Had a head injury in 2003 which caused a left temporal lobe fracture which fractured my cribriform plate and radiated down my my left eye orbit. I had metal plates put in along with a craniotomy with no eye symptoms since then. However, in 2006 I was hit with a blunt object around my eyes. In 2010, my eyes have lost volume themselves (not the eye fat) up until 2019. Steroid eyedrops and antibiotics have not stopped the loss of volume. How can I go about asertaining the cause of this volume loss?The eyes have progressively become smaller with a more cuboidal appearance. No redness, but I do have blepharitis along with meibomian gland dysfunction with acidic, white discharge upon waking up in the morning which causes a burning sensation. Eyelids are slightly swollen with a non-burning "soapy/bubbly" discharge on the eyelids and moderately dry eyes, and the gap of the fracture above the left eye seems to have opened more wide over time. I dont know if the open fracture could have cause cross-contamination. Would a B-scan ultrasonagraphy be a good start to ascertain what's going on in the eyes? CT scans just show mucousal thickening in ethmoid sinuses and a CSF leak is a possibility, Onodi cells were noted, along with fractures stated above. Not looking for an exact diagnosis just theories, considering the limitations over the internet. Thank you.
