Purpose : To evaluate the causes related to dry eye in the elderly Koreans.
Methods : Dry eyes were screened using the SPEED questionnaire for the 36 elderly subjects (72 eyes, 17 males, 19 females, average age 62.11±4.84 years old). The amount of tear was evaluated by OCCUTUBE, and the stability of the tear film was evaluated by the tear film break-up time test. Tear lipid layer thickness (LLT), blinking counts and meibomian gland damage were measured by LIPIVIEW II® and analyzed with the Image J® program.
Results : In the dry eyes, the score of SPEED questionnaire was 10.11±4.91 points, and the measured score of OCCUTUBE and the TBUT was 3.38±1.15 mm, 4.49±1.31 sec, respectively, which was not significantly different from those of the normal eyes. However, LLT (80.36±20.78 nm) was significantly thicker than that of the normal eyes (p=0.021). Meibomian gland (MG) damage grade (MG dropout, MG curling and, Gland thickness) was 1.17±0.70, 0.47±0.61 and, 0.61±0.60, respectively, which was more damaged than those of the normal eyes. LLT was positively correlated with the SPEED score (p<0.009), and negatively correlated with MG loss. And the MG score was correlated with gland thickness and MG loss (p<0.050).
Conclusion : In the elderly dry eyes screened with the SPEED questionnaire, the dry eye symptoms could be associated with LLT, and LLT is thought to be related to hypersecretory MG dysfunction.
