corneal

 [kor´ne-al]
pertaining to the cornea.
corneal reflex a reflex action of the eye resulting in automatic closing of the eyelid when the cornea is stimulated. The corneal reflex can be elicited in a normal person by gently touching the cornea with a wisp of cotton. Absence of the corneal reflex indicates deep coma or injury of one of the nerves carrying the reflex arc.
corneal transplantation transplantation of a donor cornea into the eye of a recipient, done to improve the vision of patients with distorted curvature of the cornea (keratoconus) or corneal edema, infection, trauma, or intractable pain. Vision should improve beginning the day after surgery with optimal vision 6 to 12 months later. Because the cornea does not have a blood supply, corneal transplants were one of the earliest successful types of organ transplants. Called also keratoplasty.

Angiogenesis is undesirable in the cornea because the newly formed blood vessels result in not only the loss of corneal transparency but also the loss of immunological privilege of the cornea.
The transplantation of CECs in these primates also achieved the recovery of long-term corneal transparency with a monolayer of hexagonal cells, suggesting that cell adhesion modified by ROCK inhibitor may be an effective treatment for human corneal endothelial disorders.
Exposure keratitis (as assessed clinically by observation for the reduction in corneal transparency at the exposed part of the cornea) cleared in 16 out of 27 eyes (60%).
We aimed in the current study to evaluate corneal transparency and visual acuity following ACXL in pediatric keratoconus in a highly populated region with rapidly progressive keratoconus, south KSA (Kingdom of Saudi Arabia).
Only the introduction of the hypertonic solution therapy induced the improvement of visual acuity, so we hypothesize the crucial influence of pharmacological therapy to restore corneal transparency. Furthermore, in literature there are four more cases described of Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) due to bullous keratopathy after anterior-posterior radial keratotomy (APRK) as an effective surgical option [12].
of corneal transparency was constant post-operative complication in Gr-I and similar observations were also recorded by Tyagi et al.
Vessels advancing into the cornea cause corneal inflammation, scarring, edema and lipid accumulation, which can lead to reduction in corneal transparency and impaired vision; therefore, the treatment of these patients is very important.
To our knowledge, this is the first paper investigating the effects of bone marrow MSCs (BM-MSCs), adipose tissue MSCs (Ad-MSCs), or corneal limbal epithelial stem cells (LSCs) on the antioxidant protective mechanism in the regenerated corneal epithelium and on corneal optical properties evaluated by central corneal thickness (taken as an index of corneal hydration) and corneal transparency. We found that in contrast to the effect of nanofibers alone (MSCs-free), where profound enzymatic antioxidant/prooxidant imbalance was found in the corneal epithelium, after the treatment of injured corneas with BM-MSCs nanofibers or LSCs nanofibers (less after Ad-MSCs nanofibers), the enzymatic antioxidant protective mechanism was restored in the regenerated corneal epithelium.
The endothelium is a single layer of juxtaposed cuboidal cells with pale and granular cytoplasm, which act in the transport of fluids and maintenance of corneal transparency (SAMUELSON, 2007; RODRIGUES, 1999; GALERA et al., 2009).
Corneal Endothelial Examination: Corneal endothelium is the primary layer responsible for maintaining the corneal transparency and tugor hence assessment of this layer forms a crucial step in determining the corneal graft survival.
For example, UCB-MSCs have been transplanted into corneas of mice leading to improved corneal transparency and increased stromal thickness [68], and autologous bone marrow MSCs have been used to replace corneal endothelium of rabbits in vivo [72].
