ABSTRACT

AIM: To investigate the efficacy and safety of intravitreal injection of Conbercept combined with 25G minimally invasive pars plana vitrectomy(PPV)at the end of surgery for early proliferative diabetic retinopathy(PDR)with vitreous hemorrhage.METHODS: A total of 60 patients(60 eyes)with PDR complicated with vitreous hemorrhage requiring PPV at the Affiliated Eye Hospital of Nanjing Medical University were retrospectively analyzed. Based on the injection timing of Conbercept, the patients were divided into 3 groups: 20 patients(20 eyes)injected at the end of the surgery(group A), 20 patients(20 eyes)injected preoperatively(group B), and 20 patients(20 eyes)without injection(group C). The differences in pre- and post-operative visual acuity, intraocular pressure, intraoperative conditions, prognosis, and complications were analyzed among the 3 groups.RESULTS: There were no significant differences in the preoperative conditions and operation time among the patients. There was no iatrogenic retinal hole or silicone oil tamponade during the operation in the 3 groups, and no recurrent retinal detachment occurred after the operations. Best corrected visual acuity(BCVA)at 1, 3 and 6mo of all groups were improved compared with those before the surgery(P<0.05), and the injection groups(group A and group B)had a significantly better postoperative improvement than the non-injection group(group C), and there were significant differences(P<0.05). The incidence of postoperative late vitreous hemorrhage(1mo after operation)in group A was significantly lower than those in groups B and C(P<0.05). The central retinal thickness of the operated eyes in the injection groups(groups A and B)was significantly lower than that in the non-injection group(group C)at 1, 3 and 6mo after operation(P<0.05).CONCLUSION: Conbercept injection at the end of the surgery and preoperative injection are both safe and effective for early PDR and can significantly improve postoperative visual acuity. However, Conbercept injection at the end of surgery can reduce the risk of late vitreous hemorrhage recurrence, leading to better PPV outcomes and improving patients' retinal and visual function and quality of life.

ABSTRACT

?AIM: To observe the clinical curative effect of the intravitreal injection of anti-VEGF antibody combined with the implantation of Ex-press glaucoma drainage device for neovascular glaucoma ( NG) .?METHODS:A retrospective analysis of 20 patients with NG, who got the intravitreal injection of anti -VEGF antibody combined with the implantation of Ex-press. The visual acuity, intraocular pressure ( IOP ) , iris neovascularization fade and intraoperative and postoperative complications were observed at 1wk, 1, 3 and 6mo postoperatively.?RESULTS:The average IOPs of 20 patients were 47 ± 5.6mmHg, 13.4 ±3.6mmHg, 15.3 ±4.2mmHg, 16.9 ± 5.3mmHg and 18.7 ±6.9mmHg preoperatively and postoperatively 1wk, 1mo, 3mo and 6mo with statistical difference (P<0.05).The intraoperative and postoperative complications of the implantation of Ex-press mainly included early shallow anterior chamber, drainage tube obstruction, filtering bleb scarring. There were 8 eyes with filtering bleb scarring with normal IOP.?CONCLUSION: The intravitreal injection of anti-VEGF antibody combined with implantation of Ex -press is effective for NG, which can significantly reduce the IOP.

ABSTRACT

· AlM:To investigate the effect of compound anisodine on fundus blood circulation after vitrectomy with face-down position. · METHODS: Sixty patients ( 60 eyes ) with rhegmatogenous retinal detachment received vitrectomy with silicone oil tamponade operation, who were randomized divided into treatment group ( 30 eyes ) and control group ( 30 eyes ) .The patients in the treatment group received the subcutaneously injection of compound anisodine hydrobromide by the superficial temporal artery once daily for 14d since postoperative first day.Retinal microcirculation blood flow parameters were recorded with Heidelberg retinal flowmeter postoperative 1d, 1 and 2wk, and were compared between two groups. ·RESULTS: The blood flow parameters ( Vol, Flw, Vel) of control group postoperative 1 and 2wk were significantly less than those postoperative 1d.Otherwise the parameters of treatment postoperative 1 and 2wk were significantly more than those postoperative 1d. The parameters between two groups were significant different ( P · CONCLUSlON: Facing down after vitrectomy with silicone oil tamponade may reduce retinal blood supply, consequently lead to retinal ischemia; compound anisodine can effectively improve the retinal and choroidal microcirculation after vitrectomy with face-down posture, reduce retinal ischemia, and enhance the visual function.
