Innate Immunity of the Ocular Surface and Ocular Surface Inflammatory Disorders
Cornea, 2008Ocular surface epithelial cells selectively respond to microbial components and induce limited inflammation, whereas immune competent cells such as macrophages can recognize various microbial components through Toll-like receptors (TLRs), induce inflammation, and, thereby, exclude microbes.

Ocular Surface Abnormalities in Aniridia
American Journal of Ophthalmology, 1995The purpose of this study was to examine ocular surface abnormalities in aniridia.We prospectively studied the ocular surface in nine consecutive patients (18 eyes) with virtually total aniridia. Of the 18 eyes, two eyes (two patients) were excluded from the study because severe surgical damage was likely to be the main cause of their corneal ...

Mucins and Ocular Surface Disease
2002The ocular surface epithelium is covered by the tear film that consists of three layers: the lipid, aqueous, and mucus layers. The mucus layer is composed primarily of mucin proteins secreted by goblet cells. In addition to goblet cells of the ocular surface epithelium, the corneal and conjunctival epithelia also produces mucin.

The Effects of LASIK on the Ocular Surface
The Ocular Surface, 2004Laser in situ keratomileusis (LASIK) can affect corneal sensation, aqueous tear production, wound healing, and the incidence of corneal erosions. Virtually all patients experience dry eye at least transiently after LASIK. Because intact corneal sensation drives tear production, denervation associated with the LASIK procedure is the most significant ...

Innate Defense of the Ocular Surface
Eye & Contact Lens: Science & Clinical Practice, 2003The mucosal surface of the eye interfaces with the environment and can detect the presence of pathogens and irritants. The mucosal cells respond by up-regulating genes whose products either directly attack the contaminant or recruit leukocytes through the release of cytokines.

Management of ocular surface exposure
British Journal of Ophthalmology, 2012Appropriate management of ocular surface exposure depends on understanding the pathogenesis in terms of the adnexal tissues, epithelial surfaces, motor and sensory innervation, tear film and sometimes the treatment. A primary aim of the oculoplastic surgeon is to protect the ocular surface and preserve vision.

Ocular surface system integrity
Vestnik oftal'mologii, 2015The interplay of different structures belonging to either the anterior segment of the eye or its accessory visual apparatus, which all share common embryological, anatomical, functional, and physiological features, is discussed. Explanation of such terms, as ocular surface, lacrimal functional unit, and ocular surface system, is provided.

Evaporation from the ocular surface
Experimental Eye Research, 2004Evaporation from the ocular surface is dramatically reduced by the lipid layer which covers it. With this layer intact, evaporation represents a small loss of water for which the lacrimal gland easily compensates. When tear production is compromised evaporation becomes important, especially since evaporation in almost all ocular surface disease states ...

The Ocular Surface and Its Symbolism
The Ocular Surface, 2007©2007 Ethis Communications, Inc. The Ocular Surface ISSN: 1542-0124. Murube J. The ocular surface and its symbolism. 2007;5(1):6–12. ny picture—of a bee, a flower, an eye—is a very simple symbolic representation of the visual perception of a much more complex entity.

Role of vitamin A on the ocular surface
Experimental Eye ResearchVitamin A is an essential fat-soluble vitamin that cannot be endogenously synthesized by the human body. Retinoic acid (RA) is the biologically active form of vitamin A. Utilizing both nuclear and non-nuclear receptor-mediated pathways, RA plays a crucial role in regulating various biological processes, including apoptosis, differentiation, and anti ...
