1 Name This is the Statement of Principles concerning open-angle glaucoma (Balance of Probabilities) (No. 50 of 2021). 2 Commencement This instrument commences on 24 May 2021. 3 Authority This instrument is made under subsection 196B(3) of the Veterans' Entitlements Act 1986. 4 Repeal The Statement of Principles concerning open-angle glaucoma No. 28 of 2012 (Federal Register of Legislation No. F2012L00459) made under subsections 196B(3) and (8) of the VEA is repealed. 5 Application This instrument applies to a claim to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 applies. 6 Definitions The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument. 7 Kind of injury, disease or death to which this Statement of Principles relates (1) This Statement of Principles is about open-angle glaucoma and death from open-angle glaucoma. Meaning of open-angle glaucoma (2) For the purposes of this Statement of Principles, open-angle glaucoma: (a) means an acquired, progressive optic neuropathy involving characteristic optic disc abnormalities and associated visual field defects, occurring in the presence of an open iridocorneal angle and usually associated with raised intraocular pressure; and (b) includes normal tension glaucoma; and (c) excludes congenital, infantile or development glaucomas. Note 1: Open-angle glaucoma may be primary, or secondary to another eye disorder. Note 2: Open-angle glaucoma may be asymptomatic until the optic nerve damage is severe. (3) While open-angle glaucoma attracts ICD‑10‑AM code H40.1, in applying this Statement of Principles the meaning of open-angle glaucoma is that given in subsection (2). (4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4. Death from open-angle glaucoma (5) For the purposes of this Statement of Principles, open-angle glaucoma, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's open-angle glaucoma. Note: terminal event is defined in the Schedule 1 - Dictionary. 8 Basis for determining the factors On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that open-angle glaucoma and death from open-angle glaucoma can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA. Note: MRCA, relevant service and VEA are defined in the Schedule 1 - Dictionary. 9 Factors that must exist At least one of the following factors must exist before it can be said that, on the balance of probabilities, open-angle glaucoma or death from open-angle glaucoma is connected with the circumstances of a person's relevant service: (1) having glucocorticoid therapy as specified, before the clinical onset of open-angle glaucoma, and where the glucocorticoid therapy as specified has ceased, the last dose of the therapy was received within the three months before the clinical onset of open-angle glaucoma; Note: glucocorticoid therapy as specified is defined in the Schedule 1 - Dictionary. (2) having uveitis, scleritis or episcleritis at the time of the clinical onset of open-angle glaucoma; Note: uveitis, scleritis and episcleritis are defined in the Schedule 1 - Dictionary. (3) having: (a) a benign or malignant neoplasm; or (b) a non-neoplastic lesion; of the affected eye at the time of the clinical onset of open-angle glaucoma; Note 1: Examples of a benign or malignant neoplasm include lymphoma, trabecular meshwork melanoma, choroidal metastasis and retinoblastoma. Note 2: Examples of a non-neoplastic lesion include cyst, ocular haemorrhage (including ghost cells), leakage of lens protein or lens particles and vascular malformation or thrombosis. (4) having growth of new blood vessels (neovascularisation) of the iridocorneal angle due to a condition or procedure involving the affected eye from the specified list of conditions or procedures, before the clinical onset of open-angle glaucoma; Note: specified list of conditions or procedures is defined in the Schedule 1 - Dictionary. (5) having trauma to the affected eye before the clinical onset of open-angle glaucoma; Note: trauma is defined in the Schedule 1 - Dictionary. (6) having sympathetic ophthalmia at the time of the clinical onset of open-angle glaucoma; Note: sympathetic ophthalmia is defined in the Schedule 1 - Dictionary. (7) having intraocular surgery to the affected eye before the clinical onset of open-angle glaucoma; (8) undergoing a course of therapeutic radiation for cancer, where the affected eye was in the field of radiation, before the clinical onset of open-angle glaucoma; (9) having: (a) eye disease associated with Graves' disease; or (b) hypothyroidism within the 12 months before the clinical onset of open-angle glaucoma; (10) having glucocorticoid therapy as specified, before the clinical worsening of open-angle glaucoma, and where the glucocorticoid therapy as specified has ceased, the last dose of the therapy was received within the three months before the clinical worsening of open-angle glaucoma; Note: glucocorticoid therapy as specified is defined in the Schedule 1 - Dictionary. (11) having uveitis, scleritis or episcleritis at the time of the clinical worsening of open-angle glaucoma; Note: uveitis, scleritis and episcleritis are defined in the Schedule 1 - Dictionary. (12) having: (a) a benign or malignant neoplasm; or (b) a non-neoplastic lesion; of the affected eye at the time of the clinical worsening of open-angle glaucoma; Note 1: Examples of a benign or malignant neoplasm include lymphoma, trabecular meshwork melanoma, choroidal metastasis and retinoblastoma. Note 2: Examples of a non-neoplastic lesion include cyst, ocular haemorrhage (including ghost cells), leakage of lens protein or lens particles and vascular malformation or thrombosis. (13) having growth of new blood vessels (neovascularisation) of the iridocorneal angle due to a condition or procedure involving the affected eye from the specified list of conditions or procedures, before the clinical worsening of open-angle glaucoma; Note: specified list of conditions or procedures is defined in the Schedule 1 - Dictionary. (14) having trauma to the affected eye before the clinical worsening of open-angle glaucoma; Note: trauma is defined in the Schedule 1 - Dictionary. (15) having sympathetic ophthalmia at the time of the clinical worsening of open-angle glaucoma; Note: sympathetic ophthalmia is defined in the Schedule 1 - Dictionary. (16) having intraocular surgery to the affected eye before the clinical worsening of open-angle glaucoma; (17) undergoing a course of therapeutic radiation for cancer, where the affected eye was in the field of radiation, before the clinical worsening of open-angle glaucoma; (18) having: (a) eye disease associated with Graves' disease; or (b) hypothyroidism within the 12 months before the clinical worsening of open-angle glaucoma; (19) inability to obtain appropriate clinical management for open-angle glaucoma. 10 Relationship to service (1) The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person. (2) The factors set out in subsections 9(10) to 9(19) apply only to material contribution to, or aggravation of, open-angle glaucoma where the person's open-angle glaucoma was suffered or contracted before or during (but did not arise out of) the person's relevant service. 11 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 9 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(3) 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.
