Optic Nerve Head Drusen: Imaging Using Optical Coherence Tomography Angiography
Flores-Reyes E; Hoskens K; Mansouri KJournal of Glaucoma 2017; 26: 845-849
PURPOSE: To describe findings and utility of optical coherence tomography angiography (OCTA) in optic nerve head drusen (ONHD). OBSERVATIONS: A 57-year-old white man presented with a decrease in contrast sensitivity of the inferior visual field in both eyes. Clinical examination, visual fields, optical coherence tomography, fundus autofluorescence and OCTA revealed ONHD bilaterally. A focal decrease in vessel density within the localization of ONHD in both eyes was demonstrated suggesting a connection between those findings. CONCLUSIONS AND IMPORTANCE: This is the first report in which peripapillary vessel density is analyzed using OCTA technology for this entity. OCTA could confirm the diagnosis and has the potential to assist with the diagnosis and evaluation of progression of ONHD.
