Ocular Prosthesis and Children

Losing an eye or having to have an ocular prosthesis fitted due to a diseased eye is traumatic for anyone but for children it can be ten times worse.  The not knowing what is happening to them can be especially frightening and then added to this, is also seeing the trauma of the parents whilst all this is happening to them.  The only way to lessen this trauma in both cases is to have as much knowledge at hand as you can on the why's and wherefore's of the treatment and processes involved in receiving a prosthetic  eye.  Children need to see the confidence of their parents so they can feel their own confidence  and be secure  in the knowledge that everything is  going to be fine.

Sight Trauma Relief

Being afflicted with a visual impairment due to disease or accident can make your life seem quite futile and hopeless but there is help out there for you if you require it.

The Gauteng Provincial Government, Department of Health and Social Development have initiated a Rehabilitation Service for those who need to find some help in what seems a difficult situation.

How to make an Ocular Prosthesis?
An Ocular Prosthesis (artificial eye) can be made from either an acrylic, or a silicate glass.

Silicate glass cannot be polished or modified.  The manufacture of an ocular prosthesis could take up to 5 appointments depending on the appointment times and the travelling to and from the practise.

The first stage of the production process is to make an impression of the socket by placing an impression paste into the orbit and this is made up into a plastic shell that is temporarily inserted into the socket specifically for this process.  This is a painless procedure.

The model of the impression is then shaped to fit the orbit successfully.

The colour of the iris is hand painted to match the natural eye colour, as too with painting the veins. This is then cooked as part of the ocular prosthesis.

Artificial Eye Maintenance

Losing an eye is an emotive event in one's life.  When you have been through the trauma of the surgery and then had an artificial eye inserted, you must then know how to take care of it or this in its self will cause you more problems and more unnecessary stress.

You must make up your mind to see your ocularist regularly; twice a year at least, this will stop any major problems from coming to a head and keep you feeling comfortable with the new eye.  A prosthetic eye can last up to 5 years with good maintenance discipline.

Retinal Degeneration and Scleral Shells

Retinal degeneration is the breakdown of the rods and cones in the retina.  This can happen through a myriad of disorders.  Rod cells pick up movement out to the corner of your eye and work in poor light or at night. Cones give you the ability to see colour and do close precision work as in reading.  Rods and cones are situated in the retina and rods are more numerous being 120 million situated towards the outer edge of the retina. Cone cells are not as many and more concentrated in the centre of the retina

Degeneration of the retina can be inherited.  Recessive degeneration being the most common. This is carried by both parents and gives any child a 25% chance of inheriting the disease. The dominant form of retinal pigmentosa is another form of degeneration and can strike all family members.
