Assessment of the differences in the short-term clinical outcomes of superotemporal and inferonasal Baerveldt glaucoma implantation surgeries performed <i>via </i>the pars plana route / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To investigate and discover whether different insertion areas for Baerveldt glaucoma implant(BGI)surgery produce different outcomes in terms of the reduction of intraocular pressure(IOP). <p>METHODS: This retrospective study involved the review of cases of patients admitted at Toho University Sakura Medical Center, who underwent BGI surgery <i>via</i> the pars plana route for the treatment of neovascular glaucoma. The patients were divided into two groups the superotemporal insertion group \〖18 eyes in 16 subjects(13 males, 3 females; mean age 62.9±14.4a)\〗 and the inferonasal insertion group \〖17 eyes in 15 subjects(11 males, 4 females; mean age 56.9±10.7a)\〗. The patients were followed up and re-evaluated at 12mo. The IOP reduction rate 12mo after surgery relative to preoperative IOP was compared between the two groups.<p>RESULTS: The mean preoperative IOP was 31.1±10.0 mmHg and postoperative IOP was 14.4±4.5 mmHg in the superotemporal group, whereas for the inferonasal group, the mean preoperative IOP was 34.9±9.7 mmHg and postoperative IOP was 15.9±3.7 mmHg. The IOP reduction rate of the superotemporal group was(50.0±19.0)% and that of the inferonasal group was(51.2±16.3)%. There was no significant correlation between the two groups(Student's<i> t</i>-test, <i>P</i>=0.590).<p>CONCLUSION: There was no difference in the short-term clinical outcomes between superotemporal and inferonasal BGI performed <i>via</i> the pars plana route.
