We thank Dr Grzybowski for his interest in our paper. 1 Uji A. Yoshimura N. Microarchitecture of the vitreous body: a high-resolution optical coherence tomography study.

However, several books that associate the work of Pappenheim with the word "onion" or that did not associate the work of Zinn with onion were found. An article in the London Journal of Medicine: A Monthly Record of the Medical Sciences (1852) mentioned: "Pappenheim, however, in 1842, announced that the vitreous body,4 London Journal of Medicine A Monthly Record of the Medical Sciences.

Bowman (1892), as pointed out by Dr Grzybowski. This suggests that information from earlier studies compiled and presented in articles or books should be verified by referring to multiple books and original articles, and each manuscript has the responsibility to disseminate historical evidence accurately. Again, we thank Dr Grzybowski for bringing this issue to our attention. Microarchitecture of the Vitreous Body: A High-Resolution Optical Coherence Tomography StudyAmerican Journal of OphthalmologyVol. 170PreviewI read with great interest the article by Uji and Yoshimura1 on new and original observations of microarchitecture of the vitreous body. The authors wrote: "these findings are consistent with the theory proposed by Zinn in 1780, which states that the vitreous is arranged in a concentric, lamellar configuration, similar to that observed in a cut onion." This statement has been made previously.2,3 Johann Gottfried Zinn (1727–1759) published his treatise "Descriptio anatomica oculi humani," considered to be the first complete description of the eye's anatomy, in 1755, with a second edition in 1780.
