Letrozole/ Femara and eyesight

Hi all am now 4months into Letrozole and seem to be having some vision impacts - dialled up old faithful doctor google and there’s a lot or articles about the impact of Hormone Therapy on vision including some concerns re AIs. Is anyone else having any eye issues. I had glaucoma prior to breast cancer controlled by drops but now am needing laser treatment as my eye pressure is elevating.I have also noted dry eye esp when inserting drops. Saw the eye specialist Monday but will be seeing him again soon due to his concerns about my eye pressure and will be asking questions about what I have read.I gather eye impacts of Tamoxifen is well known but AIs less so.

    I've only been on letrozole for a week but haven't noticed any eye issues as yet though I'm probably due for an eye test. My two biggest things are increased joint pain and tiredness.

    I have been on Femara for four and a half years and have had no problems with pressure or glaucoma (had a scan recently and definitely fine on the glaucoma front). I do need treatment for cataracts but I am satisfied that is age related (my mother had treatment for same at roughly the same age) and not letrozole related. But your eye specialist is the go to person rather than Dr Google. A good specialist can glean the fact from the possible opinion and should be able to answer your questions. Good luck for your next consultation, hope it's all resolved.

    I feel my eyesight is a little different since chemo but I have waited for testing as wanted to give my body a chance for full cell recovery following chemo.

    Glaucoma is a progressive disease for many people and this may have happened regardless of treatment . We often do blame medication /treatment for things that may have just happened as part of ageing, normal disease processes.  Drs are often reluctant to say no its not anything to do with that just in case it is,  even though they might have mentally dismissed it. 

    I hope your treatment works well. Kath x

    I am to have laser treatment early December and now have an additional eye drop daily. I have dry eyes now and the Ganfort drops I have had for years sting a little. My eye specialist is aware there is some evidence of eye impacts from ARomatase inhibitors and will monitor- me I will continue the  Letrozole just wish sideeffects esp longer term were clearer as would be less worrying if it was known what to expect .Thankyou ladies once again for your kind support .
