| Objective:To observe the therapeutic effects and changes of TCM Syndromes on hi gh myopia after the surgery of posterior scleral reinforcement.Methods:Divided into two groups:surgery group and control groupThe surgery group:Patients with high myopia after the surgery of pos terior scleral reinforcement, who were performed at the First Affiliated Hospital of Guangzhou University of Chinese Medicine from 2006 to 2013.21 cases(40 eyes samples)The control group:Patients with high myopia, after Mydriasis Test & Optometry, but no posterior scleral reinforcement surgery and experienced outpatient service at the First Affiliated Hospital of Guangzhou Univers ity of Chinese Medicine for more than 2 years, from 2009 to 2014.24 case s(44 eyes samples)Content analysis:(1) Contrast between surgery group and control group on diopter stab ility rate and average annual growth(2) How Surgery group patients’ Preoperative age and diopter related to the therapeutic effect on 7-14 days and 1-8 years after surgery. The p ostoperative curative effect observation index include:diopter, axial le ngth, corrected visual acuity, central subfield thickness of retinal macula (macula fovea diameter 1mm)(3) The comparison of the corrected visual acuity, the axial length, diopter and the central subfield thickness of retinal macula before and a fter the operation.(4) The changes of TCM syndromes before and after.Results:1.Diopter:The Diopter stability rate of surgery group is 77.5% while control group 34.09%; The average annual growth of Diopter in the operat ion group is -0.19±0.36 D, and control group -0.61±0.26D. On contrast, t here’s a big difference between surgery group and control group In Statis tics (t=5.798, P=0.000<0.05).2. After chi-square test, preoperative age and Diopter were independent from the corrected visual acuity, Diopter, axis length and the central sub field thickness of retinal macula in the next 7-14 days and 1-8 years aft er operation (P>0.05)3. The comparison of operation group before and after surgeryCorrected visual acuity contrasting before and after sugery in 7-14 d ays:t=-1.599 p=0.118>0.05, no significant difference in Statistics.Corrected visual acuity contrasting before and after sugery in 1-8 ye ars:t=-2.767 p=0.009<0.05, significant difference in Statistics, correc ted visual acuity improved in 1-8 years after surgery.Diopter contrasting before and after surgery in 7-14 days:t=-0.251 p =0.803>0.05, no significant difference in Statistics.Diopter contrasting before and after surgery in 1-8 years:t=2.908 p= 0.006<0.05, significant difference in Statistics, the latter better than before.Axial length contrasting before and after surgery in 1-8 years:t=0.8 94 p=0.000<0.05, significant in Statistics. During the 1-8 years after o peration, Axial length extended, Annual Average growth is 0.24±0.28mm, F or instance, in 40 samples, Annual Average growth<0.3mm, Accounted for 31, Stability rate is 77.5%Central subfield thickness of retinal macula contrasting before and a fter surgery in 1-8 years:t=1.012 p=0.318>0.05, no difference in Statis tics.4. TCM Syndromes changes before and after:Before:Heart-Yang Deficiency (54%) and Liver and kidney deficiency (3 6%)After:Heart-Yang Deficiency (38%) and Liver and kidney deficiency (62 %)Conclusions:1. Posterior scleral reinforcement can delay the development of diopte r and ocular axis. In the next 1-8 years after surgery, corrected visual acuity is improving and the central subfield thickness of retinal macula area keep in stable.2. Preoperative age and Diopter are independent from the changes of c orrected visual acuity, Diopter, axis length and the central subfield thick ness of retinal macula in the next 7-14 days and 1-8 years after operatio n.3. With time going, the TCM syndrome types of high myopia patients ar ise the tendency, more and more Heart-Yang deficiency changing into the Liver and kidney deficiency. |
