AB Papilledema  involves  swelling  of  the  optic  nerve  head,  usually  in  association  with  elevated  intracranial  pressure.  The  optic  disks  are  hyperemic  with  blurred  disk  margins;  the  venules  are  dilated  and  tortuous.  The  optic  cup  may  be  obscured  by  the  swollen  disk.  There  may  be  flame  hemorrhages  and  infarctions  (white,  indistinct  cotton  wool  spots)  in  the  nerve  fiber  layer  and  edema  in  the  surrounding  retina.
