Occasionally, not all the edema is gone from the orbit at the time of an original prosthetic fitting. As the edema disappears, which may take several months to a year, the artificial eye may sink deeper in the eye socket and the upper eyelid may droop over the eye.
Whenever this becomes noticeable it would be best to add material to the eye beginning with a new impression taken on the back of the prosthesis.
As I already noted earlier, slow atrophy of fat from deep in the orbit can require the same kind of refitting as above. Occasionally, a person will have a sudden extreme loss or gain of body weight which will be accompanied by sinking back or other changes in the socket of the eye, requiring refitting of the prosthesis.
It is best to consult your eye doctor with any noticeable increase in tearing form the eye socket, with any marked loss or reduction of comfort, with excessive persistent mucoid discharge or with an easily recognized bulging out of the artificial eye. If there is an implant present, bulging could indicate extrusion or migration and should call for immediate attention.
Some problems require the cooperative efforts of both the doctor and ocularist. Call our office, at Alamance Eye Prosthetics, we are glad to answers any question you may have.
