Timely vitrectomy without intraocular lens removal for acute endophthalmitis after cataract surgery

AIM:To investigate the clinical features,causative organisms and effects of timely vitrectomy and silicone oil tamponade without intraocular lens(IOL)removal in the treatment of acute-onset endophthalmitis after cataract surgery(APCE).METHODS:We retrospectively analyzed the clinical features and microbiological factors in 10 eyes of 10 patients with APCE at Tianjin Medical University General Hospital from January 2010 to December 2018.Data on the clinical features,causative organisms,visual acuity,intraocular pressure(IOP)and complications were collected.The mean follow-up period was 25.5 mo.RESULTS:The mean age of the patients was 71.4 y.The mean time between cataract surgery and the onset of endophthalmitis was 2.0 d.Preoperative visual acuity ranged from no light perception to hand motion.After vitrectomy,the visual acuity increased in nine eyes(90%),and was unchanged in one eye(10%).A significant difference was observed between the mean preoperative(36.3±7.1 mm Hg)and postoperative IOP(14.9±4.3 mm Hg,P<0.05).Staphylococcus epidermidis was isolated in 5 eyes,S.aureus in 2 eyes,and Enterococcus in 1 eye.Postoperative complications mainly included fibrin exudates in the anterior chamber at the early stages in all eyes and temporary IOP elevation in one eye.No retinal detachment or ocular atrophy was observed during the follow-up period.CONCLUSION:Under systemic antibiotic treatment and timely diagnosis,vitrectomy and silicone oil tamponade without IOL removal is a safe and effective method for APCE.
