Name
This is the Statement of Principles concerning optochiasmatic arachnoiditis (Reasonable Hypothesis) (No. 57 of 2016).
Commencement
This instrument commences on 23 May 2016.
Authority
This instrument is made under subsection 196B(2) of the Veterans’ Entitlements Act 1986.
Application
This instrument applies to a claim to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 applies.
Definitions
The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
Kind of injury, disease or death to which this Statement of Principles relates
(1)This Statement of Principles is about optochiasmatic arachnoiditis and death from optochiasmatic arachnoiditis.
Meaning of optochiasmatic arachnoiditis
(2)For the purposes of this Statement of Principles, optochiasmatic arachnoiditis means chronic inflammation of the arachnoid membrane surrounding the optic chiasm and intracranial optic nerves, resulting in damage to these structures from fibrosis and the formation of adhesions, and typically presenting with progressive visual loss.
Death from optochiasmatic arachnoiditis
(3)For the purposes of this Statement of Principles, optochiasmatic arachnoiditis, in relation to a person, includes death from a terminal event or condition that was contributed to by the person’s optochiasmatic arachnoiditis.
Note: terminal event is defined in the Schedule 1 – Dictionary.
Basis for determining the factors
The Repatriation Medical Authority is of the view that there is sound medical‑scientific evidence that indicates that optochiasmatic arachnoiditis and death from optochiasmatic arachnoiditis can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.
Note: relevant service is defined in the Schedule 1 – Dictionary.
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;
Note: leptomeninges is defined in the Schedule 1 - Dictionary.
(16)having an intrathecal myelogram or intrathecal treatment with a substance from the specified list of substances before the clinical worsening of optochiasmatic arachnoiditis;
Note: specified list of substances is defined in the Schedule 1 - Dictionary.
(17)inability to obtain appropriate clinical management for optochiasmatic arachnoiditis.
Relationship to service
(1)The existence in a person of any factor referred to in section 8, must be related to the relevant service rendered by the person.
(2)The factors set out in subsections 8(9) to 8(17) apply only to material contribution to, or aggravation of, optochiasmatic arachnoiditis where the person’s optochiasmatic arachnoiditis was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
Factors referring to an injury or disease covered by another Statement of Principles
In this Statement of Principles:
(1)if a factor referred to in section 8 applies in relation to a person; and
(2)that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(2) of the VEA;
then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
Schedule 1 - Dictionary
Note: See Section 5
Definitions
In this instrument:
cumulative equivalent dose means the total dose of ionising radiation received by the particular organ or tissue from external exposure, internal exposure or both, apart from normal background radiation exposure in Australia, calculated in accordance with the methodology set out in Guide to calculation of 'cumulative equivalent dose' for the purpose of applying ionising radiation factors contained in Statements of Principles determined under Part XIA of the Veterans' Entitlements Act 1986 (Cth), Australian Radiation Protection and Nuclear Safety Agency, as in force on 2 August 2017.
Note 1: Examples of circumstances that might lead to exposure to ionising radiation include being present during or subsequent to the testing or use of nuclear weapons, undergoing diagnostic or therapeutic medical procedures involving ionising radiation, and being a member of an aircrew, leading to increased levels of exposure to cosmic radiation.
Note 2: For the purpose of dose reconstruction, dose is calculated as an average over the mass of a specific tissue or organ. If a tissue is exposed to multiple sources of ionising radiation, the various dose estimates for each type of radiation must be combined.
leptomeninges means the arachnoid mater and the pia mater, the two innermost layers of the cerebral meninges between which there is circulation of cerebrospinal fluid.
MRCAmeans the Military Rehabilitation and Compensation Act 2004.
optochiasmatic arachnoiditis—see subsection 6(2).
relevant service means:
(a)operational service under the VEA;
(b)peacekeeping service under the VEA;
(c)hazardous service under the VEA;
(d)British nuclear test defence service under the VEA;
(e)warlike service under the MRCA; or
(f)non-warlike service under the MRCA.
specified list of substances means:
(a)iophendylate (Pantopaque or Myodil);
(b)radioactive gold; or
(c)thorium dioxide (Thorotrast).
terminal event means the proximate or ultimate cause of death and includes the following:
(a) pneumonia;
(b) respiratory failure;
(c) cardiac arrest;
(d) circulatory failure; or
(e) cessation of brain function.
VEA means the Veterans' Entitlements Act 1986.
