             Note: chronic renal failure is defined in the Schedule 1 - Dictionary.

(22)      for retinal arterial occlusion only:
(a)          having carotid artery disease at the time of the clinical onset of retinal vascular occlusion;
(b)          having a cardiac disease with the potential to give rise to a retinal embolus at the time of the clinical onset of retinal vascular occlusion;
                Note: Examples of a cardiac disease with the potential to give rise to a retinal embolus include:

(d)          undergoing a procedure to the heart or the carotid artery, or an intravascular procedure involving the vessels of the head or neck, within the seven days before the clinical onset of retinal vascular occlusion;
             Note 1: Examples of a procedure to the heart include:
                    (a)             cardiac surgery or cardiac catheterisation;
