Vahlgren J, Malmqvist L, Rueloekke L, Karlesand I, Lindberg A-S, Hamann S. The angioarchitecture of the optic nerve head in patients with optic disc drusen. Neuro-Ophthalmology, DOI: 10.1080/01658107.2019.1613666, 2019

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 bifurcations (p = 0.02), a larger vertical optic disc diameter (p = 0.02) and a smaller cup/disc ratio (p < 0.001). The CRA emergence was largely within the nasal zone for both groups. The distinctive angioarchitecture of the optic disc in ODD patients can play a role in understanding the pathogenic cause of ODD.
