Virtual reality – what is it, and what are the effects of virtual reality on the eyes and the visual system? Some may say virtual reality is the way of the future. Virtual reality is a fairly new technology where you view the virtual world as if you were inside the virtual space, with 360 degree […]
Astigmatism We have been talking about refractive errors this week. Having discussed myopia and hyperopia, we move on to another type of refractive error: Astigmatism. Astigmatism is a term that a lot of people are familiar with, yet are uncertain as to what it actually means. What is Astigmatism and how is it caused? Astigmatism differs from Myopia […]
Hyperopia Today, we continue on with our back to basics series, discussing refractive errors. To recap, a refractive error means that the eye does not bend or refract light properly to see images clearly or in focus. Having discussed myopia yesterday, or ‘short sightedness’, today we take a look at Hyperopia which is also known as ‘far sightedness’ and ‘long […]
Myopia We are looking at refractive errors this week as we continue on with our back to basics series for 2017. As discussed yesterday in our refraction overview, a refractive error means that the eye does not bend or refract light properly to see images clearly or in focus. Today we are looking at Myopia, […]
Refraction of the Eye and Refractive Errors What is Refraction? Refraction is a term used in optical physics and describes “the bending of light rays at the interface between two different transparent media”. It is the phenomenon which makes image formation possible by the eye as well as by cameras and other systems of lenses. Light […]

It is important to understand that eye turning in children (paediatric strabismus) is never normal, except in the first three months of life. […]
Is treatment available for adult strabismus? Yes, treatment options are available for adult strabismus, and these treatments have a high success rate. Adult strabismus is a complex field of ophthalmology, where the cause of the strabismus and the type of strabismus dictate the treatments that will be successful. Often surgery is recommended, and sometimes eye […]
What is Strabismus? Strabismus is the medical term for misalignment of the eyes, a wandering eye, and what is often called a squint, lazy eye, cross eyed, or wall eyed. It occurs when the eyes do not align when looking at an object. Strabismus has many causes, classifications and types, and can occur in both […]
Back to Basics – Retinal Disorders Retinal Vascular Disorders What are Retinal Vascular Disorders? Retinal vascular disorders refers to a range of eye diseases that affect the blood vessels in the eye. These conditions are linked back to pre-existing vascular diseases such as hypertension (high blood pressue) and arthrosclerosis (thickening of the artery walls). The most common […]
Retinal Disorders Retinal Detachment We have been looking at the retina this week as part of our back to basics series. As discussed, the retina is the light-sensitive layer of tissue that lines the inside of our eye and sends visual messages through the optic nerve to our brains. When discussing retinal detachments, it is necessary to […]
Retinal Disorders Diabetic Retinopathy Continuing with our look at common eye conditions, one that must be discussed is Diabetic Retinopathy. What is Diabetes? Before we investigate Diabetic Retinopathy we should first look at Diabetes itself. Diabetes is a group of conditions in which there is too much glucose in the blood. Glucose is the main […]
Retinal Disorders Macular Degeneration This week we are looking at the Retina & some of the conditions which affect the function of the retina. Today the focus is on Macular degeneration. What is Macular Degeneration? Macular Degeneration is also referred to as Age Related Macular Degeneration or AMD as it generally affects people as they age. There is a […]
Overview of the anatomy of the Retina The retina is a thin layer of light-sensitive tissue at the back of the eye that covers about 65 percent of its interior surface. It is made up of ten layers as illustrated in the diagram below: What does the Retina do? The purpose of the retina is […]
To round off our back to basics section on cataracts, below are some details about our cataract surgeons at Sydney Ophthalmic Specialists and where they operate in Sydney.
