Common Eye Conditions


A cataract is what we call the lens in the eye when it goes cloudy. The lens is about the size and shape of a Smartie and sits behind the iris, the coloured part of the eye. The lens helps focus light on the retina, which is the film in the camera in the back of the eye that lets you see.

Age-related Macular Degeneration

Age-related Macular Degeneration (ARMD) is the leading cause of legal blindness in patients over the age of 50, with about 1 in 7 Australians in this age group displaying some signs of the disease. The macula is the very small area at the centre of the retina, which is the film in the camera in the back of the eye that lets you see.

Epiretinal Membrane

An ‘epiretinal membrane’ is a fine sheet of scar tissue on the surface of the retina, not unlike sticky tape. The retina is the light-sensitive part of the eye like the photographic film in a camera. It is very delicate nerve tissue, about one-third of a millimetre thick,

Macular Hole

A ‘full thickness macular hole’ is, as the name suggests, a hole that forms in the centre of the macula. The macula is the central part of the retina -the light-sensitive part of the eye like the photographic film in a camera. The macula serves your fine central vision,

Central Serous Chorioretinopathy (CSCR)

CSCR describes a condition where pockets of fluid collect under the retina (the photographic film in the camera in the back of the eye that lets you see). Accumulation of fluid in this space can disrupt vision and cause blurring in the affected eye.

Retinal Vein Occlusions (CRVO & BRVO)

The retina is the photographic film in the camera in the back of the eye that lets you see. Retinal vein occlusion (RVO) occurs when one of the veins draining blood from the retina becomes blocked. This causes varying degrees of vision loss depending on the location, severityand number of blood vessels involved.

Tears are composed of water, fatty oils and mucus that keep the eye surface smooth and clear, wash away foreign matter, and prevent infection.
