PURPOSE: The purpose of this study was to compare ocular and systemic parameters between proliferative diabetic retinopathy (PDR) cases with postoperative vitreous hemorrhage (PVH) and those without PVH after 25-gauge vitrectomy, and to investigate the predictors of PVH. METHODS: The medical records of 106 eyes of 78 consecutive patients who underwent primary 25-gauge vitrectomy were reviewed. RESULTS: The incidences of early and late PVH were found to be 18...

Purpose. Endogenous endophthalmitis (EE) is a rare ocular disease caused by bacterial or fungal infection of intraocular spaces by hematogenous spread of pathogens from distant infectious loci in the body. We investigated the clinical characteristics and management of eyes with EE in ten consecutive patients. Methods. Ten patients (10 eyes) with EE treated at Tokyo Medical University Hospital in 2014 were reviewed. We retrospectively studied the causative organisms, systemic complications, pre/postoperative mean best-corrected visual acuity (BCVA), and status of posterior vitreous detachment (PVD)...

BACKGROUND AND OBJECTIVE: To evaluate the effect of preoperative intravitreal bevacizumab (IVB) (Avastin; Genentech, South San Francisco, CA) injection on the choice of endotamponade at the end of surgery in patients who underwent pars plana vitrectomy (PPV) for diabetic tractional retinal detachment (DTRD). PATIENTS AND METHODS: Seventy-eight patients who had DTRD with macular involvement and underwent PPV by a single surgeon from January 2012 to May 2015 were included...

PURPOSE: To elucidate the current clinical practice patterns of diabetic macular edema (DME) management by retinal specialists in Japan in the era of anti-vascular endothelial growth factor (VEGF) therapy. METHODS: Forty-six retinal specialists were administered a survey regarding the pathology and clinical practice of DME. RESULTS: Nearly, half of the specialists (45.2 %) think that the main biochemical factor involved in DME development is the vascular permeability-potentiating action of VEGF-A...

We were challenged and delighted when Dr. Sharon Solomon, guest editor of this Retina Supplement, invited us to reminisce about caring for patients with common retinal disorders before there was access to the diagnostic and therapeutic tools that are readily available today. We agreed to confine our remarks to 3 common, but serious, conditions: age-related macular degeneration (Dr. Fine), diabetic retinopathy (Dr. Goldberg), and retinal detachment (Dr. Tasman). Each of us completed our ophthalmology training about half a century ago...

Purpose: The purpose of this study was to investigate whether fibrocytes participate in formation of the fibrovascular membrane (FVM) in patients with proliferative diabetic retinopathy (PDR). Methods: Vitreous fluid and FVM samples were obtained during vitrectomy in patients with PDR. Samples from patients with macular hole or epiretinal membrane were used as controls. Vitreous fluid and FVM samples were subjected to immunohistochemical analysis. In addition, cells isolated from the vitreous fluid of PDR and control patients were cultured in serum-free medium...

PURPOSE: To assess the risk and benefit of pars plana vitrectomy for diabetic macular edema. METHODS: The authors conducted a systematic literature review using PubMed, EMBASE, Web of Science, and Cochrane Central Database of Controlled Trials until September 2014. The population was patients with diabetic macular edema, intervention vitrectomy, comparator macular laser or observation, and efficacy outcome visual acuity and central retinal thickness. Safety outcomes were intraoperative and postoperative surgical complications...

PURPOSE: To examine the effect of internal limiting membrane (ILM) removal on epiretinal membrane (ERM) surgery by comparing best-corrected visual acuity (BCVA), optical coherence tomography central macular thickness (CMT) changes, ERM recurrence, and need for repeat surgery. METHODS: Retrospective study of 251 consecutive patients (251 eyes) who underwent pars plana vitrectomy for idiopathic ERM by a single surgeon with over 1 year of follow-up data. Data were collected preoperatively and postoperatively at 3 months, 1 year, 2 years, and at the last visit...

PURPOSE: To investigate the outcomes of pars plana vitrectomy (PPV) for chronic diabetic traction macular detachment (CTMD). METHODS: Ninety-six eyes that underwent PPV for CTMD of at least 6 months duration were retrospectively analyzed. Retinal reattachment rate, final vision, and prognostic factors for poor visual outcome were the main outcome measures. RESULTS: All eyes had long-standing TMD (median 12, range: 6-70 months). The median postoperative follow-up was 15 (range: 3-65) months...

New modalities for the treatment of diabetic eye complications have emerged in the past decade. Nevertheless, many severe diabetic retinopathy complications can only be treated with vitreoretinal surgery. Technological advances in pars plana vitrectomy have expanded the gamut of pathologies that can be successfully treated with surgery. The most common pathologies managed surgically include vitreous opacities and traction retinal detachment. The indications, surgical objectives, adjunctive pharmacotherapy, microincisional surgical techniques, and outcomes of diabetic vitrectomy for proliferative diabetic retinopathy and diabetic tractional retinal detachment will be discussed...

PURPOSE: We describe a patient with endogenous endophthalmitis caused by Acinetobacter spp. as the first clinical presentation of diabetes mellitus. METHOD: A 48-year-old otherwise healthy woman was referred with signs and symptoms of acute endophthalmitis in the left eye. Systemic work-up, vitreous tap, and intravitreal antibiotic injection were performed followed by pars plana vitrectomy. RESULTS: The laboratory tests confirmed the diagnosis of diabetes mellitus...

BACKGROUND: Endogenous Klebsiella pneumoniae endophthalmitis (EKPE) is a well-known entity in South-East Asia. We demonstrate a range of differing clinical features and outcomes of EKPE, and highlight the increasing incidence of EKPE in major centres in Sydney and Melbourne, Australia. DESIGN: Retrospective observational case study and case series in the hospital setting. PARTICIPANTS: Four cases of EKPE. METHODS: EKPE cases from 2005 to 2015 were identified through established endophthalmitis databases as well as hospital-based microbiological searches...

Importance: Diabetic retinopathy (DR) is a devastating complication of individuals with type 2 diabetes mellitus. The retina is rich in long-chain ω-3 polyunsaturated fatty acids (LCω3PUFAs), which are substrate for oxylipins with anti-inflammatory and antiangiogenic properties. Experimental models support dietary LCω3PUFA protection against DR, but clinical data are lacking. Objective: To determine whether LCω3PUFA intake relates to a decreased incidence of sight-threatening DR in individuals with type 2 diabetes older than 55 years...

BACKGROUND: Diabetic retinopathy (DR) is a severe ocular complication of diabetes. Kallistatin has multiple biological functions including anti-inflammation and antiangiogenesis. Our aim was to detect the level of kallistatin in the vitreous of proliferative DR (PDR) and its effect on proliferation, migration, and tube formation of human retinal endothelial cells (HRECs) under high glucose in an in vitro model. METHODS: Vitreous humor samples were obtained through pars plana vitrectomy from 7 nondiabetic patients with idiopathic macular holes or idiopathic preretinal membranes and 10 PDR patients...

PURPOSE: To determine whether intravitreal triamcinolone acetonide (IVTA) is effective in resolving edema in eyes with persistent diabetic macular edema (DME) after vitrectomy. PATIENTS AND METHODS: Sixteen eyes of 16 patients were given 4 mg IVTA after vitrectomy for DME. The best-corrected visual acuity (BCVA), central macular thickness (CMT), and average threshold (AT) of the central retina were determined during the 24 weeks follow-up period. Patients were divided into two groups; early treatment group and late treatment group...
