  • precut
  • The rapid success and utilization of this procedure can be attributed to availability of eye-bank prepared precut tissue. (jove.com)
  • collagen
  • Retention of corneal architecture, collagen and glycosaminoglycans was assessed via histological, immunofluorescence and quantitative analysis. (lboro.ac.uk)
  • A bi-functional epoxy-based cross-linker, 1,4-Butanediol diglycidyl ether (BDDGE), was investigated in the fabrication of collagen based corneal substitutes. (mdpi.com)
  • Characteristics
  • Characteristics of Pseudomonas corneal infection related to orthokeratology. (medscape.com)
  • Thus, the sequential dynamic culture process that was designed according to corneal physiological characteristics could successfully reconstruct an auto-lamellar cornea with favorable morphological characteristics and satisfactory physiological function. (jove.com)
  • To assess characteristics of donor corneal tissues with positive scleral rim cultures and postkeratoplasty infections. (arvojournals.org)
  • Data collected included: donor cornea characteristics from the eye-bank database, surgery performed, microbiology laboratory reports, and post-operative course. (arvojournals.org)
  • There were no statistically significant differences in donor characteristics of the tissues with positive scleral rim cultures or postkeratoplasty infections, including age, sex, race, death to procurement time, or death to surgery time. (arvojournals.org)
  • peripheral
  • Compared with the peripheral corneal limbus, the human central cornea lacks blood vessels, which is responsible for its immunologically privileged status and high transparency. (jove.com)
  • shortage
  • Reprocessing the tissue has the potential to have a considerable impact on addressing the problems associated with cadaveric donor shortage. (lboro.ac.uk)
  • synthetic
  • Decellularized tissues are advantageous compared to synthetic or semi-synthetic engineered tissues in that the native matrix ultrastructure and intrinsic biological cues including growth factors, cytokines and glycosaminoglycans may be retained. (lboro.ac.uk)
  • abnormal
  • Schnyder crystalline corneal dystrophy (SCCD) is a rare autosomal dominant stromal dystrophy that is characterized by bilateral corneal opacification, resulting from an abnormal accumulation of cholesterol and lipid. (medscape.com)
  • years
  • A long-term study of 33 families over a period of 18 years reveals that most morbidity derives from progressive corneal clouding, leading to glare and decreased vision in daylight. (medscape.com)
  • vision
  • Nevertheless, while scotopic vision remained relatively good, increasing corneal opacification with age resulted in decreased scotopic vision. (medscape.com)
  • immune
  • which should balance effective removal of immune reactive material with maintenance of tissue functionality. (lboro.ac.uk)
  • This model has been used to define factors in the cornea that are responsible for the relative immune privilege status of this tissue that enables corneal allografts to survive acute rejection in the absence of immunosuppressive therapy. (jove.com)
