True or false: elevated TT4 count is extremely specific for hyperthyroidism?
Hypertension associated with hyperthyroidism, if severe, may cause these ocular complications?
In treating hyperthyroidism, we often can unmask this condition by reducing hypertension, and therefore GFR...
Hence it is usually recommended to start with a therapeutic agent that is not curative, to check if this shows up. 
This drug, when given to hyperthyroid patients, inhibits T3 and T4 production without destroying thyroid tissue.
This is considered the safest, simplest, and most effective treatment for hyperthyroidism. It kills hyperplastic cells.
