Erratum to dimensions of the optic chiasm: ultrasound quantitative comparison between fetuses with anophthalmia/microphthalmia and normal fetuses

Erratum to Quant Imaging Med Surg 2021;11:4389-98

This article (1), that appeared on page 4389-4398, Vol 11, No10 Issue of Quantitative Imaging in Medicine and Surgery, unfortunately contained two mistakes on page 4391 in the first paragraph of the results section. Namely, “44 normal fetal ONs” should be corrected to “51 normal fetal ONs” and “18 fetuses” should be corrected to “25 fetuses”.

The related sentences after correction are presented as follows:

“However, 51 normal fetal ONs were unable to be clearly displayed. Of these, 26 fetal ONs that we failed to measure successfully had shadowing from the sphenoid bone (median GA of 35⁺⁶, range: 33⁺¹ to 39⁺⁶). The GA of a further 25 fetuses was too early to distinguish the ON, or the fetuses were in an unsuitable position (angle to occiput anterior).”

The authors regret the errors.
