Retinal cancer is a cancer that arises in the cells of the retina. The retina is the layer of cells in the back of the eye where light is converted to nerve impulses.
The tumor of embryonic retinal cells is called retinoblastoma. It is a rare type of eye cancer that typically affects young children. It develops in the retina, the light-sensing tissue at the back of the eye.
Retinal veins are larger than retinal arteries. Retinal veins are between 2/3 to 3/4 times larger than the arteries of the retina. Retinal vein are also darker red then the arteries.
Surgery on the eye is routinely performed to repair retinal defects, remove cataracts or cancer, or to repair eye muscles.
retinal breaks or detachments; retinal ischemia (retinal tissue that lacks oxygen); neovascularization (proliferation of blood vessels in the retina); Coats' disease
Retinal vein occlusion refers to the closure of the central retinal vein that drains the retina or to that of one of its branches.

Multiple retinal hemorrhages-- Bleeding in the back of the eye.
Retinal artery occlusion refers to the closure of the central retinal artery and usually results in complete loss of vision in one eye.

Retinal has three isomeric forms resulting from double-bond isomerization: all-trans retinal, 11-cis retinal, and 13-cis retinal. These isomeric forms are essential in the visual cycle and play a crucial role in the mechanism of vision.
The two major RVO types are central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO).
Patients suffering from retinal detachments are commonly nearsighted, have had eye surgery, experienced ocular trauma, or have a family history of retinal detachments.
