The fluorescein angiogram would likely show areas of capillary non-perfusion as well as vessel staining and leakage. Purtscher's retinopathy is a retinal vasso-occlusive angiopathy, the exact mechanism of which is not clear. Some theories suggest that fat, air, or even leukocyte emboli result in the blockage of the preterminal retinal arterioles. It is known that complement activation and complement induced leukocyte aggregation occur conditions as diverse as trauma, pancreatitis, and connective tissue diseases. The treatment is observation and supportive care.
Visual outcome depends upon the severity and location of the nerve fiber infarcts.
