AIM: To evaluate the function of the microprobe dredging technology in the treatment of meibomian gland dysfunction(MGD)and to provide fast, efficient, economical and practical method of treatment for meibomian gland dysfunction(MGD).

METHODS:The 100μm diameter stainless steel wire was made as the microprobe with the total length of 3cm, which the needle was about 5mm and hand shank was about 2.5cm. Selected 140 cases with dry eyes of meibomian gland dysfunction(MGD), patients were divided into two groups and made them have comparability. Observation group(n=70)used microprobe to dredge meibomian gland pipe accompanied with drugs, hot compress and meibomian gland massage treatment. The control group(n=70)was given conventional drugs, hot compress and meibomian massage treatment. To compare the tear break-up time(BUT), efficient rate and the cure rate of the two groups after treatment of 1d, 1wk, 2wk, 1 mo, 2mo and 3mo.

RESULTS: BUT were significantly prolonged in observation group and control group after treatment, and the observation group improved more obviously; the efficient rate and cure rate of the observation group were significantly higher than that of the control group after 1d, 1wk, 2wk, 1mo, 2mo and 3mo treatment.

CONCLUSION:Using microprobe to unclog the meibomian gland tube can provide the fast and efficient, economical and practical treatment for meibomian gland dysfunction(MGD), which can be promoted in the clinical practice.
