[A comparative study of efficacy for treating conjunctivochalasis with positioning and quantified patch].
OBJECTIVE
To investigate the efficacy for treating conjunctivochalasis with conjunctival positioning and quantified patch.


METHODS
It was a case-control study. A case-control study of 30 patients from the First Hospital of Jiaxing from 2007 to 2008 with binocular conjunctivochalasis. Every patient was treated one eye with simple logadectomy while the other eye with positioning and quantified logadectomy randomly. Subjective and objective evaluations were taken on the 1st, 3rd and 6th months post-operation. Subjective evaluations include effective rate and cure rate. Objective evaluations include slit-lamp biomicroscope morphological variety, tear meniscus height, break-up time (BUT), Schirmer I test (SIT), fluorescein stain test (Fl), the first fluorescein stain. Cure rate and efficacy rate were compared in two groups with chi-square test.


RESULTS
Subjective evaluations were on the 1st month post-operation. There were 5 eyes (16.7%) curing, 13 eyes (43.3%) improved, 12 eyes (40.0%) ineffective in simply logadectomy group; While there were 12 eyes (40.0%) curing, 16 eyes (53.3%) improved, 2 eyes (6.7%) ineffective in the positioning and quantified logadectomy group. The effective rate (chi2=9.317, P<0.01) and cure rate(chi2=4.022, P<0.05)had statistic significance. Effective rate in simply logadectomy group was increasing gradually on the 3rd and 6th month post-operation while effective rate in positioning and quantified logadectomy group was stable. But the effective rate in this group was still higher than the simple logadectomy group. To objectively evaluate the cure rate on the 1st month post-operation: slit-lamp biomicroscope morphological variety: there were 10 eyes turn to normal in simply logadectomy group while 29 eyes (chi2=26.447, P<0.01) in the positioning and quantified logadectomy group. Tear meniscus height: there were 18 eyes turn to normal in simply logadectomy group while 30 eyes (chi2=15.000, P<0.01) in the positioning and quantified logadectomy group. BUT: There were 12 eyes turn to normal in simply logadectomy group while 28 eyes (chi2=19.200, P<0.01) in the positioning and quantified logadectomy group. SIT: there were 18 eyes turn to normal in simply logadectomy group while 25 eyes (chi2=4.022, P<0.05) in the positioning and quantified logadectomy group. Fl: there were 20 eyes turn to normal in simply logadectomy group while 28 eyes (chi2=6.667, P<0.05) in the positioning and quantified logadectomy group. The first fluorescein stain: there were 12 eyes turn to normal in simply logadectomy group while 24 eyes (chi2=10.000, P<0.01) in the positioning and quantified logadectomy group. The difference had statistic significance. On the 3rd month post-operation: SIT: there were 18 eyes turn to normal in simply logadectomy group while 19 eyes (chi2=0.071, P>0.05) in the positioning and quantified logadectomy group, without statistic significance. All the other objective evaluations indicatrix had statistic significance. On the 6th month post-operation: SIT: there were 20 eyes turn to normal in simply logadectomy group while 21 eyes (chi2=0.077, P>0.05) in the positioning and quantified logadectomy group, without statistic significance. Fl: there were 23 eyes turn to normal in simply logadectomy group while 28 eyes (chi2=3.268, P>0.05) in the positioning and quantified logadectomy group, without statistic significance. All the other objective evaluations indicatrix had statistic significance.


CONCLUSIONS
Positioning and quantified patch resection method not only makes it easier and safer for treating the conjunctivochalasis, but also reduces the complications and creates good result for patients in early period.
