Article
Optic disc drusen (ODD) are calcified masses in the prelaminar optic nerve head seen in up to 2% of the population. Although the pathophysiology is not fully understood, altered microvascularization could both be part of the pathogenesis and a consequence of ODD.[1] We developed a method that combines information from optical coherence tomography (...
Article
Optical coherence tomography angiography (OCTA) is a rapidly developing technique which generates angiographic images non-invasively. This study proposes a method to determine the vessel density in OCTA scans in general and especially the local peripapillary vessel density. The method produces vessel density heatmaps that contain information about...
Article
Background: Nonarteritic anterior ischemic optic neuropathy (NAION) in young patients (age ≤50) accounts for a minority of all cases of NAION and is more highly associated with crowding of the optic nerves and bilateral involvement than NAION in older patients. Optic disc drusen (ODD) are likewise associated with crowded optic nerves and are locat...
Article
Background: Nonarteritic anterior ischemic optic neuropathy (NA-AION) associated with optic disc drusen (ODD) is termed ODD-AION, where NA-AION with no evidence of ODD is simply termed NA-AION. Patients with ODD-AION have been found to be younger than those with NA-AION but with similar vascular risk factors. This study compares the known risk fac...
Article
The aim was to analyse the optic disc angioarchitecture in optic disc drusen (ODD) patients using computer-based fundus analysis in a case–control study. Compared with controls the ODD group had a significantly more centralised central retinal artery (CRA) emergence (p < 0.001) and primary CRA branching (p = 0.008), a higher number of CRA bifurcati...
