Analysis of Clinical Characteristics of Immune-Related Dry Eye

Aim. To discuss the clinical characteristics of immune-related dry eye. Methods. Simple dry eye (SDE) group: we selected 224 patients of simple dry eye with no systemic lesions. Immune-related dry eye (IRDE) group: we selected 207 patients of dry eye complicated with immune system diseases, including 70 cases of Sjögren’s syndrome (SS), 72 cases of systemic lupus erythematosus (SLE), and 65 cases of rheumatoid arthritis (RA). The classification of all patients was performed. The difference between the two groups was compared, including age, gender, ocular surface fluorescein staining and inflammatory reaction, tear breakup time (TBUT), Shirmer I test, confocal microscopy scan, and dry eye grading. Results. Compared with the SDE group, the patients of IRDE group were younger (). The female patients were significantly more than the male ones (). Corneal staining counts and ocular surface inflammation were significantly increased (). TBUT and Shirmer I test shortened significantly (). Corneal nerve fibers were less, and the number of local lymphocyte was significant increased. The number of dry eye patients in the moderate or above IRDE group was significantly increased (). Conclusions. The dry eye symptom and sign and ocular surface inflammation of IRDE were significantly more severe than those of the SDE.
