HVF results on the initial encounter. HVF 24-2 results appeared normal in the right eye (a) and left eye (b). However, an HVF 10-2 showed an abnormal scotoma in the right eye in the paracentral region (c) that matched the patient's visual complaint and a normal result in the left eye (d).

Although a Humphrey visual field (HVF) 24-2 yielded nearly normal results (including a visual field index of 99%) in her right eye, an HVF 10-2 showed a prominent scotoma in the paracentral region that corresponded to the appearance of the "blind spot" (shown in Fig. 1).
Nerve OCT results on the initial encounter. Superior RNFL loss can be seen in both eyes (a), and marked ganglion cell loss can be seen superiorly in the right eye (b). RNFL, retinal nerve fiber layer.

Marked superior retinal nerve fiber layer loss seen on the nerve optical coherence tomography (OCT) for her right eye and superotemporal loss ganglion cell loss corresponded to the inferior location of her scotoma (shown in Fig. 2a, b).

HVF 30-2 results showed nonspecific loss in the right eye (a) and a paracentral scotoma in the left eye (b). HVF 10-2 results upon initial evaluation with the glaucoma service. c Right eye showed nonspecific loss. d Marked central scotoma in the left eye was seen, reflecting the patient's visual complaints. Analysis of RNFL (e) and ganglion cell analysis showing marked loss of ganglion cells can be seen particularly temporally, reflecting the patient's visual complaints (f). RNFL, retinal nerve fiber layer.

Patient stated that when he looked at the Snellen vision chart, there were "letters missing" in his left eye but the rest of the chart appeared clear which reflects in his HVF 30-2 testing (Fig. 3a, b). An HVF 10-2 showed a focal central scotoma in the left eye within one degree of central vision (shown in Fig. 3c, d). The patient's nerve OCT showed asymmetric optic nerves with a larger cup within a small disc in the left eye and thinner neuroretinal rims (shown in Fig. 3e). There was marked ganglion cell loss, more in the left eye than in the right (shown in Fig. 3f).
