Figure 5.

Orbital fat volume (OFV) (A) OFV in controls and patients with POAG without abnormally elevated IOP who were treated with topical PGAs. While total OFV from apex to trochlea in POAG was significantly less in patients than controls (left paired columns), the difference was driven by the posterior orbit from apex to the GONJ (middle paired columns). In the anterior orbit from the GONJ to the trochlea (right paired columns), OFV was similar in the two groups. (B) Total orbital volume (OV) of patients with POAG was significantly less than in controls. SD, standard deviation; N.S., not significant.
