Hi,
Here is retinopathy from my point of view.
I've been T1 for 33 years, since I was 11. About 13 years ago I started suffering the effects of retinopathy. This is where the blood vessels that supply the retina get damaged and new, weak vessels grow to replace the blood supply. As they cannot take the pressure of the blood, they weep or burst causing cloudy or black streaks of blood to leak into the gel of the eye. To stop the leaks and new growth, lasers are used to burn them which stops them from growing. This treatment also causes damage to the retina and small blind spots occur as a result.
Retinopathy does not seem to be linked directly with the time that you have been diabetic. I know of some people who have been unaffected by it over many years and others, like you who suffer within a few years of diagnosis.
In my case the laser treatment started with just a few shots at a time but over a couple of years more and more treatment was needed and eventually the laser shots could not keep up with the amount of bleeding. This led to me having 2 vitrectomies. This is a surgical operation where they cut small holes in the eye, remove the blood and gel, apply many shots of laserto the retina, refill the eye with saline and oil and put tiny stitches in the eye. It sounds bad but there no real pain involved. The result was good and my eyesight has remained stable since the op.
The thing to remember when deciding whether to cut your alcohol intake is that alcohol has a negative effect on the eyesight of heavy drinkers who are not diabetic, so will almost definitely add to the problems of retinopathy (as it thins the blood, allowing it to seep more easily through any damaged blood vessels). I, like you, was diabetic through my teens and I believe that the amount of alcohol I drank on a regular basis, although not hugely excessive, probably had an impact on my current condition, due to poor blood sugar control whilst drinking. So although I've not completely lost my sight (and total blindness is unusual), retinopathy has had a lasting effect on my abilities. I am blind in my left eye now with restricted visual fields and lowered vision in my right eye and I had my driving license revoked about 10 years ago.
I hope that this gives you an idea of how things can possably develop, and helps you decide how to play it.
Regards,
