Pars plana vitrectomy

Margaret A Greven, Loh-Shan B Leung
A 72-year-old female with neovascular macular degeneration refractory to anti-vascular endothelial growth factor injections underwent photodynamic therapy and subsequently developed a macular hole (MH) associated with vitreomacular traction. After a period of observation, the MH enlarged. Pars plana vitrectomy was performed, and the MH was closed successfully. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:270-272.].

PURPOSE: To examine rates of acute infectious endophthalmitis after pars plana vitrectomy (PPV) in eyes that received intraoperative subconjunctival antibiotics versus eyes that did not. METHODS: A retrospective, nonrandomized, comparative case series of 18,886 consecutive cases of transconjunctival 23-, 25-, and 27-gauge PPV over a 5-year period was performed. The impact of prophylactic intraoperative subconjunctival antibiotics on the development of acute infectious postoperative endophthalmitis was examined...

Occult globe rupture is a traumatic dehiscence of the sclera at or posterior to the rectus muscle insertions without a visible eye wall defect on slit lamp examination. Occult scleral ruptures are important because they can be difficult to diagnose, but normally require preoperative protection against external pressure to reduce risk of herniation of ocular contents through the rupture and then urgent surgical repair to restore eye wall structural integrity and achieve optimum prognosis. A deeper than normal anterior chamber with posteriorly retracted plateau iris seen immediately after acute ocular trauma is virtually pathognomonic of posterior globe dehiscence...

Purpose: To report a case of macular hole (MH) secondary to a retinal arterial macroaneurysm (RAMA) which was successfully treated with an autologous transplantation of internal limiting membrane (ILM). Case Report: An 87-year-old female presented with a sudden decrease in central vision in the right eye. A fundus examination revealed a RAMA in the superonasal macular region, a subretinal hemorrhage (SRH), involving the macula, and a sub-ILM hemorrhage. A pars plana vitrectomy (PPV) was performed...

A 67-year-old Chinese man presented with acute loss of vision and pain in the left eye with hypopyon in the anterior chamber. The patient was afebrile with no systemic symptoms at presentation. Diagnosis of endogenous endophthalmitis was made with vitreous tap yielding Klebsiella pneumoniae Pars plana vitrectomy was performed twice to clear the infection. Thorough investigations showed no septic foci. Whole body positron emission tomography CT revealed a rectal tumour and biopsy showed adenocarcinoma. He was treated with neoadjuvant chemoirradiation followed by surgery to resect the tumour...

PURPOSE: To assess the efficacy of ocriplasmin in patients with vitreomacular traction (VMT) syndrome <1,500 μm with or without a full-thickness macular holes of <400 μm. METHODS: In this study, a retrospective analysis of 10 eyes of 10 patients with VMT who were treated with ocriplasmin between December 2014 and January 2016 was performed. Ocriplasmin 0.125 mg was injected only once in all cases. Outcome measures included the detachment of VMT, best-corrected visual acuity, the evaluation of optical coherence tomography, including the closure of full-thickness macular holes, and the reduction of macular edema (if present) and the decrease of metamorphopsia if present...

Purpose: This study aims to quantify the concentration of apolipoprotein A1 (APOA1) and retinol binding protein (RBP4) expressed in the vitreous humors of patients with rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD), rhegmatogenous retinal detachment (RRD), and idiopathic epimacular membrane (IEM). This study also aims to investigate the potential role of APOA1 and RBP4 as biomarkers of RRDCD. Methods: Enzyme-linked immunosorbent assay (ELISA) kits were used to obtain levels of APOA1 and RBP4 from the vitreous humor samples of 76 primary patients...

PURPOSE: To report a case of phacomorphic glaucoma following retinal detachment repair with silicone oil in a pediatric patient. STUDY DESIGN: Case report. METHODS: A chart review was conducted at St. Michael's Hospital and The Hospital for Sick Children (Toronto, Canada), where the patient received ophthalmic care from July 28, 2015 onwards. RESULTS: A 14 year-old boy with a history of traumatic retinal detachment and proliferative vitreoretinopathy in the left eye, requiring two pars plana vitrectomies, membrane peel, and silicone oil tamponade, presented with one-day history of decreased vision in the left eye, severe headache, nausea, and vomiting...

BACKGROUND: Ocular involvement in melioidosis is rare and has devastating outcomes. Although there have been few reports on the condition, Khon Kaen, a city in northeast Thailand, has been called the "capital of melioidosis" due to the high prevalence of the condition in the region. We retrospectively reviewed all admitted cases of melioidosis with ocular involvement from the two largest hospitals in Khon Kaen. We reviewed cases from Srinagarind Hospital (a university hospital) of patients admitted between 1993 and 2016 and from Khon Kaen Hospital (a provincial hospital) of patients who presented from 2012 to 2016...

PURPOSE: The aim of this study is to review anatomical and functional outcomes following macular buckling (MB) in high myopia and to compare such results with those obtained by pars plana vitrectomy (PPV). METHODS: PubMed articles on MB in high myopia (2000-2016) were reviewed. Main outcomes included retinal reattachment and macular hole (MH) closure rates, resolution of myopic foveoschisis (MFS), and postoperative visual acuity. RESULTS: Thirty-one articles included 16 in patients with retinal detachment due to MH (MHRD group), 11 in MFS with or without foveal detachment (MFS group), and 4 in MH patients with MFS (MH-MFS group)...
