Abstract:
Objective To compare the clinical effects of 25G+and 27G+pars plana vitrectomy(PPV)for vitreous hemorrhage.Methods Fifty patients(50 eyes)with vitreous hemorrhage treated in the Third Affiliated Hospital of Xinxiang Medical University from December 2019 to August 2022 were selected as the research subjects.The patients were divided into a 25G+group and a 27G+group according to different surgical methods.Patients in the 25G+group underwent 25G+PPV treatment,and patients in the 27G+group underwent 27G+PPV treatment.The operation time and the incidence of intraoperative complications were compared between the two groups.Before surgery and 3 months after surgery,the visual acuity of patients in the 2 groups was examined by using the standard visual acuity chart of early treatment of diabetic retinopathy study(ETDRS)group,and the intraocular pressure of patients in the 2 groups was measured by using the Callon non-contact tonometer.Postoperative complications and subconjunctival hemorrhage scope of patients in the 2 groups were compared.Results There were no significant differences in gender,age,preoperative visual acuity and intraocular pressure of patients between the 25 G+group and the 27G+group(P＜0.05).The operation time of patients in the 25G+group was significantly shorter than that in the 27G+group(P＜0.05).At 1 day after surgery,the subconjunctival hemorrhage scope of patients in the 27G+group was significantly smaller than that in the 25 G+group(P＜0.05).Patients in both the 25 G+and 27 G+groups had significantly better ETDRS visual acuity at 1 day,1 week,1 month and 3 months after surgery compared with before surgery(P＜0.05).There was no statistically significant differencein the ETDRS visual acuity of patients between the two groups at 1 day,1 week,1 month and 3 months after surgery(P＞0.05).The intraocular pressure of patients in the 25G+group was significantly lower than that in the 27 G+group at 1 day after surgery(P＜0.05).There was no significant difference in intraocular pressure of patients between the 25G+group and the 27G+group at 1 week,1 month and 3 months after surgery(P＞0.05).At 1 day after surgery,transient hypotonia was observed in 3 patients in the 25 G+group,while no hypotonia was observed in the 27 G+group.In the 25G+group,13 eyes(52.0％)underwent incision suture due to incision seepage when the scleral puncture cannulae were removed,while in the 27G+group,no scleral incision suture was performed.No iatrogenic injury occurred during the operation in both groups.During the 3-month follow-up,no intraocular infection or choroidal detachment was found in both groups.Conclusion Both 25G+PPV and 27G+PPV can achieve better clinical efficacy in treating vitreous hemorrhage,and the operation is safe and reliable.Compared with 25G+PPV,27G+PPV can significantly reduce subconjunctival hemorrhage and edema and stabilize intraocular pressure of patients.
