I was kind of lucky in the sense the vision loss was at the very bottom of my eye and not central. I'm still a bit pee' d off about it really as to why screening was cancelled so much due to the pandemic. Well, according to my optician, it seemed to be a complete lottery - some people got it, others not.. Apparently, I wasn't a priority when I called the hospital.
I also can't believe everything came to a stand still, I had covid, no vaccine and it was more mild than a common cold - they only thing I had was that fact, for some odd reason, I couldn't sleep for the duration, and I lost sense of smell and taste. Given covid, or my eye sight, it's a no brainer. Then of course there were people who were diabetic and lost their lives due to not even being seen. Seemed everything was put aside for one reason - covid. Anyway, thats a whole other topic.
Given the fact that things are back to normal now (well kind of), and you should get your treatment in good time (if needed), you should be fine. Also, just keep an eye on your BG, eat healthy, exercise and keep an eye on blood pressure and cholesterol. It may also be worth investing in some supplements like Lutein, Vitamin A, Omega 3, Complete B vitamins, and some others with a focus on promoting eye health. Last thing, try not to worry about it, I know it's easier said than done, but it will just drive you mad.
