capsule

1. an enclosing structure, as a soluble container enclosing a dose of medicine.
2. a cartilaginous, fatty, fibrous or membranous structure enveloping another structure, organ or part.

adipose renal capsule
the investment of fat surrounding the fibrous capsule of the kidney, continuous at the hilus with the fat in the renal sinus.
articular capsule
the saclike envelope that encloses the cavity of a synovial joint by attaching to the circumference of the articular end of each involved bone.
bacterial capsule
a gelatinous layer of polysaccharide surrounding a bacterial cell, usually polysaccharide but sometimes polypeptide in nature; it inhibits phagocytosis and is associated with the virulence of pathogenic bacteria.
Bowman's capsule
glomerular capsule.
brain c's
two layers of white matter in the substance of the brain. See also external capsule (below) and internal capsule (below).
external capsule
the layer of white fibers between the putamen and claustrum.
fibrous renal capsule
the connective tissue investment of the kidney, which continues through the hilus to line the renal sinus.
Glisson's capsule
a sheath of connective tissue accompanying the hepatic ducts and vessels within the liver.
glomerular capsule
the globular dilatation forming the beginning of a uriniferous tubule within the kidney, and surrounding the glomerulus. Called also Bowman's capsule and malpighian capsule.
heart capsule
pericardium.
internal capsule
the fanlike mass of white fibers separating the lentiform nucleus laterally from the head of the caudate nucleus, the dorsal thalamus, and the tail of the caudate nucleus medially.
joint capsule
articular capsule.
lens capsule
the elastic sac enclosing the lens of the eye.
malpighian capsule
see glomerular capsule (above).
Tenon's capsule
the connective tissue enveloping the posterior eyeball. Called also vagina bulbi.

The wrinkle is so common that it's called the "in the bag sign," an indicator that the lens is resting properly within the lens capsule, yet few people complain about it.

One of the most common treatments of cataract associated with aniridia is phacoemulsification, always bearing in mind the fragility of the lens capsule and the possibility of tear during the surgical procedure.
True exfoliation can be defined as a separation of the anterior lens capsule from its deeper layers.

Photopolymerization is one of the most easily controlled ways, through which liquid artificial materials could be solidified within a short period in a transparent lens capsule only by controlling the light radiation on or off (1), (11).
After the IOL implantation, a clouding of the lens capsule, known as a "secondary cataract," occurs in roughly 40 percent of cases.

Age-related Account for 95 percent of cataract cases; occur with normal aging of the eye, usually after age 40 Congenital Present at birth, usually caused by infection or inflammation during pregnancy; possibly inherited Traumatic Due to lens damage caused by a hard blow, cut, puncture, intense heat or chemical burn Secondary Caused by certain medications, eye disease or infection, or systemic diseases such as diabetes; also can occur after cataract surgery if the remaining lens capsule becomes cloudy
RESCULA should be used with caution in aphakic patients, in pseudoaphakic patients with a torn posterior lens capsule, or in patients with known risk factors for macular edema.
The caveat here is that rotational alignment of these lenses either fixated to the iris or in the ciliary sulcus is not quite as stable as an 'in the bag' toric IOL as used in cataract surgery or refractive lens exchange surgery the reason for this is that fibrosis of the lens capsule tends to 'lock' the in-the-bag IOL in place in the weeks that follow surgery.
In pseudoexfoliation (PEX) syndrome, extracellular fibrillary material is deposited throughout the anterior segment, particularly over the anterior lens capsule in a characteristic double concentric ring pattern with a clear zone between the rings.
