Figure 1. Serial optic disc photos in a patient with pre-perimetric NTG caused by a TBK1 gene duplication.

Figure 1.

Optic disc photos obtained over 20 years demonstrate progressive cupping and progressive peripapillary atrophy in both eyes. In 2012, a disc hemorrhage was detected in the right eye at 7–8 o’clock. In 2019, increased cupping was detected in the right eye in the same location (7–8 o’clock). The configuration of retinal vessels at the optic disc was also noted to shift during course of progressive cupping.
