Eye Diseases

Being aware of the symptoms and early warning signs of eye diseases can assist in early detection, prevent vision loss and slow the progression of the disease. 

That’s why regular eye examinations with your local ProVision optometrist are so vital, so that even the slightest changes in your eye health can be detected. If vision loss has already occurred, treatment can avert further deterioration. Don't be blind to the risks, have your eyes tested today.

Glaucoma

Glaucoma is a disease that affects the optic nerve, preventing the flow of information from the eye to the brain resulting in permanent vision loss. It primarily affects people over the age of 40. People with Glaucoma may be unaware of any problems until vision loss has become severe, which is why regular eye examinations and Glaucoma testing before the age of 40 are essential.

TREATMENT
Early detection and treatment are essential in saving a patient’s vision. While there is no cure for Glaucoma, treatments are available to slow down any further damage. Depending on how far the glaucoma has progressed, a range of treatments are available including:

  • Eye drops (most common form of treatment)
  • Laser treatment (often used in conjunction with eye drops)
  • Surgery to create a new channel in the eye allowing proper drainage of fluid

Ask your local ProVision optometrist for more information on glaucoma, or visit the Glaucoma Australia website.

Macular Degeneration

Macular Degeneration is a disease that affects the macula, the central part of the retina located at the back of the eye. The macula is responsible for our central vision and allows us to read, recognise faces, drive and see colours clearly. When the macula is impaired, people experience blurriness or dark spots in their central vision forcing them to rely on peripheral vision to identify objects by shape.

RISK FACTORS & TREATMENT
The cause of Macular Degeneration is not clear however risk factors include UV exposure, aging and lifestyle factors such as smoking and poor diet. As with Glaucoma, early detection is key to slowing the progression of the disease as vision loss caused by Macular Degeneration is irreversible. Regular eye examinations are therefore vital.

SYMPTOMS

  • Difficulty reading which cannot be corrected with glasses
  • Difficulty identifying colours
  • Straight lines appear distorted or bent
  • Words or letters merging together when reading
  • Central vision appears blurred or blocked by dark empty spaces

Cataracts

Cataracts are a cloudiness that forms in the lens of the eye, causing poor vision as the cloudiness interferes with light entering the eye. Most cataracts are age related, which means the chances of developing them later in life are higher. If left untreated cataracts can cause blindness. People with cataracts may experience difficulty reading, recognising faces and watching television.

TREATMENT
For many people, cataracts won't require surgery. Cataracts may become a nuisance but often they develop to a certain level and then stabilise. If they begin to interfere with everyday activities, the cataract affected lens can be surgically removed and replaced with a clear artificial lens.

Your ProVision optometrist can provide you with professional advice about cataracts and refer you to a specialist for treatment.

Diabetic Retinopathy

People with diabetes are more at risk of developing eye conditions such as cataracts and glaucoma, and most significantly, Diabetic Retinopathy. This occurs when diabetes causes damage to the fine blood vessels in the retina. If left undetected and untreated, Diabetic Retinopathy can cause serious eye damage including blurred vision and even blindness.

SYMPTOMS
Often there are no early warning signs of diabetic retinopathy however symptoms can include blurry, fluctuating or double vision, focusing problems, dry eyes, difficulty seeing at night and an overt sensitivity to glare.

TREATMENT & MANAGING YOUR RISK
At present there is no cure for diabetic retinopathy, but early detection and optimal management can prevent up to 98% of vision loss.^ The good news is that while the risk of developing retinopathy is present, maintaining your blood sugar levels within the recommended range, adopting a healthy lifestyle and having your eyes tested regularly can reduce your risk by up to 58%.^

Be sure to have your eyes tested at least every 2 years or as recommended by your local ProVision Optometrist.

Floaters

Floaters are a build-up of protein cells, seen as tadpole-like substances floating around in front of your eyes. They will not be seen when looking at dark surfaces such as dark carpets or walls as they are only seen if there is sufficient contrast.

Floaters moving continuously in one direction are usually harmless; however floaters that are motionless can be indicators of an eye problem or disease and should be further investigated by your local ProVision Optometrist
