[Abstract]:objective
1. to observe the effect of autologous lens anterior capsule as an implant in the treatment of rabbit eye phacoemulsification combined with trabeculectomy.
2. compare the clinical effect of the anterior capsule of autologous lens and mitomycin C in the combined operation of glaucoma and cataract, and evaluate the safety and effectiveness of the anterior lens capsule.
Method
1. animal experiments: 20 New Zealand white rabbits were treated with phacoemulsification combined with trabeculectomy. They were randomly divided into two groups, 10 rabbits in each group (20 eyes) and first groups: 1 eyes were randomly selected to do phacoemulsification and trabeculectomy (Trab group), the other 1 eyes were excised by phacoemulsification and assisted with the anterior capsule (ALC group); second Group: 1 eyes were randomly selected to do phacoemulsification and trabeculectomy combined with mitomycin C (MMC group); the other 1 eyes were treated with phacoemulsification and assisted with the anterior capsule membrane. On day 3,7,14,21,28, the anterior segment reaction, the morphology and function of filter bubble, the intraocular pressure, and the 5 of the three different surgical procedures were compared. At each time point, 1 rabbits were randomly executed in two groups to make pathological sections, and the filter passages were observed under light microscope.
2. clinical study: 60 cases (60 eyes) of hospitalized patients with glaucoma diagnosed in Ophthalmological Center of Tianjin Medical University from May 2010 to March 2011 were selected with two incision phacoemulsification, posterior chamber foldable intraocular lens implantation and trabeculectomy, and were randomly divided into group ALC and group MMC, ALC The anterior capsule of autologous lens was implanted under the scleral flap in 29 cases (29 eyes), and 31 cases (31 eyes) in group MMC were treated with mitomycin. The intraocular pressure of the two groups, the best corrected visual acuity, the form of filtering bleb and the postoperative complications were observed in the group of 31 (31 eyes), and the observation results were analyzed and compared. Data was processed with SPSS16.0 statistical software, and P0.05 as the difference was statistically significant.
Result
1. animal experiments: (1) anterior segment reaction: there was no significant difference in conjunctival hyperemia (x 2=0.784,0.232, P value 0.05) on day 1,5 after 3 surgical operations, and there was no statistically significant difference in corneal opacity (x 2=1.200,3.442, P value 0.05), and there was no statistical significance (x 2=3.599,3.200,3.388,2.133, P value 0) before the operation (0). .05), all eyes did not find the stimulation of the capsule to the rabbit eye; (2) the filter bubble situation: twenty-first days after the operation, the proportion of the 3 functional filtration blebs was 14.3% (1/7), 92.9% (12/14), 85.7% (6/7), the difference was statistically significant (x 2=13.077, P0.05), combined with the proportional value, the functional filter bubbles of the ALC group and MMC group could be considered. Number more than Trab group, other observation time between the 3 groups had no statistical significance; (3) intraocular pressure: 3 kinds of postoperative intraocular pressure decreased early, then gradually increased, postoperative 14,21 day intraocular pressure difference was statistically significant (x 2=14.377,10.279, P value is 0.05), the other observation time between the 3 groups had no statistical significance; (4) histopathology: 7 after the operation 7 In group Trab, 1 eyes were close to the proximal part of the filter, ALC and MMC were open, and the ALC group showed that the membrane structure was complete, the edge was clear, and the boundary was clear, and no inflammatory cells were intruded. The Trab group was completely blocked by scar tissue on the 28 day after the operation, and the distal end of the MMC group was closed, the proximal part of the filter was open, ALC The filtering passages were completely open, and the edges of the membranes were blunt and there was no lymphocytic infiltration.
2. clinical study: (1) intraocular pressure: at 1 years after operation, intraocular pressure in group ALC decreased from (22.28 + 10.81mmHg) to (12.24 + 2.91mmHg), and the difference was statistically significant (t=4.851, P0.05), and in group MMC, intraocular pressure dropped from (26.50 + 12.69mmHg) to (11.15 + 2.87mmHg), and the difference was statistically significant (t=6.701, P0.05). The degree of IOP decline at each time point between groups was not unified. Study difference; (2) best corrected visual acuity: 1 years after operation, the visual acuity of the two groups was higher than before the operation, the difference was statistically significant (tALc=-5.294, P0.05; tMMc=-4.027, P0.05), and there was no statistical difference between the two groups (t=-0.022, P0.05); (3) the form of filtering bleb: 1 years after the operation, ALC group I, type II filter bubbles were 4 eyes and 21 eyes respectively, that is, Functional filtration blebs accounted for 86.2% (25/29) and type III filter bubbles in 4 eyes; group I and type II filter bubbles were 5 eyes, 24 eyes, 93.5% (29/31), 2 eyes of type III filter bubbles, two groups without type IV filter bubbles, and two groups of filter bubbles in two groups (x 2=0.912, P0.05), and (4) the success rate of operation and the use of anti glaucoma drugs (4). 1 years after operation, the success rate of group ALC was 86.2% (25/29) and 93.5% (29/31) in group MMC. There was no statistical difference between the two groups (2=0.897, P0.05). Before operation, there were 2.45 kinds of anti glaucoma drugs in group ALC and 2.61 in MMC group; 1 years after the operation, the ALC group decreased to 0.14, and the MMC group was 0.06. The difference was statistically significant before and after the operation. TALc=13.970, tMMC=14.772, P0.05); (5) complications: two groups of postoperative complications were subsided or remission within 2 weeks after operation, and group ALC had no serious rejection; (6) the average visual field defect value of the patients in the 1 year after operation, and the average pattern standard deviation was not statistically different from that before the operation, that is, the postoperative visual field was maintained. Stability; (7) ultrasound biomicroscopy: two groups of patients showed clear filtration space at 3 months after 3 months of operation, and the inside and outside of the filter were unobstructed, while the anterior capsule of the scleral flap was strongly echoed by the scleral flap, which was the anterior capsule of the lens.
conclusion
1. animal experiments: there was no significant difference between the anterior capsule and mitomycin in the anterior capsule reaction and the effect of the intraocular pressure in the phacoemulsification of the trabeculectomy, but the histopathological results showed that the time of the implantation of the anterior capsule to maintain the filter was longer than that of mitomycin. Both of them were obviously superior to the simple trabeculae. The effect of lowering intraocular pressure and scar degree of filtering passage after resection were observed.
2. clinical study: the application of the anterior capsule of the lens to the combined operation of glaucoma and cataract can effectively prevent the scarring of filter bubbles, control the intraocular pressure, improve the vision and stabilize the field of vision, which is quite effective with the traditional application of mitomycin C, and the method is safe and effective.
