Serial optic disc photo and SAP results of the right eye. There is progressive inferior neuroretinal rim thinning over time with an associated optic disc hemorrhage. SAP global indices remained within normal limits throughout the follow-up period.

For the next 16 years, IOPs were consistently in the mid-teens and optic disc and SAP parameters remained normal; however, in 2009, changes to the right optic disc were noted (fig. 1).

Comparison between SAP, FDT and HEP. The HEP defect was more extensive than the defect observed on FDT and agreed closely with the retinal nerve fiber layer assessment by SD-OCT.

Figure 3 compares SAP, frequency doubling technology (FDT) and HEP, which were completed on the same day. There was also a good spatial correlation between the defect on the Heidelberg Edge Perimeter and the defect observed on optic disc photographs and SD-OCT (fig. 3).

HEP results of the right eye showing extensive superior visual field damage in agreement with optic disc and retinal nerve fiber layer assessment.
