Injection would be short lived and does no good. No real way to bring the eye back as it's throwing in the towel. Some prosthetics have anchors and do move normally (but have additional risk of infection and exposure). Others can have some movement. All options should be discussed with a competent orbital surgeon.
Thankyou. Do modern prosthetic eyes move with the muscles etc? I thought maybe an injection to boost the pressure maybe possible???
Sounds like the eye is going through the steps of phtisis bulbi. The eye will likely shrink and look deformed gradually. There are two options. One is to remove the eye and have a prosthetic over an implant. The second is to get a prosthetic to wear over the current eye. The first option takes away the need for monitoring to make sure you don't develop a tumor in the sick eye (a possibility) but exposes to the risks of an implant (exposure, infection, etc.). You need to discuss these options with an orbital or oculoplastic surgeon if you are unhappy with the eye's appearance and your doctors should not hesitate to refer you to one now so you can plan accordingly.
