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.
Some of the many causes of hypoxia are the following: 1  Chemical or gas poisoning (for example cyanide, carbon monoxide) 2  Low or absent concentration of oxygen (for example, high altitudes reached without supplemental oxygen as seen in mountain climbing, and aviation, drowning or fires)  Lung problems, for example:
