Confirmatory tests for the dry eye of Sjögren's syndrome. 1986

I A Mackie, and D V Seal

The diagnosis of moderate degrees of tear depletion is difficult using conventional tests such as the Schirmer test, clinical evidence and even a confirmatory test such as the lysozyme test. We have refined the lysozyme test using quantitative techniques and calibrated standards. We found this satisfactory on a population basis, but not on an individual basis. We developed an ELISA test for assaying five tear proteins 'lysozyme, lactoferrin, ceruloplasmin, IgA and IgG' which gives a much more accurate assessment of dryness on an individual patient level.

UI	MeSH Term	Description	Entries
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D012859	Sjogren's Syndrome	Chronic inflammatory and autoimmune disease in which the salivary and lacrimal glands undergo progressive destruction by lymphocytes and plasma cells resulting in decreased production of saliva and tears. The primary form, often called sicca syndrome, involves both KERATOCONJUNCTIVITIS SICCA and XEROSTOMIA. The secondary form includes, in addition, the presence of a connective tissue disease, usually rheumatoid arthritis.

D014985	Xerophthalmia	Dryness of the eye surfaces caused by deficiency of tears or conjunctival secretions. It may be associated with vitamin A deficiency, trauma, or any condition in which the eyelids do not close completely.	Xerophthalmias
