At least one of the following factors must exist before it can be said that, on the balance of probabilities, retinal vascular occlusion or death from retinal vascular occlusion is connected with the circumstances of a person's relevant service:
(1)          having smoked at least 20 pack-years of tobacco products before the clinical onset of retinal vascular occlusion, and where smoking has permanently ceased, the clinical onset of retinal vascular occlusion has occurred within ten years of cessation;
            Note: one pack-year is defined in the Schedule 1 - Dictionary.
(2)          having hypertension before the clinical onset of retinal vascular occlusion;
(3)          having diabetes mellitus before the clinical onset of retinal vascular occlusion;
(4)          having dyslipidaemia before the clinical onset of retinal vascular occlusion;
            Note: dyslipidaemia is defined in the Schedule 1 - Dictionary.
(5)          having hyperhomocysteinaemia before the clinical onset of retinal vascular occlusion;
(6)          having an arteritis from the specified list of systemic arteritides, at the time of the clinical onset of retinal vascular occlusion;
            Note: specified list of systemic arteritides is defined in the Schedule 1 - Dictionary.
(7)          having retinal vasculitis at the time of the clinical onset of retinal vascular occlusion;
            Note: retinal vasculitis is defined in the Schedule 1 - Dictionary.
(8)          having a non-inflammatory vasculopathy of the cerebral or retinal vessels from the specified list of vasculopathies at the time of the clinical onset of retinal vascular occlusion;
            Note: specified list of vasculopathies is defined in the Schedule 1 - Dictionary.
(9)          having a disorder that is associated with a hypercoagulable state or hyperviscosity at the time of the clinical onset of retinal vascular occlusion;
Note: disorder that is associated with a hypercoagulable state or hyperviscosity is defined in the Schedule 1 - Dictionary.
(10)      having:
(a)          a benign or malignant neoplasm; or
(b)          a non-neoplastic mass lesion;
which compresses or infiltrates the retinal vessels of the affected eye at the time of the clinical onset of retinal vascular occlusion;
             Note 1: Examples of a benign or malignant neoplasm include astrocytoma, optic nerve meningioma, leukaemia and lymphoma.
             Note 2: Examples of a non-neoplastic mass lesion include haematoma, sarcoidosis, neurofibromatosis and exophthalmos.
(11)      having a vascular abnormality of the retinal vessels of the affected eye at the time of the clinical onset of retinal vascular occlusion;
Note: Examples of a vascular abnormality include arterio-venous malformation and prepapillary vascular loop.
(12)      having migraine at the time of the clinical onset of retinal vascular occlusion;
(13)      having infection with human immunodeficiency virus before the clinical onset of retinal vascular occlusion;
(14)      having an ocular or orbital infection involving the affected eye within the 30 days before the clinical onset of retinal vascular occlusion;
            Note 1: Examples of an
