OBJECTIVE The main objectives for this evidence-based analysis were to determine the safety and effectiveness of photochemical corneal collagen cross-linking with riboflavin (vitamin B(2)) and ultraviolet-A radiation, referred to as CXL, for the management of corneal thinning disease conditions. The comparative safety and effectiveness of corneal cross-linking with other minimally invasive trea...

Healthy corneal endothelium is essential for maintaining corneal clarity, as the damage of corneal endothelial cells and loss of cell count causes severe visual impairment. Corneal transplantation is currently the only therapy for severe corneal disorders. The greatly limited proliferative ability of human corneal endothelial cells (HCECs), even in vitro, has challenged researchers to establish...

Biomechanics is the study of the relationship between forces and function in living organisms and is thought to play a critical role in a significant number of ophthalmic disorders. This is not surprising, as the eye is a pressure vessel that requires a delicate balance of forces to maintain its homeostasis. Over the past few decades, basic science research in ophthalmology mostly confirmed tha...

Stromal corneal dystrophies are a group of hereditary disorders caused by mutations in the TGFBI gene. The mutant TGFBIp is prone to protein aggregation and gets deposited cornea, leading severe visual impairment. lead specific suggesting involvement tissue-specific factors. exact molecular mechanism process remains be elucidated. Differential proteolysis critical component disease pathology. d...

We were very interested to read of a second mutation in the seed region of miR-184 resulting in EDICT syndrome. We were unsure after reading the paper, however, of how the corneal findings should be classified and of the statement that the family “does not demonstrate a keratoconus phenotype.” Keratoconus, the commonest disorder of corneal thinning and steepening, has been linked with VSX1 and ...

BACKGROUND The recent availability of genetic analyses has demonstrated the shortcomings of the current phenotypic method of corneal dystrophy classification. Abnormalities in different genes can cause a single phenotype, whereas different defects in a single gene can cause different phenotypes. Some disorders termed corneal dystrophies do not appear to have a genetic basis. PURPOSE The purpo...

BACKGROUND/AIMS To determine outcomes of transplants of cultivated autologous oral epithelial cells in patients with severe ocular surface disorders. METHODS The eyes (n = 6) of four patients with Stevens-Johnson syndrome (three eyes) or chemical burns (three eyes) were studied. Autologous oral epithelial cells, grown for 2-3 weeks on a denuded amniotic membrane carrier in the presence of 3T3...

BACKGROUND Euphrasia officinalis L. is an herb traditionally used in folk medicine, mainly in the treatment of eye disorders. AIMS The present study analyzed the activity of three extracts of E. officinalis L. (ethanol, ethyl acetate and heptane) on cultured human corneal epithelial cells (10.014 pRSV-T). STUDY DESIGN In vitro study. METHODS Toxicity, free radical scavenging activity and ...

Angiogenesis is beneficial in the treatment of ischemic heart disease and peripheral artery disease. However, it facilitates inflammatory cell filtration and inflammation cascade that disrupt the immune and angiogenesis privilege of the avascular cornea, resulting in ocular surface diseases and even vision loss. Although great progress has been achieved, healing of severe ocular surface injury ...
