I've always been a bit of a wimp when it comes to eyes. I can't bear them to be touched - never have, way before I had my TT in 1982. I tend to avoid posts that might be 'a little close to home ' because even a story about eye damage can make me flinch and turn away. However, you've only got the two, and one of mine's got a pterygium. This may or may not be related to decades of T4 only, although I suspect it IS, as I can't see how 30 years of T4 can entirely replace 30 years of the real thing ( Don't get me wrong - I'd've been dead years ago without the thyroidectomy)
BUT if I'd had T3 as an option/addition - or an Endo - GP only for 20 years - things may have been better. Anyway, back to the pterygium. I've tried viscotears, hypromellose and just rubbing 'Don't keep rubbing your eyes, dear!' and so far just rubbing has proved to be by far the best. So there. Once you have no Thyroid tissue at all, you're open to many or all of the odd conditions around - thyroid orbitopathy, anyone? - unless you can maintain a euthyroid state through medication (pause for hollow laughter) . My magnificent GP has bunged me another load of T3 as he agrees that my Endo is a diabetes specialist waiting to see what happens next.
