Scleral hyaline plaque is a result of an age-related hyaline degeneration of the sclera and is usually asymptomatic. Given the fact that the regenerative capacity of the cartilage is limited, cartilage degeneration or loss can result in significant morbidity. Edema is not a phenomenon of degeneration but is a common histopathologic finding, present in about 50% of leiomyomas ( , 1 ). Hyaline Degeneration Substances that have a homogenous glassy appearance in tissue sections are described as hyaline. Hyaline degeneration may occur in fibrous tissue in scars and some tumours due to the deposition of glycoproteins between collagen bundles. Hyaline Degeneration. Most hyaline degeneration was seen predominantly in the middle layer of the tendon. Structure: consist of a mucoprotein matrix of Tamm-Horsfall proteins; Microscopy: homogeneous, transparent, and eosinophilic; Granular casts: caused by degeneration of cells in RBC or WBC casts. Dry macular degeneration may first develop in one or both eyes and then affect both eyes. It is found between the ribs, around the windpipe, and between the joints (articular cartilage). Definition : The term "hyaline" usually refers to an alteration within cells or in the extracellular space, which gives a homogeneous, glassy, pink appearance in routine histologic sections stained with hematoxylin and eosin. The lesions are described as bilateral, symmetric, well-defined, and with a vertically ovoid shape. 2020 Jun 1;129:109097. doi: 10.1016/j.ejrad.2020.109097. Myxoid degeneration was localized extensively in the middle to deep layers of the tendon along with the thin and disoriented collagen fibers. The degeneration of follicular arteries, vasculitis of larger vessels, and inflammation of the capsule evidently make the spleen susceptible to rupture. The common types of degeneration are hyaline, cystic, myxoid, and red. It causes blurred or reduced central vision, due to thinning of the macula (MAK-u-luh). Chondroid metaplasia was observed frequently at the same sites as hyaline degeneration . Spectrum of Common and Uncommon Causes of Knee Joint Hyaline Cartilage Degeneration and Their Key Imaging Features Eur J Radiol . EXTRACELLULAR HYALINE (connective tissue) Hyaline degeneration of uterus (Leiomyoma) Hyalinised old scar of fibrocollagenous tissue Hyaline arteriosclerosis in renal vessels in HT& DM Hyalines glomeruli in CGN Corpora amylacea seen in elderly, in brain spinal cord of old age, old infarcts in lung 58. The scleral area affected becomes thin and slightly depressed. This degenerative process can cause calcium deposition leading to calcification. Hyaline articular cartilage is a unique specialized connective tissue that facilitates smooth kinematics, load distribution and subchondral bone protection. When the cushions wear away, the bones can start to rub together. It … The degeneration develops over time. Hyaline degeneration 59. Hyaline cartilage – springy, tough, and elastic. The macula is the part of the retina responsible for clear vision in your direct line of sight. The mechanism of damage to the arteries in the follicles is unclear; however, interaction of many factors might be involved. It can cause hyaline degeneration. Hyaline casts: nonspecific finding; can also be found in healthy individuals, often after exercise . Dry macular degeneration is a common eye disorder among people over 50. It affects the rubber-like disks between vertebrae — the small bones that make up the spinal column (backbone). Learn some of the symptoms and how to get diagnosed. Detecting calcification of the uterus is very important because if gone untreated it can lead to more serious problems. The disks act like cushions between those bones.
