PURPOSE: This study aimed to evaluate the relationship between macular structural changes and visual prognosis after pars plana vitrectomy (PPV) for proliferative diabetic retinopathy. METHODS: The study included 60 eyes that had undergone PPV. Macular optical coherence tomography (OCT) findings were classified into 5 groups preoperatively and 10 groups postoperatively. Best-corrected visual acuity (BCVA) were analyzed according to pre- and postoperative OCT. RESULTS: From the preoperative OCT, normal fovea with/without traction, normal fovea with preretinal hemorrhage, and tractional retinal detachment involving fovea showed an increase in BCVA after PPV (all p < 0...

A 60-year-old female came to our hospital with defective vision due to persistent diabetic macular edema and was treated with intravitreal ozurdex implant in the right eye. Three days later, the patient presented with diminution of vision, ocular pain, congestion, and hypopyon with no fundus view. B-scan ultrasonography showed vitritis, and diagnosis of endophthalmitis was made. Subsequently, 25-gauge pars plana vitrectomy was performed along with intravitreal vancomycin and amikacin and removal of implant...

PURPOSE: To determine whether internal limiting membrane (ILM) peeling during pars plana vitrectomy for rhegmatogenous retinal detachment reduces the incidence of epiretinal membrane (ERM) formation. METHODS: In this retrospective study, preoperative, intraoperative, and postoperative data from all eyes undergoing pars plana vitrectomy for rhegmatogenous retinal detachment between January 2007 and December 2013 was analyzed. All cases with at least 1-year of follow-up were included...

Purpose: The purpose of this study was to study the incidence and factors influencing retinal displacement in eyes treated for rhegmatogenous retinal detachment (RRD) with pars plana vitrectomy (PPV) and gas or silicone oil. Methods: This was a prospective observational case series. One hundred twenty-five eyes with macula-off RRD from 125 patients underwent 25-gauge PPV at two vitreoretinal institutional practices. Eyes without proliferative vitreoretinopathy (PVR) or PVR grade A were tamponated with sulfur hexafluoride (SF6) gas, whereas eyes with PVR grade B received 1000 centistokes silicone oil (SO)...

PURPOSE: To assess the impact of sequential and combined surgery [cataract surgery and 23-gauge pars plana vitrectomy (PPV) with peeling] on corneal endothelium cell density (CED) and corneal biomechanical characteristics. METHODS: Phakic eyes with epiretinal membrane (ERM) were prospectively allocated to (i) cataract surgery and subsequent PPV (CAT group), (ii) PPV and subsequent cataract surgery (VIT group) or (iii) phacovitrectomy (COMBI group). Eyes were examined at baseline, 1 month after each surgery, and at 3 and 12 months follow-up...

Today, the widespread use of laser instruments in various fields has resulted in many accidental retinal injuries. Here we describe a rare clinical case of full-thickness macular hole (MH) and focal choroidal excavation (FCE) caused by a 1064-nm Q-switched Nd:YAG laser. After pars plana vitrectomy and the following 14 months, consecutive optical coherence tomography imagings showed closure of the MH. Visual acuity improved even in the absence of the outer retina and in the presence of FCE. We speculate that different focusing effects of the unexpected Nd:YAG laser which target different levels of retinal tissue generates diverse prognosis...

The authors describe a case of presumed endogenous fungal endophthalmitis in an immunocompetent pediatric patient with acute lymphoblastic leukemia. A 15-year-old boy with a history of high-risk B-cell acute lymphoblastic leukemia status post-chemotherapy presented with acute changes in vision in his left eye. Fundus examination revealed a white bi-lobed chorioretinal lesion with overlying vitritis and associated subretinal fluid. Magnetic resonance imaging of the brain revealed small ring-enhancing lesions in the right parietal and left occipital lobes...

PURPOSE: In this retrospective study, we evaluated the anatomical and functional outcomes of patients with rhegmatogenous retinal detachment primarily treated with pars plana vitrectomy in regard to the location of the breaks. Methods. 160 eyes were enrolled in this study, divided into two groups based on break location: the superior break group (115 eyes) and the inferior break group (45 eyes). The main endpoint of our study was the anatomical success at 3 months following surgery. RESULTS: Primary retinal reattachment was achieved in 96...
