Effects of 23-gauge transconjunctival sutureless vitrectomy system for vitreous hemorrhage

Abstract

Objective To investigate the cause of vitreous hemorrhage and the clinical effect of 23-gauge transconjunctival sutureless vitrectomy system in the treatment of vitreous hemorrhage.Methods 52 cases (62 eyes) managed with 23-gauge vitrectomy were retrospectively reviewed.All surgeries were performed in our hospital from June 2010 to February 2011.The follow-up time was 3 to 12 months.The main observed items included the best corrected visual acuity,intraocular pressure,intraoperative and postoperative complications.Results The proliferative diabetic retinopathy (PDR) was the most common cause(26 eyes,41.94％)for vitreous hemorrhage.The second one was branch retinal vein occlusion (BRVO,16 eyes,25.81％).The third and fourth most common causes were age related macular degeneration (ARMD,7 eyes,11.29％) and traumatic vitreous hemorrhage (6 eyes,9.68％).The other causes for vitreous hemorrhage accounted for 11.29％.All surgeries were successfully completed and the best corrected visual acuities were improved in all cases.The mean postoperative intraocular pressure was normal.No intraoperative complications and serious postoperative complications were observed.Conclusion 23-gauge transconjunctival sutureless vitrectomy system is an effective and safe surgical technique in the management of vitreous hemorrhage.
