Retinal Detachment

What is retinal detachment? Retinal detachment occurs when the vitreous jelly pulls away from the retina and the retina moves. This can be a medical emergency so early detection is crucial. What does the retina do and where is it? Very simply, the retina is a light-sensitive area at the back of the eye. It senses light and sends signals to the brain so you can see. The vitreous is the clear gel that fills the space between the lens and the retina. There is a place where that vitreous is tightly stuck to the retina and as we age,

Keeping An Eye On Age-related Macular Degeneration

What is ARMD? Age-related macular degeneration is a leading cause of vision loss for people over 50, making it an extremely common eye condition.

The retina is a thin layer of tissue that lines the back of the inside of the eye, near the optic nerve. The optic nerve connects the eye to the brain. The retina turns light into electrical signals and then sends these electrical signals through the optic nerve, where the brain

Itchy eyes – again?

Hay fever horrors Rising sea levels, horrendous storms: climate change is hammering the world – yeah right. You can believe it or not, but one thing that about 20% of the New Zealand population can attest to is that the increase in temperatures means longer growing seasons, and higher pollen counts for allergy-causing plants, such as trees, grass, outdoor moulds and weeds. Hay fever brings with it red, watery, itchy eyes. Pollen power Climate change could contribute to longer – and harsher – hay fever seasons. Pollen season, which typically runs from late winter until the end of summer, is

Eye protection in winter

The not-so glaringly obvious risks of winter. Winter eye protection is just as important as it is in the summer.  In the gloominess of winter, many of us put away our sunglasses until the longer, sunnier days of summer come back. The overcast skies and lack of sunshine fool us into thinking that our eyes do not need to be shielded from invisible UV rays. But eye protection in winter is very important, sometimes even more so than in summer. UV (or ultraviolet) rays don’t take a break in the winter. In fact, the lower angle of winter sun in
