Correlation of Retrobulbar Volume Change With Resected Orbital Fat Volume and Proptosis Reduction After Fatty Decompression for Graves Ophthalmopathy

Fatty decompression can reduce proptosis for patients with disfiguring Graves ophthalmopathy. Because of the close correlation of retrobulbar volume change with volume of resected orbital fat and proptosis reduction, we propose that orbital fat removal may be accompanied by decreased retrobulbar volume after fatty decompression. Evidence of decreased retrobulbar volume may result in effective proptosis reduction.
