Case 6: Comparison of GCC and OCT/GDx RNFL
The GCC, OCT and GDx appear normal in the OD. In contrast, the GCC, OCT and GDx are all abnormal superiorly in the OS. Central corneal thickness is quite normal at about 555um OU. Since the patient never had Goldmann IOPs higher than 16 and the cups are not obviously glaucomatous in appearance, a workup for non-glaucomatous optic neuropathies was obtained. All tests to date (including an MRI, CBC, FA etc) have been normal. Non-arteritic AION is a consideration. The patient is being treated as having normal tension glaucoma and is being monitored carefully for change.
