| Summary: | AIM: To compare effects of combined glaucoma-cataract surgery on pseudoexfoliation glaucoma(PXG)and primary open angle glaucoma(POAG).<p>METHODS: This was a retrospective case-control study conducted the hospitalized patients at department of glaucoma from January 2015 to January 2018. The PXG group included 40 eyes of 38 cases, with 46 eyes of 36 cases on POAG group, which were matched for baseline data. Visual acuity, intraocular pressure(IOP), number of anti-glaucoma medications used and occurrence of complications were observed in both groups after trabeculectomy + phacoemulsification + IOL implantation. Surgical success was defined according to the following 2 criteria: criterion A: IOP≤21mmHg, criterion B: IOP≤18mmHg. Complete success, and qualified success is defined as patients met these criteria with medical treatment(≤3 medications). <p>RESULTS: The visual acuity was improved, with IOP and the number of anti-glaucoma medications used both reduced in both group after surgery. There was no statistically significant difference in complete and qualified success rates between the two groups at 1 and 3mo after surgery(<i>P</i>>0.05). Postoperative 6mo, 1 and 2a, for criterion A: the qualified success rates in PXG group(90%, 80%, 74%)were slightly lower than that of POAG group(91%, 86%, 82%, <i>P</i>>0.05). The complete success rates in PXG group(50%, 40%, 29%)were significantly lower than that of POAG group(85%, 64%, 61%, <i>P</i><0.05). For criterion B: the qualified success rates in PXG group(70%, 70%, 59%)were slightly lower than that of POAG group(80%, 80%, 75%, <i>P</i>>0.05). The complete success rates in PXG group(45%, 30%, 18%)were significantly lower than that of POAG group(78%, 61%, 54%, <i>P</i><0.05).<p>CONCLUSION: The combined glaucoma-cataract surgery in PXG and POAG patients can significantly improve visual acuity and reduce intraocular pressure. The short-term success rates of both types of glaucoma were similar, however the long-term success rates of PXG patients was significantly lower, and it was difficult to achieve a low level IOP. |
