PURPOSE To report the incidence of posterior vitreous detachment (PVD) after uneventful state-of-the-art small-incision phacoemulsification with implantation of a posterior chamber intraocular lens (PC IOL). SETTING Department of Ophthalmology, Ludwigshafen Hospital, Ludwigshafen, Germany. METHODS This prospective study evaluated the vitreous status of eyes by biomicroscopic examination, in...

Asteroid hyalosis is an age related vitreous degeneration of unknown etiology, usually described to be unilateral. It's characterized by aggregation of calcium soaps in vitreous body. This benign condition has been reported to be frequently associated to many systemic disorders including diabetes mellitus, systemic arterial hypertension, atherosclerotic vascular disease, hypercholesterolemia an...

The content and distribution of complex carbohydrates of the posterior vitreoretinal juncture of the mouse eye were examined by electron microscopy. Eyes were fixed 24 hr or 192 hr in glutaraldehyde or glutaraldehyde and cetylpyridinium chloride (CPC) and then block-stained with cationic dyes. Globular material of intermediate electron density was found in the basement membrane of the retina an...

Previous experiments have shown that embryonic chick lenses cultured either without their vitreous bodies or with their vitreous bodies in the presence ofouabain alter their intracellular concentrations of sodium and potassium, change their ratio of synthesis of 8-crystallin polypeptides, and develop opacities in cortical or epithelial regions, respectively. In the present investigation b-cryst...

We investigated the spatial variation of vitreous oxygen consumption in enucleated porcine eyes. A custom made oxygen source was fabricated that could be localized to either the mid or posterior vitreous cavity and steady state vitreous oxygen tension was measured as a function of distance from the source using a commercially available probe. The reaction rate constant of ascorbate oxidation wa...

OBJECTIVE To determine whether patients with acute posterior vitreous detachment with pigmented vitreous granules or hemorrhage have a higher likelihood of retinal tear compared with those with qualitatively normal vitreous examination findings. METHODS A multicenter cross-sectional study was performed in 3 peripheral ophthalmic clinics. Patients with acute posterior vitreous detachment were ...
