“…MMP-8/TIMP-1 and MMP-9/TIMP-1 ratios were markedly elevated in both SJS and OCP groups (SJS>OCP) compared to controls. 74 Across all study groups, MMP-9 was strongly correlated with MMP-8 and myeloperoxidase levels, suggesting that neutrophils are the primary source of the tear MMP-9 in these conditions.…”

Dry eye and tear dysfunction are common ocular disorders that cause cornea barrier disruption resulting in a poorly lubricated and irregular cornea epithelium, eye irritation and blurred vision. Increased levels and activities of matrix metalloproteinases (MMPs), particularly MMP-9, have been detected in the tears and ocular surface epithelial and inflammatory cells in dry eye. MMPs have been found to participate in disruption of tight junctions in the apical cornea epithelium leading to their accelerated desquamation and barrier disruption. This review summarizes evidence showing the contribution of MMPs to dry eye pathogenesis and their roles as biomarkers and therapeutic targets. Keywords: matrix metalloproteinase, dry eye, keratitis sicca, cornea, barrier function, Sjögren syndrome Dry eye overviewDry eye and tear dysfunction are common ocular disorders that cause cornea barrier disruption resulting in a poorly lubricated and irregular cornea epithelium, eye irritation and blurred vision. It affects millions of people worldwide and is one of the most frequent conditions for which patients seek eye care.1 Aging and female sex are significant risk factors for dry eye which increases in prevalence around the fifth decade, with further increase every decade thereafter.2-13 Prevalence of dry eye varies from 2% to 50%, depending on the population studied and the diagnostic criteria for dry eye (symptom questionnaire vs. objective signs). [1][2][3]6,7,[9][10][11][14][15][16][17][18][19][20][21][22][23] There is scarce information about the natural history of dry eye, but there is a recognized disconnection between signs and symptoms; patients tend to be more symptomatic at early stages.24,25 Dry eye causes corneal irregularity [26][27][28] and decreases functional vision by altering contrast sensitivity [29][30][31] and, therefore, decreases quality of life with a significant burden on the individual as well as the society. 23,[32][33][34][35] A meta-analysis of 22 published studies showed increased odds ratio for depression and anxiety in patients with ocular Sjögren syndrome (SS). 36 There is increased evidence that dry eye is an inflammatory disease, and this review will focus on matrix metalloproteinases (MMPs) and their role in the pathogenesis of dry eye. Cornea barrier disruption is a feature of dry eyeAs the principal lens of the eye, the cornea has unique features to maintain its transparency and smooth surface that include a lack of blood vessels and a multilayered stratified, non-cornifying epithelium. The differentiated apical epithelial cells produce

This review is in two sections. The first section summarises 35 conditions, both common and infrequent, causing cicatrising conjunctivitis. Guidelines for making a diagnosis are given together with the use of diagnostic tests, including direct and indirect immunofluorescence, and their interpretation. The second section evaluates our knowledge of ocular mucous membrane pemphigoid, which is the commonest cause of cicatrizing conjunctivitis in most developed countries. The clinical characteristics, demographics, and clinical signs of the disease are described. This is followed by a review and re-evaluation of the pathogenesis of conjunctival inflammation in mucous membrane pemphigoid (MMP), resulting in a revised hypothesis of the autoimmune mechanisms causing inflammation in ocular MMP. The relationship between inflammation and scarring in MMP conjunctiva is described. Recent research, describing the role of aldehyde dehydrogenase (ALDH) and retinoic acid (RA) in both the initiation and perpetuation of profibrotic activity in MMP conjunctival fibroblasts is summarised and the potential for antifibrotic therapy, using ALDH inhibition, is discussed. The importance of the management of the ocular surface in MMP is briefly summarised. This is followed with the rationale for the use of systemic immunomodulatory therapy, currently the standard of care for patients with active ocular MMP. The evidence for the use of these drugs is summarised and guidelines given for their use. Finally, the areas for research and innovation in the next decade are reviewed including the need for better diagnostics, markers of disease activity, and the potential for biological and topical therapies for both inflammation and scarring.
