the performance of the eye reaction, etc., timely appropriate clinical treatment.
