Brief Answer:
Headache could be related to other causes.
Detailed Answer:
Hi,
Thank you for getting back.
I remember your father's case.
In his case, the headaches are not related to the pituitary macroadenoma. Other factors are responsible. As you mentioned, it could be excessive strain on normal eye and excess use of XXXXXXX phone. In some cases, it could even be tension headache or migraine. As of now, he needs to sleep well and minimise the XXXXXXX phone use.
Best wishes,
