title: Ophthalmological tests in patients with keratoconjunctivitis sicca with and without association of primary Sjögren's syndrome.
abstract: We compared clinical, laboratory and histological tests in patients with keratoconjuctivities sicca with and without association of primary Sjögren's syndrome. Rosa bengal staining, osmolarity and impression cytology had high specificity and sensitivity for a correct diagnosis of keratoconjunctivitis sicca with and without primary Sjögren's syndrome. Schirmer and breakup time (BUT) tests were not quite as specific or sensitive. Impression cytology was the only ocular test that showed significant differences between the two pathological groups.
