Question re


I saw in a post ksman asked that question to someone when they were discussing their stats.

I think i am losing some peripheral vision in one eye and was planning a trip to the eye dr soon. i'm 42 and also planning a physical in a few weeks and doing my homework to see what kind of blood work to request.

what may the change in peripheral vision mean?


Pituitary tumors, called adinomas are not rare. These can lower LH/FSH thus reducing T, or increasing prolactin, which also lowers LH/FSH as a negative feedback signal on the HPTA. The adinoma can press on one or both optic nerves, which pass right by the pituitary, which can reduce peripheral vision or create other visual field disturbances [not refractive errors]. Any such changes should also be brought to the attention of an eye specialist, in case there is something going on wrong with the eye.

Some vision problems can be a symptom of hypogonadism.
