At Teahan Optometrists we always invest in the latest diagnostic equipment to enhance our patients’ care. We are currently using Optical Coherence Tomography (OCT) as an integral part of the standard eye examination. This is a 3 dimensional imaging technique that images the internal eye structures, including the retina, in great detail.OCT is a non-invasive, painless, diagnostic test.  The OCT takes high resolution digital photographs, and uses light waves to take cross-sectional images 3-D images of the retina. The cornea and irido-corneal angle can also be imaged.

What is myopia? ‘Near-sighted’ or ‘short-sighted’ are more commonly known terms for myopia. A myopic person cannot see clearly in the distance, but they have clear sight up-close.  Currently 28% of the global population are myopic. It is estimated that by 2050, 50% of the global population will be myopic (a staggering 5 billion people!). With this increasing prevalence of myopia worldwide, methods of myopia control are becoming research topics of great interest. Myopia usually starts in childhood and teenage years and generally progresses as the eyes continue to grow.
