Eye histology





















Lacrimal Gland

Anterior portion of the lens. The subcapsular epithelium secretes the lens capsule, which appears stained in red. The lens capsule is a thick basement membrane containing collagen type IV and laminin. Below the subcapsular epithelium, note the lens fibers, which are cells that have lost their nuclei and organelles, becoming thin, elongated, transparent structures

LENS:

The subcapsular epithelium secretes the lens capsule, which appears stained in red. The lens capsule is a thick basement membrane containing collagen type IV and laminin. Below the subcapsular epithelium, note the lens fibers, which are cells that have lost their nuclei and organelles, becoming thin, elongated, transparent.
subcapsular epithelium is single layer of cuboidal epithelial cells that is present only on the anterior surface of the lens.

CLINICAL:

When the lens becomes opaque, the condition is termed cataract, which may also be caused by excessive exposure to ultraviolet radiation. In diabetes mellitus, the high levels of glucose are believed to produce cataract.
