13 cze 2001 · These Y-shaped lines are often called the sutures of the lens. The lens is enclosed in a capsule that, if disrupted, allows the immune system to see the lens proteins for the first time, recognize them as foreign, and attack.
13 cze 2001 · The fibers making up the lens come together in the center of the lens, forming a “Y” shape that is sometimes visible when one looks into the eye. These Y-shaped lines are often called the sutures of the lens.
In human, dogs, and cats these suture lines are in a Y-shape, upright anteriorly and inverted posteriorly, but this varies with other species. This results in a layered arrangement of the lens fibers with the oldest fibers in the center and the newest fibers surrounding them.

13 wrz 2024 · Like us, the feline eye contains a lens; this lens allows cats (and us) to focus more on objects that are at a distance. This process is called “accommodation.” In humans, this is achieved through slight changes in the lens curvature; our lenses become flatter or rounder when the object is far away or close, respectively.
8 sie 2024 · The lens sits behind the iris and adjusts its shape to focus light onto the retina. Lens movement is largely controlled by the ciliary muscles, which contract when cats focus on nearby objects. Retina and Tapetum Lucidum. The retina’s photoreceptor cells pick up light and translate it into electrical impulses.
