In the original publication of this article [1] the algorithm of the OCTA (Nidek RS-3000) was described incorrectly as OMAG (Optical micro angiography). However, the system uses CODAA(Complex OCT signal difference angiography). Thus, ‘OMAG’ in the article should be replaced with ‘CODAA’, and ‘Optical micro angiography’ should be replaced with ‘Complex OCT signal difference angiography’!
