Insights into the diagnosis and management of sarcoid uveitis: A review. Clin Exp Ophthalmol 2024; 52:294-316. [PMID: 38385625 DOI: 10.1111/ceo.14366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 01/08/2024] [Accepted: 01/19/2024] [Indexed: 02/23/2024]
Abstract
Sarcoidosis is a leading cause of non-infectious uveitis that commonly affects middle-aged individuals and has a female preponderance. The disease demonstrates age, sex and ethnic differences in clinical manifestations. A diagnosis of sarcoidosis is made based on a compatible clinical presentation, supporting investigations and histologic evidence of non-caseating granulomas, although biopsy is not always possible. Multimodal imaging with widefield fundus photography, optical coherence tomography and angiography can help in the diagnosis of sarcoid uveitis and in the monitoring of treatment response. Corticosteroid remains the mainstay of treatment; chronic inflammation requires steroid-sparing immunosuppression. Features on multimodal imaging such as vascular leakage may provide prognostic indicators of outcome. Female gender, prolonged and severe uveitis, and posterior involving uveitis are associated with poorer visual outcomes.

Role of screening for uveitis in subjects with sarcoidosis. Respir Med 2024; 224:107562. [PMID: 38342356 DOI: 10.1016/j.rmed.2024.107562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 01/09/2024] [Accepted: 02/08/2024] [Indexed: 02/13/2024]
Abstract
BACKGROUND AND OBJECTIVES Ocular involvement is common in sarcoidosis. Our study aimed to evaluate the role of screening for uveitis in subjects with sarcoidosis. METHODS Retrospective case series of 88 subjects with a pre-existing diagnosis of sarcoidosis, with no previous diagnosis of uveitis, reviewed by Ophthalmology at Auckland District Health Board between January 2016 and May 2022. RESULTS Among those undergoing a screening examination, uveitis was observed in 27.8% (15 out of 54 subjects). In those presenting with acute eye symptoms, uveitis was observed in 94.1% (32 out of 34 subjects). Sarcoid uveitis was diagnosed in a total of 50 out of 88 subjects (56.8%). 45 subjects required ocular treatment. Sarcoid uveitis was observed in 6 out of 27 subjects (22.2%) who were entirely asymptomatic at screening. On multivariate analysis, blurring of vision (OR 26.2 p < 0.001), eye pain (OR 7.3 p = 0.014) and respiratory disease (OR 7.1 p = 0.044) were associated with increased risk of sarcoid uveitis. In the 41 subjects with no uveitis at initial examination, 3 subjects (7.3%) subsequently developed uveitis. CONCLUSION Our study highlights the importance of ophthalmic screening of all patients with systemic sarcoidosis, even in asymptomatic patients. With a high correlation of ocular symptoms in diagnosis of sarcoid uveitis, ophthalmologists should educate patients to look out for the development of symptoms of ocular inflammation, and clinicians who continue follow up for systemic sarcoidosis should remind patients to watch carefully for these symptoms to facilitate timely diagnosis and intervention.

Abstract
PURPOSE To provide an overview of pediatric pars planitis. METHODS Narrative literature review. RESULTS Pars planitis refers to the idiopathic subset of intermediate uveitis in which there is vitritis along with snowball or snowbank formation occurring in the absence of an associated infection or systemic disease. It is thought to be a T-cell mediated disease with a genetic predisposition. Pars planitis accounts for 5-26.7% of pediatric uveitis cases. Presentation is commonly bilateral but asymmetric, often with insidious onset of floaters and blurred vision. Although pars planitis is known to be a benign form of uveitis in most cases, severe complications secondary to chronic inflammation may arise, with cystoid macular edema being the most common cause of visual morbidity. Mild vitritis in the absence of symptoms, vision loss, or macular edema may be observed. Patients with severe vitritis and/or associated vision-threatening complications require prompt aggressive treatment. A stepladder approach including corticosteroids, immunosuppressive agents, anti‑tumor necrosis factor‑alpha and pars plana vitrectomy and/or laser photocoagulation is the most commonly used method for treatment of pars planitis. CONCLUSION Timely diagnosis and adequate treatment of pediatric pars planitis and associated complications are crucial in order to improve visual outcomes.

Abstract
BACKGROUND Sarcoidosis is a multisystemic granulomatous disease of unknown origin. It is characterized by abnormal activation of lymphocytes and macrophages with the formation of granulomas. Most cases have asymptomatic pulmonary involvement. In case of symptoms, they have an excellent response to glucocorticoid therapy. We present a case of sarcoidosis with multi-organ involvement, refractory to multiple treatments including biological. Partial remission was achieved in it. CASE PRESENTATION We report an interesting case of a 38-years-old Spanish woman treated by Heerfordt's syndrome (uveitis, parotiditis, fever and facial palsy) plus pulmonary hiliar adenopathy. A sarcoidosis diagnosis was confirmed by lung biopsy. She was initially treated with an 8 weeks course of medium dose oral glucocorticoids and tapered over 8 weeks with improvement. After the suspension of glucocorticoids a relapse occurs with severe ocular involvement and suspicion of neurological involvement. The patient received multiple lines of treatment with poor response. Finally, after the combination of cyclophosphamide with infliximab, the uveitis resolved, improving the neurological symptoms. CONCLUSIONS Sarcoidosis is a benign disease in most cases. In a small percentage of cases behaves aggressively, requiring early diagnosis and immunosuppressive treatment to avoid sequelae. An adequate immunosuppressive therapy based on Anti TNF drugs should be started to minimize damage and improve the quality of life.The choice of treatment depends on the type and severity of the disease.

Abstract
Purpose To present a case of extrapulmonary sarcoidosis presenting with ocular and cutaneous involvement. Observations We report a 54-year-male who presented with bilateral redness of eyes, photophobia, and diminished vision for a week. The best corrected visual acuity in the right eye was 6/60 and the left eye was counting fingers close to face (CFCF). He also had multiple brown plaques on the nape of the neck, chest, back, and arms. Furthermore, he was on multiple antipsychotic drugs for schizophrenia for 3 years. Uveitis investigation workup revealed raised serum angiotensin converting enzyme (ACE), negative Mantoux, and other serological tests. The patient was treated for acute anterior uveitis secondary to sarcoidosis. Clinical improvement was seen after a few days following treatment. The patient presented a year later with multiple yellowish conjunctival nodules in the superior bulbar conjunctiva associated with hyperemia. A biopsy of the plaque like skin lesions was done, which suggested cutaneous sarcoidosis. Involvement of the skin and the eyes raised suspicion that the persistent psychotic episodes despite multiple antipsychotic drugs could be attributed to neurosarcoidosis. However, magnetic Resonance Imaging (MRI) of the brain and orbit showed normal findings. After treatment with corticosteroids and immunosuppressives (methotrexate), the conjunctival nodules as well as skin lesions drastically improved, and the psychosis also responded well to clozapine. Conclusion A high index of suspicion is needed in cases presenting with granulomatous uveitis with multisystem involvement. Long-term follow-up is crucial to monitor the disease progression and adverse effects of medications.

Abstract
The purpose of our work is to describe the actual knowledge concerning etiopathogenesis, clinical manifestations, diagnostic procedures, complications and therapy of ocular sarcoidosis (OS). The study is based on a recent literature review and on the experience of our tertiary referral center. Data were retrospectively analyzed from the electronic medical records of 235 patients (461 eyes) suffering from a biopsy-proven ocular sarcoidosis. Middle-aged females presenting bilateral ocular involvement are mainly affected; eye involvement at onset is present in one-third of subjects. Uveitis subtype presentation ranges widely among different studies: panuveitis and multiple chorioretinal granulomas, retinal segmental vasculitis, intermediate uveitis and vitreitis, anterior uveitis with granulomatous mutton-fat keratic precipitates, iris nodules, and synechiae are the main ocular features. The most important complications are cataract, glaucoma, cystoid macular edema (CME), and epiretinal membrane. Therapy is based on the disease localization and the severity of systemic or ocular involvement. Local, intravitreal, or systemic steroids are the mainstay of treatment; refractory or partially responsive disease has to be treated with conventional and biologic immunosuppressants. In conclusion, we summarize the current knowledge and assessment of ophthalmological inflammatory manifestations (mainly uveitis) of OS, which permit an early diagnostic assay and a prompt treatment.

Abstract
Purpose To report a case of multiple pre-retinal and intra-retinal lesions in the context of probable sarcoidosis. Observations A 31-year-old black woman presented with a bilateral panuveitis and multiple pre-retinal and retinal nodules. The workup showed enlarged mediastinal lymph nodes as well as meningitis with an increased cerebrospinal fluid angiotensin-converting enzyme (ACE) [0.36 UI/L (1.44 × normal)] leading to the diagnosis of probable sarcoidosis. The nodules were hyper-reflective, with posterior shadowing on OCT imaging, and appeared as multiple hypoautofluorescent spots: their characteristics were suggestive of intra and preretinal granulomas. The intraretinal nodules were located in the ganglion cell layer. The posterior segment manifestations were limited to the retina while the choroid appeared uninvolved including on indocyanine green angiograms. The lesions disappeared after corticosteroid treatment. Conclusions and importance Retinal and pre-retinal nodules have rarely been reported as the sole posterior manifestations of ocular sarcoidosis without choroidal involvement.

Abstract
AIM To document atypical presenting forms of ocular sarcoidosis at the corneal level. METHODS Case report. RESULTS A 63-year-old woman presented multiple uncommon unilateral primary corneal conditions as manifestation of ocular sarcoidosis, including peripheral ulcerative keratitis, sterile corneal infiltrate (corneal granuloma), and sterile infiltrates related to a corneal foreign body, requiring medical and surgical management to control the inflammatory symptoms and to preserve the integrity of the eyeball. An excisional biopsy of a nodule in the temporal conjunctiva was performed under topical anesthesia. Histological analysis revealed a non-caseating granuloma, confirming the diagnosis of ocular sarcoidosis. CONCLUSION When thinking of ocular involvement in patients with ocular sarcoidosis, it is essential to remember that manifestations such as peripheral ulcerative keratitis, sterile corneal infiltrate, and sterile foreign body-related infiltrates may be presentations of this disease.

Abstract
The challenges of childhood uveitis lie in the varied spectrum of its clinical presentation, the often asymptomatic nature of disease, and the evolving nature of the phenotype alongside normal physiological development. These issues can lead to delayed diagnosis which can cause significant morbidity and severe visual impairment. The most common ocular complications include cataracts, band keratopathy, glaucoma, and macular oedema, and the various associated systemic disorders can also result in extra-ophthalmic morbidity. Pediatricians have an important role to play. Their awareness of the various presentations and etiologies of uveitis in children afford the opportunity of prompt diagnosis before complications arise. Juvenile Idiopathic Arthritis (JIA) is one of the most common associated disorders seen in childhood uveitis, but there is a need to recognize other causes. In this review, different causes of uveitis are explored, including infections, autoimmune and autoinflammatory disease. As treatment is often informed by etiology, pediatricians can ensure early ophthalmological referral for children with inflammatory disease at risk of uveitis and can support management decisions for children with uveitis and possible underling multi-system inflammatory disease, thus reducing the risk of the development of irreversible sequelae.

Abstract
Sarcoidosis and sarcoid-like reactions (SLR) have been repeatedly reported in patients with melanoma treated with BRAF and MEK inhibitors. In the current study we present three patients that developed SLR under treatment with BRAF and mitogen-activated protein kinase (MEK) inhibitors for melanoma. Two patients developed mediastinal lymphadenitis with histological features of an SLR while on targeted therapy in the adjuvant setting, whereas one patient with metastatic melanoma developed granulomatous nephritis while receiving combination treatment with BRAF/MEK inhibitors and atezolizumab. In addition, we review the published literature on the pathogenesis, clinical characteristics, histologic features, imaging findings, and other potential useful diagnostic tools. We also address the need for a common terminology for these cases and propose an algorithm for the accurate diagnosis of BRAF/MEK inhibitor-induced SLR. We also review the currently available data on the treatment of these patients and suggest a treatment approach for SLR in patients with melanoma, as well as for the management of melanoma when SLR emerges.

Abstract
PURPOSE To compare the differences among clinical, demographic, and multimodal imaging features of choroidal granulomas associated with tuberculosis and sarcoidosis. DESIGN Retrospective comparative case series. METHODS Clinical features and fundus imaging, including fluorescein and indocyanine green angiography and optical coherence tomography of patients with tuberculomas and sarcoid choroidal granulomas seen at 3 tertiary care centers, were reviewed. The differences among clinical appearances, including morphology of the lesions (size, shape, extent), vascularity, and multimodal imaging features, were compared. Repeated logistic regression measurements with a multilevel random effects model was used to assess characteristics of individual granulomas that could predict the underlying cause. RESULTS The study included 47 eyes of 38 patients (22 with tuberculomas and 16 with sarcoid granulomas; total of 138 granulomas). Patients with tuberculomas were significantly younger (33.8 ± 10.1 vs. 48.6 ± 14.3 years, respectively; P = .002), but no sex differences were observed. In comparison with sarcoid granulomas, tuberculomas were solitary (P <.001), intense yellow, lobulated, full thickness, and located in the perivascular region (all P <.001); they were also larger (16.01 ± 9.7 mm2 vs. 2.7 ± 4.5 mm2, respectively; P <.001) and were vascularized (P <.001). Sarcoid granulomas were associated with retinal vasculitis (P = .003) and disc hyperfluorescence (P <.001). Logistic regression showed that multiple granulomas were associated with sarcoidosis (odds ratio [OR]: 3.5; 95% confidence interval: 1.8-6.9; P <.001). Granulomas larger than 6.45 mm2 had the highest area under the receiver operating curves (0.94) for differentiating tuberculomas from sarcoid granulomas. CONCLUSIONS Tuberculomas and sarcoid choroidal granulomas have various clinical and imaging features that help differentiate between the 2 entities with high predictability and can supplement immunological and radiological tests in a diagnosis.

Abstract
An intraocular biopsy is performed for diagnostic, prognostic and investigational purposes. Biopsies help to confirm or exclude malignancies and differentiate inflammatory from infectious processes. Histopathological analysis is the final verdict in unresponsive uveitis, atypical inflammation, metastases and masquerade syndromes. Advances and refinement of techniques in cytopathology, immunohistochemistry, microbiological and molecular biologic study offer much more than just diagnosis. They provide prognosis based on cell characteristics and are helpful in planning treatment and intervention. Many biopsy procedures have evolved to provide more safety and minimise complications thus improving the quality of specimens or samples available for analysis. The type of biopsy and technique adopted varies based on the clinical suspicion, size and location of lesions. In uveitis, a working diagnosis of intraocular inflammation is made on clinical examination and laboratory investigations and ancillary tests. Malignancy and uveitis is interlinked and masquerade syndromes are among the commonest indications for biopsy and analysis of specimen. The various types of intraocular biopsies include aqueous tap, fine needle aspiration biopsy, vitreous biopsy, iris and ciliary body, and retinochoroidal biopsy. They will be reviewed in this article with respect to current perspective

Abstract
PURPOSE Ocular sarcoidosis is diagnosed based on suggestive intraocular findings and systemic investigations. In this study, we assessed the clinical usefulness of systemic parameters in the diagnosis of ocular sarcoidosis. STUDY DESIGN A retrospective study. METHODS This study included 79 cases (19 men, 60 women) with ocular sarcoidosis who visited Hokkaido University Hospital from 2011 to 2015 and were followed up for more than one year. The control group was 91 cases of other uveitis (38 men, 53 women). All cases underwent blood examination for the measurement of angiotensin-converting enzyme (ACE), Krebs von den Lungen-6 (KL-6), soluble interleukin-2 receptor (sIL-2R), and calcium (Ca) levels. Bilateral hilar lymphadenopathy (BHL) was also examined by plain chest X-ray and contrasting chest computed tomography (CT). RESULTS The sensitivity for sIL-2R (76.4%) was higher than for ACE (37.7%), KL-6 (26.3%), and Ca (11.8%), although all showed high specificity: ACE (97.5%), KL-6 (96.2%), sIL-2R (93.8%), and Ca (95.1%). From these results, the Youden index of sIL-2R (0.70) was higher than that of ACE (0.35), KL-6 (0.26), and Ca (0.07). Imaging tests revealed better detection of BHL by contrasting chest CT (82.7%) than by plain chest X-ray (29.5%). CONCLUSION The present findings indicate that the systemic parameters, particularly serum sIL-2R levels and BHL on contrasting chest CT, are useful biomarkers for the diagnosis of ocular sarcoidosis.

Abstract
Purpose To describe the ocular manifestations in a cohort of patients with systemic sarcoidosis (SS). Recent advances in the pathophysiology, diagnosis, and therapy of SS are also discussed. Methods Data from 115 Italian patients diagnosed between 2005 and 2016 were retrospectively reviewed. All but the first 17 patients underwent a comprehensive ophthalmologic examination. The diagnosis was based on clinical features, the demonstration of non-caseating granulomas in biopsies from involved organs, and multiple imaging techniques. Data on broncho-alveolar lavage fluid analysis, calcemia, calciuria, serum angiotensin-converting enzyme levels and soluble interleukin-2 receptor levels were retrieved when available. Results Ocular involvement, detected in 33 patients (28.7%), was bilateral in 29 (87.9%) and the presenting feature in 13 (39.4%). Anterior uveitis was diagnosed in 12 patients (36.4%), Löfgren syndrome and uveoparotid fever in one patient each (3%), intermediate uveitis in 3 patients (9.1%), posterior uveitis in 7 (21.2%), and panuveitis in 9 (27.3%). First-line therapy consisted of corticosteroids, administered as eyedrops (10 patients), sub-Tenon’s injections (1 patient), intravitreal implants (9 patients), or systemically (23 patients). Second-line therapy consisted of steroid-sparing immunosuppressants, including methotrexate (10 patients) and azathioprine (10 patients). Based on pathogenetic indications that tumor necrosis factor (TNF)-α is a central mediator of granuloma formation, adalimumab, targeting TNF-α, was employed in 6 patients as a third-line agent for severe/refractory chronic sarcoidosis. Conclusion Uveitis of protean type, onset, duration, and course remains the most frequent ocular manifestation of SS. Diagnostic and therapeutic advancements have remarkably improved the overall visual prognosis. An ophthalmologist should be a constant component in the multidisciplinary approach to the treatment of this often challenging but intriguing disease.

Abstract
Non-specific orbital inflammation (NSOI) is a noninfectious inflammatory condition of the orbit. Although it is generally considered the most common diagnosis derived from an orbital biopsy, it is a diagnosis of exclusion, meaning that the diagnosis requires exclusion of a systemic process or another identifiable etiology of orbital inflammation. The clinical diagnosis of NSOI is ill-defined, but it is typically characterized by acute orbital signs and symptoms, including pain, proptosis, periorbital edema, chemosis, diplopia, and less commonly visual disturbance. NSOI poses a diagnostic and therapeutic challenge: The clinical presentations and histological findings are heterogeneous, and there are no specific diagnostic criteria or treatment guidelines. The etiology and pathogenesis of NSOI are poorly understood. Here we recapitulate our current clinical understanding of NSOI, with an emphasis on the most recent findings on clinical characteristics, imaging findings, and treatment outcomes. Furthermore, gene expression profiling of NSOI and its implications are presented and discussed.

Abstract
Background: The diagnosis of sarcoidosis is not standardized but is based on three major criteria: a compatible clinical presentation, finding nonnecrotizing granulomatous inflammation in one or more tissue samples, and the exclusion of alternative causes of granulomatous disease. There are no universally accepted measures to determine if each diagnostic criterion has been satisfied; therefore, the diagnosis of sarcoidosis is never fully secure. Methods: Systematic reviews and, when appropriate, meta-analyses were performed to summarize the best available evidence. The evidence was appraised using the Grading of Recommendations, Assessment, Development, and Evaluation approach and then discussed by a multidisciplinary panel. Recommendations for or against various diagnostic tests were formulated and graded after the expert panel weighed desirable and undesirable consequences, certainty of estimates, feasibility, and acceptability. Results: The clinical presentation, histopathology, and exclusion of alternative diagnoses were summarized. On the basis of the available evidence, the expert committee made 1 strong recommendation for baseline serum calcium testing, 13 conditional recommendations, and 1 best practice statement. All evidence was very low quality. Conclusions: The panel used systematic reviews of the evidence to inform clinical recommendations in favor of or against various diagnostic tests in patients with suspected or known sarcoidosis. The evidence and recommendations should be revisited as new evidence becomes available.

Abstract
Sarcoidosis is a multi-system disease of unknown etiology characterized by granuloma formation in various organs (especially lung and mediastinohilar lymph nodes). In more than half of patients, the disease resolves spontaneously. When indicated, it usually responds to corticosteroids, the first-line treatment, but some patients may not respond or tolerate them. An absence of treatment response is rare and urges for verifying the absence of a diagnosis error, the good adherence of the treatment, the presence of active lesions susceptible to respond since fibrotic lesions are irreversible. That is when second-line treatments, immunosuppressants (methotrexate, leflunomide, azathioprine, mycophenolate mofetil, hydroxychloroquine), should be considered. Methotrexate is the only first-line immunosuppressant validated by a randomized controlled trial. Refractory sarcoidosis is not yet a well-defined condition, but it remains a real challenge for the physicians. Herein, we considered refractory sarcoidosis as a disease in which second-line treatments are not sufficient to achieve satisfying disease control or satisfying corticosteroids tapering. Tumor necrosis alpha inhibitors, third-line treatments, have been validated through randomized controlled trials. There are currently no guidelines or recommendations regarding refractory sarcoidosis. Moreover, criteria defining non-response to treatment need to be clearly specified. The delay to achieve response to organ involvement and drugs also should be defined. In the past ten years, the efficacy of several immunosuppressants beforehand used in other autoimmune or inflammatory diseases was reported in refractory cases series. Among them, anti-CD20 antibodies (rituximab), repository corticotrophin injection, and anti-JAK therapy anti-interleukin-6 receptor monoclonal antibody (tocilizumab) were the main reported. Unfortunately, no clinical trial is available to validate their use in the case of sarcoidosis. Currently, other immunosuppressants such as JAK inhibitors are on trial to assess their efficacy in sarcoidosis. In this review, we propose to summarize the state of the art regarding the use of immunosuppressants and their management in the case of refractory or multidrug-resistant sarcoidosis.

Abstract
Introduction: Care of patients with sarcoidosis requires familiarity with its natural history as well as of various immunosuppressants employed in its treatment. We would like to share our approach to management based on our experience and understanding of the relevant literature.Areas covered: Asymptomatic patients with pulmonary sarcoidosis ought to be managed conservatively. Systemic sarcoidosis with burdensome symptoms usually responds to corticosteroids, but one needs to consider the risk of long-term steroid toxicity as well as relapse. Rapidly tapering steroids can decrease cumulative exposure without compromising efficacy. Steroid-sparing anti-sarcoidosis (SSAS) agents take longer to act and are associated with unique but mostly reversible toxicities. Used judiciously and with careful monitoring, they effectively suppress granulomatous inflammation. Patients intolerant of or failing to improve with a particular drug can be switched to another, and occasionally combination therapy with two SSAS agents might prove effective. A small proportion of patients are refractory, but often achieve control and sometimes remission with stepping up to biologic therapy.Expert opinion: Adopting a strategy of early SSAS therapy ought to effectively control sarcoidosis and avoid harm from prolonged corticosteroid dosing.

The Role of Steroids and NSAIDs in Prevention and Treatment of Postsurgical Cystoid Macular Edema. Curr Pharm Des 2019; 24:4896-4902. [PMID: 30727876 DOI: 10.2174/1381612825666190206104524] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Accepted: 01/24/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Pseudophakic cystoid macular edema (PCME) remains one of the most common visionthreatening complication of phacoemulsification cataract surgery (PCS). Pharmacological therapy is the current mainstay of both prophylaxis, and treatment of PCME in patients undergoing PCS. We aimed to review pharmacological treatment options for PCME, which primarily include topical steroids, topical nonsteroidal antiinflammatory drugs (NSAIDS), periocular and intravitreal steroids, as well as anti-vascular endothelial growth factor therapy. METHODS The PubMed and Web Of Science web platforms were used to find relevant studies using the following keywords: cataract surgery, phacoemulsification, cystoid macular edema, and pseudophakic cystoid macular edema. Of articles retrieved by this method, all publications in English and abstracts of non-English publications were reviewed. Other studies were also considered as a potential source of information when referenced in relevant articles. The search revealed 193 publications. Finally 82 articles dated from 1974 to 2018 were assessed as significant and analyzed. RESULTS Based on the current literature, we found that corticosteroids remain the mainstay of PCME prophylaxis in uncomplicated cataract surgery, while it is still unclear if NSAID can offer additional benefits. In patients at risk for PCME development, periocular subconjunctival injection of triamcinolone acetonide may prevent PCME development. For PCME treatment the authors recommend a stepwise therapy: initial topical steroids and adjuvant NSAIDs, followed by additional posterior sub-Tenon or retrobulbar corticosteroids in moderate PCME, and intravitreal corticosteroids in recalcitrant PCME. Intravitreal anti-vascular endothelial growth factor agents may be considered in patients unresponsive to steroid therapy at risk of elevated intraocular pressure, and with comorbid macular disease. CONCLUSION Therapy with topical corticosteroids and NSAIDs is the mainstay of PCME prophylaxis and treatment, however, periocular and intravitreal steroids should be considered in refractory cases.

Repeatability of Optical Coherence Tomography Angiography in Uveitic Eyes. Transl Vis Sci Technol 2019; 8:17. [PMID: 31772828 PMCID: PMC6859831 DOI: 10.1167/tvst.8.6.17] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2019] [Accepted: 09/23/2019] [Indexed: 12/30/2022] Open
Abstract
Purpose To investigate the intravisit repeatability of optical coherence tomography angiography (OCTA) in a cohort of uveitis patients. Methods One hundred ten patients were imaged twice per eye, per visit, using the Zeiss Cirrus HD-OCT Model 5000 device. To calculate choriocapillaris flow void area (CC FV) 6 × 6-mm images were used, and 3 × 3-mm images were used to calculate vessel density (VD) and the foveal avascular zone area (FAZ) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP). Repeatability was measured using Bland-Altman analyses and intraclass correlation coefficients (ICC) with associated coefficient of variation (CV). Results The level of intravisit repeatability differed across indices ranging from moderate to excellent. CC FV had the highest intravisit repeatability with an ICC of 0.980 (95%CI, 0.966–0.989), a CV of 15.9% and Bland-Altman limits of agreement from −0.398 to 0.411 mm2. DCP FAZ had the lowest intravisit repeatability with an ICC of 0.677 (95%CI, 0.510–0.796), a CV of 17.4% and Bland-Altman limits of agreement from −0.395 to −0.355 mm2. Intraoperator repeatability was excellent across all indices. Conclusions This study demonstrates that OCTA is a reliable tool to quantitatively assess specific indices of vascular structure in uveitis patients with good intravisit repeatability. However, the range of variability for each index should be taken into account when evaluating clinically meaningful changes. Translational Relevance The repeatability of the metrics we have described has implications in supporting the development of OCTA-derived quantitative assessments of the retinal and choroidal vasculature in uveitis patients as potential imaging biomarkers.

Abstract
BACKGROUND Syphilis, tuberculosis and toxoplasmosis are major infectious diseases worldwide; all of them are multisystem pathologies and share a possible ocular involvement. In this context, a fundamental help for the definitive diagnosis is provided by the ophthalmologist, through clinical evaluation and with the aid of a multimodal imaging examination. METHODS We hereby describe selected cases who came to our attention and were visited in our eye clinic. In all clinics, the use of retinal and optic disc multimodal imaging during ophthalmological evaluation allowed to make a diagnosis of an infectious disease. RESULTS In our tertiary referral center more than 60 patients with syphilis, tuberculosis and toxoplasmosis have been evaluated in the last two years: In 60% of cases the ophthalmological evaluation was secondary to a previous diagnosis of an infectious disease, while in the remaining cases the ophthalmologist, with the help of a multimodal imaging examination and clinical evaluation, represented the physician who leads to the diagnosis. CONCLUSION Our results confirm how in these life-threatening pathologies a prompt diagnosis is mandatory and may benefit from a multidisciplinary and multimodal imaging approach, especially during ophthalmological evaluation.

Abstract
Sarcoidosis is a systemic granulomatous lung disease of unknown origin affecting people of any age, mainly young adults. The disease is extremely heterogeneous with an unpredictable clinical course. Different phenotypes have been identified: an acute syndrome can be distinguished from subacute and chronic variants. About 20% of patients are chronically progressive and may develop lung fibrosis. Sarcoidosis usually involves the lungs and thoracic lymph nodes, although the skin, eyes, bones, liver, spleen, heart, upper respiratory tract and nervous system can also be affected. No reliable indicators of clinical outcome are available, and there is no single serological biomarker with demonstrated unequivocal diagnostic and prognostic value. Diagnosis requires histological confirmation although a presumptive diagnosis may be acceptable in special conditions. This review examines the diagnostic approach to sarcoidosis involving a multidisciplinary team of specialists in which the internist has the task of identifying all pulmonary and extrapulmonary localizations of the disease and of managing complications and comorbidities.

Abstract
Background Sarcoidosis constitutes one of the leading causes of ocular inflammation. Chronic ocular sarcoidosis can affect any segment of the eye and its adnexa, producing a wide range of clinical manifestations and severity. If left untreated, permanent visual impairment or even blindness may ensue. Treatment approaches vary from topical therapy to systemic agents that induce immunosuppression to different levels according to disease severity. Objective To review the published literature on the management options for chronic ocular sarcoidosis and provide a comprehensive list of available treatment strategies, including the newer biologics. Summary Ocular disease remains a challenging aspect of sarcoidosis and may even be the presenting sign of the disease. Prompt and effective therapy may reverse visual damage and prevent permanent loss of vision. Because of the complexity of the disease, a multidisciplinary approach is often required, with a view to addressing both the ocular and other systemic manifestations of sarcoidosis. Recent data suggest that achieving overall optimal systemic control is of paramount importance in controlling eye inflammation as well. Cytotoxic immunosuppressive agents for refractory chronic ocular disease, as well as biologic anti-TNFα therapies, have advanced the management of chronic disease and should be considered corticosteroid-sparing strategies before the onset of significant steroid-induced morbidity.
