Sydney Eye Hospital and the Cancer Council NSW are encouraging Australians
to protect their eyes in the winter months in the wake of newly released
Cancer Council NSW research showing that exposure to solar radiation is a
cause of eye cancer.
Damage to the eyes as a result of sun exposure includes; eye melanomas
(eye cancer), cancer of the conjunctiva (the membrane covering the white
part of the eye), skin cancer of the lids and pterygium (an overgrowth of
the conjunctiva on the cornea).
Dr Michael Giblin, ophthalmic surgeon at Sydney Eye Hospital deals with
serious eye conditions due to sun exposure everyday and is appealing to
those with risk factors to take care in the sun. “There are a number of
risk factors associated with eye cancers such as people with a history of
melanoma in the family (any melanoma anywhere on the body), light eye
colour, light skin colour, sun sensitivity, cumulative lifetime ocular
exposure to the sun, previous eye burn, length of time spent outdoors as a
child and teenager and people with a mole on their eye,” said Dr Giblin.
“About 300 Australians are diagnosed with eye cancer and conjunctival
cancers each year. Over 40 Sydneysiders will be diagnosed with eye cancers
this year alone.” Dr Giblin said.
“People with a mole on their eye and those with a history of eye melanomas
should have yearly eye check ups with an ophthalmologist and people over
40 should have an eye check up every two years,” said Dr Giblin.
Dr Andrew Penman, Chief Executive Officer of The Cancer Council NSW
encourages people of all ages to cover up all year round, especially the
under 20s. “We have evidence that tells us sun exposure in the first 20
years of life increases your chances of eye cancer. Winter days can be
just as dangerous as summer days in the sun.”
“We encourage people who are in the sun to wear approved UV-absorbing
close fitting sunglasses and a wide brimmed hat. By doing this you are
blocking out 95 per cent of UV rays,” said Dr Penman.
Prevention is better than cure in the eyes of specialists. “Early
detection and treatment provides better outcomes for patients with eye
melanomas but prevention is even better. If we can get more people
protecting their eyes all year round and not just in the summer we’ll be
saving people’s sight,” said Dr Giblin.
“People need to get to know their eyes and identify when things are
changing with their vision such as blurred or distorted vision or flashing
lights appearing in their line of vision. If any of these changes occur,
acting quickly by seeing your GP for a referral to an ophthalmologist is
imperative,” said Dr Giblin.
Former Director of the National Gallery of Australia and world-renowned
historian, art critic and writer, Betty Churcher was diagnosed with eye
melanoma in October 2003. Mrs Churcher noticed a persistent spot of
flicking light in her right eye throughout the day and bright flashes of
parallel light in her line of vision when in the dark. “It was like a cat
scratching though black velvet. I ignored the changes in my vision for at
least a couple of weeks and thought it was result of me doing a lot of
photocopying with the lid up,” said Mrs Churcher.
It wasn’t until Mrs Churcher was driving that she realised the problem
with her eye sight was more serious. “I was driving and I thought my
glasses had clouded over. I pulled over to clear them and then noticed it
wasn’t the glasses that were cloudy it was my eye.”
“If you notice a difference in your vision don’t just assume it will go
away in time, go and see an ophthalmologist immediately,” said Mrs
Churcher.

Eye Cancer Fact Sheet
Solar Radiation is a cause of ocular melanoma.
Sun exposure in the first 20 years of life increases your chances of eye
cancer.
Over 290 000 Australians have been exposed to UV radiation in the past
year due to solarium use. A solarium can emit UV radiation that is five
times as strong as the midday summer sun. The highest users of solariums
are females aged 25 – 44 years.
Damage to the eyes from sun exposure includes:
-
Eye melanomas (eye cancer)
-
Cancer of the conjunctiva (the membrane covering the white part of the
eye)
-
Skin cancer of the lids
-
Pterygium (an overgrowth of the conjunctiva on the cornea).
Eye Cancer risk factors include:
-
People with a history of melanoma in the family (anywhere on the body)
-
Light eye colour
-
Light skin colour
-
Sun sensitivity
-
Cumulative lifetime ocular exposure to the sun
-
Previous eye burns
-
Length of time spent outdoors as a child and teenager
-
Mole on the eye
Incidence
Over 539 Australians were newly diagnosed with ocular melanoma from 1996
- 1998.
The incidence of ocular melanoma in Australia was higher in men than in
women, especially in people aged 65 years and older and higher in rural
than in urban areas, but was relatively uniform across the Australian
states, particularly in men, and showed little evidence of a trend with
latitude.
People diagnosed with ocular melanoma are more likely to have spent time
outdoors doing activities such as gardening, sunbathing and to have used
sun lamps.
The age incidence curves of ocular melanoma generally reach a peak in
the 80s in both sexes, while rates in men diverge upwards from those in
women after about 55 years of age. The increasing incidence throughout
life would suggest continuing exposure to be a relevant factor, especially
in men. Although epidemiologic observations suggest that sun exposure has
its greatest effect early in life, they do not exclude the possibility of
an effect later in life.
People born in Southern Europe had only one-half and people born in Asia
only one-fifth the rate of ocular melanoma of people born in Australia and
New Zealand.
Prevention
Cover yours eyes with approved UV-absorbing close fitting sunglasses when
in the sun and wear a wide brimmed hat. Both of these measures in
co-operation will block out 95 per cent of UV rays.
Warning Signs
What do I do if I think I have warning signs?
If you experience any changes to your eyes, act quickly by seeing your GP
for a referral to an ophthalmologist for a full eye check.
Who should have an eye check up by an ophthalmologist?
People who experience distorted or cloudy vision or notice flickering of
light in their line of vision should have an eye check up by an
ophthalmologist immediately.
Yearly check ups with an ophthalmologist
People with a mole on their eye or a history of eye melanomas.
Check up every two years
People over 40 years
