Sixty-five years of sympathetic ophthalmia. A clinicopathologic review of 105 cases (1913--1978)

FUNGAL ENDOPHTHALMITIS MASQUERADING AS SYMPATHETIC OPHTHALMIA

PURPOSE

To describe the ocular pathology of a patient with fungal endophthalmitis with features mimicking sympathetic ophthalmia.

METHODS

Review of medical records and histopathology of a single patient.

RESULTS

A 72-year-old man who sustained penetrating injury to the left eye with an agave plant presented to our clinic 16 months after the initial injury. Before presentation, the patient had developed endophthalmitis and had undergone anterior chamber washout, vitrectomy, and intravitreal steroids, antibiotics, antifungals, and anti-vascular endothelial growth factor therapy. At presentation, the patient had a blind, painful eye and subsequently underwent enucleation. Histopathology demonstrated granulomatous inflammation with multinucleated giant cells in the iris and Dalen-Fuchs nodules with CD68-positive epithelioid histiocytes associated with the retinal pigment epithelium sparing the choriocapillaris. These findings were initially attributed to sympathetic ophthalmia. The fellow eye did not have any signs of inflammation, and Grocott methenamine silver stain was positive for filamentous fungal elements, leading to a diagnosis of fungal endophthalmitis.

CONCLUSIONS

Fungal endophthalmitis may develop histopathologic features that are similar to those observed in sympathetic ophthalmia. Recognition of the overlap between the histopathologic features of these diseases may reduce the possibility of misdiagnosis and unnecessary treatment of the fellow eye.

Long-term clinical outcomes of patients with sympathetic ophthalmia

PURPOSE

To present the long-term clinical outcomes of patients with sympathetic ophthalmia (SO).

METHODS

Retrospective review of patients' medical files between 2002 and 2022.

RESULTS

Included were seven patients (four males). The mean ± SD age at presentation was 37.9 ± 22.5 years. Four patients had co-morbidities: three had diabetes mellitus type 2 and one had Turner Syndrome. Trauma was the inciting event in six patients and postoperative endophthalmitis in one patient. Decreased visual acuity (VA) was the leading symptom in the sympathizing eye and all of the patients presented with panuveitis. The mean ± SD interval between the triggering incident and the onset of SO in six cases was 4.3 ± 4.2 months. One case presented 30 years following the eye injury. Five patients underwent enucleation/evisceration of the exciting eye. The mean ± SD presenting LogMAR BCVA in the sympathizing eye was 0.57 ± 0.82, and the final LogMAR BCVA was 0.61 ± 0.95. Inflammation was completely controlled in 5 patients at a mean ± SD of 8.55 ± 9.21 months following the institution of immunomodulatory therapy, and it was partially controlled in 2 patients. VA deteriorated in all 3 diabetic patients and improved or remained stable in the 4 young and healthy patients. The mean ± SD follow-up period after achieving drug-free remission was 28 ± 22.8 months. The mean ± SD follow-up time was 6.8 ± 5.6 years.

CONCLUSIONS

SO is one of the most sight-threatening conditions, affecting the healthy eye. In this cohort, the favorable visual outcome was especially seen in young and healthy individuals. Visual prognosis is directly related to prompt diagnosis and treatment.

The Epidemiology and Risk Factors for the Progression of Sympathetic Ophthalmia in the United States: An IRIS Registry Analysis

PURPOSE

To investigate the demographic and clinical characteristics of patients with sympathetic ophthalmia (SO) and define the risk factors for its incidence following trauma and ophthalmic procedures.

DESIGN

Retrospective cohort study.

PARTICIPANTS

Patients in the American Academy of Ophthalmology's (Academy) IRIS Registry (Intelligent Research in Sight) who were (n=1523) or were not diagnosed with SO following a documented procedure or trauma between January 1, 2013, and December 31, 2019.

METHODS

Multiple demographic and clinical factors were collected, descriptive statistics and prevalence were calculated, and multivariate linear regression models were fit to the data.

MAIN OUTCOME MEASURES

Prevalence of SO, demographic and clinical characteristics, and beta coefficient (β) estimates of demographic and clinical characteristics impacting time to SO onset after procedure (Procedure Only cohort) or trauma (Trauma cohort).

RESULTS

Of 65,348,409 distinct IRIS Registry patients, 1523 (0.0023%) were diagnosed with SO between 2013 and 2019, and also had a documented preceding trauma or procedure. Of these, 927 (60.87%) were female, 1336 (87.72%) belonged to the Procedure Only cohort, and 187 (12.28%) belonged to the Trauma cohort. The prevalence of SO after trauma was 0.0207%, whereas after procedures it was 0.0124%. The highest risk of procedure-related SO was seen in patients with history of "other anterior segment" (0.122%) followed by glaucoma (0.066%) procedures, whereas the lowest prevalence was noted with cataract surgeries (0.011%). The average time to onset of SO across both cohorts combined was 527.44 (±715.60) days, with statistically significant differences between the 2 cohorts (P < .001). On average, the time to onset from inciting event to SO was shorter with increasing age, by 9.02 (95% CI: -11.96, -6.08) days for every 1-year increase.

CONCLUSIONS

SO following trauma and ophthalmic procedure is potentially rarer than previously reported, as measured in this large ophthalmic medical record database. Female sex may be a risk factor for SO. Older age may be a risk factor for quicker onset. These findings can guide clinical decision-making and management.

Material risk: vitreoretinal surgery, evisceration, enucleation and sympathetic ophthalmia-where are we currently?

Sympathetic ophthalmia (SO) is known to occur after severe penetrating eye injury, evisceration and even enucleation surgery. Recent evidence suggests that a greater risk lies after multiple vitreoretinal procedures. The risk of SO following evisceration is only minimally greater than that following enucleation surgery. This review evaluates literature on SO to date and provides figures for the risk of developing SO for the purposes of the consent process. The issue of SO and Material Risk following vitreoretinal surgery is reviewed and figures for the purposes of consent are outlined. This is of particular relevance for patients in whom the contralateral eye is and will likely remain the better seeing eye. Sympathetic ophthalmitis is known to occur after severe penetrating eye injury, after evisceration and enucleation. More recently, sympathetic ophthalmitis has been recognised to occur after vitreoretinal surgery. This article reviews the evidence on material risk when consenting patients for elective and emergency eye procedures after ocular trauma or surgery. When a globe needs to be removed because of irreparable ocular injury, previous publications dictated the procedure to be an enucleation because of the fear of an increased risk of SO after an evisceration. Perhaps the issue of material risk of sympathetic ophthalmia (SO) remains over-emphasised by ophthalmic plastic surgeons and under-recognised by vitreoretinal surgeons during the consent process for evisceration, enucleation and vitreoretinal surgery. Antecedent trauma and number of previous surgeries may actually be a more significant risk factor than the type of eye removal. Recent medicolegal cases also help us understand the importance of the discussion of this risk. We present our current understanding of the risk of SO after different procedures and suggest how this information may be included in a patient consent.

Vision Outcomes of Long-Term Immunomodulatory and Steroid Therapy in Sympathetic Ophthalmia

PURPOSE

To compare vision acuity outcomes of long-term steroid therapy compared with immunomodulatory therapy for treatment of sympathetic ophthalmia.

DESIGN

Single-center, retrospective, comparative clinical study.

METHODS

Patients with sympathetic ophthalmia treated from March 2005 to October 2022 with at least 1 year of follow-up were included. Visual acuity outcomes were compared by steroid and immunomodulatory treatment modality.

RESULTS

Thirty-five patients with sympathetic ophthalmia were included in the study, with follow-up ranging from 1 to 17 years. Higher rates of vision loss correlated with longer periods of active uveitis and steroid treatment. Lower rates of vision loss correlated with longer periods of uveitis remission on immunomodulatory therapy alone and drug-free remission. Treatment with alkylating agents or combination therapy with an antimetabolite, a biologic-response modifier, and cyclosporine are more likely to result in sympathetic ophthalmia remission.

CONCLUSION

Immunomodulatory therapy leads to superior vision outcomes in cases of steroid-resistant or recurrent sympathetic ophthalmia. Steroid therapy may be useful for acute or recalcitrant sympathetic uveitis but is insufficient for long-term inflammatory control. PRéCIS: This manuscript describes a retrospective analysis of vision outcomes in patients with sympathetic ophthalmia. Results indicate that long-term immunomodulatory therapy is associated with better vision outcomes than long-term steroid therapy for sympathetic ophthalmia treatment.

An atypical presentation of sympathetic ophthalmia following chemical ocular burns

BACKGROUND

Sympathetic ophthalmia is a rare disease that can present as bilateral granulomatous uveitis after a penetrating trauma or surgery in one eye.

FINDINGS

We report a case of a 47-year-old male with history of decreased vision in the right eye, six months after sustaining severe chemical injury in the left eye. He was diagnosed with sympathetic ophthalmia and was treated with corticosteroids and long-term immunosuppressive therapy, leading to complete resolution of intraocular inflammation. Final visual acuity was 20/30 at one year of follow up.

CONCLUSIONS

Sympathetic Ophthalmia following chemical ocular burns is extremely uncommon. It can present as a diagnostic and therapeutic challenge. It warrants early diagnosis and management.

The Ocular Trauma Score Underestimates Visual Recovery for the Most Severe Open-Globe Injuries

PURPOSE

To compare visual outcomes after open-globe injury (OGI) with those predicted by the Ocular Trauma Score (OTS), and to investigate the effect of treatment with pars plana vitrectomy (PPV).

DESIGN

Retrospective cohort study.

SUBJECTS

Patients presenting with OGI to an academic United States ophthalmology department from 2017 to 2020.

METHODS

Best-corrected visual acuity (VA) measurements at the most recent follow-up were compared with final VA predicted by the OTS, based on preoperative injury characteristics. The most recently measured VA of patients treated with PPV during initial OGI repair (primary PPV group) was compared with patients treated with PPV after initial OGI repair (secondary PPV group) and patients never treated with PPV (No PPV group).

MAIN OUTCOME MEASURES

Best-corrected VA in the injured eye at last follow-up; secondary outcome measures included the occurrence of vitreous hemorrhage at any time, occurrence of retinal detachment at any time, rates of additional surgery, and rates of enucleation.

RESULTS

One-hundred and thirty-three subjects with OGI were identified and analyzed. The overall rate of PPV was 32%. Predictors of worse VA at last follow-up included older age (P = 0.047) and worse presenting VA (P < 0.001). Visual acuity outcomes for eyes in OTS categories 2 to 5 did not significantly differ from OTS predictions. However, eyes in OTS category 1 had a higher likelihood of last follow-up VA of light perception (LP) to hand motion (46% in the study cohort vs. 15% predicted by the OTS, P = 0.004) and a lower likelihood of no LP (33% vs. 74%, P < 0.001). The secondary PPV group had the worst VA at presentation among the 3 groups (P = 0.016), but VA at last follow-up did not significantly differ between the study groups (P = 0.338).

CONCLUSIONS

The most severe OGIs (i.e., OTS category 1) had better visual outcomes than predicted by the published OTS expectations, and secondary PPV was associated with significant visual improvement despite poor prognostic predictions. Evaluation by a vitreoretinal surgeon should be considered for all patients with severe OGI, especially those in OTS category 1.

Outcome Measures for Disease Monitoring in Intraocular Inflammatory and Infectious Diseases (OCTOMERIA): Understanding the Choroid in Uveitis with Optical Coherence Tomography (OCT)

PURPOSE

To compare imaging modalities for the choroid of the eye, and evaluate various choroidal changes in uveitides entities.

METHODS

A comprehensive systematic literature review was conducted looking at current imaging modalities available to assess choroid architecture and commonly used parameters available to qualify and quantify choroidal changes, before looking at specific uveitides entities with choroidal involvement which have been broadly separated into non-infectious and infectious in etiology.

RESULTS

We describe the various modalities currently available to evaluate the choroid of the eye such as Ultrasound B Scan, ICGA, and OCT. Choroidal changes in various ocular and systemic diseases such as Behcet's Disease, Sarcoidosis, Syphillis, Tuberculosis, and many more have been reported and published.

CONCLUSION

Multiple choroidal tomographic and angiotomographic findings have been demonstrated for evaluation in uveitis. These findings can manifest in multiple ocular and systemic diseases, and can be illustrated using the various imaging modalities at present. Future advancements in choroidal imaging would help to adapt these findings into parameters for clinical practice to properly evaluate these ocular and systemic diseases.

Sympathetic ophthalmia: A comprehensive update

Sympathetic ophthalmia is a rare, bilateral, granulomatous, panuveitis following penetrating trauma or surgery to one eye. Clinical presentation commonly occurs within the first year of trauma occurrence but can be delayed by several years. It manifests as acute/chronic granulomatous uveitis with yellowish-white choroidal lesions or Dalen-Fuchs nodules. Initially, patients respond rapidly to corticosteroid therapy, but a majority require long-term use of corticosteroid-sparing agents to prevent recurrences. The purpose of this review is to elaborate on the current understanding of the pathophysiology, the importance of multimodal imaging in early diagnosis, and the role of newer immunomodulatory and biological agents in recalcitrant cases.

Sympathetic Ophthalmia - An Overview

INTRODUCTION

Sympathetic ophthalmia (SO) is rare, bilateral granulomatous panuveitis that typically occurs following penetrating or perforating ocular trauma or surgery. This review aims to provide an update on the etiopathogenesis, clinical presentations, diagnosis and treatment of SO.

METHODS

Reports cited in MEDLINE database, that analyzed SO in at least 5 patients, published prior to December 1st, 2021 were included.

RESULTS

Initially, SO was associated with penetrating ocular trauma, however, various studies reported an increased incidence of SO after surgical procedures including vitreoretinal surgeries. Multimodal imaging including fluorescein and indocyanine green angiography, optical coherence tomography (OCT) and OCT angiography have added further insights into the understanding of SO. While pulse dose corticosteroids & immunosuppressive drugs are still the treatment of choice, TNF-α blockers & other biologic drugs represent new promising agents.

CONCLUSION

There is a growing pool of evidence in understanding the pathogenesis of SO. Novel treatment options have provided better prognosis for this potentially blinding condition.

The Incidence of Sympathetic Ophthalmia After Trauma: A Meta-analysis

PURPOSE

Sympathetic ophthalmia (SO) is a rare, bilateral panuveitis that occurs following open globe injury (OGI), with a variable incidence reported in the literature. Our objective was to determine the incidence proportion and incidence rate of SO following OGI to help guide shared physician-patient decision making.

DESIGN

Systematic review and meta-analysis.

METHODS

A systematic literature search was performed using the MEDLINE, EMBASE, and Cochrane databases from inception to November 2020 for population-based studies on OGI and SO in adults and children. Two reviewers independently screened search results. Random-effects meta-analyses were performed to calculate the incidence proportion and incidence rate. The Risk Of Bias In Non-Randomized Studies - of Interventions (ROBINS-I) tool was used to assess the risk of bias. The study was registered on PROSPERO CRD42020198920.

RESULTS

A total of 24 studies were utilized in the meta-analyses. After OGI, the estimated overall incidence proportion of SO was 0.19% (95% CI 0.14%-0.24%) and the incidence rate of SO was 33 per 100,000 person-years, (95% CI 19.61-56.64) with I² of 13% and 72%, respectively.

CONCLUSIONS

SO after OGI is rare. The estimated incidence proportion and incidence rate are useful when counselling patients regarding management options after OGI. Further studies are needed to examine the influence of age, the extent and location of trauma, timing of repair, and prophylactic eye removal on the incidence of SO.

Clinical and imaging features of sympathetic ophthalmia and efficacy of the current therapy

PURPOSE

The purpose of the study was to clarify the clinical and imaging features of sympathetic ophthalmia (SO) and evaluate the efficacy of the current therapy.

METHODS

The databases PubMed, EMBASE and Ovid up to January 2021 were searched to identify relevant studies. R software version 3.6.3 was used to perform the statistical analyses.

RESULTS

Thirty-two studies involving 1067 patients were finally included. Our study found SO was male-dominated, and more than half of SO patients aged 16 to 60 years old. Ocular trauma, surgical interventions and unknown events were estimated to be inciting events in 63%, 36% and 4% of SO patients. About 35% of the patients underwent baseline enucleation, and 45% took compelled enucleation during follow-up. The most common symptoms at the first presentation were decreased vision, followed by pain and redness. The most common signs were anterior chamber cells/flare, followed by vitritis, exudative retinal detachment and Dalen-Fuch nodules. Choroidal thickening was detected in 81% of SO patients by ocular ultrasound. The most common fluorescein fundus angiography signs were disc leakage. After corticosteroid therapy became the mainstay for SO, about 76% of SO patients could get inflammation well-controlled, while 24% of them might have recurrent inflammation. Around 72% of SO patients could achieve visual improvement, and more than half of them might have a best-corrected visual acuity of 20/50 or better.

CONCLUSION

SO is a complicated ocular disease with diverse clinical manifestations and imaging features. After proper anti-inflammation therapy, SO might not necessarily result in a poor prognosis.

Recent advances in diagnosis and management of sympathetic ophthalmia

PURPOSE OF REVIEW

Sympathetic ophthalmia is a bilateral granulomatous uveitis that occurs following unilateral trauma or surgery and is sight-threatening in the contralateral eye. Despite significant potential morbidity, disease remains poorly understood. Variable presentations and clinical courses, as well as a lack of definitive diagnostic laboratory tests can complicate the diagnosis and result in delayed treatment, which can beget permanent vision loss. This review focuses on recent advances in areas of pathophysiology, classification, diagnosis and treatment.

RECENT FINDINGS

Sympathetic ophthalmia is thought to involve a cell-mediated immune response to retinal and uveal antigens exposed through trauma or surgery. Multiple mechanisms have been implicated, including activation of the interleukin-23/IL-17 pathway. Ongoing emphasis is placed on early disease recognition and prompt treatment with multimodal imaging. Multiple authors advocate for the routine use of optical coherence tomography (OCT) for screening and disease monitoring. Systemic steroids and steroids sparing-immunosuppressive agents remain the mainstay of treatment.

SUMMARY

Understanding pathophysiology may provide useful targets for drug development, as well as allow for identification of patients at risk. OCT is a useful tool in early diagnosis and management of sympathetic ophthalmia, as OCT changes may precede clinical symptoms and signs, allowing for early disease detection and better visual outcomes.

Sympathetic Ophthalmia: Where Do We Currently Stand on Treatment Strategies?

Sympathetic ophthalmia is a rare bilateral diffuse granulomatous panuveitis that usually results from surgical or penetrating trauma to one eye. The symptoms range from impaired near vision to pain, photophobia, and loss of visual acuity. Anterior segment manifestations include bilateral acute uveitis with mutton-fat keratic precipitates and posterior segment findings include vitritis, multifocal neurosensory retinal detachment, choroiditis, optic nerve edema, and Dalen-Fuchs nodules. The diagnosis is clinical. Ancillary investigations include fundus fluorescein angiography, indocyanine green angiography, optical coherence tomography (OCT), ultrasound B scan, and autofluorescence imaging. The management options include corticosteroids (topical and systemic) as the first line along with immunomodulatory therapy started at the presentation of the disease. Recent advances include imaging with OCT-angiography, enhanced depth imaging-OCT (EDI-OCT, choroidal vascular index/CVI), targeting IL-23/IL-17 pathway, and use of biologics for the management of this rare entity. Recent advances in early diagnosis and prompt treatment has led to improved final visual outcomes in both the sympathizing and exciting eye. This review is aimed at giving a comprehensive overview of sympathetic ophthalmia along with a special emphasis on current treatment strategies and recent advances.

The Ruptured Globe, Sympathetic Ophthalmia, and the 14-Day Rule

PURPOSE

Prophylactic enucleation of a ruptured globe with no light perception within 14 days of injury to prevent sympathetic ophthalmia (SO) has been an established dictum in academic teaching for more than 100 years. This treatment strategy was originally based on observation, speculation, and careful thought, but there was never any scientific proof. This review summarizes and updates the current state of our knowledge about globe rupture and SO, examines the origin and validity of the 14-day rule, and emphasizes the importance of trying to save the traumatized eye whenever possible.

METHODS

A comprehensive literature review of SO and globe rupture was performed.

RESULTS

SO is a rare disorder that may potentially occur following traumatic globe rupture as well as following a variety of other intraocular surgeries. Vitreoretinal surgery may be a more common cause than trauma according to some studies. SO may still occur despite having the eye removed within 14 days of the trauma. A variety of new medications including biologic agents are now available to treat SO with improved efficacy in suppressing the associated ocular inflammation and allowing retention of some useful vision. Removing the traumatized, blind eye may have other important psychological consequences associated with it that require consideration before eye removal is carried out. Retaining the blind, phthisical, disfigured eye avoids phantom vision and phantom pain associated with enucleation as well as providing a good platform to support and move an overlying prosthetic eye. Data on the occurrence of SO following evisceration and enucleation with and without predisposing factors confirms the exceedingly low risk.

CONCLUSION

Most civilian open globe injuries can be successfully repaired with modern, advanced microsurgical techniques currently available. Because of the exceedingly low risk of SO, even with the severity of open globe trauma during military conflicts being more devastating as a result of the blast and explosive injuries, today every attempt is made to primarily close the eye rather than primarily enucleate it, providing there is enough viable tissue to repair. The 14-day rule for eye removal after severe globe ruptures is not scientifically supported and does not always protect against SO, but the safe time period for prophylactic eye removal is not definitively known. In the exceptional cases where SO does occur, several new medications are now available that may help treat SO. We advocate saving the ruptured globe whenever possible and avoiding prophylactic enucleation to prevent the rare occurrence of SO. When an eye requires removal, evisceration is an acceptable alternative to enucleation in cases that do not harbor intraocular malignancy.

Incidence of Sympathetic Ophthalmia after Inciting Events: A National Database Study in Japan

PURPOSE

To analyze the incidence of sympathetic ophthalmia (SO) after inciting events (eye trauma or intraocular surgery).

DESIGN

Retrospective cohort study.

PARTICIPANTS

Patients experiencing inciting events between 2012 and 2019. Onset of SO was defined as the first date of SO diagnosis.

METHODS

Using a nationwide administrative claims database in Japan, we calculated the cumulative incidence of SO after inciting events stratified by sex, 10-year age groups, and a categorical variable of primary or repeated, reflecting the history of inciting events in the past year (no inciting events, inciting events without trauma, or inciting events with trauma) using the Kaplan-Meier approach. We also estimated the adjusted hazard ratio (aHR) by Cox regression. We then restricted the population to those with only 1 inciting event during the observation period to investigate the pure effect of each inciting event.

MAIN OUTCOME MEASURES

Cumulative incidence of SO over 60 months.

RESULTS

A total of 888 041 inciting events (704 717 patients) were eligible. The total number of SO cases was 263, and the cumulative incidence of SO was 0.044% over 60 months. Female sex was not associated with onset of SO (aHR, 1.01; 95% confidence interval [CI], 0.79-1.29; P = 0.95). The group 40 to 49 years of age showed the highest incidence of 0.104% among the age groups (aHR vs. ≥80 years of age group [0.041%], 2.44 [95% CI, 1.56-3.80]; P < 0.001). Repeated inciting events with and without trauma showed higher incidences of SO (0.469% and 0.072%, respectively) than primary inciting events (0.036%) (aHR 11.68 [7.74-17.64] and 2.21 [95% CI, 1.59-3.07], respectively); P < 0.001 and P < 0.001, respectively). The incidence of SO after vitrectomy was much lower than after trauma (0.016% vs. 0.073%), and the incidence after scleral buckling was even lower.

CONCLUSIONS

The cumulative incidence of SO over 60 months was estimated to be 0.044% at minimum. Repeated inciting events, especially those with trauma, increased the risk of SO developing. Trauma was 4 to 5 times as likely to induce SO than vitrectomy. The present findings will be valuable for counseling patients about the risks of SO after trauma and before performing intraocular surgeries.

Sympathetic ophthalmia after vitreoretinal surgery: a report of two cases

Sympathetic ophthalmia (SO) is a panuveitis that usually occurs after trauma to one eye. We describe two cases of SO occurring after 23-gauge vitrectomy. Case 1 involved a 66-year-old woman who underwent pars plana vitrectomy (PPV) for a rhegmatogenous retinal detachment. Two months later, she presented with decreased visual acuity (VA) and bilateral uveitis. Case 2 involved a 43-year-old woman who underwent a second PPV for recurrent retinal detachment. Two months later, she presented with bilateral panuveitis. Both patients were diagnosed with SO and were treated with methylprednisolone and cyclosporine. The first patient was further treated with a dexamethasone intravitreal implant (Ozurdex®) owing to the side effects of methylprednisolone. The VA and symptoms improved significantly after treatment in both patients. Bilateral granulomatous panuveitis following PPV should alert surgeons to consider SO. Appropriate interventions for SO can produce positive outcomes.

Classification Criteria for Sympathetic Ophthalmia

PURPOSE

The purpose of this study was to determine classification criteria for sympathetic ophthalmia.

DESIGN

Machine learning of cases with sympathetic ophthalmia and 5 other panuveitides.

METHODS

Cases of panuveitides were collected in an informatics-designed preliminary database, and a final database was constructed of cases achieving supermajority agreement on the diagnosis using formal consensus techniques. Cases were split into a training set and a validation set. Machine learning using multinomial logistic regression was used in the training set to determine a parsimonious set of criteria that minimized the misclassification rate among the panuveitides. The resulting criteria were evaluated in the validation set.

RESULTS

A total of 1,012 cases of panuveitides, including 110 cases of sympathetic ophthalmia, were evaluated by machine learning. The overall accuracy for panuveitides was 96.3% in the training set and 94.0% in the validation set (95% confidence interval: 89.0-96.8). Key criteria for sympathetic ophthalmia included bilateral uveitis with 1) a history of unilateral ocular trauma or surgery and 2) an anterior chamber and vitreous inflammation or a panuveitis with choroidal involvement. The misclassification rates for sympathetic ophthalmia were 4.2% in the training set and 6.7% in the validation set.

CONCLUSIONS

The criteria for sympathetic ophthalmia had a low misclassification rate and appeared to perform sufficiently well for use in clinical and translational research.

Sympathetic ophthalmia following blunt injury to phthisical eye

Sympathetic ophthalmia is a severe sight-threatening disorder that can lead to blindness if not diagnosed and managed appropriately. It occurs most commonly following penetrating ocular injury and less commonly following surgery. Herein, we report a case of sympathetic ophthalmia following blunt trauma to the phthisical eye along with the pathophysiology and management of such cases.

Classification of Non-Infectious and/or Immune Mediated Choroiditis: A Brief Overview of the Essentials

The choroid was poorly accessible to imaging investigation until the last decade of the last century. With the availability of more precise imaging methods such as indocyanine green angiography (ICGA) and, later, optical coherence tomography (OCT), enhanced depth OCT (EDI-OCT), and OCT angiography (OCTA), appraisal of choroidal inflammation has substantially gained in accuracy. This allowed to precisely determine which structures were touched in the different non-infectious choroiditis entities and made it possible to classify this group of diseases, ICGA signs, mainly hypofluorescent lesions, were identified and described. Previous publications have divided angiographic findings into two main sets of signs: (1) irregular “geographic” hypofluorescent areas corresponding to choriocapillaris non-perfusion and (2) round more regular, hypofluorescent dark dots more evenly distributed in the fundus corresponding to more deep choroidal stromal foci. These distinct findings allowed to subdivide and classify choroiditis into choriocapillaritis and stromal choroiditis. Additional signs were identified from EDI-OCT and OCTA examination supporting the classification of choroiditis into choriocapillaritis and stromal choroiditis. Results: Diseases involving principally the choriocapillaris included Multiple Evanescent White Dot Syndrome (MEWDS), Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE), Idiopathic Multifocal Choroiditis (MFC), and Serpiginous Choroiditis (SC) as well as mixed forms. Diseases primarily involving the choroidal stroma included HLA-A29 Birdshot Retinochoroiditis (BRC), Vogt-Koyanagi-Harada disease (VKH), Sympathetic Ophthalmia (SO), and Sarcoidosis chorioretinitis (SARC). Thanks to new imaging investigations of the choroid, it is now possible to classify and understand the diverse clinicopathological mechanisms in the group of non-infectious choroiditis entities.

Clinicomolecular Identification of Conserved and Individualized Features of Granulomatous Uveitis

Objective

To identify molecular features that distinguish individuals with shared clinical features of granulomatous uveitis.

Design

Cross-sectional, observational study.

Participants

Four eyes from patients with active granulomatous uveitis.

Methods

We performed single-cell RNA-sequencing with antigen-receptor sequence analysis to obtain an unbiased gene expression survey of ocular immune cells and identify clonally expanded lymphocytes.

Main Outcomes Measures

For each inflamed eye, we measured the proportion of distinct immune cell types, the amount of B or T cell clonal expansion, and the transcriptional profile of T and B cells.

Results

Each individual had robust clonal expansion arising from a single T or B cell lineage, suggesting distinct, antigen-driven pathogenic processes in each patient. This variability in clonal expansion was mirrored by individual variability in CD4 T cell populations, whereas ocular CD8 T cells and B cells were more transcriptionally similar between patients. Finally, ocular B cells displayed evidence of class-switching and plasmablast differentiation within the ocular microenvironment, providing additional support for antigen-driven immune responses in granulomatous uveitis.

Conclusions

Collectively, our study identified both conserved and individualized features of granulomatous uveitis, illuminating parallel pathophysiologic mechanisms, and suggesting that future personalized therapeutic approaches may be warranted.

An Atypical Presentation of Sympathetic Ophthalmia in an Intact Globe Following Mechanical Fall: A Case Report and Literature Review

PURPOSE

To describe an atypical case of sympathetic ophthalmia presenting after blunt trauma causing disinsertion of the iris in an intact globe.

METHODS

Case report.

RESULTS

A 71-year-old lady presented to the Emergency Department following a mechanical fall. On examination, she was noted to have periocular haematoma, subconjunctival haemorrhage, hyphaema, and vitreous haemorrhage in the left eye, but there was no evidence of globe rupture. The presenting visual acuity was 6/18. As the hyphaema and vitreous haemorrhage settled, a complete loss of the iris was noted with normal fundus. She was re-admitted a month later under the medical team with urinary tract infection and reduced vision in both eyes. On examination, there was mild conjunctival injection, keratic precipitates, anterior chamber flare, 180-degree posterior synechiae, and vitritis with no fundal view of the right eye. She was diagnosed with sympathetic ophthalmia and was treated with topical and systemic corticosteroid. Her vision improved gradually with treatment and was stable at 6/6 on the right (sympathising) eye and 6/9 on the left (excited) eye at final follow-up.

CONCLUSION

Sympathetic ophthalmia may result from non-penetrating ocular trauma. Comprehensive history of mechanism of injury and ophthalmic examination is essential so that prompt treatment can be given to improve the visual prognosis of affected patients.

Sympathetic ophthalmia: Report of a case series and comprehensive review of the literature

PURPOSE

To evaluate the factors related to sympathetic ophthalmia (SO) in a series of patients in our ophthalmology center and previously published cases.

METHODS

A retrospective and noncomparative review was performed on 16 patients with SO attending our ophthalmology center from 2013 to 2019. A total of 87 previously published cases of SO were identified by searching the Medline database from 2009 to 2019.

RESULTS

Sixteen patients were included in the analysis, and six cases were induced by transscleral cyclophotocoagulation (TCP). All patients had achieved controlled inflammation at their last follow-up visit. Thirteen patients (81.3%) had improved best-corrected visual acuity (BCVA). A review of the literature revealed 87 previously reported cases of SO. Shared clinical features and treatment outcomes were summarized.

CONCLUSION

Ocular therapies, including both penetrating ocular therapy and non-penetrating ocular intervention, have become increasingly prevalent risk factors for SO, and the latent period has increased compared to past reports. Visual prognosis with appropriate medical management is relatively good.

Exudative Retinal Detachment in Ocular Inflammatory Diseases: Risk and Predictive Factors

PURPOSE

This study evaluated the risk and risk factors for exudative retinal detachment (ERD) in ocular inflammatory diseases.

DESIGN

Retrospective cohort study.

METHODS

Patients with noninfectious ocular inflammation had been followed longitudinally between 1978 and 2007 at 4 US subspecialty uveitis centers. The main outcome measurements were occurrences of ERD and predictive factors.

RESULTS

A total of 176 of 14,612 eyes with ocular inflammation presented with ERD. Among uveitis cases, Vogt-Koyanagi-Harada syndrome (VKH) (odds ratio [OR] = 109), undifferentiated choroiditis (OR = 9.18), sympathetic ophthalmia (OR = 8.43), primary or secondary panuveitis (OR = 7.09), multifocal choroiditis with panuveitis (OR = 4.51), and "other" forms of posterior uveitis (OR = 16.9) were associated with a higher prevalence of ERD. Among the 9,209 uveitic or scleritic eyes initially free of ERD and followed, 137 incident ERD cases were observed over 28,949 eye-years at risk (incidence rate = 0.47% [0.40%-0.56%/eye-year]). VKH (HR = 13.2), sympathetic ophthalmia (HR = 5.82), undifferentiated choroiditis (HR = 6.03), primary or secondary panuveitis (HR = 4.21), and rheumatoid arthritis (HR = 3.30) were significantly associated with incident ERD. A significant dose-response relationship with the prevalence and incidence of ERD were observed for AC cells and vitreous cell activity. African Americans had significantly higher prevalence and incidence of ERD.

CONCLUSIONS

Other ocular inflammatory conditions in addition to VKH syndrome and posterior scleritis were associated with increased risk of ERD, indicating that ERD does not necessarily dictate a diagnosis of VKH or posterior scleritis. In addition, the relationship between ERD and inflammatory severity factors implies that inflammation is a key predictive factor associated with developing ERD and requires early and vigorous control.

Sympathetic Ophthalmia - a Contribution to Immunology, Clinic and Current Imaging

BACKGROUND

Sympathetic ophthalmia (SO) is a rare inflammation of an operated or injured eye that spreads to the fellow eye. It is typically a bilateral granulomatous panuveitis. The traumatized eye is referred to as inciting eye and the fellow eye as sympathizing eye. The pathophysiology of the disease is not entirely understood, but there is strong evidence of an autoimmune genesis.

PATIENTS/MATERIAL AND METHODS

A selective literature search on epidemiology, immunology, clinical features and risk factors of SO was carried out. In addition, our own experience using multimodal imaging for this clinical entity was introduced.

RESULTS

In the literature, the incidence after traumatic eye injuries is 0.1 - 3% and approximately 0.01% after intraocular surgery. Among the iatrogenic causes, vitreoretinal surgery has the highest rate of SO, presumably due to disruption of the blood-retinal barrier and involvement of retinal and choroidal tissue, which are susceptible to anterior traction, phthisis and chronic inflammation. In 90% of patients, the disease develops within a year following the eliciting event and is associated with a potentially bilateral risk of blindness. Typical symptoms include bilateral visual impairment with photophobia, dull pain and photopsia. The spectrum of clinical manifestations ranges from granulomatous anterior uveitis and vitritis, to choroiditis, serous retinal detachment and Dalen-Fuchs nodules in the context of posterior involvement. The diagnosis of SO is generally based on clinical presentation and is supported by imaging methods. These primarily comprise fluorescein and indocyanine green angiography, which are increasingly being supplemented by non-invasive methods such as optical coherence tomography. They can provide important information for assessment of severity, differential diagnosis as well as for disease monitoring. The differential diagnosis includes i. a. Vogt-Koyanagi-Harada syndrome, ocular sarcoidosis and the rare phacoanaphylactic endophthalmitis. Immediate systemic high-dose steroid therapy is used as initial treatment. The course of the disease is often relapsing to chronic progressive. Immunomodulators such as ciclosporine A, azathioprine, cyclophosphamide, mycophenolate mofetil, and biologics are increasingly being used and contribute to the significantly better prognosis of the disease. Generally, SO can be triggered by any kind of intraocular intervention.

CONCLUSION

SO remains a threatening clinical diagnosis that poses diagnostic and therapeutic challenges. It can be triggered post-traumatic, but also any intraocular surgery. This should be taken into account when assessing the indication for intraocular eye surgery, especially in eyes with reduced visual outcome.

Posterior segment complications following glaucoma surgeries

The present review describes the posterior segment complications following surgical management of glaucoma. Although the majority of glaucoma cases are managed medically, still a large number of patients may require surgery. Moreover, with the advent of newer surgical techniques and adjuncts, encountering retinal complications post-surgery is not uncommon. The incidence, signs, management, and prognosis of common complications such as anesthesia-related retinal toxicity, vitreous loss, suprachoroidal hemorrhage, serous choroidal detachment, hypotonic maculopathy, vitreous hemorrhage, retinal detachment and endophthalmitis will be discussed in detail. Awareness of these complications is necessary as their proper and timely management can save vision in an already compromised eye.

Sympathetic ophthalmitis after scleral perforation during strabismus surgery

We report the case of a 24-year-old woman who experienced sympathetic ophthalmitis after scleral perforation during strabismus surgery. She presented postoperatively with distorted vision and was successfully treated with intravenous and oral steroids.

A rare entity: Sympathetic ophthalmia presumably after blunt trauma to the phthisical eye and optical coherence tomography angiography metrics to monitor response to treatment

A blunt trauma to a phthisical eye may elicit sympathetic ophthalmia. Non invasive imaging such as use of optical coherence tomography and angiography metrics of the retinal and choroidal vasculature can help monitor response to the treatment.

Features of ectopic lymphoid-like structures in human uveitis

Persistent non-infectious uveitis has a significant morbidity, but the extent to which this is accompanied by inflammation driven remodelling of the tissue is unclear. To address this question, we studied a series of samples selected from two ocular tissue repositories and identified 15 samples with focal infiltration. Eleven of fifteen contained lymphocytes, both B cells (CD20 positive) and T cells (CD3 positive). In 20% of the samples there was evidence of ectopic lymphoid like structures with focal aggregations of B cells and T cells, segregated into anatomically different adjacent zones. To investigate inflammation in the tissue, an analysis of 520 immune relevant transcripts was carried out and 24 genes were differentially upregulated, compared with control tissue. Two of these (CD14 and fibronectin) were increased in ocular inflammation compared to control immune tissue (tonsil). We demonstrate that in a significant minority of patients, chronic persistent uveitis leads to dysregulation of ocular immune surveillance, characterized by the development of areas of local ectopic lymphoid like structures, which may be a target for therapeutic intervention directed at antibody producing cells.

•

Active inflammation continues in cases of persistent uveitis.

•

Some patients develop ectopic lymphoid-like structure.

•

In these cases targeting B cells may be beneficial.

Choroidal Structural Changes in Sympathetic Ophthalmia on Swept-Source Optical Coherence Tomography

Purpose: To analyze choroidal angioarchitecture in sympathetic ophthalmia (SO) using swept-source optical coherence tomography (SS-OCT) images.Methods: Case-control study of six patients with SO. Qualitative changes and quantitative parameters, including choroidal thickness (CT) and choroidal vascularity index (CVI), were analyzed.Results: Qualitative findings in the acute phase of SO on SS-OCT included retinal serous detachment with hyperreflective septa, choroidal folds, alterations in angioarchitecture with loss of vascular lacunae, and Dalen-Fuchs nodules. There was significantly higher CT in SO (284.05 ± 24.12 µm) compared to healthy controls (229.57 ± 46.67 µm, p = 0.04) and also increased CVI in SO (62.06 ± 2.07% vs 56.79 ± 3.15%, p = 0.006).Conclusions: CVI was significantly increased in SO, representing a novel noninvasive biomarker of disease activity. SS-OCT provides a useful qualitative and quantitative parameter, which can be potentially explored in the diagnosis and monitoring of patients with SO.

Outcomes of ocular evisceration and enucleation in the British Armed Forces from Iraq and Afghanistan

BACKGROUND/OBJECTIVES

To evaluate outcomes from all British military patients who underwent eye removal during the Iraq and Afghanistan wars.

SUBJECTS/METHODS

Retrospective case note review of all patients (n = 19) who had undergone either evisceration or enucleation, on a database of all military patients repatriated to the Royal Centre for Defence Medicine, Birmingham.

RESULTS

Twenty eye removals were performed on 19 patients, of which 14 (70%) were eviscerations and 6 (30%) were enucleations. Orbital wall fractures were seen in 12 (61%) patients, with orbital floor fractures being the most common. The eye removal was a primary procedure in five of fourteen eviscerations, and five of six enucleations. Complications were seen after four (28.6%) eviscerations patients and two (33.3%) enucleations. Postoperative pain was problematic after three (21.4%) eviscerations but no enucleations. Orbital implants were placed during three of the five primary enucleations, with good outcomes in two. One patient however required implant retrieval and wound washout due to a high risk of infection and communication with the intra-cranial space.

CONCLUSIONS

Evisceration and enucleation are both viable options in the management of severe ocular trauma in military patients. Evisceration and enucleation have similar complication rates and outcomes, and both have low rates of sympathetic ophthalmia. Primary orbital implants can be at high risk in cases with orbital roof fracture, but can provide good outcomes in select patients.

Sympathetic Ophthalmia after Vitreoretinal Surgeries: Incidence, Clinical Presentations and Outcomes of a Rare Disease

Aim: To evaluate clinical presentation, course and outcomes in patients without a history of penetrating ocular trauma who developed Sympathetic Ophthalmia (SO) following vitreoretinal surgeries Methods: Retrospective review of clinical records of all patients diagnosed and treated as S.O was done . All cases without a previous history of trauma were included and were analyzed with respect to clinical presentations, anatomic and visual outcomes. Results: 175 cases of sympathetic ophthalmia were diagnosed and treated till June 2017. 16 of these cases had undergone a pars plana vitrecomy (PPV) in the past and had no history of prior ocular trauma. SO after vitreoetinal surgeries accounted for 9.14 percent of all cases of SO .In the same duration, till 2017,a total 41365 PPV were done. Thus 0.038 percent of PPV cases developed a SO . 10 patients were males and 6 were females. The median age at presentation was 45.7 years. The time interval from surgery to diagnosis of sympathetic ophthalmia ranged from 22 days to 4 years after undergoing a surgery. The mean visual acuity in the sympathizing eye was 1.26 logMAR (snellens equivalent of 20/320) which improved to 0.62 logMAR(snellens equivalent of 20/80) after treatment. The most common anterior segment finding was non granulomatous anterior uveitis, seen in 8 cases (50%) while neurosensory detachments were the most common posterior segment presentation (10 cases, 62.5%).12 patients had undergone more than 1 surgery (mean number of surgeries was 1.88). 10 patients had undergone a sutureless PPV (6 cases of 23 gauge and 4 cases of 25 gauge vitrectomy) while 4 patients had undergone a 20 gauge vitrectomy where all sclerotomies were sutured after surgery All patients were treated with systemic steroids and immunosuppresants and 15 out of 16 patients showed significant improvement in the final visual acuity in the sympathizing eye Conclusions: Sympathetic ophthalmia after vitreoretinal surgeries is a rare but potentially sight threatening disease occurring in 0.038 percent of all cases of Pars Plana Vitrectomy. Presence of inflammation in the fellow eye after a vitreoretinal surgery in the other eye should alert the surgeon to possibility of sympathetic ophthalmia.

Effective treatment of refractory sympathetic ophthalmia with glaucoma using adalimumab

Purpose

Sympathetic ophthalmia (SO) is an autoimmune, bilateral, granulomatous panuveitis, which occurs following penetrating eye injury or eye surgery. We report two cases of refractory SO in patients with a history of trabeculectomy, which were treated effectively with adalimumab.

Observations

Case 1: A 69-year-old male with a history of trabeculectomy for rubeotic glaucoma of the right eye, secondary to diabetic retinopathy 8 years prior, presented with a decrease in visual acuity of the left eye due to SO. After two rounds of pulse corticosteroid therapy (intravenous infusion of 1 g methylprednisolone/day for 3 days), serous retinal detachment (SRD) was resolved. As oral prednisolone was tapered to avoid deterioration of the diabetes mellitus, we shifted to other immunosuppressive therapies to control inflammation. Methotrexate 6mg/week (0.1 mg/kg) was introduced first, but was discontinued owing to side effects. After 6 months of cyclosporine 100 mg/day (1.5 mg/kg, max. dose 2.3 mg/kg), the SRD relapsed. Adalimumab was then introduced, which led to remission of SRD, and inflammation was controlled for 7 months.

Case 2: A 43-year-old male, with a history of trabeculectomy for primary open-angle glaucoma of the right eye 4 years prior, presented with blurred vision in the right eye. Optical coherence tomography revealed SRD and choroidal thickening in both eyes. Pulse corticosteroid therapy (intravenous infusion of 1 g methylprednisolone/day for 3 days) was initiated, followed by oral prednisolone. SRD gradually improved, but it did not resolve completely. Given the severe visual loss the patient had experienced due to the primary open-angle glaucoma, oral prednisolone was tapered quickly to avoid steroid-induced intraocular pressure (IOP) elevation. Cyclosporine 125 mg/day (1.8 mg/kg, max. dose 2.1 mg/day) was introduced first, but was later discontinued because of side effects. Adalimumab was then administered, causing the SRD to disappear; and IOP was well-controlled. After the introduction of adalimumab, control of intraocular inflammation was achieved and IOP remained within the target range for 7 months.

Conclusions and importance

SO requires long-term immunosuppressive treatment. Adalimumab is an effective treatment in cases of steroid or immunosuppressant refractory SO, particularly for glaucoma patients, in whom long-term steroid therapy should be avoided.

The long-term monitoring of sympathetic ophthalmia in the diagnostic and terapeutic view. Review Department of Ophthalmology

AIM

To evaluate options of diagnostic and therapeutic procedures of sympathetic ophthalmia (SO) compared with literature data. Backgroud: SO is an ocular autoimmune disease. It is characterized by disbalance in the imunoregulatory T-subsets within cell mediated immune response.

METHODS

File examination of SO by evaluation humoral and cellular immunity was ranked nukleolar test (NT). It evaulates the current status of lymphocyte activation based on the nucleolar morphology and RNA transcription aktivity. The classical histological examination was supported by immunohistochemical analysis of lymphocytic subpopulations in the eyeball enucleated for. SO in one case.

MATERIAL

Five boys and men overall were monitored and treated in two studies from 1979 to 1994 and from 1999 to 2017 with SO In four cases it was subsequent after penetrating injuries and once after lensectomy with vitrectomy. The age of patients in the time of onset of SO was between 4 and 24 years (average 12 years). The time interval between insult and onset of SO varied between 10 days and 3 months (average 1.7 months). The relaps of disease appeared in the all cases in the time interval from 3 months to 38 years (average 15 years). Another two patients with SO were examined only in consultation: 16 years old boy with relaps of SO after cataract extraction and 71 years old women with SO subsequent after lensectomy and vitrectomy. There was examined and compared group of 19 patients with other types of uveitis in the same time. The lens-associated uveitis were caused after ocular contusion and penetrating eye injury in 16 patients (13 male patients). In another three cases (young women) with uveitid underlined by II. or III. type of hypersenzitivity the enucleation of dolorous eyeball calmed down the secondary uveitis on their second eye without any change of immunosupressive treatment and without change in NT.

RESULTS

There were changes in the complex immunological laboratory tests results in the SO cases in the counts of activated lymphocytes in the peripheral blood. The count of activated lymphocytes was increased in SO cases unlike in lens-associated uveitis. There was detected in NT statistically significant difference (p = 0,0134) between the two groups of uveitis. The histological examination (5 eyes with SO and 7 eyes without sympathetic uveitis) confirmed the diagnoses, supporting basically the clinical diagnosis. The immunohistochemical examination corfirmed the presence of populations of T-lymphocytes, macrophages and also B-lymphocytes. A basis of immunosuppressive therapy was the combination of prednisone and azathioprin at the first time. Effective therapy featured cyklosporine later.

CONCLUSION

The nucleolar test of lymphocytes draws attention of their up-to-day increased activity without the diferentiation of subpopulations and their absolute number increase related to the current activation of type IV. hypersensitivity (cell-mediated) in uveitis mechanism. The immunosupressive therapy calmes down this activation predominantly in SO, but also in other case sof uveitis with different types of hypersensivity. The immunohistochemical examination illustrates different presence of lymphocytic types according to the stage of SO.

Visual and ocular morbidity in severe open-globe injuries presenting to a regional eye centre in New Zealand

IMPORTANCE

Open-globe injuries (OGI) are a leading cause of monocular blindness world-wide with considerable cost to the individual and society.

BACKGROUND

To characterize the epidemiology, severity and outcomes of OGI treated at a major ophthalmology centre in New Zealand.

DESIGN

Retrospective study.

PARTICIPANTS

A total of 385 eyes of 381 patients over a 10-year period.

METHODS

Eligible patients were identified using diagnosis and surgery codes on hospital discharge summaries. Clinical notes were reviewed to determine patient demographics, injury details, treatments and outcomes.

MAIN OUTCOME MEASURES

Complications of injury, visual acuity at 3 months and final follow-up, and final status of the eye.

RESULTS

The estimated annual incidence of OGI was 2.8 per 100 000. Working-age males predominated but age at injury ranged from 9 months to 90 years. Maori and Pacific peoples were over-represented. Injuries were severe with 58.7% presenting with vision of hand movements or worse. Penetrating injuries (56.4%) were most common, followed by globe ruptures (35.6%). Major complications included retinal detachment (15.8%), enucleation/evisceration (9.1%), phthisis bulbi (9.9%), endophthalmitis (2.6%) and sympathetic ophthalmia (0.26%). Despite the injury severity, 46% of eyes achieved final BCVA of ≥6/12. The Ocular Trauma Score (OTS) was a useful prognostic tool for stratifying severity of injury and predicting visual outcome (Fisher's exact test P < 0.001).

CONCLUSIONS AND RELEVANCE

The incidence and severity of OGI in NZ are comparable to global statistics. Surgical repair can effectively recover vision, predicted well by the OTS. We identified at-risk groups to target with education and prevention strategies.

Blindness after facial trauma: epidemiology, incidence and risk factors: a 27-year cohort study of 5708 patients

OBJECTIVES

This was a 27-year study of a cohort of 5708 patients who had sustained maxillofacial fractures. Our purpose was to present the etiology, mechanism of trauma, site, and concomitant injuries that led to visual loss. We hypothesize that fractures caused by high-energy impact of the midface may be associated with blindness. A discussion of the treatment approaches is also included.

STUDY DESIGN

The study included 5708 patients who had sustained a maxillofacial fracture during the years 1985-2012. Patients' records were reviewed for gender, age, fracture site, etiology of trauma, concomitant injuries, method of treatment, length of hospital stay, and cause of blindness. The relationship of the above variables to blindness was investigated.

RESULTS

The incidence of loss of vision was 0.34%. A very strong association between firearm injuries and blindness was observed (P < .001). These patients spent much longer time in hospital (P < .01) and suffered serious concomitant injuries involving the brain.

CONCLUSIONS

Retrobullbar hemorrhage should be treated with lateral canthotomy, whereas in traumatic optic neuropathy, observation seems to be the safest thing to do. In patients with penetrating injuries of the globe, the immediate involvement of an ophthalmic surgeon is of paramount importance.

Postsurgical sympathetic ophthalmia: retrospective analysis of a rare entity

PURPOSE

To describe clinical manifestations, management and visual outcome in postsurgical sympathetic ophthalmia (SO).

METHODS

Retrospective study.

RESULTS

Mean age of the patients was 41.1 years, and males were affected 1.8 times than the female. Vitrectomy and scleral buckling were the most common inciting surgeries followed by cataract surgery. Among 10 eyes with anterior uveitis, mutton-fat keratic precipitate was seen in only two eyes. Mean follow-up duration was 1556.50 ± 1470.75 days. Vision significantly improved in 11 patients (78.6%; p = 0.005).

CONCLUSION

Postsurgical SO is a rare entity, but it is a bilateral blinding disease and SO following surgical intervention can have variable presentations. Rapid, effective management of postsurgical sympathetic ophthalmia can give improved visual outcomes.

AN ATYPICAL CASE OF SYMPATHETIC OPHTHALMIA AFTER LIMBAL CORNEAL LACERATION

In this study, we report a case of bilateral exudative retinal detachment due to sympathetic ophthalmia after successful limbal corneal laceration repair. Steroids remain mainstay management in controlling this disorder; however, there is no role of prophylactic steroid to prevent it. On the contrary, steroid use may alter the course of the disease.

Background/Purpose:

To report a case of atypical sympathetic ophthalmia after limbal corneal laceration.

Methods and Results:

An 11-year-old child had a successful left eye corneal laceration repair at the temporal limbus with excision of exposed nonnecrotic iris tissue, resulting in good visual acuity of 20/80 and 20/25 on postoperative Days 1 and 7, respectively. The patient was prescribed 1 mg/kg oral prednisolone in a tapering dose as prophylaxis. On postoperative Day 21, the patient presented with acute onset decreased vision in both eyes. Visual acuity was counting fingers 3 feet in both eyes. On examination, anterior segment examination was quiet without any inflammation, anterior vitreous face showed 1+ cells, and dilated funduscopy revealed bilateral symmetrical serous retinal detachments along the posterior pole. Optical coherence tomography demonstrated separation and elevation of inner neurosensory layers from the outer segment marking presence of hyperreflective material along with subretinal fluid between detached surfaces. There was stippled hyperfluorescence along the posterior pole as seen in fluorescein angiography. With a diagnosis of sympathetic ophthalmia confirmed, oral prednisolone (2 mg/kg body weight) was instituted after which, there was gradual decrease in macular elevation with corresponding improvement in visual acuity with no recurrence for the last 6 months.

Conclusion:

To our knowledge, this is the first reported instance of an atypical presentation of sympathetic ophthalmia, and antecedent corticosteroid therapy would have mitigated robust anterior segment findings usually associated with the condition.

Characteristics of Sympathetic Ophthalmia in a Single International Center

AIM

To report the main features of sympathetic ophthalmia in a referral ophthalmology center.

METHODS

Retrospective clinical study. We reviewed clinical records of patients with diagnosis of sympathetic ophthalmia attending the Uveitis Department from 2007 to 2013. Patients were selected by clinical criteria. Descriptive statistics were used to assess variables.

RESULTS

Twenty patients were included for analysis, 13 males and 7 females. Mean follow up was 1 year. The median age of presentation was 50 years. Fifty percent had history of ocular trauma and 50% had history of intraocular surgery, of which 40% underwent phacoemulsification. The time between injury and onset of symptoms ranged from 1 to 456 months. Most common ocular manifestations were mutton fat keratic precipitates and anterior chamber inflammation. All patients received oral prednisone as single or combined therapy. Sixty percent of the sympathizing eyes improved two or more lines of vision and 20% lost two or more lines of vision.

CONCLUSION

This report from a single center adds to the body of literature of sympathetic ophthalmia occurring in a specific population. Our data found a high proportion of patients with sympathetic ophthalmia after phacoemulsification.

Molecular Signals Involved in Human B Cell Migration into the Retina: In Vitro Investigation of ICAM-1, VCAM-1, and CXCL13

PURPOSE

B cells participate in diverse retinal immunopathologies. Endothelial adhesion molecules and chemokines direct leukocyte trafficking. We examined the involvement of three molecular signals in retinal transendothelial migration of human B cells: ICAM-1, VCAM-1, and CXCL13.

METHODS

Peripheral blood B cells were isolated by negative selection. Migration was studied in transwells populated with human retinal endothelial monolayers, using antibody to block ICAM-1 or VCAM-1. Retinal expression of CXCL13 was investigated.

RESULTS

B cells crossed retinal endothelium. ICAM-1 blockade significantly reduced migration when results for all subjects were combined, and for a majority when results were analyzed by individual. This effect was irrespective of the presence or absence of CXCL13, although CXCL13 increased migration. CXCL13 was detected in neural retina and retinal pigment epithelium. Endothelial cells of some retinal vessels presented CXCL13 protein.

CONCLUSION

ICAM-1 blockade may be an effective treatment in some patients with retinal diseases that involve B cells.

Involvement of B cells in non-infectious uveitis

Non-infectious uveitis-or intraocular inflammatory disease-causes substantial visual morbidity and reduced quality of life amongst affected individuals. To date, research of pathogenic mechanisms has largely been focused on processes involving T lymphocyte and/or myeloid leukocyte populations. Involvement of B lymphocytes has received relatively little attention. In contrast, B-cell pathobiology is a major field within general immunological research, and large clinical trials have showed that treatments targeting B cells are highly effective for multiple systemic inflammatory diseases. B cells, including the terminally differentiated plasma cell that produces antibody, are found in the human eye in different forms of non-infectious uveitis; in some cases, these cells outnumber other leukocyte subsets. Recent case reports and small case series suggest that B-cell blockade may be therapeutic for patients with non-infectious uveitis. As well as secretion of antibody, B cells may promote intraocular inflammation by presentation of antigen to T cells, production of multiple inflammatory cytokines and support of T-cell survival. B cells may also perform various immunomodulatory activities within the eye. This translational review summarizes the evidence for B-cell involvement in non-infectious uveitis, and considers the potential contributions of B cells to the development and control of the disease. Manipulations of B cells and/or their products are promising new approaches to the treatment of non-infectious uveitis.

SYMPATHETIC OPHTHALMIA: Clinicopathologic Correlation in a Consecutive Case Series

PURPOSE

To correlate the clinical course of sympathetic ophthalmia with the histological and immunohistochemical characteristics of the enucleated inciting eye.

METHODS

A consecutive case series with baseline clinical features and subsequent histopathologic findings.

RESULTS

Evaluation of the 16 enucleated inciting eyes (blind and painful) disclosed that 9 of the 16 had typical histology, fulfilling the criteria for sympathetic ophthalmia of diffuse granulomatous inflammation. Among the 16, 11 sustained previous penetrating trauma, 4 underwent previous eye surgery, and 1 patient presented with an unknown etiology. Patients with atypical histology (7 of 7) were taking corticosteroids at the time of enucleation. Only 2 of 9 patients with typical histology were taking corticosteroids at the time of enucleation. At 6 months after enucleation of the inciting eye, 4 of the 7 patients with atypical histology had a visual acuity of ≥20/40 compared with 8 of 8 patients (100%) with typical histology. On a 4-point scale (0-3+), the choroidal infiltrate of the 9 histopathologically typical eyes showed an average of 2.5+ CD68 (macrophages), 2.5+ CD20 (B cells), and 1.5+ CD3 (T cells).

CONCLUSION

Histopathologic findings had minimal correlation with the clinical course of sympathetic ophthalmia. Corticosteroid treatment before enucleation may influence the pathologic confirmation of sympathetic ophthalmia. The predominance of B lymphocytes and macrophages over T lymphocytes may represent different stages of the disease process.

Enucleation and evisceration at a tertiary care hospital in a developing country

Background

To analyze the demographics, indications, and surgical outcomes of anophthalmic surgery (enucleation and evisceration) at Jordan University Hospital during a 5-year period.

Methods

We conducted a retrospective chart review of patients who had undergone evisceration or enucleation between August 2006 and June 2011. The data collected included age at time of surgery, sex, affected eye, surgical indication, implant size, and postoperative complications.

Results

Anophthalmic surgery was performed for 68 eyes of 67 patients during the study period (42 (62 %) eviscerations and 26 (38 %) enucleations). Forty-three patients (64 %) were men, and 40 (59 %) eyes were right eyes. Trauma was the leading cause for anophthalmic surgery in 40 % of cases followed by a blind painful eye secondary to glaucoma (19 %) in the enucleation group and endophthalmitis (28.6 %) in the evisceration group. The most common anophthalmic surgery complication was wound dehiscence in 11.5 % of patients in the enucleation and 9.5 % in the evisceration groups. The mean and median sizes of the implants for evisceration were 16.6 and 18.0 mm, respectively; for enucleation, both were 20 mm.

Conclusions

Evisceration was the preferred anophthalmic surgery in our series unless contraindicated. Trauma was the most common predisposing factor for evisceration and enucleation in our tertiary care center followed by blind painful eyes and endophthalmitis. The most common complication was wound dehiscence in both groups.

Bilateral hearing impairment as the initial symptom of sympathetic ophthalmia

IMPORTANCE

Sympathetic ophthalmia (SO), a rare bilateral panuveitis following penetrating ocular trauma or ocular surgery to one eye, shares a strikingly similar ocular pathology to that of Vogt-Koyanagi-Harada disease (VKH). Audiovestibular dysfunction is a major extraocular manifestation of VKH; however, to date, only a few cases of sympathetic ophthalmia associated with hearing loss have been reported from ophthalmologists, but not otolaryngologists. Accordingly, little is known about the audiovestibular findings in patients with SO. We herein present two cases of SO with preceding bilateral hearing loss.

OBSERVATIONS

The patient in Case 1, an 80-year-old female, experienced acute bilateral hearing loss. Five days after the onset of hearing loss, she presented with sudden bilateral blurred vision. In Case 2, a 32-year-old female noticed acute bilateral hearing loss and also experienced acute bilateral blurred vision the subsequent day. Patient 1 had a history of a penetrating injury to the right eye 25 days before the onset of hearing loss, while patient 2 had previously undergone right vitreous surgery twice for the treatment of a myopic macular hole and retinal detachment 36 and 43 days prior to the current symptom onset. Both cases were diagnosed as SO based on ocular findings of bilateral panuveitis and the history of ocular insult. Patient 1 carried HLA-DR4, HLA-DR15, HLA-A33, HLA-A24, HLA-B44 and HLA-B52, and patient 2 carried HLA-DR4. Audiograms showed bilateral mild to moderate sensorineural hearing loss in both cases, with normal auditory brainstem responses and deteriorated distortion product otoacoustic emission amplitudes. In addition, the significant recruitment phenomenon observed in case 1 suggested a cochlear origin of the hearing loss. Both patients received corticosteroid therapy, and the cochlear signs and symptoms recovered within one month.

CONCLUSIONS AND RELEVANCE

This is the first report to describe the comprehensive audiovestibular findings in patients with SO. In the present study, acute bilateral hearing loss developed a couple of days prior to the onset of bilateral visual loss and auditory examinations suggested a cochlear etiology in both cases.
