We analyze the information that can be retrieved from tracking parameters produced by an innovative wearable eye tracker. The latter is based on a permanent-magnet marked corneal lens and array of magnetoresistive detectors measure magnetostatic field in several positions proximity. demonstrate that, despite missing due to axial symmetry measured field, physiological constraints or measurement ...

tears have antimicrobial, nourishing, mechanical, and optical properties and contain components such as growth factors, fibronectin and vitamins to support proliferation, migration and differentiation of corneal and conjunctival epithelial cells. lack of these epitheliotrophic factors, as in dry eye, can result in severe ocular surface disorders such as persistent epithelial defects. recently, ...

Corneal endothelium is formed of 1 layer of mitochondria-rich cubic cells whose main role is to maintain corneal transparency. Corneal endothelial disorders represent group of both inherited and noninherited and may affect proper vision.A 36-year-old male patient with suspicion of corneal endothelial dystrophy underwent visual acuity, intraocular pressure, the basic slit-lamp examination, anter...

With the rapid development of computer science and technologies in recent years, there has been dramatic advance in anterior segment imaging. As we have mentioned in the call for papers for this special issue, manuscripts are covering the topics of anterior segment imaging techniques including anterior segment optical coherence tomography (OCT), specular microscopy, corneal topography, confocal...

Keratocytes are fibroblast-like cells that maintain the optical clarity and the overall health of the cornea. The ability to measure precisely their density and spatial distribution in the cornea is important for the understanding of corneal healing processes and the diagnostics of some corneal disorders. A novel computerized approach to detection and counting of keratocyte cells from ultra hig...

Pterygium is characterized by the thickening of the bulbar conjunctiva and the invasion of the cornea from the sclerocorneal limbus to the central portion of the cornea. Pterygium produces corneal deformation, which extends toward the central portion of the cornea. The visual disorders depend on the corneal extent. The treatment goal is the removal of the corneal and conjunctival portion of the...
