Source 1.5 year female domestic short hair cat, OD
Fixative glutaraldehyde
Stain azure II-methylene blue
Notes The tissue came from a region a disk diameter below the optic disk and near the ora serrata medially. The retinal epithelium to the left of the arrowhead is normal, whereas to the right it is amelanotic; this appeared as a discrete retinal epithelial coloboma ophthalmoscopically; the remainder of the tissues is normal; this was an incidental finding in this cat
