8               Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting optochiasmatic arachnoiditis or death from optochiasmatic arachnoiditis with the circumstances of a person's relevant service:
(1)          having a bacterial, fungal or parasitic infection involving the leptomeninges surrounding the optic chiasm or intracranial optic nerves before the clinical onset of optochiasmatic arachnoiditis;
Note: leptomeninges is defined in the Schedule 1 - Dictionary.
(2)          having a subarachnoid haemorrhage or bleeding into the subarachnoid space before the clinical onset of optochiasmatic arachnoiditis;
(3)          having surgery to an area in close proximity to the optic chiasm before the clinical onset of optochiasmatic arachnoiditis;
(4)          having a moderate to severe traumatic brain injury before the clinical onset of optochiasmatic arachnoiditis;
(5)          undergoing a course of therapeutic radiation for cancer, where the optic chiasm was in the field of radiation, before the clinical onset of optochiasmatic arachnoiditis;
(6)          having received a cumulative equivalent dose of at least ten sieverts of ionising radiation to the region of the optic chiasm before the clinical onset of optochiasmatic arachnoiditis;
Note: cumulative equivalent dose is defined in the Schedule 1 - Dictionary.
(7)          having sarcoidosis or multiple sclerosis, involving inflammation of the leptomeninges surrounding the optic chiasm, before the clinical onset of optochiasmatic arachnoiditis;
Note: leptomeninges is defined in the Schedule 1 - Dictionary.
(8)          having an intrathecal myelogram or intrathecal treatment with a substance from the specified list of substances before the clinical onset of optochiasmatic arachnoiditis;
Note: specified list of substances is defined in the Schedule 1 - Dictionary.
(9)          having a bacterial, fungal or parasitic infection involving the leptomeninges surrounding the optic chiasm or intracranial optic nerves before the clinical worsening of optochiasmatic arachnoiditis;
Note: leptomeninges is defined in the Schedule 1 - Dictionary.
(10)      having a subarachnoid haemorrhage or bleeding into the subarachnoid space before the clinical worsening of optochiasmatic arachnoiditis;
(11)      having surgery to an area in close proximity to the optic chiasm before the clinical worsening of optochiasmatic arachnoiditis;
(12)      having a moderate to severe traumatic brain injury before the clinical worsening of optochiasmatic arachnoiditis;
(13)      undergoing a course of therapeutic radiation for cancer, where the optic chiasm was in the field of radiation, before the clinical worsening of optochiasmatic arachnoiditis;
(14)      having received a cumulative equivalent dose of at least ten sieverts of ionising radiation to the region of the optic chiasm before the clinical worsening of optochiasmatic arachnoiditis;
Note: cumulative equivalent dose is defined in the Schedule 1 - Dictionary.
(15)      having sarcoidosis or multiple sclerosis, involving inflammation of the leptomeninges surrounding the optic chiasm, before the clinical worsening of optochiasmatic arachnoiditis;
