Eye Conditions

You can read brief information about common eye conditions in this section. This is general information for patients and the public and is not a substitute for advice from your ophthalmologist. If you have specific questions or concerns about various eye conditions, please visit your local GP.

BlepharitisInflammation of the margins of the eyelids. It can occur in children and adults of any age.What is Blepharitis?

Cloudy areas on the lens of the eye which develop as a normal part of aging. By the age of 70, nearly everyone has some degree of cataract formation.What are Cataracts?

Charles Bonnet Syndrome (CBS)
An under-recognised condition causing visual hallucinations in people who have lost vision as a result of various eye conditions.What is Charles Bonnet Syndrome?
Detached RetinaWhen a retinal detachment occurs, the retina is separated from the underlying tissue. Wherever the retina detaches, vision is lost and a shadow develops. This can lead to total blindness in the affected eye. In most cases, the cause is a retinal tear or hole.What is a Torn or Detached Retina?
Diabetic RetinopathyIn people with diabetes, tiny blood vessels in the retina may become diseased and damaged. Diabetic Retinopathy usually affects the retina slowly, over months or yearsMDFA - Diabetic Retinopathy

What is Diabetic Retinopathy?
Dry Eye SyndromeThis occurs when the eye does not produce enough tears or the tear quality is poor. In Australia and New Zealand, Dry Eye affects one adult in 10.What is Dry Eye?
Chronic EpiphoraAbnormal and chronic overflow of tears from the eye. The condition can involve surgery and is distinct from acute epiphora, which usually results from an irritant to the eyes, such as sawdust or an allergy.
Floaters and FlashesUsually associated with the aging process and can involve small dark shapes entering the field of vision or small flashes of light. Floaters and flashes are usually just annoying, not harmful. However, the sudden onset of many new floaters or flashes could be a warning of looming serious eye problems, including tears of the retina or a detached retina.What are Floaters and Flashes?
GlaucomaA group of eye diseases that damage the optic nerve that links the retina to the brain. Often, glaucoma is associated with too much pressure inside the eyeball. It is a leading cause of damage to vision or blindness in people over 40 but can affect people of any age. If glaucoma is detected early, treatment can prevent or reduce vision loss in most patients.What Is Glaucoma?
Age-related macular degeneration (AMD)This occurs when the macula, a small area of the retina, is damaged. AMD usually affects both eyes but it may produce symptoms in one eye first. If AMD continues to its late stages, severe visual impairment can result. In most cases, visual loss is in the central part of vision.MDFA - Macular Disease

What Is Macular Degeneration?
PterygiumA wedge-shaped growth of thickened tissue that covers the white part of the eye. It can grow to cover the pupil, become red, irritated, cause astigmatism and become uncomfortable. The tissue may have to be surgically removed.
Refractive SurgeryThis surgery treats nearsightedness (myopia), farsightedness (hyperopia) and/or astigmatism. The aim is to reduce a person's dependence on glasses and contact lenses.What is Refractive Surgery?
Strabismus SurgeryA visual problem in which the eyes are not aligned properly and point in different directions. It may be present all the time or it can come and go. It may occur in one eye only, or it may alternate from eye to eye.What Is Strabismus?

Transient Ischaemic Attacks (TIA)
Warnings of possible serious problems involving the brain’s blood supply, also known as ‘mini strokes’. URGENT investigations and review by a stroke physician are needed.
UveitisInflammation of any part of the uvea, the middle tissue layer of the eye. Sometimes, uveitis affects other areas of the eye, for example, the retina, optic nerve or the lens. Uveitis can be acute (lasting days or weeks) or chronic. Some cases of uveitis can seriously affect vision and the long-term health of the eye.What Is Uveitis?
