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.

Surgical Intervention in Inciting Eyes of Patients with Sympathetic Ophthalmia: A Case Series and Review of Literature.

Purpose: To analyze the outcomes of surgical procedures on inciting eye of patients with Sympathetic ophthalmia (SO). Methods: Retrospective study of patients with SO who underwent surgical procedures on inciting eyes between January 2000 and December 2015. Outcome measures included flare up of inflammation in either eye and change in visual acuity in the inciting eye. Results: Four SO patients underwent surgeries in their inciting eyes after adequate control of inflammation. Surgical procedures included penetrating keratoplasty, glaucoma drainage device implantation, pars plana vitrectomy, and silicon oil removal. Keratoplasty, glaucoma surgery, and silicon oil removal were well tolerated, with no flare up of disease. The patient who underwent pars plana vitrectomy, however, had a poor outcome. Conclusions: Surgical intervention in inciting eyes of patients with SO, after being adequately treated with oral steroids and immunosuppression, is a viable option for improving anatomic and functional outcomes in these eyes.

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.

[Sympathetic ophthalmia following repeated pars plana vitrectomy : Clinical findings and spectral domain OCT follow-up]. / Sympathische Ophthalmie nach zweimaliger Pars-plana-Vitrektomie : Klinische Befunde und Spectralis-OCT-Verlauf.

Sympathetic ophthalmia is a rare form of bilateral granulomatous panuveitis, occurring after penetrating trauma. Hitherto, sympathetic ophthalmia after vitrectomy has only occasionally been described in the literature. This case report presents a female patient with sympathetic ophthalmia after repeated pars plana vitrectomy on the basis of clinical findings and follow-up with fluorescein angiography, spectral domain OCT, and histopathology.

Evisceration for the management of ocular trauma.

Despite the eye being surrounded by orbital bones and protective mechanisms such as the blink reflex, it is vulnerable to trauma. The two key issues to consider when presented with a case of ocular trauma are the visual potential of the eye and the risk of sympathetic ophthalmia. The Ocular Trauma Score can be used to assess the visual potential of the injured eye. Surgical management may be either repair or removal of the eye (evisceration or enucleation). Herein we describe a case of ocular trauma and the decision-making process in the management of the injury.

Histopathological changes of cornea in long-term sympathetic ophthalmitis.

PURPOSE: To report the histopathological changes occurring in the cornea in sympathetic ophthalmitis. METHODS: Observational case series of 3 patients with sympathetic ophthalmitis who were treated with penetrating keratoplasty. We report the histopathological features of the cornea. RESULTS: In all 3 cases, the epithelium was edematous and bullous with extensive loss of the Bowman layer and calcification of the superficial stroma in all the 3 eyes. The deep stroma was unremarkable in appearance. Descemet membrane showed thickening in 2 of the corneas with nodular excrescences and folds noted in 1 of the specimens. The endothelium was attenuated with some residual cells containing pigment granules in 1 case. CONCLUSIONS: Endothelial loss and development of bullous keratopathy associated with band keratopathy are predominate histopathological features of the cornea. These changes are nonspecific and reflect a chronic anterior uveitis.

Sympathetic ophthalmia following vitrectomy for endophthalmitis after intravitreal bevacizumab.

PURPOSE: To describe a case of sympathetic ophthalmia following vitrectomy for endophthalmitis after an intravitreal injection of bevacizumab. DESIGN: Retrospective case report. METHODS: An 84-year-old male developed sympathetic ophthalmia 4 months after vitrectomy for endophthalmitis following an intravitreal injection. The inciting blind eye was enucleated. RESULTS: Histopathology demonstrated sympathetic ophthalmia and phacoanaphylactic endophthalmitis. Visual acuity improved from 20/200 to 20/30 in the sympathizing eye with a combination of oral prednisone and azathioprine. CONCLUSIONS: Sympathetic ophthalmia can develop following exogenous endophthalmitis but has a good visual prognosis with appropriate treatment.

Penetrating keratoplasty for the exciting eye in sympathetic ophthalmia.

PURPOSE: We report a case of sympathetic ophthalmitis where we performed penetrating keratoplasty on the exciting eye many years after the initial injury. METHODS: Case report. RESULTS: After penetrating keratoplasty, the patient achieved vision of 3/60 from preoperative perception of light. CONCLUSIONS: Our experience shows that penetrating keratoplasty can restore useful vision in the previously injured exciting eye in sympathetic ophthalmitis. This case highlights a unique example where the inciting eye has ultimately become the eye with the better vision as the damage was limited.

Cataract surgery in sympathetic ophthalmia.

PURPOSE: To analyze the results of cataract surgery in patients with sympathetic ophthalmia. SETTING: Sankara Nethralaya, Medical Research Foundation, Chennai, India. METHODS: This study comprised 66 patients (132 eyes) with sympathetic ophthalmia seen at the uveitis referral clinic between January 1990 and July 2001; 42 eyes (31.8%) had cataract. Cataract surgery was performed in 17 sympathizing eyes and 1 exciting eye (17 patients). The records of these 18 eyes were retrospectively analyzed. Three eyes had extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation, 6 eyes had ECCE without IOL implantation, and 9 eyes had phacoemulsification with IOL implantation. The mean follow-up was 28.7 months (range 3 to 60 months). RESULTS: The causes of sympathetic ophthalmia were penetrating trauma (n = 8 eyes), ocular surgery (n = 6), perforated corneal ulcer (n = 2), and cyclocryotherapy (n = 1). The most common cataract type, present in 7 eyes (38.8%), was mixed (posterior subcapsular and posterior polar). Visual acuity improved after surgery in 13 eyes (72.2%). The main factors impairing visual recovery were submacular scar and optic atrophy, which were sequelae of the sympathetic ophthalmia. Posterior capsule opacification was noted in 14 eyes (77.7%); it was visually significant in 6 eyes. There was no significant difference in postoperative inflammation or disease reactivation between the 3 types of surgery. CONCLUSIONS: Cataract extraction in cases of sympathetic ophthalmia can be safely and successfully performed with vigilant preoperative and postoperative control of inflammation, careful surgical planning, and meticulous surgical technique. The final visual outcome, however, depends on the posterior segment complications of the disease.

Oftalmía simpática postvitrectomía tras traumatismo y taponamiento con perfluorocarbono líquido / Sympathetic ophthalmia post-vitrectomy following trauma and perfluorocarbon liquid tamponade

Caso clínico: Se describe un caso de oftalmía simpática (OS) desarrollado tras un traumatismo contuso tratado mediante vitrectomía (que se complicó con una hemorragia supracoroidea masiva) y taponamiento con perfluorocarbono líquido (PFCL). Discusión: La presentación de OS en un paciente vitrectomizado tras un traumatismo ocular contuso grave con taponamiento intra-ocular prolongado con PFCL permitiría plantear la hipótesis de que la reacción inflamatoria crónica producida por estos compuestos podría haber colaborado en el desarrollo de la OS. Sin embargo, existen otros posibles factores causales como el propio traumatismo, la vitrectomía en sí o el desprendimiento de coroides con posible incarceración de tejido uveal en las incisiones(AU)

Case report: We report a case of sympathetic ophthalmia (SO) developed after blunt trauma and vitrectomy (complicated with a massive suprachoroidal hemorrhage) using perfluorocarbon liquid (PFCL) for tamponade. Discussion: The presentation of SO in a vitrectomized patient after severe blunt trauma with extended intra-ocular tamponade with PFCL could support the hypothesis that chronic inflammation caused by PFCL could have contributed to the development of SO. Nevertheless, there are other possible causal factors such as the trauma, the vitrectomy itself or the choroidal detachment with possible uveal incarceration at wound sites(AU)

Trata-se do primeiro caso, de nosso conhecimento, de oftalmia simpática pós-vitrectomia via pars plana relatado na literatura nacional

Surgical treatment of sympathetic ophthalmia.

We report the case of a 12-year-old girl who was hospitalized for bilateral uveitis that occurred 2 years after a penetrating injury of the left eye. On admission, all clinical signs of sympathetic ophthalmia were present with visual function reduced to light perception and intact projection in the right eye and light perception without intact projection in the left. Ultrasonography confirmed that the retina was in its proper place in both eyes. Since abrasion of the corneal epithelium and decalcification of the cornea with ethylene diamine tetra-acetic acid had been performed on the right eye, it was decided to proceed with pars-plana lensectomy and vitrectomy in the same (better preserved) eye. The surgery was performed as planned, with an uneventful postoperative course. Three years later, the eye operated upon had no signs of inflammation, and the visual acuity achieved with the aphakic correction was 0.8.

Sympathetic ophthalmia, a genuine autoimmune disease.

Intraocular inflammation of exogenous origin, which may lead to the loss of visual function in both eyes, i.e. SO confronts ophthalmologists much less rarely than might be expected. Epidemiological studies comprising ergophthalmological aspects underscore this. Questions with regard to therapy should consider the fact that the T cell-mediated cytotoxic disease which causes the transition from the initially unilateral subthreshold exogenous uveitis into the bilateral progressive phase is by no means a rare disorder, especially in secondary surgical operations on predamaged eyes with fresh intraocular hemorrhages, vascular neoplasia and secondary glaucoma. This should be recalled again by practicing ophthalmologists, thus enabling the prevention of SO. If SO is a "forme fruste" of retinitis pigmentosa, as is very likely to be the case, further clarification requires clinicopathologic studies in close collaboration with immunologists.

Twenty cases of sympathetic ophthalmia.

We reviewed the charts of 20 patients with sympathetic ophthalmia who were seen in the uveitis clinic at the Eye and Ear Infirmary within an 11-year period. Of these 20 patients 14 maintained 20/50 or better visual acuity in at least one eye. We found early enucleation to be associated with a better visual prognosis, possibly due to earlier diagnosis and faster, more aggressive therapy rather than a reduction in antigenic load. The clinical appearance of Dalen-Fuchs nodules appears to indicate a more severe stage of disease. Chlorambucil was useful in patients with severe disease. To be effective and to lessen its side effects chlorambucil was given in daily dosages that were increased weekly over a short period to achieve bone marrow suppression. After a course of chlorambucil therapy intraocular inflammation could be controlled with topical steroids alone.

[Sympathetic ophthalmia following interventions for hemorrhagic glaucoma]. / Sympathische Ophthalmie nach Eingriffen wegen eines hämorrhagischen Glaukoms.

A case of sympathetic uveitis which developed after several operations to reduce intraocular pressure is reported. Initially there was a thrombosis of the central vein; secondary glaucoma developed after laser coagulation and iridectomy; six operations followed. Some months later the diagnosis of sympathetic uveitis was established. The pathogenesis of sympathetic uveitis in this case is discussed.

Thirty-year history of sympathetic ophthalmia.

A spontaneous corneal perforation followed by granulomatous uveitis occurred in a 10-month-old female infant with bilateral anterior segment anomalies. The histopathologic findings in the enucleated right eye and the 30-year course of intraocular inflammation in her left eye are consistent with sympathetic ophthalmia. This case illustrates that sympathetic ophthalmia can be overlooked for years unless the diagnosis is considered and periodic anterior segment biomicroscopy and indirect ophthalmoscopy are performed in patients who have had perforating ocular injuries. A lensectomy-vitrectomy procedure was successful in restoring ambulatory vision in this patient.
