Your service
I have identified that you have the following service:
Australian Defence Force service between :
22 January 1996 and 30 June 2016
Right Eye - Pterygium
You have stated that your condition was caused by:
- having sunlight exposure to the eye which is not protected by clothing, ultraviolet-blocking sunglasses, or other physical barrier, for a cumulative period of at least 2,250 latitude equivalent hours before clinical onset
- having exposure of the affected eye to electric arc welding light, while welding without appropriate eye protection, such as a welding helmet or welding mask, for an average of at least 20 hours per week, for at least the 2 years before clinical onset
- having heavy exposure of the unprotected eye to sawdust, in an environment where the person is covered in sawdust, for an average of at least 20 hours per week, for at least the one year before clinical onset
Diagnosis: Pterygium
Basis of diagnosis: The diagnosis was made in the Diagnostic Assessment by Dr Thomas Perkins dated 9 April 2025, and is supported by a specialist consultation by the ophthalmologist, dated 18 November 2008.
I am satisfied this is the appropriate diagnosis.
In determining your claim for this condition, I have applied the SOP:
Statement of Principles concerning Pterygium (Reasonable Hypothesis) (No. 33 of 2025)
which sets out the factors that can connect the condition with service.
I am satisfied that you have met the following factor:
- having sunlight exposure to the eye which is not protected by clothing, ultraviolet-blocking sunglasses, or other physical barrier, for a cumulative period of at least 2,250 latitude equivalent hours before clinical onset
- having exposure of the affected eye to electric arc welding light, while welding without appropriate eye protection, such as a welding helmet or welding mask, for an average of at least 20 hours per week, for at least the 2 years before clinical onset
- having heavy exposure of the unprotected eye to sawdust, in an environment where the person is covered in sawdust, for an average of at least 20 hours per week, for at least the one year before clinical onset
I have noted your contention as to the cause of this condition. The available evidence indicates, I have noted your contention to the cause of your condition. Your service medical records indicate that you presented to the health facility with a visible fleshy growth on the inner aspect of the right eye with redness, a gritty foreign body sensation, watering in wind and sun, and intermittent irritation worse after welding and dusty work on 2 September 2008.
The diagnosis was confirmed by an ophthalmologist on slit lamp examination on 18 November 2008, which showed a triangular fibrovascular lesion in the nasal interpalpebral fissure of the right eye, extending 1.5 mm onto the cornea, firmly united to the cornea at its apex, adherent to the sclera through its middle portion and merging with the conjunctiva at its base. It was not a pseudo-pterygium (there was no history of corneal ulceration or chemical injury and a probe could not be passed beneath it) and was distinct from the pinguecula in the left eye. This meets the Statement of Principles definition of pterygium.
This has then led to further investigations and the diagnosis of your condition of Pterygium. I have accepted your condition of Pterygium.
Having considered your service records and the available medical evidence, I am satisfied the SOP is met and that this condition is related to your wartime service.
I have therefore accepted that this condition is related to your service with effect from 20 August 2008.

Your service
I have identified that you have the following service:
Australian Defence Force service between :
22 January 1996 and 30 June 2016
Right Eye - Pterygium (Worsening)
You have stated that the worsening of your condition was caused by:
- inability to obtain appropriate clinical management for pterygium before clinical worsening
Diagnosis: Pterygium (Worsening)
Basis of diagnosis: The diagnosis was made in the Diagnostic Assessment by Dr Thomas Perkins dated 9 April 2025, and is supported by a specialist consultation by the ophthalmologist, dated 18 November 2008.
I am satisfied this is the appropriate diagnosis.
In determining your claim for this condition, I have applied the SOP:

It was not a pseudo-pterygium (there was no history of corneal ulceration or chemical injury and a probe could not be passed beneath it) and was distinct from the pinguecula in the left eye. This meets the Statement of Principles definition of pterygium.
After the condition arose, it was worsened during your service. Excision of the pterygium was recommended on 14 August 2012, but you were deployed on warlike service in Afghanistan from 12 October 2012 to 28 June 2013, where no ophthalmic surgery was available.
This has then led to further investigations and the diagnosis of your condition of Pterygium (Worsening). I have accepted your condition of Pterygium (Worsening).
Having considered your service records and the available medical evidence, I am satisfied the SOP is met and that the worsening of this condition is related to your wartime service.
I have therefore accepted that the worsening of this condition is related to your service with effect from 5 May 2013.
