Choroidal blood flow after the first intravitreal ranibizumab injection in neovascular age-related macular degeneration patients.

Purpose: To analyse choroidal blood flow (ChBF) changes after the first intravitreal ranibizumab injection in naïve, age-related macular degeneration (ARMD) patients.

Methods: Subfoveal ChBF was assessed by laser Doppler flowmetry (LDF) in newly diagnosed ARMD patients. Both treated and untreated eyes were assessed in each subject at each visit before the first intravitreal ranibizumab injection as well as 24 hr (day 1) and 7 days after (day 7).

[A comparative cost analysis of single-use versus reusable fiberoptic bronchoscopes: Is single-use fiberscope worth it?].

Objective: To present a minimization-cost analysis to compare reusable and single-use fiberscopes in a French health institution.

Materials And Methods: The amortization cost assessment has been achieved over a period of five years, and took into account the acquisition and maintenance costs, as well as the costs related to disinfection of reusable fiberscopes. The cost of single-use fiberscopes was calculated according to its acquisition and elimination costs.

[Vascular factors in glaucoma].

The exact pathophysiology of glaucoma is not fully understood. Understanding of the vascular pathophysiology of glaucoma requires: knowing the techniques for measuring ocular blood flow and characterizing the topography of vascular disease and the mechanisms involved in this neuropathy. A decreased mean ocular perfusion pressure and a loss of vascular autoregulation are implicated in glaucomatous disease.
