BLEPHARITIS

BLEPHARITIS

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

CATARACTS

PDF

CATARACT

Cataracts are cloudy areas on the lens of the eye. Vision becomes increasingly poor as light passing through the cataract is decreased and scattered. Early symptoms include glare and sensitivity to bright light. Later, as the cataract continues to worsen, haloes may appear around lights. Vision often becomes blurred, hazy and foggy.

CHARLES BONNET SYNDROME

RANZCO POSITION STATEMENT ON CHARLES BONNET SYNDROME

Charles Bonnet syndrome (CBS) is an under-recognised condition affecting people who have lost vision as a result of various eye conditions such as Age-Related Macular Degeneration (AMD), glaucoma, and diabetic retinopathy. CBS is characterized by vivid, elaborate and recurrent visual hallucinations in psychologically normal people. It most often occurs in older, visually impaired persons.

DETACHED RETINA

PDF

DETACHED RETINA

When a retinal detachment occurs, the retina is separated from the underlying tissue and stops functioning. 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.

DIABETIC RETINOPATHY

PDF

DIABETIC RETINOPATHY 

In people with diabetes, tiny blood vessels in the retina may become diseased and damaged. This process is called diabetic retinopathy. It usually affects the retina slowly, over months or years.

DRY EYE SYNDROME

PDF

DRY EYE 

In Australia and New Zealand, about one adult in 10 is affected with dry eye syndrome. This occurs when the eye does not produce enough tears or the tear quality is poor.

CHRONIC EPIPHORA

PDF

EPIPHORA

Chronic epiphora is an abnormal and chronic overflow of tears from the eye. The condition can involve surgery and is distinct from acute epiphora, which is usually results from an irritant to the eyes, such as sawdust or an allergy.

FLOATERS AND FLASHES

PDF

FLOATERS AND FLASHES

Floaters and flashes are usually 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.

GLAUCOMA

PDF

GLAUCOMA

Glaucoma is the name given to a 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.

AGE-RELATED MACULAR DEGENERATION

MACULAR DEGENERATION

Macular degeneration (MD) occurs when the macula, a small area of the retina, is damaged. MD usually affects both eyes but it may produce symptoms in one eye first. If MD continues to its late stages, severe visual impairment can result. In most cases, visual loss is in the central part of vision.

PTERYGIUM

PDF

PTERYGIUM

A pterygium is a 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 pterygium may have to be surgically removed.

REFRACTIVE SURGERY

PDF

REFRACTIVE SURGERY 

The aim of refractive surgery is to reduce a person's dependence on glasses and contact lenses. This is achieved by treating nearsightedness (myopia), farsightedness (hyperopia) and/or astigmatism.

STRABISMUS

PDF

STRABISMUS SURGERY

Strabismus is the term for incorrect alignment of the eyes; they do not point in the same direction when looking at an object. Strabismus 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.

Transient ischaemic attacks

PDF

TRANSIENT ISCHAEMIC ATTACKS (PDF 1.2MB)

Transient Ischaemic Attacks [TIA] are warnings of possible serious problems involving the brain’s blood supply, and are also known as ‘mini strokes’. Therefore, URGENT investigations and review by a stroke physician are needed. Please see patient information leaflet.
 

UVEITIS AND IRITIS

PDF

UVEITIS AND IRITIS

Uveitis is an inflammation 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.
