of the clinical worsening of retinal vascular occlusion;
(44)      for retinal arterial occlusion only:
(a)          having carotid artery disease at the time of the clinical worsening 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 worsening of retinal vascular occlusion;
                Note: Examples of a cardiac disease with the potential to give rise to a retinal embolus include:
                   (a)             acute myocardial infarction;
                   (b)            atrial fibrillation; and
                   (c)             mitral or aortic valve disease.
(c)          having a non-cardiac potential source of retinal embolus at the time of the clinical worsening of retinal vascular occlusion; or
               Note: Examples of a non-cardiac potential source of retinal embolus include:
                   (a)             aortic arch atherosclerosis;
                   (b)            atherosclerotic central retinal artery;
                   (c)             decompression sickness;
                   (d)            deep vein thrombosis in the presence of a potential route of paradoxical embolism;
                   (e)             pulmonary barotrauma; and
                   (f)             severe bone trauma.
(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 worsening of retinal vascular occlusion;
             Note 1: Examples of a procedure to the heart include:
                    (a)             cardiac surgery or cardiac catheterisation;
                    (b)            coronary angiography; and
                    (c)             coronary artery bypass grafting.
             Note 2: Examples of a procedure to the carotid artery include:
                    (a)             carotid angioplasty;
                    (b)            carotid endarterectomy; and
                    (c)             carotid stenting.
                Note 3: Examples of an intravascular procedure involving the vessels of the head or neck include:
                    (a)             cosmetic vein sclerotherapy to the orbital adnexa, face, nose or sinuses;
                    (b)            transcatheter thyroid artery embolisation; and
                    (c)             transfemoral cerebral angiography.
(45)      inability to obtain appropriate clinical management for retinal vascular occlusion.
