• Collagen
  • In this study, the organization of collagen fibrils within the sclera of the eye was investigated using the 7 keV hard X-ray microscope of the Pohang light source and compared to images from electron and atomic force microscopy. (lancs.ac.uk)
  • lamina
  • The nerve fibers forming the optic nerve exit the eye posteriorly through a hole in the sclera that is occupied by a mesh-like structure called the lamina cribrosa. (wikipedia.org)
  • iris
  • think(from the pictures)that the grey patches started showing up on the beggining of last year!before her eyes were white and pretty,now they are mostly grey with veins(must check that with doctor) but month ago I noticed that under and above the iris the sclera is getting blue! (medhelp.org)
  • thank you for your answer you wrote that if it would be a blue sclera there would be a diffuse and generalized blueness to her sclera but she already got some hints of blue under and above the iris on her sclera! (medhelp.org)
  • In humans, the whole sclera is white, contrasting with the coloured iris, but in other mammals the visible part of the sclera matches the colour of the iris, so the white part does not normally show. (wikipedia.org)
  • The human eye is relatively rare for having an iris that is small enough for its position to be plainly visible against the sclera. (wikipedia.org)
  • This is not just due to the white color of the human sclera, which many other species share, but also to the fact that the human iris is relatively small and comprises a significantly smaller portion of the exposed eye surface compared to other animals. (wikipedia.org)
  • tissue
  • 1 Recent research has shown that the sclera is a dynamic tissue, capable of responding rapidly to changes in the visual environment to alter ocular size and refraction. (arvojournals.org)
  • Although tissue-specific postnatal stem/progenitor cells have been isolated from a variety of organs and tissues, it is still unknown whether the sclera contains these subsets of cells. (arvojournals.org)
  • extraocular
  • The sclera maintains the shape of the globe, offering resistance to internal and external forces, and provides an attachment for the extraocular muscle insertions. (wikidoc.org)
  • Usually, these implants are covered with a material that permits fixation of the extraocular recti muscles, such as donor sclera or polyester gauze which improves implant motility, but does not allow for direct mechanical coupling between the implant and the artificial eye. (wikipedia.org)
  • membrane
  • A second type of eye, called schizochroal, is unique to the Phacopina suborder, and has up to several hundreds of relatively large lenses (0.05-0.5 mm), that do not touch either, but the corneal membrane extends into the sclera outside the lens, and the sclera is deeper than the lens. (wikipedia.org)
  • species
  • Trachypollia sclera is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails. (wikipedia.org)
  • redness
  • In relation to the sclera, an allergic reaction may cause redness on the white of your eye. (livestrong.com)
  • In hyperemia, there is a visible increase in the blood flow to the sclera (hyperaemia), which accounts for the redness of the eye. (wikipedia.org)
  • human eye
  • It is believed that the conspicuous sclera of the human eye makes it easier for one individual to infer where another individual is looking, increasing the efficacy of this particular form of nonverbal communication. (wikipedia.org)
  • The bony area that makes up the human eye socket provides exceptional protection to the sclera. (wikipedia.org)
  • visible
  • The eyes of all non-human primates are dark with small, barely visible sclera. (wikipedia.org)
  • Human eyes are somewhat distinctive in the animal kingdom in that the sclera is very plainly visible whenever the eye is open. (wikipedia.org)
  • eyes
  • what cause the sclera of the eyes to turn brown? (medhelp.org)
  • The sclera of my eyes have turned brown in tint after sleeping they are very red, eye drops only get the red out. (medhelp.org)
  • however
  • However, if the sclera is ruptured by a blunt force or is penetrated by a sharp object, the recovery of full former vision is usually rare. (wikipedia.org)
  • changes
  • If you notice changes in the color of your sclera, contact your doctor. (livestrong.com)
  • As additional information accumulates about changes in gene expression that occur during compensation and recovery the "signature" of differential changes may help us to understand in more detail how the sclera responds in "go" and "stop" conditions. (molvis.org)
