title: Long term fixation for histological studies.
abstract: It was found that a glutaraldehyde-formalin-phosphate buffered fixative could preserve retinal tissue for light microscopy, even if the tissue remained in the fixative for a month. Retinal tissue that previously was difficult and expensive to procure could now be obtained.
