The cornea is unique because of its complete avascularity. Corneal neovascularization (CNV) can result from a variety of etiologies including contact lens wear; corneal infections; and ocular surface diseases due to inflammation, chemical injury, and limbal stem cell deficiency. Management is focused primarily on the etiology and pathophysiology causing the CNV and involves medical and surgical options. Because inflammation is a key factor in the pathophysiology of CNV, corticosteroids and other anti-inflammatory medications remain the mainstay of treatment...

PURPOSE: Current scales for assessment of bulbar conjunctival redness have limitations for evaluating digital images. We developed a scale suited for evaluating digital images and compared it to the Validated Bulbar Redness (VBR) scale. METHODS: From a digital image database of 4889 color corrected bulbar conjunctival images, we identified 20 images with varied degrees of redness. These images, ten each of nasal and temporal views, constitute the Digital Bulbar Redness (DBR) scale...

Di Chen, Afsun Sahin, Wendy R Kam, Yang Liu, Raheleh Rahimi Darabad, David A Sullivan
PURPOSE: Lipopolysaccharide (LPS), a bacterial endotoxin, is known to stimulate leuokotriene B4 (LTB4) secretion by human corneal (HCECs), conjunctival (HConjECs) and meibomian gland (HMGECs) epithelial cells. We hypothesize that this LTB4 effect represents an overall induction of proinflammatory gene expression in these cells. Our objective was to test this hypothesis. METHODS: Immortalized HCECs, HConjECs and HMGECs were cultured in the presence or absence of LPS (15 μg/ml) and ligand binding protein (LBP; 150 ng/ml)...

PURPOSE: Lax eyelid syndrome (LES) is defined as the association of distensible "floppy" eyelids and chronic papillary conjunctivitis. LES is also found in patients with obstructive sleep apnea (OSA) who have systemic elevation of inflammatory markers, including matrix metalloproteinases (MMP). Locally elevated MMP levels have also been demonstrated co-localized with elastin loss in eyelids of patients with LES, accounting for their "floppiness." The purpose of this study was to investigate tear film MMP levels and determine their association with eyelid laxity and OSA...

#19
REVIEW
Kwaku A Osei, Champion Deivanayagam, Jason J Nichols
Glycoprotein 340 (Gp340) is an innate immune receptor with well-defined roles in mucosal tissues. It is a normal component of mucosal fluids such as tears, breast milk, and saliva, and it is expressed in tissues such as the vagina, gastrointestinal tract, oral cavity, lung alveoli, and pancreas. In the eye, it is expressed in the lacrimal gland, cornea, conjunctiva, and retina. Investigations of the protein in wet-surfaced epithelia of the body show that the effects of Gp340 can be beneficial or harmful depending on the conformation in which it exists...
