Eye Tests and Examinations in George in South Africa
The new digital retinal camera at Weldon Optical in George (South Africa) gives a photo with a high definition view of a large area of the retina and optic nerve head. During eye tests and examinations in the past the interior of the eye was inspected with a hand-held instrument called an ophthalmoscope. This produced a highly magnified view of small areas of the retina. Because of pupil size and the high magnification early abnormalities and small changes over time can be very difficult to spot and can easily be overlooked.
The digital retinal camera now used by the Optometrists at Weldon Optical in George (South Africa) offers the following amazing benefits:
- So much more detail is visible.
- The image can be recalled and compared with future findings as a means of detecting slow-changing conditions much earlier.
- The image can be ‘zoomed’ for even closer inspection, and manipulated in various ways to show details that cannot be seen by using any other method. It also allows the optometrist to study the retina as a whole rather than in several smaller views.
- “Second opinions” can be given by any of our four Optometrists.
- More accurate referrals can be made to the Ophthalmologists.
- Why is it recommended?
Many conditions that affect the eye can only be detected by examining the retina. It therefore makes sense to use the best method of inspection and comparison. Our new retinal camera records, in accurate detail, the appearance of the internal structures of the eyes. Because changes that happen in conditions like diabetic retinopathy or glaucoma occur very subtly, the abnormalities are difficult to detect without having something to compare the appearance against. This ability to store and recall such high quality images is a major step forward. Although there are obviously differences, the closest analogy to this advancement would be the use of x-rays in dentistry, or MRI scanning in the modern hospital.
- What is involved?
The process of capturing retinal images usually only takes a few minutes. You will sit at the Retinal camera and be asked to look at a target. After the camera is aligned there is a brief flash to illuminate the inside of your eye. The procedure is then repeated for the other eye. Sometimes more than one image may be required for each eye.
