Abstract


Objective To evaluate the clinical effects of anterior chamber maintainer to exchange infusing tube on sclera incision in intravitreal antibiotics associated with vitrectomy for exogenous infectious endophthalmitis.Methods The clinical data of 33 cases (33 eyes) with exogenous infectious endophthalmitis were analyzed retrospectively. 15 patients(15 eyes) carried out vitrectomy using the anterior chamber maintainer. In this process, only 2 sclera incisions are working. (Group I). These eyes were compared with 18 eyes that had pars plana vitrectomy using the classical three sclerotomy site pars plana approach (Group II) , In this process,all sclera incisions are working For all patients, We record the preoperative and postoperative complications. e.g. The circumstance of removing IOFB and visual function after the operation, IOP and complication of corneal, humor vitreous and retinal.Results 7 days after operation, the records, with 1 months follow-up on the visual functionality for both two groups, did not show significant difference (P>0.05), IOFB was removed for group I and group II in 7cases (87.5%) and 8 cases (88.89%), respectively, which indicates insignificant difference (P>0.05). The contrast of the corneal edema afer the operation between two groups has no statistic difference (P>0.05). the comparison on high intraocular between two groups has no statistic difference (P>0.05), where there were 3 cases in the group II with percentage 16.67% and 1 cases in the group I with percentage 6.67%. After cure, this difference turned out to be insignificant (P>0.05) based on the observation within 1 months; the contrast of the detachment of retina after the operation for 1 months revealed obvious difference (P<0.05); the contrast of the average duration of controlling intraocular infections has no statistic difference (P>0.05).Conclusions The differences between the two groups were insignificant in the clinical effects. Through the ACM, the B.S.S is smooth and safe from anterior segment to posterior segment in eyeball. And the feasibility of the associated surgery increased following. One sclera incision decreased, one factor of complications eliminated, and then, the operation process was reducing, and the achievement ratio was increasing. The anterior chamber infusing tube can take the place of infusing tube on sclera incision in intravitreal antibiotics associated with vitrectomy for exogenous infectious endophthalmitis.
