Weird situation with my optometrist

So, im entirely unsure what to do and I don’t want to go against the requirement of disclosing information.

I have finished my medical, right now im dealing with a medically unfit letter for ONLY my medication nothing mentioned about my vision, around a month after getting that letter my optometrist gave me a appointment for a specialist optometrist. And during that appointment they told me I have thick corneas but I am a “glaucoma suspect”. They want to have a second appointment at the end of December to confirm if I have it or not

So my main question is, do I have to tell the caf when I hand in my medical appeal? This might sound like an obvious answer but it’s technically not an official diagnosis, more of a speculation

I want my file to be moved on as soon as possible and having it be paused all the way until my appointment in December will be a huge hit of waiting. But I also don’t want to break any rules or get denied for withholding information. If I have to wait then I will but if I don’t have to tell them until a result that would be better

Please someone let me know what I should do
