Project description:BackgroundTo evaluate the morbidity frequency measures in terms of the cumulative incidence of sympathetic ophthalmia (SO) triggered by single or multiple vitreoretinal (VR) surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction, and to further investigate the relationship between VR surgery and SO.MethodsA literature search was conducted using PubMed, Embase, and Scopus from inception until 11 November 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist for the case series and the Newcastle-Ottawa Scale were used to assess the risk of bias. The research was registered with the PROSPERO database (identifier, CRD42023397792). Meta-analyses were conducted using the measurement of risk and a 95% confidence interval (CI) for each study.ResultsA random-effect meta-analysis demonstrated that the pooled cumulative incidence of SO triggered by single or multiple VR surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction among patients who developed SO regardless of the main trigger, was equal to 0.14 with a CI between 0.08 and 0.21 (I2 = 78.25, z: 7.24, p < 0.01). The pooled cumulative incidence of SO triggered by single or multiple VR surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction among patients who underwent VR surgery, was equal to 0.03 for every 100 people, with a confidence interval (CI) between 0.02% and 0.004% (I2 = 27.77, z: 9.11, p = 0.25).ConclusionsDespite postsurgical SO being a rare entity, it is a sight-threatening disease. VR surgery should be viewed as a possible inciting event for SO and considered when counseling patients undergoing VR surgery.

Project description:With improving prognosis for recipients of liver transplantation, the necessity of medical care for musculoskeletal disorders, including spinal diseases, of these patients is also increasing. Only a few reports are available on cases of spine surgery following liver transplantation. Furthermore, a case of lateral access surgery following liver transplantation has not thus far been reported. The purpose of this study is to present the first two cases of patients treated with lateral access spine surgery following liver transplantation. Case 1. A 49-year-old female had received living donor liver transplantation (LT) for acute-on-chronic liver failure (ACLF) ten years prior to spine surgery. The patient underwent two levels of lateral lumbar interbody fusion (LLIF) followed by posterior lumbar interbody fusion (PLIF) for degenerative lumbar disease. Although neurological symptoms in the lower extremity improved, a liver disorder resulting from acetaminophen-induced hepatotoxicity occurred at an early stage following spine surgery. Case 2. A 66-year-old female had received living donor liver transplantation for hepatocellular carcinoma (HCC) six years prior to spine surgery. She underwent posterior instrumentation surgery followed by a T12 corpectomy using a wide-foot print expandable cage for T12 vertebral collapse. Following surgery, her weakened muscle strength in the lower extremities was significantly improved. Lateral access spine surgery for lumbar and thoracolumbar lesions can be successfully performed for patients following liver transplantation. However, careful follow-up should be performed for complications related to the function of the liver graft following spine surgery.

Project description:The resection of giant pituitary adenomas is one of the most challenging brain surgeries, especially when the giant pituitary adenomas have an irregular shape or irregular growth position. The purpose of the present study is to propose staged surgery for irregular giant pituitary adenomas through a retrospective analysis of two cases. The cases of two patients with irregular giant pituitary adenomas who underwent staged surgery are retrospectively analyzed. In one case, a 51-year-old male was hospitalized after 2 months of memory loss. Brain MRI showed that the pituitary adenoma was paginated and located in the sellar and right suprasellar regions, with a size of ~6.15×6.11×5.69 cm. In the second case, a 60-year-old male had a history of intermittent vertigo for 10 years and paroxysmal amaurosis for 1 year. Brain MRI showed that the pituitary adenoma grew laterally and eccentrically, and was located in the sellar region, with a size of ~4.35×3.96×3.07 cm. Both patients underwent staged surgery; more specifically, the tumors were totally removed through two-stage surgery. In the first-stage operation, most of the tumor was removed by the microscopic transcranial approach, while in the second-stage operation, the residual tumor was removed by the endoscopic transsphenoidal approach. Both patients recovered well without obvious postoperative complications after staged surgery. There was no recurrence during the follow-up. Staged surgery is characterized by only treating tumors in the visual field and achieving a total tumor resection, which has the advantages of a high tumor resection rate, high safety and fewer postoperative complications. Staged surgery is especially suitable for irregular giant pituitary adenomas with an irregular shape or irregular growth position.

Project description:Iron has been implicated in the pathogenesis of age-related retinal diseases, including age-related macular degeneration (AMD). Previous work showed that intravitreal (IVT) injection of iron induces acute photoreceptor death, lipid peroxidation, and autofluorescence (AF). Herein, we extend this work, finding surprising chronic features of the model: geographic atrophy and sympathetic ophthalmia. We provide new mechanistic insights derived from focal AF in the photoreceptors, quantification of bisretinoids, and localization of carboxyethyl pyrrole, an oxidized adduct of docosahexaenoic acid associated with AMD. In mice given IVT ferric ammonium citrate (FAC), RPE died in patches that slowly expanded at their borders, like human geographic atrophy. There was green AF in the photoreceptor ellipsoid, a mitochondria-rich region, 4 h after injection, followed later by gold AF in rod outer segments, RPE and subretinal myeloid cells. The green AF signature is consistent with flavin adenine dinucleotide, while measured increases in the bisretinoid all-trans-retinal dimer are consistent with the gold AF. FAC induced formation carboxyethyl pyrrole accumulation first in photoreceptors, then in RPE and myeloid cells. Quantitative PCR on neural retina and RPE indicated antioxidant upregulation and inflammation. Unexpectedly, reminiscent of sympathetic ophthalmia, autofluorescent myeloid cells containing abundant iron infiltrated the saline-injected fellow eyes only if the contralateral eye had received IVT FAC. These findings provide mechanistic insights into the potential toxicity caused by AMD-associated retinal iron accumulation. The mouse model will be useful for testing antioxidants, iron chelators, ferroptosis inhibitors, anti-inflammatory medications, and choroidal neovascularization inhibitors.

Project description:PurposeSturge-Weber syndrome (SWS) and sympathetic ophthalmia (SO) are unusual pathologies. Their association has not been previously reported. This unusual diagnosis can be elucidated by clinical suspicion.MethodsCase report of a 22-month-old female with SO.ResultsSWS with a unilateral diffuse choroidal hemangioma. The exciting eye had multiple surgeries for glaucoma that required enucleation. Clinical picture of SO was found on the sympathizing eye. Atypical histopathology (nongranulomatous choroidal infiltrate and perivascular mononuclear cells) is found in the enucleated eye.ConclusionsTo the best of the authors' knowledge, this is the first description of an association of SWS, diffuse choroidal hemangioma, infantile glaucoma, and SO. Many confounding factors are present (ie, multiple surgeries, risk of infectious endophthalmitis). Therefore, a high index of suspicion must be kept in mind to make the diagnosis. We aim to raise awareness of such a devastating condition in a pediatric patient with many comorbidities.

Project description:BackgroundTo investigate the clinical manifestations, visual outcomes and optical coherence tomographic (OCT) features of patients with posterior sympathetic ophthalmia (PSO).MethodsWe performed a retrospective review of 48 patients diagnosed with PSO between January 2013 and December 2019. We compared the clinical and OCT features among different clinical types of PSO.ResultsPSO could be classified into two types according to whether the fundus exhibited serous retinal detachment (SRD) or multifocal choroiditis (MFC). There were 41 patients (85.4%) with SRD and 7 patients (14.6%) with MFC. The latent period of patients with MFC was significantly longer than that of patients with SRD (P = 0.002). The final visual acuity of patients with MFC was significantly worse than that of patients with SRD (P = 0.0001). In patients with acute SRD, OCT revealed that the mean height of retinal detachment in the fovea was 528.8 ± 437.5 μm. After treatment, the retina reattached in all patients and the band structures of the outer retina were restored in most patients (92.7%). In patients with acute MFC, the OCT images revealed inflammatory lesions on the retinal pigment epithelium layer. After treatment, the OCT images showed hyperreflective fibrosis of the lesions and loss of the outer retinal band structures in all patients.ConclusionsWe found that PSO could be classified according to the presence of SRD or MFC. The visual prognosis differed significantly between these types of PSO. OCT imaging is useful for clinical classification and monitoring of retinal changes after treatment.

Project description:IntroductionSympathetic ophthalmia (SO) is a rare bilateral granulomatous panuveitis that can follow surgical or nonsurgical ocular trauma in one eye. Because its diagnosis requires clinical-pathologic correlation, the true incidence of SO is unknown, and there is a need to understand the recent trends in risk factors and frequency of this condition.MethodsPathology records of all enucleated or eviscerated (ENEV) eyes at three pathology laboratories were reviewed. Data collected included patient demographics, procedure indication, pathology diagnosis, and clinical history of trauma and uveitis. IRIS® Registry (Intelligent Research in Sight) was searched for all patients with SO, acquired absence of eye (AAE), and/or ENEV. Data obtained included patient demographics, ocular procedures, and preoperative diagnoses within 30 days of AAE/ENEV.ResultsIn the pathology laboratory setting, the incidence of SO over a 36-year period in patients who underwent ENEV was 0.2% (20/9,092); the 5-year incidence ranged from 0.0 to 0.3%. Among the 20 eyes with SO, the inciting event was surgical trauma in 50% (10/20), nonsurgical trauma in 45% (9/20), and missing/undetermined in 5% (1/20). SO was suspected preoperatively in 7/20 (35%) patients. Clinical concern for SO and ruptured globe were indications for ENEV in 50/9,092 (0.5%) and 872/9,092 (10%) patients, respectively. In the IRIS Registry, 0.7% (199/27,830) of patients with AAE/ENEV had diagnosis of SO. The frequency of SO between 2015 and 2020 was 0.01% (7,371/62,318,249); of these 7,371 cases, 199 (3%) had AAE/ENEV. In 25,975 patients with available data, injury and SO were listed as diagnoses less than 30 days prior to AAE/ENEV in 909 (4%) and 63 (0.2%) cases, respectively.ConclusionThe frequency of SO in recent decades has been low. Most cases of SO are not managed with eye removal. In histopathology-confirmed SO, surgical trauma is as frequent as nonsurgical trauma as an inciting etiology of disease.

Project description:To report the vitreoretinal (VR) surgical case mix in the United Kingdom, the intraoperative complication rate of pars plana vitrectomy (PPV), and the incidence of post-vitrectomy cataract extraction.Participating hospitals prospectively collected ophthalmic data using a single electronic medical record system, with automatic extraction of anonymised data to a national database. This study included the subset of 11618 VR operations undertaken on 9619 eyes, of 8741 patients, over 8 years, from 27 sites. Surgical data included the indication for surgery, all procedure elements, and whether or not an intraoperative complication occurred. Post-vitrectomy cataract data were also analysed. The main outcome measures were a description of the indications for surgery, intraoperative PPV complication rate, and percentage of eyes undergoing post-vitrectomy cataract surgery (PVCS).The most common indications for VR intervention were retinal breaks and rhegmatogenous retinal detachment (48.5%), macular hole (9.8%), epiretinal membrane (9.6%), and diabetic eye disease (7.3%). Overall, 7.8% of PPVs had at least one intraoperative complication-the most common were iatrogenic retinal breaks (3.2%), and lens touch (1.2-1.6% of phakic eyes). PVCS occurred in 50.2, 68.7, and 74.0% of eyes at 1, 2, and 3 years, respectively.VR surgery is undertaken for a wide range of conditions, but a small number of diagnoses encompass the majority of cases. Intraoperative PPV complications are not uncommon, and post-vitrectomy cataract is to be expected in most phakic eyes.

Project description:BackgroundThe purpose of this study was to perform a systematic review of the current literature on simulator-based training in vitreoretinal surgery (VRS). We examined the results regarding simulated VRS and provided an overview of how the current results may be employed in VRS training. Lastly, we evaluated the quality of these results.MethodsThe databases of Pubmed, Embase and Cochrane Library were searched for articles in English involving simulated VRS training. A qualitative analysis was performed, since the studies which met our inclusion criteria did not allow for a quantitative meta-analysis.ResultsWe identified 203 articles of which seven met the inclusion criteria. Of these, six studies investigated simulation with EyeSi® Surgical (VRMagic, Mannheim, Germany). Six studies reported positive performance curves. Four studies showed construct validity. One study attempted to show skill transfer from simulator to vitrectomies performed on cadavers. Methodological quality of the included studies was moderate but lacking in instrument validation.ConclusionSimulator-based training in VRS can assess and possibly assist acquisition of a variety of VRS skills. Further research is needed to support transfer from simulator to operating room. Future studies should strive to follow established validation frameworks and streamline study designs.
