Personally, I have no experience in Glaucoma and Cataract.
You might go to the Doctor Thyroid Forum and ask Dr. Lupo at
http://www.medhelp.org/forums/show/120 OR
at left of page almost top, under "Thyroid Disorders" in red click on "thyroid" it will take you to the forum.
OR
Go to the Medical and Health list of Doctor-to-Patient or Patient to Patient Forums at:
http://www.medhelp.org/forums.htm and chose a forum that fits your condition and/or needs.
If you have posted more than one post per the sites rules for doctors forums, you probably won't get answered. Or if the forum is full and not taking any more questions for the day, you can try another day.
Good luck and Best of health!
