Hello, Welcome to Just Answer

Is your retinal surgeon aware of the new symptoms of bulging of the eye, which increases on bending down?
I have told him about the bulging, but I have only recently noticed that it increases with head down positioning
How was the diagnosis of a pituitary adenoma made- CT scan/MRI scan? Were visual fields tested by perimetry?
it was diagnosed approx 30 yrs ago--have had both CT and MRI over the years, but nothing in past 10 yrs or so--have had regular visual fields done--no problem with those--I have very limited vision Rt eye secondary to the ret detach
Any noticable bulge in an eye is called proptosis. First this has to be differentiated from pseudo-proptosis which canbe seen in case of high myopia/ shallow orbits.Though it is normal for very mild bulging of eyes on bending forward or on holding the breath , it is significant if it is obvious or more visible.
it is quite noticeable at times--not necessarily when I experience pain
Since you have had raised intraocular pressure(IOP) in the right eye, along with a scleral buckle, these could be attributed to the present signs. But apart from this probablity, thyroid profile has to be checked as it is one of the commonest causes for proptosis ( thogu bilateral it can begin in one eye initially).
would the thyroid issue be best followed up through my GP?-I see the surgeon agin in May
You can discuss with your surgeon about the thyroid profile test and ultrasound of the eye ( it is a safe and non-invasive test) which can contribute to form a diagnosis. Yes, your GP should be able to help you with the thyroid test.
can a buckle slip?
Not so common since it is sutured firmly to the sclera.
plan to follow-up with GP office for investigation and with surgeon for scheduled visit in May--will also have pressure checked again at optometry office.
