Vitreous protrusion through the pupil into the anterior chamber is most often seen in the case of vitreous hernia, a protrusion of the vitreous body through the pupil into the anterior chamber. It is commonly seen after intracapsular extraction of cataracts. Vitreous herniation tends to cause corneal edema and clouding when in contact with the corneal endothelium. After intracataract extraction, the vitreous body is embedded from the pupil to the anterior chamber, which is called vitreous hernia. It may cause glaucoma secondary to obstruction of atrial aqueous circulation. Vitreous herniation after intracapsular extraction of cataract. There is pigmentation at the anterior interface and the pupil is partially blocked. So, what are the tests for vitreous protrusion through the pupil to the anterior chamber? 1.Inquire about any history of myopia, trauma, hemorrhage and other eye diseases. 2.Dilated pupil slit lamp and triple-lens examination of the vitreous for liquefaction, posterior detachment, clouding, hemorrhage, proliferation and other changes and retinal lesions. 3.B-type ultrasonography.
