Use of Immunosuppression and the Risk of Subsequent Overall or Cancer Mortality.

PURPOSE: To determine the incidence of all-cause and cancer mortality (CM) in association with immunosuppression. DESIGN: Retrospective cohort study at ocular inflammatory disease (OID) subspecialty centers. We harvested exposure and covariate data retrospectively from clinic inception (earliest in 1979) through 2010 inclusive. Then we ascertained overall and cancer-specific mortalities by National Death Index linkage. We constructed separate Cox models to evaluate overall and CM for each class of immunosuppressant and for each individual immunosuppressant compared with person-time unexposed to any immunosuppression. PARTICIPANTS: Patients with noninfectious OID, excluding those with human immunodeficiency infection or preexisting cancer. METHODS: Tumor necrosis factor (TNF) inhibitors (mostly infliximab, adalimumab, and etanercept); antimetabolites (methotrexate, mycophenolate mofetil, azathioprine); calcineurin inhibitors (cyclosporine); and alkylating agents (cyclophosphamide) were given when clinically indicated in this noninterventional cohort study. MAIN OUTCOME MEASURES: Overall mortality and CM. RESULTS: Over 187 151 person-years (median follow-up 10.0 years), during which 15 938 patients were at risk for mortality, we observed 1970 deaths, 435 due to cancer. Both patients unexposed to immunosuppressants (standardized mortality ratio [SMR] = 0.95, 95% confidence interval [CI], 0.90-1.01) and those exposed to immunosuppressants but free of systemic inflammatory diseases (SIDs) (SMR = 1.04, 95% CI, 0.95-1.14) had similar mortality risk to the US population. Comparing patients exposed to TNF inhibitors, antimetabolites, calcineurin inhibitors, and alkylating agents with patients not exposed to any of these, we found that overall mortality (adjusted hazard ratio [aHR] = 0.88, 0.89, 0.90, 1.11) and CM (aHR = 1.25, 0.89, 0.86, 1.23) were not significantly increased. These results were stable in sensitivity analyses whether excluding or including patients with SID, across 0-, 3-, or 5-year lags and across quartiles of immunosuppressant dose and duration. CONCLUSIONS: Our results, in a cohort where the indication for treatment was proven unassociated with mortality risk, found that commonly used immunosuppressants-especially the antimetabolites methotrexate, mycophenolate mofetil, and azathioprine; the TNF inhibitors adalimumab and infliximab, and cyclosporine-were not associated with increased overall and CM over a median cohort follow-up of 10.0 years. These results suggest the safety of these agents with respect to overall and CM for patients treated with immunosuppression for a wide range of inflammatory diseases.

ULTRA-WIDEFIELD MULTIMODAL IMAGING OF PRIMARY VITREORETINAL LYMPHOMA.

PURPOSE: To determine the features of primary vitreoretinal lymphoma on multimodal ultra-widefield imaging and correlate these findings to clinical outcomes. METHODS: We report a retrospective, observational case series of 43 eyes of 23 patients with biopsy-proven B-cell primary vitreoretinal lymphoma. Fundus photography, fluorescein angiography (FA), optical coherence tomography, fundus autofluorescence, and indocyanine green angiography images were reviewed. Medical records were assessed for the central nervous system involvement and visual acuity outcomes at 6 and 12 months after presentation. RESULTS: Common fundus photography findings were sub-retinal pigment epithelium lesions and vitritis alone. Common ultra-widefield FA findings were vascular leakage and scleral staining. Retinal optical coherence tomography features overlying sub-retinal pigment epithelium lesions or within the macula predicted fluorescence patterns. The presence of retinal fluid or disorganization associated with hyperfluorescence and late leakage. Normal retinal structures associated with hypofluorescence of sub-retinal pigment epithelium lesions or macular leopard spotting on FA and fundus autofluorescence. Peripheral abnormalities noted on ultra-widefield fundus photography, FA, and indocyanine green angiography were more frequent than posterior pole abnormalities. No imaging characteristics predicted time to the central nervous system progression. CONCLUSION: Ultra-widefield imaging was more informative than posterior pole imaging in fundus photography, FA, and indocyanine green angiography. Common findings on multimodal ultra-widefield imaging may lead to early diagnostic vitrectomy and may reduce the delay in primary vitreoretinal lymphoma diagnosis.

Herpes zoster keratitis development after acute retinal necrosis.

PURPOSE: To report a case of herpes zoster keratitis in a patient undergoing treatment for herpetic acute retinal necrosis. METHODS: Case report. RESULTS: A 71 year old male presented with acute retinal necrosis of the left eye due to herpes zoster and was treated with intravitreal foscarnet and oral valcyclovir. He developed a retinal detachment and underwent surgical repair. After four weeks, he developed an ipsilateral herpetic zoster keratitis demonstrated by Rose-Bengal staining that was responsive to topical ganciclovir gel. CONCLUSIONS: This case report describes the unusual development of herpes zoster keratitis after the development of unilateral acute retinal necrosis (ARN) in a patient on antiviral treatment.

PERIPHERAL RETINOSCHISIS IN INTERMEDIATE UVEITIS.

PURPOSE: To examine cases of intermediate uveitis complicated by retinoschisis and review the pathogenetic hypothesis. METHODS: A retrospective chart review of patients with intermediate uveitis. Data were collected at three uveitis referral centers on sex, age, best-corrected visual acuity, degree of vitritis, extent and location of snowbanking, presence of hard exudates, neovascularization, vitreous hemorrhage, and extent and nature of retinal elevations. RESULTS: A series of 23 eyes of 20 patients were examined; patient's age ranged from 10 years to 70 years and follow-up period from 8 months to 6 years. Twenty-two eyes had retinoschisis (95.6%), and 1 had retinoschisis associated with serous retinal detachment (4.3%). Extensive inferior pars plana exudates with snowbanking were present in 12 eyes (52.2%), whereas 3 eyes had inferior snowballs over the elevated retina. Neovascularization of the vitreous base accompanied by vitreous hemorrhage occurred in one eye. There was no coexisting macular pathology in 16 eyes, whereas 4 eyes had cystoid macular edema. CONCLUSION: The appearance of peripheral retinoschisis in this series of uncontrolled intermediate uveitis patients seems to be secondary to a complex balance between the persistent fluorescein leakage, a subclinical peripheral ischemia, and the constant low-grade vitreous inflammation that causes vitreous shrinkage and traction. The results of this study suggest that the absence of macroscopic changes in the retina does not preclude ischemic peripheral abnormalities, and the detection of a peripheral retinoschisis in an intermediate uveitis patient with active fluorescein leakage must suggest the need for a more aggressive form of treatment despite the good visual acuity.

RESOLUTION OF NONINFECTIOUS UVEITIC CYSTOID MACULAR EDEMA WITH TOPICAL DIFLUPREDNATE.

PURPOSE: To evaluate the short-term safety and efficacy of topical difluprednate (0.05%) for the treatment of noninfectious uveitic cystoid macular edema. METHODS: Twenty-seven patients (35 eyes) undergoing treatment with difluprednate 4 times daily for 3 weeks for noninfectious uveitic cystoid macular edema were reviewed for visual acuity, intraocular pressure, optical coherence tomography, and fluorescein angiography results. A mixed model analysis was fit with each measure as the outcome, visit as the primary predictor, and patient and eye as random effects. RESULTS: Mean central foveal thickness decreased by 117 µm (P < 0.001) at 30 ± 15 days, 124 µm (P < 0.001) at 60 ± 15 days, and 152 µm (P < 0.001) at 180 ± 30 days. Complete resolution of intraretinal fluid was observed in 15 of 34 (44%) eyes at 30 ± 15 days, 11 of 21 (52%) eyes at 60 ± 15 days, and 9 of 12 (75%) eyes at 180 ± 30 days. Improvement in fluorescein leakage was noted in 7 of 8 eyes (88%). Visual acuity improved by a mean of 5 letters (P = 0.001) at 30 ± 15 days, 5.5 letters (P = 0.007) at 60 ± 15 days, and 7 letters (P = 0.032) at 180 ± 30 days. Mean increase in intraocular pressure was 1.48 mmHg at 30 ± 15 days (P = 0.080), 1.92 mmHg at 60 ± 15 days (P = 0.110), and 6.18 mmHg (P = 0.001) at 180 ± 30 days. CONCLUSION: Topical difluprednate is a well-tolerated and effective treatment for noninfectious uveitic cystoid macular edema with decreased central foveal thickness, mild improvement in visual acuity, and elevation of intraocular pressure observed in a few patients.

Sustained-release dexamethasone intravitreal implant in juvenile idiopathic arthritis-related uveitis.

The purpose of this study is to review the results of treatment of juvenile idiopathic arthritis-related uveitis with the use of intravitreal dexamethasone implant. Sixteen eyes with Juvenile idiopathic arthritis (JIA)-associated uveitis received intravitreal dexamethasone implant to treat recalcitrant anterior segment inflammation (43.7 %), chronic macular edema (6.2 %), or a combination of both (50 %). One month after injection, mean visual acuity had improvement to 39.6 ± 11 ETDRS letters (p < 0.001). Mean AC cells measure at 1 month was 0.79 and 0.75 at 3 months. One month after injection, there was a significant reduction of central retinal thickness (CRT) to 342.4 ± 79.3 µm (p < 0.01). One month after the second implant, 11 eyes (91.6 %) achieved improved activity of the anterior uveitis, and mean best-corrected visual acuity improved to 44.6 ± 8.1 ETDRS letters (p < 0.01). At 1 month after the second injection, 4/5 eyes had resolution of macular edema with CRT of 250.4 ± 13.7 µm (p < 0.01). Of the 16 eyes, 12 eyes received a second injection at mean of 7.5 ± 3.1 months after the first treatment, and 5 eyes received a third Ozurdex injection on average 7 ± 4.6 months after the second injection. Of the 16 eyes, five eyes were pseudophakic prior to injection. Of the remaining 11 eyes, 8 (73 %) developed worsening posterior subcapsular cataract at a mean of 7.3 ± 1.2 months after the first injection. After the first injection, only one eye required topical antiglaucoma therapy with maximum pressure of 25 mmHg. In patients with recalcitrant JIA-associated active uveitis, injection of sustained-release dexamethasone can achieve control of anterior inflammation and resolution of macular edema.

EN FACE OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY OF MULTIPLE EVANESCENT WHITE DOT SYNDROME: New Insights Into Pathogenesis.

PURPOSE: To localize the various levels of abnormalities in multiple evanescent white dot syndrome by comparing "en face" optical coherence tomography (OCT) and OCT angiography with various conventional imaging modalities. METHODS: In this retrospective case series, multimodal imaging was performed in 9 retinal centers on 36 patients with multiple evanescent white dot syndrome and included widefield fundus autofluorescence (FAF), fluorescein angiography (FA), and indocyanine green angiography, and B-scan and "en face" C-scan enhanced depth imaging and spectral domain OCT. Optical coherence tomography angiography was also performed at the level of the superficial and deep retinal capillary plexus and choroid. RESULTS: Multiple evanescent white dot syndrome lesions were more numerous and more easily detectable with FA and FAF. Two types of lesions were identified with FAF, FA, and indocyanine green angiography: larger widely scattered "spots" (approximately 200 µ in diameter) that were hyperfluorescent with FA, hyperautofluorescent with FAF, and hyporeflective in indocyanine green angiography, representing abnormalities primarily at the retinal pigment epithelium/photoreceptor junction; and punctate "dots" (less than 100 µ in diameter) that were hyperfluorescent with FA, hyperautofluorescent, or isoautofluorescent with FAF, and hypofluorescent with indocyanine green angiography and that localized to the outer nuclear layer. These lesions colocalized with "en face" OCT. The larger confluent "spots" were hyporeflective and colocalized to the level of the ellipsoid zone, whereas smaller hyperreflective "dots" colocalized to the outer nuclear layer. The location of the "dots" in the outer nuclear layer was further confirmed by structural spectral domain optical coherence tomography which showed coalescence of the dots into hyperreflective lines extending from the external limiting membrane to the outer plexiform layer in certain cases. Optical coherence tomography angiography analysis of the retinal microvasculature and choriocapillaris and choroid were entirely unremarkable in 100% of our patients. CONCLUSION: By combining multimodal imaging, the authors propose that multiple evanescent white dot syndrome is primarily the result of inflammation at the outer photoreceptor level leading to a "photoreceptoritis" and causing loss of the inner and outer segments. Its evanescent nature suggests that the photoreceptor cell bodies remain intact ensuring complete recovery of the photoreceptor inner and outer segments in most cases, compatible with the clinical course of spontaneous resolution of white spots and dots.

Anterior segment spectral domain optical coherence tomography imaging of patients with anterior scleritis.

The purpose of the study was to describe the findings seen on anterior segment spectral domain optical coherence tomography (SD-OCT) in patients with anterior scleritis and determine the feasibility of using SD-OCT to image and grade the degree of scleral inflammation and monitor response to treatment. All patients underwent slit lamp examination by a uveitis specialist, and the degree of scleral inflammation was recorded. Spectral domain OCT imaging was then performed of the conjunctiva and scleral tissue using a standardized acquisition protocol. The scans were graded and compared to clinical findings. Twenty-eight patients with anterior scleritis and ten patients without ocular disease were included in the study. Seventeen of the scleritis patients were followed longitudinally. Common findings on SD-OCT in patients with active scleritis included changes in hyporeflectivity within the sclera, nodules, and visible vessels within the sclera. There was significant variation in findings on SD-OCT within each clinical grade of active scleritis. These changes on SD-OCT improved with treatment and clinical improvement. SD-OCT imaging provided various objective measures that could be used in the future to grade inflammatory activity in patients with anterior scleritis. Longitudinal imaging of patients with active scleritis demonstrated that SD-OCT may have great utility in monitoring response to treatment.

Genetic of uveitis.

Immune-mediated uveitis may be associated with a systemic disease or may be localized to the eye. T-cell-dependent immunological events are increasingly being regarded as extremely important in the pathogenesis of uveitis. Several studies have also shown that macrophages are major effectors of tissue damage in uveitis. Uveitis phenotypes can differ substantially, and most uveitis diseases are considered polygenic with complex inheritance patterns. This review attempts to present the current state of knowledge from in vitro and in vivo research on the role of genetics in the development and clinical course of uveitis. A review of the literature in the PubMed, MEDLINE, and Cochrane databases was conducted to identify clinical trials, comparative studies, case series, and case reports describing host genetic factors as well as immune imbalance which contribute to the development of uveitis. The search was limited to primary reports published in English with human subjects from 1990 to the present, yielding 3590 manuscripts. In addition, referenced articles from the initial searches were hand searched to identify additional relevant reports. After title and abstract selection, duplicate elimination, and manual search, 55 papers were selected for analysis and reviewed by the authors for inclusion in this review. Studies have demonstrated associations between various genetic factors and the development and clinical course of intraocular inflammatory conditions. Genes involved included genes expressing interleukins, chemokines, chemokine receptors, and tumor necrosis factor and genes involved in complement system. When considering the genetics of uveitis, common threads can be identified. Genome-wide scans and other genetic methods are becoming increasingly successful in identifying genetic loci and candidate genes in many inflammatory disorders that have a uveitic component. It will be important to test these findings as uveitis-specific genetic factors. Therefore, the burgeoning understanding of the human genome promises to result in new insight into the pathogenesis of uveitis.

Automated Analysis of Anterior Chamber Inflammation by Spectral-Domain Optical Coherence Tomography.

PURPOSE: This study was designed to determine the feasibility of anterior segment optical coherence tomography (AS-OCT) to objectively image and quantify the degree of AC inflammation. DESIGN: Prospective evaluation of a diagnostic test. PARTICIPANTS: Patients with anterior segment involving uveitis. METHODS: Observational case series of patients with uveitis. Single-line and 3-dimensional (3D) volume AS-OCT scans were manually graded to evaluate for the presence or absence of cells in the AC. Clinical grading scores were correlated to the number of cells seen in each line scan. An automated algorithm was developed to measure the number of cells seen in the 3D volume scan and compared with manual measurements and clinical grading scores. MAIN OUTCOME MEASURES: Degree of anterior segment inflammation. RESULTS: A total of 114 eyes from 76 patients were imaged, 83 eyes with line scans and 31 eyes with volume scans. The average number of cells on line scans was 0.13 for grade 0, 1.2 for grade 1/2+, 2.6 for grade 1+, 5.7 for grade 2+, 15.5 for grade 3+, and 41.2 for grade 4+. Spearman correlation coefficient comparing clinical grade with the individual AS-OCT line scans was 0.967 (P < 0.0001). The range of cells in the automated cell count of 3D volume scans was 13.60 to 1222; the range for manual cell counts was from 9.2 to 2245. The Spearman correlation coefficients were r = 0.7765 (P < 0.0001) and r = 0.7484 (P < 0.0001) comparing the manual and automated cell counts with the clinical grade, respectively. Spearman correlation coefficient comparing the automatic cell counts with manual cell count in the 3D volume scan was 0.997 (P < 0.0001). CONCLUSIONS: Anterior segment OCT can be used to image and grade the degree of AC inflammation. Clinical grading strongly correlates with the number of cells on AS-OCT line scans and volume scans. The automated algorithm to measure cell count had a high correlation to manual measurement of cells in the 3D volume scans. This modality could be used to objectively grade response to treatment.

Night blindness and Crohn's disease.

Signs of malnutrition are common clinical features in Crohn's disease; and bowel resection, commonly needed in these cases, can aggravate malnutrition. These patients are at risk of developing vitamin A deficiency, which can lead to night blindness. We present a 60-year-old male, with history of Crohn's disease and multiple resections for strictures and fistulas leading to short bowel syndrome, with progressive bilateral loss of night vision (nyctalopia). Serum vitamin A level was markedly depleted (11 µg/dL, reference 20-120 µg/dL), and full-field electroretinogram testing demonstrated extinguished scotopic (rod function) responses and decreased amplitudes of photopic responses on 30 Hz flicker (cone function). He was started on vitamin A supplementation (initially intramuscular). His vitamin A level was back to normal (78 µg/dL), and night vision problems subjectively improved. Patients with Crohn's disease should be inquired about night vision problems. The presence of nyctalopia should prompt vitamin A level measurement and ophthalmology referral for further evaluation.

Acute and chronic Staphylococcus epidermidis post-operative endophthalmitis: The importance of biofilm production.

To report two cases of acute and chronic-onset, postoperative Staphylococcus epidermidis endophthalmitis and discuss the virulence and treatment of this saprophytic pathogen. After clinical diagnosis of endophthalmitis, prompt vitreous culture was performed with injection of intravitreal vancomycin 1 mg/0.1 mL and ceftazidime 2.25 mg/0.1 mL. With no improvement after this procedure, a pars plana vitrectomy and lensectomy were performed to further decrease microbial load and repeat the intravitreal antibiotic. The lens and large amounts of fibrotic tissue were removed, and the posterior capsule was stripped. Vitreous cultures grew S. epidermidis sensitive to vancomycin. Intraoperative findings included dense vitreous opacification with extensive vitreous bands and pus extending into the zonules. During the removal of the IOL, adherent pus filaments were removed; however, only a moderate amount of bacteria was detected on the IOL. Further intravitreal vancomycin (1 mg/0.1 mL) and ceftazidime (2.25 mg/0.1 mL) were injected. Staphylococcus epidermidis is widely reported as responsible for medical device-related sepsis. This is mainly due to the production of slime, an exopolysaccharide that eventually leads to the formation of biofilm, one of the most important virulence factors. The failure of intravitreal antibiotic treatment in our two biofilm-associated infections may be due to the considerable amount of slime and pus found extending into the zonules and adherent to the IOL during surgery.

Imaging Characteristics and Clinical Utility of Half-Dose versus Full-Dose Ultrawidefield Fundus Fluorescein Angiography.

PURPOSE: In early 2022, a fluorescein shortage occurred in the United States. To meet the standard of care for patients who required ultrawidefield fundus fluorescein angiography (UWFFA), a regimen of half-dose (250 mg) sodium fluorescein (10%) was adopted instead of the full dose (500 mg) at the Cole Eye Institute (CEI). In this paper, we compare the image quality, clinical utility, and the side-effect profile of half-dose versus full-dose fluorescein in UWFFA for a cohort of stable patients. DESIGN: Retrospective chart review. PARTICIPANTS: Patients with retinal vascular disease were included if they received half-dose and full-dose UWFFA (Optos California) within 6 months at the CEI. Eyes were excluded if they received intraocular injections, laser procedures, new immunosuppression, and worsened or improved inflammation on clinical examination. METHODS: Quantitative assessment of vascular leakage was performed using a machine learning-enhanced automated segmentation platform. Leakage from late-phase UWFFA images was compared between half-dose and full-dose images. Qualitative assessment of image quality and relative vascular leakage was performed by 2 masked independent reviewers. Side effects after fluorescein administration were recorded for each patient. MAIN OUTCOME MEASURES: Masked leakage grading and automated leakage scores. RESULTS: There were 52 eyes of 35 patients, 42 (81%) uveitic, 5 (9%) diabetic, and 4 (8%) normal controls. Patients had no change to their visual acuity (logarithm of the minimum angle of resolution mean, 0.3 ± 0.6), anterior chamber and vitreous cell between UFFWA's. UWFFA images were deemed of equal quality and leakage by both masked reviewers (78%-87% agreement; κ, 0.642). Automated leakage analysis showed mildly increased leakage in half-dose images overall (3.8% vs. 2.8%; P = 0.01) and in the macula (1.5% vs. 0.6%; P = 0.01). Side effects included nausea (half [n = 3, 9%] vs. full [n = 2, 6%]; P = 0.69) and urticaria (n = 0, 0% vs. n = 1, 2%; P = 0.99) and were not different between doses. CONCLUSIONS: In this cohort, half-dose UWFFA produced images that were of similar quality, clinical utility and with a similar side effect profile compared with full dose. Half-dose UWFFA can be used to accurately assess the retinal vasculature and could be used primarily as a method to save cost and prevent waste.

Early treatment response of fluocinolone (retisert) implantation in patients with uveitic macular edema: an optical coherence tomography study.

PURPOSE: To analyze the early spectral domain optical coherence tomography changes after fluocinolone implantation in eyes with baseline uveitic macular edema. METHODS: Patients with uveitic macular edema and who received fluocinolone implantations by 2 surgeons (R.P.S. and J.E.S.) at the Cole Eye Institute (Cleveland Clinic, Cleveland, OH) from September 2009 to July 2010 were eligible for this study. Best-corrected visual acuity, intraocular pressure, central subfield thickness, cube volume, cube average thickness, and cystoid macular edema grade were recorded before implantation and in the early postoperative period (median: 3 months postimplantation). Changes in these variables were analyzed using the Wilcoxon signed-rank test for paired comparisons of clustered data. P values were 2 sided, and alpha was set at 0.05. RESULTS: Twelve eyes of seven patients were included in the study. The median best-corrected visual acuity improved in the early postoperative period after implantation (20/80 before implantation and 20/50 after implantation), but this improvement was not found to be significant (P = 0.12). However, the spectral domain optical coherence tomography measurements-central subfield thickness, cube volume, cube average thickness, and cystoid macular edema grade-were all significantly reduced (median changes: -234 µm [P = 0.02], -1 mm [P = 0.04], -39 µm [P = 0.04], and -3 [P = 0.03], respectively). CONCLUSION: Fluocinolone implantation is associated with a significant reduction in macular edema as measured by spectral domain optical coherence tomography in the early postoperative period, a result that is consistent with the proposed mechanism of the drug.

Bacillary Layer Detachment as a Presenting Feature of Ocular Sarcoidosis.

BACKGROUND AND OBJECTIVE: Bacillary layer detachment (BALAD) is a recently described finding on optical coherence tomography (OCT) that has been reported in a variety of uveitic and retinal diseases. To add to the growing literature on conditions associated with this finding, we report on the first cases of BALADs in ocular sarcoidosis. PATIENTS AND METHODS: Observational, retrospective chart review of patients with BALADs as a feature of sarcoid-associated uveitis. RESULTS: Three patients presented with blurry vision and bacillary layer detachments on OCT who were either known to have or found to have sarcoid-associated uveitis. All three patients had resolution of the BALAD and improvement in visual acuity with a combination of high-dose oral steroids and/or systemic immunosuppression. CONCLUSIONS: Patients presenting with BALAD should be assessed for sarcoidosis, if appropriate, given the systemic implications of this diagnosis.

Response to Acthar Gel in sarcoidosis uveitis: A prospective open label study.

PURPOSE: To investigate the response to Acthar Gel® in patients with moderate to severe sarcoidosis uveitis. METHODS: This is a prospective open-label study that enrolled patients with moderate to severe sarcoidosis uveitis to receive 80 units daily of Acthar Gel for ten days followed by maintenance treatment with 80 units twice weekly. The primary outcome was the proportion of patients meeting at least one of the following variables 1) improved visual acuity, 2) resolution of intraocular inflammation, 3) ability to taper ocular or oral steroids by at least 50% or 4) reduction of cystoid macular edema, with no worsening of any single measure and no need for additional sarcoidosis therapies at 24 weeks. RESULTS: A total of nine patients were enrolled in the study. Four patients completed the full 24-week course of Acthar Gel, and three of these met the primary endpoint. Among the five patients who did not complete the 24-week course of treatment, four discontinued the treatment due to worsening ocular inflammation. One patient discontinued treatment due to severe adverse effects. The most common adverse effects were fluid retention (77%), insomnia (44%), hypertension (44%) and hyperglycemia (44%). CONCLUSIONS: We observed a clinical response to Acthar Gel in some patients with moderate to severe sarcoidosis uveitis, but a substantial proportion either failed to respond or did not tolerate the therapy. These observations may serve as preliminary data for controlled trials of Acthar Gel, but they do not support its role prior to failure of other agents.

Relentless placoid chorioretinitis: A review of four cases in pediatric and young adult patients with a discussion of therapeutic strategies.

Introduction: Relentless placoid chorioretinitis (RPC) is a rare, bilateral disease of the retinal pigment epithelium. The clinical course is prolonged and relapsing. No standard treatment has been established to date. The purpose of this case series is to report four cases of RPC in pediatric and young adult patients in which varying treatments were used, comparing them to previously published cases. Methods: A literature review was conducted to investigate currently published presentations and treatment options for RPC. A multicenter retrospective chart review was also performed on four consecutive patients. These patients were diagnosed with RPC because of new chorioretinitis lesions continuing to appear without or despite therapy for 5-36 months (2 patients), with a clinical course prolonged and relapsing, or because of the atypical location of the multiple lesions (>50) extending from the posterior pole to the equator and mid-peripheral retina (all four patients), which were not consistent with other entities like acute posterior multifocal placoid pigment epitheliopathy and serpiginous choroiditis. Results: All four cases of RPC received oral or IV steroids acutely, and three of these patients were transitioned to a steroid-sparing agent and biologic therapy: anti-TNF alpha or anti-IL-6. Quiescence of the chorioretinitis lesions was obtained after 7 months, 1 month, and 36 months; however, the latter had issues with treatment adherence. Mycophenolate mofetil was insufficient to control the disease in one patient, but tocilizumab and infliximab thereafter were effective after cessation of adalimumab due to side effects. Adalimumab when started the first month after the presentation was effective in controlling the disease in one patient. After the failure of interferon-alpha-2a, one patient displayed long-term control with infliximab. One patient did not require a steroid-sparing agent after oral prednisone taper as there was no evidence of progression or recurrence. Conclusion: This case series adds to the current knowledge regarding potential treatments for RPC, specifically the use of anti-TNF-alpha treatment and anti-IL-6 tocilizumab. In this case study, relapses of RPC were found among patients on mycophenolate mofetil and interferon-alpha-2a, and one case did not relapse on oral steroids without a steroid-sparing agent. Our findings suggest that adalimumab, infliximab, and tocilizumab may be useful medications to obtain quiescence of RPC.

Ocular Syphilis With Phlebitis and Paravenous Pigmentary Retinopathy.

Purpose: Ocular syphilis can present as a wide variety of clinical phenotypes, among them panuveitis with vasculitis. Primary retinal phlebitis with resulting paravenous atrophy and pigmentary retinal degeneration is a rare presentation. Methods: A 53-year-old man presented with a 1-year history of bilateral blurry vision. Physical examination demonstrated bilateral anterior chamber and vitreous cell with vitreous haze, hyperemic optic nerves, and atrophic-appearing retina. The left eye demonstrated a nasal area of perivenular vascular sheathing with adjacent retinal whitening. Ancillary testing demonstrated predominantly perivenular leakage involvement. Results: Uveitic workup was positive for syphilis and HIV. The patient was treated with antiretroviral therapy and intravenous penicillin G. He developed progressive paravenous pigmentary changes and atrophy. Conclusions: Syphilis can present with a wide variety of phenotypic manifestations and should also be considered in patients presenting with acute retinal phlebitis or paravenous atrophy in long-standing cases.
