Neurotrophic keratitis (also called neurotrophic keratopathy) (NTK) is a degenerative disease of the cornea, accompanied with neurogenic inflammation. It caused by sensitive innervation loss trigeminal nerve and characterized reduced sensitivity cornea retardation its healing process. NTC-causing damage to can occur at different levels-from nucleus terminals located in be ocular systemic diseas...

BACKGROUND: The Ostrich is an interesting subject concerninganimal evolution and morphology studies. It has been speculatedthat ostrich eyes would have distinct tissue structures and this hasnot been previously studied in detail. OBJECTIVES: The aim of thepresent study was to investigate the histology of the outer layer ofthe ostrich. METHODS: Ten mature ostriches were chosen from anostrich bre...

purpose : to develop a guideline for the treatment of incompletely removed histopathologically documented ocular surface neoplasia (ossn) with mitomycin c (mmc). materials & methods : through an interventional case series, 17 eyes of 17 patients presented with incompletely removed ossn were treated according to a protocol using 2-3 alternate 7-day courses of mmc 0.04%. clinical recurrence was r...

However, number authors have criticized on various grounds, including it has odd results, cannot do the work was meant to, and problematically conflicts with so-called common sense epistemology.

PURPOSE To evaluate the expression patterns of neurotrophic factors (NTFs) and their receptors in the human cornea with the intention of exploring the role of NTFs in maintaining corneal epithelial stem cells in the limbus. METHODS Fresh human corneoscleral tissues were prepared for frozen sections. Immunofluorescent staining was performed with primary antibodies against six members of three ...

The cornea is composed of 4 main layers: the epithelium, stroma, Descemet’s membrane, and the endothelium. The cornea is a highly innervated structure containing branches from the trigeminal nerve (CN V), which provides large nerve plexi that extend throughout the stroma and epithelium. The cornea is normally avascular, obtaining its nutrients from the tear film externally, and the aqueous humo...
