AIM: To probe into the treatment effects of P50 EX-PRESS drainage nail combined with biological amniotic membrane implantation in primary open angle glaucoma(POAG).METHODS: Totally 96 cases of 96 eyes with POAG and who treated from March 2013 to January 2019 were selected as the research objects, and the patients were divided into the observation group and the control group by the random number table method, with 48 cases in each group. The control group was implanted with P50 EX-PRESS drainage nail only, while the observation group were treated with biological amniotic membrane implantation on the basis of the control group. Then, the changes of intraocular pressure, retinal nerve fiber thickness(RNFLT), complications and success rate of operation before operation and after the operation for 7d, 1mo and 3mo of two groups of patients were observed.RESULTS: The proportion of functional filtering blebs after operation for 3mo in the observation group was significantly higher than that in the control group(PP>0.05). The intraocular pressure and RNFLT after operation for 7d, 1mo and 3mo in the observation group were significantly lower than those in the control group(PP>0.05). The success rates of operation in observation group and control group were 96% and 75% respectively(PCONCLUSION:The application of P50 EX-PRESS drainage nail combined with biological amniotic membrane implantation for POAG, which the clinical effects are satisfactory, and which can improve the condition of filtering blebs, reduce intraocular pressure and RNFLT, thus it has good safety and high success rate. |
