Refer to Design Step 1 for introductory information about this design example. Additional information is presented about the design assumptions, methodology, and criteria for the entire bridge, including the steel girder. Figure 3-1 Span Configuration. Figure 3-2 Superstructure Cross Section.
HYPOFLUORESCENCE Hypofluorescence may be caused by 1) blocked fluorescence, which is synonymous with negative fluorescence or transmission decrease, or 2) a vascular filling defect. Blocked fluorescence corresponds to the size, shape, and location of the blocking material seen ophthalmoscopically.
Secondary retinal detachment - also known as exudative retinal detachment or serous retinal detachment. It is caused by inflammation, vascular abnormalities or injury which cause fluid to build up under the retina (there is no hole, break or tear). Tractional retinal detachment - an injury, inflammation or neovascularization causes the fibrovascular tissue to pull the sensory retina from the retinal pigment epithelium.
