Artifacts and main lesions in fetal ocular histology - 11/05/23
Lésions artéfactuelles et principales lésions oculaires fœtales

Highlights |
• | Histological analysis of fetal eyes is systematically artefacted. |
• | Knowing the causes, effects and appearance of artifacts minimize the risk of avoidable artifacts and help to distinguish them from “true” pathological lesions. |
• | Given the wide variety of artifacts, the interpretation of fetal eye lesions must be done with caution and with a very critical “eye”. |
• | The distinction between true lesions and artifacts requires a great experience and must be based on macroscopic exam in association with histological analysis and the help of a bank of reference tissue images of different fetal ages. |
Summary |
Histological artifacts in fetal eyes can involve different tissues and can be related to mechanical or autolytic lesions, fixation, the cause of death or the cutting technique. Knowing the causes, effects and appearance of artifacts allow the minimization of the risk of avoidable artifacts and help distinguish them from “true” pathological lesions. We describe these different types of artifacts and specifically analyze their involvement in different tissue structures of the eye. We compare them with primary fetal ocular lesions. Given the wide variety of artifacts, the identification of lesions in fetal eyes must be done with caution, since differentiating true lesions from artifacts requires some experience and relies on both macroscopic examination and microscopic analyses, with ideally comparisons with references’ images of normal tissues of the same gestational age.
