Causes diabetic retinopathy blindness? The answer is yes, untreated diabetic retinopathy can cause blindness. There are different ways in which this can occur.
In the early stages there are no symptoms, sometimes even at the most advanced ages there are no symptoms. When symptoms do become apparent it is usually to some degree difficulty in reading.
Diabetes affects the large and small blood vessels in the body, and it also directly affects the nerves. In the early stages of diabetic retinopathy, there may be very small dot haemorrhages on the retina surface or focal swellings called microaneurysms.
The YAG laser is a highly specialised laser that is designed specifically for use in the eye and is safe to do so. It delivers light in a very focused manner, and it is essentially a cutting instrument.
The simplest is a YAG laser vitreolysis; this is effective for certain types of floaters where there are certain membranous opacities in your vitreous jelly. The YAG laser focuses very high energy light to a very small area and effectively evaporates or disintegrates these floaters.
The eye is a camera that has a series of lenses at the front and a license to film at the back. And in a camera there would normally be air between the lense and the film but in your eye that airspace is filled by a vitreous jelly.
Initially, they may simply be flashing lights and floaters. These flashing lights develop in the dark when you move your eye. It is often described as the lightning flash or a flicker that last for a view seconds.
In some patients for various reasons this lining starts separating from the eye surface. This process is called retinal detachment. The most common reason this happens is because the jelly structure, that lies immediately in front of the retina, starts collapsing in on itself.
The injections are very well tolerated by the eye. Patients have been injected anything up to 30 times over three years without any complications. That said there are some very rare complications such is a serious infection that can develop that can cause complete loss of vision in the eye
Most people can do almost all normal household activities the same day after an injection for AMD. The vision will be a bit blurred for a few hours and some patients complain of a little black dot which is a tiny air bubble in the eye that they see floating at the bottom.
