Application of the microprobe dredging operation in the treatment of the meibomian gland dysfunction (MGD) / 国际眼科杂志(Guoji Yanke Zazhi)

AlM: 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. CONCLUSlON: 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.

The measurement of anterior chamber depth and axial length with the IOLMaster compared with contact ultrasonic axial scan / 国际眼科杂志(Guoji Yanke Zazhi)

· AIM: To compare the measurement of anterior chamber depth (ACD) and axial length (AL) by IOLMaster and contact ultrasonic (US) axial scan (A-scan).· METHODS: Measurements of ACD and AL were prospectively obtained in 137 eyes of 121 subjects with the IOLMaster compared with measurements with the US.· RESULTS: There was an excellent correlation between IOLMaster and US measurements for the ACD (r=0.823;P＜0.001) and AL (r=0.996;P＜0.001). The mean values of the parameters measured by IOLMaster and US were,respectively, as follows: ACD, 2.94±0.49mm, 2.58±0.51mm;AL, 24.37±3.04mm, 23.81±2.83mm. The mean differences of ACD and AL values between IOLMaster and US measurements were 0.36 ±0.30mm, 0.56 ±0.34 mm respectively, and they proved to be statistically significant (P＜0.001), With the 95%limits of agreement (LoA) from -0.08mm to +0.38mm for ACD and from -0.09mm to +0.69mm for AL.· CONCLUSION: As noncontact biometry, IOLMaster provides accurate values. A high degree of agreement between US and IOLMaster was noted. It not only has the advantage of performing noncontact examinations, but also produces various additional data simultaneously and may thus obviate the need for multiple examinations. Further studies are needed to assess the interchangeability of measurements in clinical practice.
