The study focuses on adult zebrafish that are blind due to mutations in the atoh7 gene, which prevents the formation of retinal ganglion cells (RGCs).
Researchers characterized the physical and behavioral traits of these mutants using various scientific techniques, noting distinct characteristics like dark pigmentation and reduced body size.
The findings highlight that these adult zebrafish serve as a valuable model for studying conditions like glaucoma and optic nerve aplasia by providing insights into retinal and tectal structure.
