Vision loss due to corneal injuries or diseases can be treated by transplantation of human corneal grafts (keratoplasty). However, quality assurance in retrieving and cultivating the tissue transplants is confined to visual and microbiological testing. To identify previous refractive surgery or morphological alterations, an automatic, noncontact, sterile screening procedure is required. Twenty-...

For banks and financial institutions, credit risk had been an essential factor that needed to be managed well. Credit risk was the possibility that a borrower of counter party would fail to meet its obligations in accordance with agreed terms. Credit risk; therefore arise from the bank’s dealings with or lending to corporate, individuals, and other banks or financial institutions.  Credit risk...

deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...

The term “neuromarketing” suggests a combination of marketing research and brain research. Within marketing research, objective assessment of TV commercials is performed by use of EyeTracking devices. Brain research has been dominated by NMRI technologies during the last years. However, information content and time resolution are much better when monitoring electric activity by spectral analysi...

PURPOSE To assess the ability of trabecular micro-bypass stents to improve aqueous humor outflow (AHO) in regions initially devoid of AHO as assessed by aqueous angiography. METHODS Enucleated human eyes (14 total from 7 males and 3 females [ages 52-84]) were obtained from an eye bank within 48 hours of death. Eyes were oriented by inferior oblique insertion, and aqueous angiography was perfo...

Saccadic eye movements (SEMs) are the primary means of gating visual information in primates and strongly influence visual perception. The active exploration of the visual environment ("active vision") via SEMs produces suppression during saccades and enhancement afterward (i.e., during fixation) in occipital visual areas. In lateral temporal lobe visual areas, the influence, if any, of eye mov...

This study examined the effects of anterior arcuate and dorsomedial frontal cortex lesions on the execution of saccadic eye movements made to paired and multiple targets in rhesus monkeys. Identical paired targets were presented with various temporal asynchronies to determine the temporal offset required to yield equal probability choices to either target. In the intact animal equal probability...

AIMS To determine the epithelial proliferative capacity of organ cultured limbal tissue and correlate this with various donor and eye banking factors. METHODS 24 corneoscleral limbal (CSL) rims left over from penetrating keratoplasty were split in half and set up as in vitro explant cultures. Corneal epithelial proliferative potential (CEPP) was assessed by the number of "cycles" of growth ac...

PURPOSE To unravel the molecular genetic background in families with congenital cataract in association with microcornea (CCMC, OMIM 116150). METHODS CCMC families were recruited from a national database on hereditary eye diseases; DNA was procured from a national gene bank on hereditary eye diseases and by blood sampling from one large family. Genomewide linkage analysis, fine mapping, and d...

AIM To study the value of polymerase chain reaction (PCR) analysis, to detect viral DNA in recipient corneal buttons taken at the time of penetrating keratoplasty (PKP) in patients with an initial diagnosis of herpetic stromal keratitis (HSK). Since HSK has a tendency to recur, an accurate diagnosis of previous HSK could be the reason to start antiviral treatment immediately, thereby possibly d...
