RESUMEN
PURPOSE: The patterns of uveitis in Tokyo have recently changed due to advances in examination tools. We aimed to investigate the changes in the patterns of uveitis between 2004-2015 and 2016-2018. METHODS: We retrospectively reviewed the data of 732 patients who visited the Uveitis Clinic at the University of Tokyo Hospital between January 2016 and December 2018. Background characteristics, laboratory results, and imaging findings were analysed. We compared the incidences of uveitis in 2016-2018 and 2004-2015 to identify changes in the patterns. RESULTS: The most frequent diagnoses were sarcoidosis (8.9%), herpetic iridocyclitis (6.7%), intraocular lymphoma (5.5%), Vogt-Koyanagi-Harada disease (4.8%), unclassified acute anterior uveitis (4.6%), Behçet's disease (4.5%), bacterial endophthalmitis (2.9%), and Posner-Schlossman syndrome (2.6%). Suspected sarcoidosis (20.9%) was the most common cause of unclassified uveitis. The incidence of intraocular lymphoma was significantly higher in 2016-2018 than in 2004-2015. Between 2004 and 2018, herpetic iridocyclitis, bacterial endophthalmitis, and juvenile chronic iridocyclitis exhibited an increasing trend, and the incidences of Posner-Schlossman syndrome, unclassified acute anterior uveitis, Behçet's disease, and Vogt-Koyanagi-Harada disease exhibited a decreasing trend. CONCLUSION: The changing patterns of uveitis were characterised by increases in the incidence of intraocular lymphoma. This may be attributed to recent advances in examination tools, the changes in the referred patient population, and the aging Japanese population.

PURPOSE: To clarify the clinical features of uveitis in elderly patients in central Tokyo. METHODS: We retrospectively identified 1424 patients with uveitis who visited the Uveitis Clinic of the University of Tokyo Hospital between January 2013 and December 2018. The patients were categorized into two groups based on their ages at the time of disease onset: patients aged 65 years or older were included in Group A, whereas those younger than 65 years were included in Group B. The etiological classification of uveitis and its causes were investigated for each group. RESULTS: Group A presented significantly higher rates of infectious uveitis (35.5% vs. 17.8%, p < 0.0001) and masquerade syndromes (17.9% vs. 5.0%, p < 0.0001) than Group B. Furthermore, Group A had significantly higher rates of sarcoidosis (23.1% vs. 9.3%, p < 0.0001), intraocular lymphoma (16.6% vs. 4.6%, p < 0.0001), cytomegalovirus iritis (11.0% vs. 5.6%, p = 0.0043), and cytomegalovirus retinitis (5.2% vs. 1.5%, p = 0.0020) than Group B. CONCLUSION: Our results demonstrate a clear difference in the causative diseases of uveitis between elderly and non-elderly patients. These findings may support ophthalmologists in their diagnostic process for elderly patients with uveitis.

PURPOSE: To clarify the prevalence of secondary glaucoma (SG) and its speed of progression in patients with herpes simplex virus (HSV)-anterior uveitis (AU), varicella zoster virus (VZV)-AU, and cytomegalovirus (CMV)-AU. METHODS: In total, 170 patients with herpetic AU were enrolled in this retrospective observational case series. Patients with visual field (VF) defects and glaucomatous disc abnormalities were diagnosed with SG. Moreover, the speed of SG progression was defined as decreasing mean deviation (MD) values per year. SG prevalence and annual MD-value decrease were compared among the three types of herpetic AU. RESULTS: SG prevalence was 16%, 9%, and 72% in patients with HSV-AU, VZV-AU, and CMV-AU, respectively. Patients with CMV-AU had the highest SG prevalence (odds ratio = 3.15; 95% confidence interval = 1.15-8.65; P < 0.05). Furthermore, the annual MD-value change was significantly higher in SG caused by CMV-AU than in that caused by HSV/VZV-AU (-2.6 ± 2.4 dB/year and -0.45 ± 0.54 dB/year, respectively; P < 0.05). CONCLUSIONS: Our results demonstrated that patients with CMV-AU may have a higher risk and faster speed of progression of SG than patients with HSV/VZV-AU. Therefore, clinicians should monitor glaucoma onset and VF-defect progression in patients with CMV-AU.

PURPOSE: To investigate the clinical features of patients with ocular inflammation associated with relapsing polychondritis in Japan. METHODS: Ocular findings, systemic symptoms, and therapies were analysed retrospectively. RESULTS: Nine of 11 patients had scleritis (diffuse scleritis: six patients, posterior scleritis: two patients, episcleritis: one patient) and two patients had anterior uveitis. All cases were bilateral, and ten patients experienced recurrent episodes. Auricular chondritis was the most common systemic symptom. Ten patients were administered systemic steroids, and five patients were administered other immunosuppressive medications for severe systemic symptoms. At their last visit, none of the patients had decreased visual acuity that resulted from relapsing polychondritis-associated ocular inflammation. CONCLUSIONS: Ocular inflammation is often bilateral and recurring. Patients with ocular inflammation must be questioned regarding systemic symptoms so that the signs of relapsing polychondritis are not overlooked. Early diagnosis and prompt, appropriate treatment are important because relapsing polychondritis is a potentially lethal disease.

BACKGROUND: Fuchs' uveitis (FU) is occasionarlly complicated with heavy vitreous opacity. We have performed vitrectomy procedures to remove vitreous opacity in affected patients as part of differential diagnosis for primary vitreoretinal lymphoma (PVRL). CASE PRESENTATION: We retrospectively reviewed the clinical records of five patients who first visited the Uveitis Clinic of the University of Tokyo Hospital between 2009 and 2013, were diagnosed with FU and underwent a vitrectomy for removal of dense vitreous opacity. All were diagnosed as FU by ocular findings and elevation of Goldmann-Witmer coefficient (GWC) value for the rubella virus (RV) antibody. In examinations of the vitreous body, cytological diagnosis, elevation of IL-10/IL-6 ratio, and the kappa/lambda ratio in flow cytometry findings were negative in all cases, whereas monoclonal immunoglobulin heavy chain (IgH) gene rearrangement was positive in 4 cases and negative in 1 case. CONCLUSIONS: Although monoclonal IgH gene rearrangement is thought to be a reliable biomarker for PVRL, a high percentage of vitreous specimens from our FU patients showed pseudo-positive results. Ophthalmologists must take care regarding possible pseudo-positive findings when performing differential diagnosis between FU and PVRL. Combinations of results of cytological diagnosis, IL-10/IL-6 ratio, kappa/lambda ratio, and IgH gene rearrangement may be necessary for a definitive diagnosis of PVRL and differentiation from FU.

PURPOSE: To investigate the clinical features of psoriatic uveitis in Japanese patients. METHODS: Clinical features of 13 consecutive patients with psoriatic uveitis treated at our facility were retrospectively examined using medical records. In this study, we collected data about psoriasis type, uveitis laterality, onset type, HLA types, visual acuity, ocular inflammation localization, anterior segment findings, funduscopy findings, complications, recurrence, and medical treatments for uveitis and skin diseases. RESULTS: The cohort comprised ten males and three females (43.6 ± 7.1 years old), and types of psoriasis included psoriasis vulgaris (seven cases), psoriatic arthritis (four cases), pustular psoriasis (three cases) and psoriatic erythroderma (one case). Two cases represented complicated cases of pustular psoriasis and psoriatic arthritis. Seven cases were unilateral, and six cases were bilateral. All cases had acute non-granulomatous anterior uveitis, whereas panuveitis occurred in one case. Furthermore, macular edema and vascular leakage on fluorescein angiography occurred in four cases, and hyperemic disc occurred in two cases. Recurrence occurred in nine cases. In addition to topical corticosteroid treatment, eight cases underwent oral immunosuppressive treatment or biologics. All six cases undergoing HLA typing were HLA-A2 positive. CONCLUSIONS: Cases of psoriatic uveitis in Japan appear to present with acute non-granulomatous uveitis; other symptoms may include macular edema, retinal vasculitis, or hyperemic disc.

PURPOSE: To evaluate the long-term efficacy and safety of infliximab for the treatment of uveitis in Behçet's disease (BD). DESIGN: Retrospective multicenter study using a questionnaire. PARTICIPANTS: A total of 164 consecutive patients with BD treated with infliximab for more than 1 year were studied. The mean age at initiation of infliximab treatment was 42.6±11.7 years, and the mean treatment duration was 32.9±14.4 months. METHODS: Data before and at the last visit during infliximab treatment were analyzed in 4 groups divided by duration of treatment: group A (n = 43, 12-<24 months), group B (n = 62, 24-<36 months), group C (n = 42, 36-<48 months), and group D (n = 17, ≥48 months). MAIN OUTCOME MEASURES: Best-corrected visual acuity (BCVA), relapse of ocular inflammation, numbers of ocular inflammatory attacks per year, and adverse effects of infliximab therapy. RESULTS: The frequency of ocular attacks decreased in all groups (from 5.3±3.0 to 1.0±0.3 in group A, 4.8±4.6 to 1.4±0.3 in group B, 4.1±2.9 to 0.9±0.3 in group C, and 9.5±5.8 to 1.6±0.5 in group D; all P < 0.05). The BCVA was improved in approximately 55% of the eyes after treatment. Mean BCVA converted to logarithm of the minimum angle of resolution was improved after treatment with infliximab in groups A to C (from 0.79±1.04 to 0.59±0.94 in group A, 0.59±1.07 to 0.41±1.04 in group B, and 1.15±1.77 to 0.92±1.73 in group C; all P < 0.05) but not in group D. Uveitis relapsed in 59.1% of all patients after infliximab treatment, and no difference in duration until relapse was observed between individual groups. Approximately 80% of relapses occurred within 1 year after the initiation of infliximab treatment in all groups, 90% of which were controlled by increasing doses of topical corticosteroids and shortening the interval of infliximab infusion. Adverse effects were observed in 65 cases or 35% of all subjects. Infliximab treatment was continued in 85% of the patients, but 15% of the patients discontinued infliximab treatment because of adverse effects or insufficient efficacy. CONCLUSIONS: Infliximab reduced the frequency of ocular attacks and improved visual acuity in patients with BD-related uveitis and was generally well tolerated with few serious adverse events.

Purpose: To investigate the clinical features and visual outcome of young Japanese patients with uveitis.Methods: Patients younger than 18 years who presented with uveitis at the University of Tokyo Hospital between 2000 and 2018 were retrospectively reviewed.Results: The study comprised 98 patients whose mean age was 12.3 ± 3.8 years. Anterior uveitis was present in 52.0%, panuveitis in 37.8%, and posterior uveitis in 10.2%. The most common diagnosis was juvenile chronic iridocyclitis (JCI) (29.6%) followed by tubulointerstitial nephritis and uveitis syndrome (4.1%) and neuroretinitis (4.1%). Thirty-nine patients received systemic anti-inflammatory treatment. Among all subjects, 56% presented with ocular complications and 20% underwent ocular surgery. Visual acuity of 20/200 or less was observed in 6.2%. The common causes of decreased vision were hypotony, serous retinal detachment, and pupil disorder.Conclusions: JCI was the most common diagnosis. Hypotony, serous retinal detachment, and pupil disorder can lead to visual loss.

Purpose: To clarify the relationship between fluorescein angiography (FA) leakage after infliximab therapy and ocular attack relapse in patients with ocular Behçet's disease (BD). Methods: Patients with ocular BD were divided into two groups based on the presence (Group 1) or absence (Group 2) of ocular attacks after IFX therapy. FA leakage was evaluated by FA score in each of the optic discs, macula, large retinal vessels, and capillary vessels. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the relationship between FA score after IFX therapy and ocular attack relapse. Results: The areas under the curves obtained from the ROC curve of optic disc score and capillary vessels score after IFX therapy were 0.867 (95% confidence interval [CI]: 0.788-0.946) and 0.788 (95% CI: 0.649-0.927), respectively. Conclusions: FA leakage in the optic disc and capillary vessels after IFX therapy was strongly related to ocular attack relapse.

PURPOSE: Retinal vasculitis and occlusive changes are important signs of posterior uveitis and are possible diagnostic markers for uveitis. However, the frequency of arteritis and phlebitis in various uveitis entities, including infectious uveitis (IU) and non-infectious uveitis (NIU), have not been systematically investigated. STUDY DESIGN: Retrospective. METHODS: We investigated the frequency of retinal vascular inflammatory and occlusive changes in patients with IU and NIU. The study included 283 patients with intermediate, posterior, or pan-uveitis who were diagnosed with IU (presumed tuberculous uveitis, acute retinal necrosis, cytomegalovirus retinitis, human T-cell lymphotropic virus type 1-associated uveitis, toxoplasmic retinitis, syphilitic uveitis, rubella virus-associated uveitis, fungal endophthalmitis, and bacterial endophthalmitis) or NIU (sarcoidosis, Behçet's disease, Vogt-Koyanagi-Harada disease, human leukocyte antigen-B27-associated uveitis, systemic lupus erythematosus retinopathy, psoriatic uveitis, rheumatoid arthritis/collagen disease-associated uveitis, multiple sclerosis-associated uveitis, and sympathetic ophthalmia). All patients underwent fluorescein angiography (FA) and color photography examinations of the fundus. Presence of inflammatory and occlusive changes was determined by FA images. RESULTS: Significantly higher positive ratios of phlebitis, vein sheathing, vein occlusion, arteritis, artery sheathing, artery occlusion, and avascular areas were observed in the IU group than in the NIU group (p < 0.05). Notably, the discrepancy between IU and NIU was prominent with regard to retinal arterial changes (arteritis [57.9% vs 11.2%], inflammatory artery sheathing [33.7% vs 0%], and artery occlusion [22.1% vs 3.7%], respectively; p < 0.0001). CONCLUSION: Findings of vasculitis and occlusion, especially in retinal arteries, in FA strongly suggest an infectious origin of active uveitis.

This study aimed to clarify the association between the retinal leakage site on fluorescein angiography (FA) and subfoveal choroidal thickness (SCT) measured using enhanced depth imaging optical coherence tomography (EDI-OCT). Twenty-two patients with Behçet's uveitis were retrospectively selected in this study. They underwent EDI-OCT and FA in both the active and convalescent phases. The associations of the changes between the active and convalescent phases in SCT and in FA leakage in various retinal areas (total retina, peripheral retina, macula, and optic disc) were examined. The changing rates of SCT between the two investigated phases were significantly associated with the changes in total FA leakage scores (y = 1.79X+ 11.7, r2 = 0.210, p < 0.05). Furthermore, the changes in FA leakage scores in the macula were correlated with the changing rates in SCT (y = 3.72X+ 13.9, r2 = 0.219, p < 0.05). By contrast, there were no significant associations between the changes in SCT and those in leakage from the peripheral retina or the optic disc on FA. These findings demonstrate that SCT may reflect macular vasculitis as determined using FA, and SCT measurement could be a non-invasive method to investigate inflammation near the macula in Behçet's uveitis.

PURPOSE: To investigate the clinical characteristics of Japanese patients with scleritis STUDY DESIGN: Retrospective study METHODS: The clinical records of 123 patients with scleritis, who presented to the University of Tokyo Hospital between January, 2004 and December, 2015, were retrospectively reviewed. RESULTS: The cohort comprised 55 men and 68 women (mean age, 57.8±16.4 years), of which 76 showed anterior diffuse scleritis, 17 showed anterior nodular scleritis, 10 showed anterior necrotizing scleritis, and 20 showed posterior scleritis. The underlying etiology was identified in 39 patients. Autoimmune diseases were present in 32 patients, including eight with rheumatoid arthritis, seven with antineutrophil cytoplasmic antibody-associated vascular disease, and six with relapsing polychondritis. Ocular hypertension was the most common ocular complication (41%), followed by anterior chamber cells (38%). Fifty-three percent of patients required systemic immunosuppressive medication. Systemic corticosteroids were the most commonly used medication (45%), followed by methotrexate (11%). A, decrease in vision was observed in one-third of patients with anterior necrotizing scleritis or posterior scleritis, of which secondary glaucoma and optic neuritis were the major causes. CONCLUSION: Autoimmune diseases were present in 26% of patients. One-third of patients with anterior necrotizing scleritis or posterior scleritis experienced decreased vision, mostly due to secondary glaucoma and optic neuritis. Therefore, controlling intraocular pressure by methods such as administration of steroid-sparing immunosuppressive medication and appropriate treatment for posterior scleritis are essential for scleritis treatment.

PURPOSE: To investigate the frequency of conditions of newly arrived patients with uveitis from 2010 to 2012 and compare this frequency with that since 2004. METHODS: We retrospectively analyzed clinical records of patients who visited the outpatient clinic from January 2010 to December 2012, and compared them with those from 2004-2009. RESULTS: From 2010 to 2012, 695 new patients with uveitis visited Tokyo University Hospital, with a definite diagnosis made in 431 (62.0%). The most common diagnosis was scleritis (8.3%), followed by sarcoidosis (8.1%); herpetic iridocyclitis (5.5%); Behçet disease (4.6%); Vogt-Koyanagi-Harada disease (4.0%); acute anterior uveitis (3.7%); Posner-Schlossman syndrome (3.6%); intraocular malignant lymphoma (3.0%); and bacterial endophthalmitis (1.9%). The most frequent unclassified type of uveitis was sarcoidosis-suspected (14.8%). CONCLUSIONS: When compared with years 2004-2009, the present series showed an increasing trend of intraocular malignant lymphoma, bacterial endophthalmitis, and chronic iridocyclitis, and a notable increase in chronic iridocyclitis in young girls, with decreasing trends of scleritis and Vogt-Koyanagi-Harada disease.

PURPOSE: To examine clinical outcomes following an initial trabeculectomy with mitomycin-C for secondary glaucoma associated with uveitis in Behçet disease (BD) patients. DESIGN: Retrospective interventional case series. PATIENTS AND METHODS: Twenty-two eyes in 18 patients with uveitic glaucoma (UG) associated with Behçet disease who underwent an initial trabeculectomy with mitomycin-C between January 1996 and August 2014 were retrospectively reviewed. The main outcome measures were intraocular pressure (IOP) control, persistence of a filtering bleb, incidence of postoperative complications, and preopertaive and postoperative frequency of uveitic attacks. We analyzed persistence rates using Kaplan-Meier life tables based on 3 definitions of target IOP control (≤21, ≤18, ≤15 mm Hg) and filtering bleb persistence. RESULT: The persistence rates of postoperative IOP at ≤21, ≤18, and ≤15 mm Hg at 5 years after surgery were 76.1%, 71.5%, and 68.1%, respectively, whereas that of a filtering bleb was 54.4%. Hypotony as a postoperative complication was observed in 4 (18.2%) cases. No significant difference was observed between the preoperative and postoperative frequency of uveitic attacks (1.36±1.15 vs. 0.95±1.49 times/y, P=0.16). There was 1 case in which recurrence of uveitis after surgery caused a loss of filtering bleb, which required a reoperation. CONCLUSIONS: At 5 years after surgery, the persistence rate of postoperative IOP control (≤21 mm Hg) was 76.1% and that of a filtering bleb was 54.4%. The frequency of uveitis recurrence did not significantly increase after surgery. Attention must be paid to avoid such recurrence to maintain the filtering bleb.
