There is a localized dilatation of the retinal artery (there may be multiple aneurysms) with surrounding 
area of hard exuedate (which may be retinal and/or subretinal). There may be associated 
retinal/subretinal/preretinal/vitreous haemorrhages. The appearance is that of a macroaneurysm.

Look for:

  • exudate in the macula
  • artery occlusion or embolus distal to the site of macroaneurysm
  • hypertensive changes of the retinal vessels
