In the development of the embryo, the sclera is derived from the neural crest. [3] In children, it is thinner and shows some of the underlying pigment, appearing slightly blue. In the elderly, fatty deposits on the sclera can make it appear slightly yellow. People with dark skin can have naturally darkened sclerae, the result of melanin ...
There is a growing body of evidence for the association between xanthelasma deposits and blood low-density lipoprotein levels and increased risk of atherosclerosis. [3] [4] A xanthelasma may be referred to as a xanthoma when becoming larger and nodular, assuming tumorous proportions. [5] Xanthelasma is often classified simply as a subtype of ...
It is seen as a yellow-white deposit on the conjunctiva adjacent to the limbus (the junction between the cornea and sclera). [3] (It is to be distinguished clinically from a pterygium, which is a wedge shaped area of fibrosis that may grow onto the cornea.) A pinguecula usually does not cause any symptoms.
Scleritis is a serious inflammatory disease that affects the white outer coating of the eye, known as the sclera.The disease is often contracted through association with other diseases of the body, such as granulomatosis with polyangiitis or rheumatoid arthritis.
[27] [28] The technique usually involves making three openings through the part of the sclera known as the pars plana. Of these small gauge instruments, one is an infusion port to resupply a saline solution and maintain the pressure of the eye, the second is a fiber optic light source, and the third is a vitrector.
In severe cases, it is manifested as jaundice, the yellowing of tissues like skin and the sclera when excess bilirubin deposits in them. [1] The US records 52,500 jaundice patients annually. [ 2 ] By definition, bilirubin concentration of greater than 3 mg/dL is considered hyperbilirubinemia, following which jaundice progressively develops and ...
The episclera is the outermost layer of the sclera (the white of the eye). [1] It is composed of loose, fibrous, elastic tissue and attaches to Tenon's capsule. [1]A vascular plexus is found between the bulbar conjunctiva and the sclera consisting of two layers of vessels, the superficial episcleral vessels and the deep episcleral vessels.
Tenon's capsule (/ t ə ˈ n oʊ n /), also known as the Tenon capsule, fascial sheath of the eyeball (Latin: vagina bulbi) or the fascia bulbi, is a thin membrane which envelops the eyeball from the optic nerve to the corneal limbus, separating it from the orbital fat and forming a socket in which it moves.
