Purpose: To present a clinical case exemplifying the diagnosis and treatment of NTG. Materials and Methods: The patient underwent assessment of the level of visual acuity, ophthalmoscopy, intraocular pressure and visual field examination, and optical coherent tomography (OCT). Results: The patient was diagnosed with NTG. The clinical diagnosis was confirmed by examinations performed (i.e., ophthalmic rheography, OCT, visual field perimetry and ocular tonography).
