iklpixi,
There's no point in me telling you not to worry, cause worry you will. I know this from experience, about 10 years back I had a routine eye check at diabetes clinic, and they found I had diabetic retinopathy. Over the years, until 18 months back I have had laser treatment on both eyes, lost count how many times, but mainly in my left, and 5 years back I had a severe bleed in my left eye. After waiting 6 months to see if the hemorrhage cleared, as it didn't I had a 4 hour vitrectomy operation to remove the vitreous jelly from my eye. After 3 months I developed a cataract in this eye and had small op to replace the lens of my eye. I had a small showing in my right eye again 18 months back, had laser and thankfully things have settled down since.
Now, I know why I developed retinopathy in my eyes, in my early years of diabetes I would often have hba1c's of around 10, and I believe that due to my neglect of my condition, the retinopathy was the price I paid. Despite quite intensive laser treatment and vitrectomy operation, I still have good vision, I wear glasses for driving (short sighted) but can read well and watch tv with no problems. My consultant is amazed that my eyes have recovered so well despite the work that has been done on them.
Therefore, having some experience of diabetic retinopathy, I can tell you what I know and have been told about preventing and limiting further damage. As the others have said, it is paramount that you keep good control of your diabetes, and aim for a hba1c of below 7 if possible. Do this gradually, as a sudden drop can result in unstabilizing the blood vessels in the eyes. Blood pressure, I know that you stated it is fine, but mine was too, but my consultant at the eye clinic thinks that blood pressure control is just as important as good glucose control in diabetics, therefore he wrote to my gp and suggested that I take a small dose of meds to lower bp, as he thinks the lower the bp, the less pressure on the eyes and other vital organs. So, for the last few years I take 10mg of ramipril, but like Kegstore, take a vit c tablet and take a supplement called Bilberry plus, which I have read is beneficial to eye health (google for more info). And last but not least cholesterol, again the lower the better, below 4 is ideal.
As I said, you'll worry just the same, but as you have only developed diabetic retinopathy, it is only in the early stage, and the fact that you have accepted that you need to tighten things up, it has been a wake up call, following the good advice from other members, hopefully it could mean you may never have to experience this again, who knows its all in your hands. Below I have posted a link to a excellent site that is dedicated to the subject of diabetic retinopathy, anything you want to know you will find on this site.
