AIM: To analysis the clinical effect of lacrimal plug treated refractory dry eye video terminal.

METHODS:A total of 80 patients with video terminals resistant dry eyes were selected in our hospital between Mar.2013 to Mar.2015. A prospective randomized controlled study used the software SAS9.2. All the patients were randomly divided into control group and observation group, 40 patients in each group. The control group treated with drops of ophthalmic, observation group treated with lacrimal duct embolus. A course included 30d, a total of 3 courses were in the treatment. The two groups before and after treatment in patients with tear secretion test and integral-rupture time and symptoms were observed and compared.

RESULTS: Observation group number of therapy effective and efficient eye were significantly larger than control group, and number of invalid eyes was less than that of control group, the total efficiency was higher than control group, the difference was statistically significant(P<0.05). Before treatment, the tear secretion test and tear film break-up time in two groups had no significant difference, after treatment, the above indexes of the two groups all increased, while observation group increased more significantly(P<0.05). Before treatment, scores of dry senses, foreign body sensation, visual fatigue and the total scores of symptoms in the two groups had no significant difference. After treatment, the above indexes of the two groups all decreased and the observation group decreased more significantly(P<0.05).

CONCLUSION:Lacrimal plug has good treatment effect on the video terminal refractory dry eye, which can significantly improve the patient's clinical symptoms, with good clinical application value.
