The purpose of these two case reports is to emphasize the clinical characteristics and differential diagnostic considerations. The first case discusses the clinical features of a normal tension glaucoma case with normal cranial imaging findings. The second case highlights the association of a compressive intracranial mass causing asymmetric disc cupping and normal IOP readings. The differential diagnosis of this case is discussed.
