Statement of Principles

concerning

OPEN-ANGLE GLAUCOMA

ICD-10-AM CODES: 300.01, 300.21H40.1, H40.3-H40.8, H42

Veterans’ Entitlements Act 1986

1. The Repatriation Medical Authority under subsection 196B(3) of the Veterans’ Entitlements Act 1986 (the Act):

(a) revokes Instrument No.14 of 1999; and

(b) determines in its place the following Statement of Principles.

Kind of injury, disease or death

2. (a) This Statement of Principles is about open-angle glaucoma and death from open-angle glaucoma.

(b) For the purposes of this Statement of Principles, “open-angle glaucoma”, means glaucoma associated with an open iridocorneal angle, and includes both primary and secondary forms, attracting ICD-10-AM code H40.1, H 40.3-H40.8 or H42.  This definition excludes congenital glaucomas.

Basis for determining the factors

3. 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.

Factors that must be related to service

4. Subject to clause 6, at least one of the factors set out in clause 5 must be related to any relevant service rendered by the person.

Factors

5. The factors that 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 are:

(a) suffering from exfoliation syndrome involving the affected eye at the time of the clinical onset of open-angle glaucoma; or

(b) suffering from iridocorneal endothelial syndrome involving the affected eye at the time of the clinical onset of open-angle glaucoma; or

(c) suffering from uveitis of the affected eye before the clinical onset of open-angle glaucoma; or

(d)              suffering significant trauma to the affected eye before the clinical onset of open-angle glaucoma; or

(e)              undergoing a course of therapeutic radiation to the region of the affected eye before the clinical onset of open-angle glaucoma; or

(f)               having undergone penetrating keratoplasty or other intraocular surgery of the affected eye before the clinical onset of open-angle glaucoma; or

(g)             undergoing corticosteroid therapy as specified where such therapy or part of such therapy has been received within the 12 months before the clinical onset of open-angle glaucoma; or

(h) suffering from endogenous hypercortisolism within the 12 months before the clinical onset of open-angle glaucoma; or

(j)                suffering from a neoplasm which is either invading or shedding cells into the anterior chamber of the affected eye at the time of the clinical onset of open-angle glaucoma; or

(k)             suffering from Graves’ disease at the time of the clinical onset of open-angle glaucoma; or

(m)           suffering from hypothyroidism at the time of the clinical onset of open-angle glaucoma; or

(n)             suffering from ipsilateral elevated episcleral venous pressure at the time of the clinical onset of open-angle glaucoma; or

(o)             suffering from rhegmatogenous retinal detachment of the affected eye at the time of the clinical onset of open-angle glaucoma; or

(p) for neovascular glaucoma only, suffering from a condition which may give rise to neovascularisation of the iridocorneal angle of the affected eye before the clinical onset of open-angle glaucoma; or

(q) for phacolytic glaucoma only, suffering from cataract of the affected eye at the time of the clinical onset of open-angle glaucoma; or

(r)               for ghost cell glaucoma only, suffering vitreal haemorrhage, hyphema or intraocular surgery involving the affected eye before the clinical onset of open-angle glaucoma; or

(s) for pigmentary glaucoma only, suffering from pigment dispersion syndrome involving the affected eye before the clinical onset of open-angle glaucoma; or

(t)                inability to obtain appropriate clinical management for open-angle glaucoma.

Factors that apply only to material contribution or aggravation

6. Paragraph 5(t) applies 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 not arising out of) the person’s relevant service; paragraph 8(1)(e), 9(1)(e) or 70(5)(d) of the Act refers.

Inclusion of Statements of Principles

7. In this Statement of Principles if a relevant factor applies and that factor includes an injury or disease in respect of which there is a Statement of Principles then the factors in that last mentioned Statement of Principles apply in accordance with the terms of that Statement of Principles.

Other definitions

8. For the purposes of this Statement of Principles:

“a condition which may give rise to neovascularisation of the iridocorneal angle” means one of the conditions set out below:
