A case of acquired posterior keratoconus is presented. As in developmental cases the vision was moderately reduced and the condition was not progressive. Posterior keratoconus is usually developmental in origin, but trauma has been implicated in some cases.

Abstract Today, corneal refraction, height, and thickness data, which are required in the diagnosis of keratoconus, can be obtained with tomography devices. Pentacam four map display presenting this data is one most basic options keratoconus. In article, an artificial intelligence‐based method using images proposed to distinguish keratoconus from healthy eyes. Axial/sagittal curvature, back ele...

PURPOSE Brittle cornea syndrome 1 (BCS1) is a rare recessive condition characterized by extreme thinning of the cornea and sclera, caused by mutations in ZNF469. Keratoconus is a relatively common disease characterized by progressive thinning and ectasia of the cornea. The etiology of keratoconus is complex and not yet understood, but rare ZNF469 variants have recently been associated with dise...

PURPOSE Keratoconus is characterized by the thinning of corneal stroma, resulting in reduced vision. The exact etiology of keratoconus (KC) is still unknown. The involvement of oxidative stress (OS) in this disease has been reported. However, the exact mechanism of OS in keratoconus is still unknown. Thus we planned this study to screen mitochondrial complex I genes for sequence changes in kera...

PURPOSE The purpose of the study was to determine molecular changes in selected epithelial proteins in human keratoconus (KC) corneas compared to normal corneas. METHODS Two-dimensional (2-D) gel electrophoretic profiles of epithelial cell proteins from normal and keratoconus corneas were compared, and the selected protein spots that showed either up- or downregulation were identified. The de...

Keratoconus is an evolving condition. The speed and severity of the course differs from patient to patient. We report clinical observation a 36-year-old with history severe atopy who presents neglected bilateral keratoconus. examination found sign Munson Rizzuti, corneal protrusion being more marked in left eye. Biomicroscopic revealed opacity central right eye thinning. In eye, there was strom...

Using immunofluorescence techniques, we analyzed the distribution of glycoproteins in normal and keratoconus corneas of humans. Laminin, bullous pemphigoid antigen, fibronectin, and fibrin/fibrinogen were all found in the epithelial basement membrane of normal corneas. Keratoconus corneas produced similar results, except that staining for fibrin/fibrinogen was weak. Fibrin/fibrinogen was absent...

Keratoconus associated with myelinated retinal nerve fibers is not frequent and the relationship between the two pathologies is difficult to explain, therefore studies and further investigation are required. The etiology of each condition may suggest the role of genetic factors. Follow-up is important to evaluate the progression of keratoconus and myelination. Here we describe the unusual coexi...

in the complexes formed as a consequence of heat treatment. BLG contains five Cys residues and KCN contains 2 Cys residues, and thus there is a large number of combinations of possible disulfide bondings. Reacting reduced KCN with DTNB (dithiobisnitrobenzoic acid) gives KCN molecules containing activated Cys groups. Reacting partially reduced BLG with these derivatives gave a range of products....

purpose: comparing the optical coherence tomography (oct) pachymetry patterns in keratoconus suspect and normal people methods: thirty-two keratoconus suspects and 36 healthy eyes were selected within the age range of 20-30 yrs. their pachymetry pattern was obtained through oct visante in the minimum thickness spot, upper and lower corneal difference (i-s), lower temporal, and upper nasal thick...
