purpose: congenital corneal leukoma is rare with an incidence of 6/100000 and is one of the most important causes of amblyopia. here we report an unusual case of bilateral congenital elevated corneal leukoma. methods: we encountered a 13-day-old full term male newborn. ocular examination of both eyes revealed central elevated corneal leukomas with a narrow normal lucid interval to limbus. corne...

Report keratoconus in two patients with a long history of wrestling without any risk factor for corneal ectasia and reviewing the possible pathogenesis. To confirm suspicion of keratoconus, corneal topography was performed using scanning slit topography system and Orbscan. In two wrestlers with the complaint of visual loss in their eyes and IOP raising, corneal topography was performed and de...

PURPOSE To characterize dendritic cells (DC) in normal human corneal epithelium. METHODS Normal human donor corneal epithelium was examined by fluorescence microscopy with single and double staining for multiple markers. Morphologic studies were also performed by confocal microscopy. HLA-DRa, CD1c, and CD16 mRNA expression in the corneal epithelium was examined by RT-PCR. CD45+ cells were sep...

Keratosis follicularis spinulosa decalvans (KFSD) is a rare X linked disease which is characterised by follicular hyperkeratosis of the skin and corneal dystrophy. Seven male patients and six female carriers are described. Special attention has been paid to the dermatological and ophthalmic markers of KFSD in patients and carriers. The most prominent features present in the male patients were f...

Primary cilia are required for several signaling pathways, but their function in cellular morphogenesis is poorly understood. Here we show that emergence of an hexagonal cellular pattern during development of the corneal endothelium (CE), a monolayer of neural crest-derived cells that maintains corneal transparency, depends on a precise temporal control of assembly of primary cilia that subsequ...

In this study we show that murine and human neutrophils are capable of secreting IP-10 in response to communication from the HSV-1 infected cornea and that they do so in a time frame associated with the recruitment of CD8(+) T cells and CXCR3-expressing cells. Cellular markers were used to establish that neutrophil influx corresponded in time to peak IP-10 production, and cellular depletion con...

PURPOSE Ripasudil (Glanatec), a selective Rho-associated coiled coil-containing protein kinase (ROCK) inhibitor, was approved in Japan in September 2014 for the treatment of glaucoma and ocular hypertension. The purpose of this study was to investigate the effect of ripasudil eye drops on corneal endothelial morphology, as ROCK signaling is known to modulate the actin cytoskeleton. METHODS Mo...

PURPOSE The purpose of this study was to determine whether myofibroblast differentiation altered keratocyte crystallin protein concentration and increased cellular light scattering. METHODS Serum-free cultured rabbit corneal keratocytes and TGFβ (5 ng/mL) induced myofibroblasts were harvested and counted and protein/RNA extracted. Expression of myofibroblast and keratocyte markers was determi...

PURPOSE To determine the relative expression of cell cycle-association proteins in human corneal and limbal epithelium and corneal endothelium in situ, to correlate staining patterns of cell cycle-associated proteins with known proliferative status of corneal and limbal epithelial cells, and to determine the relative proliferative status of corneal endothelial cells in situ by comparing their s...
