BACKGROUND The sclera maintains and protects the eye ball, which receives visual inputs. Although the sclera does not contribute significantly to visual perception, scleral diseases such as refractory scleritis, scleral perforation and pathological myopia are considered incurable or difficult to cure. The aim of this study is to identify characteristics of the human sclera as one of the connect...

Developments in the surgery of retinal detachment since the time of Gonin have led from simple to more complicated methods which are not always more effective. Among the simple methods is the cerclage operation, developed by Arruga, in which a string of Supramid thread is sewn around the eyeball on the sclera and a sharp buckle is created, thus diminishing the volume of the eye and separating t...

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...

The vein structure is stable over time and can be manipulated for identifying human. The sclera portion of the human eye has blood vessel pattern which is unique for each human being. So, the sclera vein pattern can be used for a useful biometric feature. A few research works has been done over finger vein pattern recognition. Finger vein is an important biometric technique for personal identif...

PURPOSE To better understand the role of lumican (corneal keratan sulfate proteoglycan) in the scleral extracellular matrix, collagen fibril size, shape, and organization were evaluated in the sclera of wild-type mice and in mice homozygous or heterozygous for a null mutation in the lumican gene. METHODS. Anterior and posterior sclera from 6-month-old wild-type (lum+/lum+) and lumican-deficient...

Hydroxyproline (Hyp) concentrations (total, free, peptide-bound and protein-bound) in camel eye tissues were determined. Total Hyp concentration was highest in iris, followed by ciliary body, sclera, cornea, lens and retina; the difference between total Hyp concentration of iris and sclera (P < 0.05) and cornea, lens and retina (P < 0.001) was statistically significant. Cornea had the highest c...

PURPOSE This study was designed to examine the occurrence of natural cell death in the periocular mesenchyme of mouse embryos. METHODS Vital staining with LysoTracker Red and Nile blue sulfate as well as terminal nick end labeling (TUNEL) were utilized to identify apoptotic cell death in whole and histologicaly sectioned gestational day 10.5 to 14 mouse embryos. Laser scanning confocal micros...
