Purpose To evaluate the concentrations of brimonidine and timolol in the vitreous and aqueous humors after instillation of a 0.1% brimonidine tartrate and 0.5% timolol fixed-combination ophthalmic solution. Methods This single-arm open-label interventional study included patients with macular holes or idiopathic epiretinal membranes who were scheduled for vitrectomy. Written informed consent was obtained from all participants. A 0.1% brimonidine tartrate and 0.5% timolol fixed-combination ophthalmic solution was administered topically twice daily for 1 week preoperatively. The vitreous and aqu

Abstract:
ABSTRACTEight eyes of 7 patients with fungal disease received intravenous injections of 150 to 300 mg micafungin, and samples of blood, cornea, retina-choroid, aqueous humor, and vitreous humor were collected. The micafungin levels in all collected samples exceeded the MICs; however, the levels in the vitreous and aqueous humors were lower. Our findings suggest that intravenous micafungin should be given in combination with intravitreal antifungal agents after vitrectomy in severe cases of intraocular fungal diseases.

ABSTRACTThe aim of this study was to determine the penetration of doripenem administered intravenously into the rabbit aqueous and vitreous humors. Nineteen New Zealand White rabbits received a 20-mg dose of doripenem intravenously over 60 min. Specimens of aqueous humor, vitreous humor, and blood were obtained 30 min (n= 5), 1 h (n= 5), 2 h (n= 5), and 3 h (n= 4) after the beginning of the infusion and analyzed by high-performance liquid chromatography (HPLC). A pharmacokinetic (PK) model was developed to fit the experimental data. Doripenem concentrations in aqueous humor were lower than tho

Abstract:
By means of 103 medico-legal autopsies it was established that a rise in the creatine level occurs in the vitreous humour after death. In view of the satisfactory correlation between the post-mortem interval and the creatine level in the vitreous humour (r = 0.84, p < 0.001) investigations were undertaken as to whether the creatine level in vitreous humour can serve in current medico-legal practice as an indication for the post-mortem interval, especially for the later period (more than three days). On balance this creatine determination is only useful when combined with all other medico-le

Extracts of normal vitreous have been found to inhibit angiogenesis in two animal models: tumour-induced neovascularization in the rabbit corneal micropocket and retinal extract-induced angiogenesis in the chick chorioallantoic membrane assay. Using in vitro assays, we have found recently that an extract of bovine vitreous, free of hyaluronic acid, inhibits proliferation of cells in the aortic wall, i.e. endothelium and smooth muscle cells, as well as capillary and corneal endothelium. The inhibition is dose-dependent, as determined by either cell count or [3H]thymidine incorporation, and not

Abstract:
The vitreous humour is the substance that fills the posterior chamber. The vitreous body ensures the adherence of the retina to the underlying layers and acts as a barrier for heat and drug transport between the anterior and the posterior segments of the eye. In the medical literature many authors have postulated the existence of a connection between the fluid dynamics within the vitreous chamber during eye movements (especially when the substance filling the chamber is a liquid) and the occurrence of the retinal detachment. In the present PhD Thesis the vitreous humour dynamics is studied by

Abstract:
In this work, the dynamics of vitreous humour (VH) and of a range of pharmacological fluids used to replace VH in eye surgery were investigated, both experimentally and numerically. Vitreous humour is a gel-like viscoelastic material that fills the majority of the ocular globe. Age-related changes occur in the VH, and as a consequence VH becomes progressively liquefied with age, which has an impact on the corresponding rheological properties, and leads to the appearance of vitreoretinal pathologies. The most effective treatment for such diseases is the injection of a VH substitute in the vitre

Ele pode ser uma ferramenta para determinação de drogas de abuso, sobretudo quando é impossível fazer a determinação em sangue devido à sua ausência ou sua deterioração, por exemplo em casos de exsanguinação, embalsamento e carbonização. As drogas e seus metabólitos passam para o HV por difusão passiva e, de modo geral, a concentração dos analitos no HV é similar às concentrações obtidas no sangue.

The vitreous cavity constitutes most of the eye volume and is filled by the vitreous humour or vitreous body. It has the shape of a weakly deformed sphere, the deformation being essentially due to the presence of the lens, which produces an inward indentation in the anterior part of the chamber. Under normal conditions the vitreous body has the consistency of a gel with viscoelastic rheological behaviour [1].
