Visual Field Testing
Your visual field is the area that you can see at any one time – whilst looking at a fixed object, it is the extent of your peripheral vision in all directions around the object. When testing your visual field, the sensitivity of your eyes at a range of points is compared to the results of an average person your age.
If your results show reduced peripheral vision you will usually be referred for specialist investigation as this could be an indication of a number of different conditions, for example glaucoma – a condition our optician Ian has undergone extensive additional training in.
Slit-lamp Microscopy
This test involves a special microscope which allows a magnified view of the eyelids and front section of the eye. It is particularly useful and commonly used in the fitting of contact lenses, removal of suspected foreign bodies in the eye and evaluation of the causes of dry eyes. It can also be used in combination with a tonometer or an additional volk lens to allow assessment of the retina. At Ralph Carr optician our optician Ian has undergone full additional training programmes for both tonometer and volk lens techniques.
Fundus Photography
Also known as retinal photography, Fundus cameras allow digital photographs to be taken of the retina. These photographs can be compared to your previous retinal images for accurate monitoring of the progression of eye conditions such as diabetes, glaucoma and macular degeneration.
Low Vision Aids
Whilst glasses, contact lenses or surgery can correct many visual defects, there are some occasions where more powerful visual aids are necessary. These are particularly common requirements for people who are blind or partially sighted.
Low Vision Aids can encompass a range of options depending on your individual circumstances. These include computerised magnifiers, which make the text up to 70 times larger and contrast filters which make text easier to see. We can carry out assessments to determine the most suitable aid for you and talk you through your options if necessary. There are many simple changes which can be made that keep a visually impaired person independent in their own home. We can offer advice and information about local services.
Ian our optician at Ralph Carr has close links with local Low vision Aid services following the additional training he has had with them.
