Abstract:
Objective To analyze the correlation between the dry eye symptom and signs in middle-aged and aged people by Lipiview(R) ocular surface interferometry.Methods A total of 170 eyes from 85 middle-aged and aged people (55-80 years old) were examined with Standard Patient Evaluaion of Eye Dryness(SPEED) questionnaire and Lipiview(R) ocular surface interferometry,meanwhile obtaining the consent of the subjects.Then the correlation between the symptom and Lipid Layer Thinckness (LLT) and partial blink rate were analyzed.Results SPEED questionnaire score was 6.13 ±4.60.LLT was(74.88 ± 21.16) nm.LLT variability was 4.47 ± 3.40.The partial blink rate was 0.62 ± 0.36.The Spearman correlation analysis indicated that the nega-tive correlation was shown between the SPEED questionnaire score and LLT (r =-0.823,P =0.000),SPEED questionnaire score and LLT variability(r =-0.268,P =0.018).The positive correlation were found between LLT and Std.Dev of LLT (r =0.339,P =0.030).However,the results of the SPEED score were uncorrelated with partial blink rate (P ＞ 0.05).Conclusion The results from this study demonstrate that correlation among symptom,LLT and LLT variability,but poor correlation between symptom and partial blink rate.
