This method for evaluating the quality of a transplant neural retina includes: extracting, as a quality evaluation sample, a portion of or all of a cell aggregate that contains a neural retina having an epithelial structure derived from pluripotent stem cells； detecting, in the quality evaluation sample, the expressions of genes related to neural-retina-based cells and genes related to non-neural-retina-based cells； and, in the case in which the expressions of the genes related to the neural-retina-based cells are recognized and the expressions of the genes related to the non-neural-retina-based genes are not recognized, determining that it is possible to use, as the transplant neural retina, (1) a neural retina (transplant neural retina) in a cell aggregate that is the same as the cell aggregate that contains the quality evaluation sample as a portion thereof, (2) a neural retina (transplant neural retina) in a cell aggregate of the same lot as the cell aggregate that contains the quality evaluation sample as a portion thereof, or (3) a neural retina (transplant neural retina) in a cell aggregate of the same lot as the cell aggregate the entirety of which is the quality evaluation sample. The genes related to non-neural-retina-based cells are one or more types of genes selected from the group consisting of cerebrospinal tissue marker genes and eye-related tissue marker genes.L'invention porte sur un procédé d'évaluation de la qualité d'une rétine neurale de transplantation comprenant les étapes suivantes consistant à : extraire, en tant qu'échantillon d'évaluation de la qualité, une partie ou la totalité d'un agrégat cellulaire qui contient une rétine neurale possédant une structure épithéliale dérivée de cellules souches pluripotentes ； détecter, dans l'échantillon d'évaluation de la qualité, les expressions de gènes associés à des cellules à base de rétine neurale et de gènes associés à des cellules à base de rétine non neurale ； et, dans le cas où les expression
