Glaucoma Cataracts Diabetes
Peter D’Arcy OPTOMETRIST BEGA monitors such conditions utilising where necessary Canon OCT (optical coherence tomography) to aid in evaluation ensuring maximum vision is preserved and corrected. The latest Canon OCT allows for high resolution evaluation of eye anatomy eg high definition cross sectional and three dimensional images to determine the extent of complications.
The prevalence of diabetes is climbing rapidly and can result in a number of serious complications including diabetic eye disease.
We can monitor Visual fields by Medmont computerised perimetry and assess vision and referral including cataracts.
Glaucoma is the leading cause of irreversible blindness worldwide.Half of people with this condition in Australia are undiagnosed.
There may be no warning symptoms.
More than 95% is undiagnosed in developing countries.
Early detection and adherence to treatment are vital to slow progression.
While anyone may develop glaucoma, if you have a first degree relative with glaucoma you have a 1 in 4 chance of developing glaucoma as well.
Glaucoma is a complex disease. Family history is vital and genetic testing is being developed as over 100 genes cause glaucoma.
Over 40 per cent of people have a first degree relative (parent, brother or sister) affected by glaucoma.
Many systemic and ocular conditions can be associated.
Glaucoma Australia promotes the risk awareness campaign for developing glaucoma to encourage regular eye testing.
Glaucoma is the leading cause of avoidable blindness in Australia, affecting over 300,000 Australians.
While nine out of 10 Australians say that sight is their most valued sense, over 8 million Australians are still not having regular eye tests though recommended.
Ideal glaucoma treatments include eye drops:
Cataracts are a leading cause of blindness and treatment of cataracts is the most common eye surgery performed.
Common causes that can increase the risk,signs and symptoms include:
Referral can be recommended for cataract surgery at the appropriate time for cataract removal.
Cataracts are very common in the long term with advancing age but can be present at birth or later as a result of metabolic conditions, medications, exposure to radiation,electric shock, trauma, and ocular or systemic diseases.
Such clouding of all or part of the lens may effect sight differently in bright light or dim light as the pupil will be a different size.
Congenital cataracts not withstanding a cataract is a clouding of the transparent tissue behind the iris that occurs in so called age related cataract.
Types of cataracts are graded by density and location during eye examinations during the early stages to ensure the risk of cataracts and other eye conditions does not degrade vision.
A nuclear cataract forms deep in the central zone (nucleus) of the lens. Nuclear cataracts usually are associated with aging.
A subcapsular cataract occurs at the back of the lens often associated with diabetes or steroid medications
The cortical cataracts are spoke like cataracts that tend to develop from the periphery of the lens towards the center.
Laser light from the red end of the visible spectrum (close to infra-red) is bounced back in different directions and manifests as an ultra accurate map of the anatomical structures.
The Canon OCT has 3 μm optical axial resolution 70,000 A scan/second allowing for accurate 10 layer segmentation,comparison and progression. It is non invasive and non contact.
