Red and Ruptured
Canine globe with chronic intralenticular hemorrhage, evidenced grossly as red discoloration within the lens capsule. Histologically, blood vessels extended into the lens and percolated through the hemorrhage. The lens capsule was also ruptured and there was a granulomatous phakitis. The blood vessels extending from the optic nerve head remain unidentified. A diagnosis of persistent fetal vasculature (persistent hyperplastic tunica vasculosa lentis and/or persistent hyperplastic primary vitreous) was made.

Chamber Cleavage Anterior segment abnormalities can be seen in this canine globe with anterior chamber cleavage syndrome. The small, malformed lens blends with the posterior cornea. Additionally, the iridocorneal angle structures (ciliary cleft and trabecular meshwork) were malformed with no aqueous humor outflow tracts, which was termed anterior segment dysgenesis.

Revealing Retinoschisin An essential adhesion protein in the retina, the loss of retinoschisin results in a form of macular degeneration in young males called X-linked retinoschisis. Bernard Heymann, NIH.

Cilia and Cilia The cellular structure in photoreceptors that capture light is derived from a modified cilium. Fluorescent labeling for RPGR, a protein commonly mutated in retinitis pigmentosa, shows the photoreceptor cilia (red) within the mouse retina. Additional ciliary structures (green), the ciliary rootlet (white), and nuclei (blue) are also visualized. Jessica Gumerson, National Eye Institute/NIH.
