Abstract:
Purpose:To analyze the correlation between the ocular surface staining score and indices of salivary gland scintigraphy in patientswith primary Sjögren's syndrome and dry eye symptoms, and to evaluate the diagnostic value of these indices.
Methods:The patients were 51 adults with primary Sjögren's syndrome or non-Sjögren's syndrome plus dry eye symptoms, whowere referred to our ophthalmology clinic for evaluation of the degree of dry eye at the Department of Rheumatology, from July2017 to April 2019. The Mann-Whitney U test and student’s t-test were used for analyzing the ocular surface staining score andquantitative indices of salivary gland scintigraphy, respectively, in the primary Sjögren's syndrome and non-Sjögren's syndromepatients. Spearman correlation was used to analyze the correlations of ocular surface staining score with salivary scintigraphyindices.
Results:The ocular surface staining score (p= 0.021), parotid gland excretion fraction (p= 0.022), and submandibular gland excretionfraction (pp= 0.045) were significantly different between the primary Sjögren's syndrome and non-Sjögren's syndromepatients. The submandibular gland uptake ratio (r = -0.369, p= 0.008) and submandibular excretion fraction (r = -0.359, p=0.010) were significantly negatively correlated with ocular surface staining scores.
Conclusions:The ocular surface staining score was identified as the gold standard for evaluating the degree of dry eye in primarySjögren's syndrome patients. If salivary gland dysfunction is identified by salivary gland scintigraphy, ocular surface stainingshould be performed to confirm the presence of ocular surface lesions, regardless of the presence of dry eye symptoms.
