PURPOSE Optic nerve drusen needs to be included in the differential diagnosis of pseudopapilledema. As the identification of this entity by funduscopy may be difficult, ultrasonography has thus become the gold standard for its diagnosis. Severe optic nerve drusen has been correlated with a reduction of the nerve fiber layer measured by optic coherence tomography and with the presence of serious...

OBJECTIVE To investigate the ability of optical coherence tomography (OCT) to assess changes in retinal nerve fiber layer (RNFL) thickness in optic disc edema. METHODS Prospective observational case series in a private eye clinic (Centro Salus). Twelve consecutive eyes (9 patients) with optic disc edema were analyzed, including 6 patients with anterior ischemic optic neuropathy, 1 patient wit...

Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc vessels. Recent studies have shown the ability of OCTA to visualize vascular abnormalities in different optic neuropathies. In addition, quantified ...
