Treatment of Noninfectious Uveitic Macular Edema with Periocular and Intraocular Corticosteroid Therapies: A Report by the American Academy of Ophthalmology.

PURPOSE: To review the evidence on the effectiveness and complications of periocular and intraocular corticosteroid therapies for noninfectious uveitic macular edema. METHODS: A literature search of the PubMed database was conducted last in December 2021 and a post-assessment search was conducted in March 2023. The searches were limited to articles published in English and no date restrictions were imposed. The combined searches yielded 739 citations; 53 articles were selected for inclusion because the studies (1) evaluated periocular corticosteroid injection, intraocular corticosteroid injection or implant, suprachoroidal corticosteroid injection, or a combination thereof for uveitic macular edema; (2) had outcomes that included visual acuity (VA) or macular edema assessed clinically or imaged by OCT or fluorescein angiography; and (3) included more than 20 patients. RESULTS: This assessment reviewed 23 articles that provided level I or level II evidence from 18 studies on the use of periocular, suprachoroidal, and intravitreal triamcinolone acetonide injections and intravitreal dexamethasone and fluocinolone acetonide implants or inserts in noninfectious uveitic macular edema. These reports consistently demonstrated that all investigated periocular and intraocular corticosteroid therapies improved VA, macular structure, or both. One comparative study showed that intravitreal triamcinolone acetonide injection and the dexamethasone intravitreal implant had effectiveness superior to that of periocular triamcinolone acetonide injection for these outcomes. As a group, the studies highlighted the potential for these therapies to elevate intraocular pressure and to accelerate cataract formation. CONCLUSIONS: The published literature provides high-quality evidence that periocular and intraocular corticosteroid therapies are effective and safe for the treatment of noninfectious uveitic macular edema. However, information on the relative effectiveness and complication rates across the different therapies is limited.

Optic Disc Edema Is an Under-Recognized Feature of Birdshot Chorioretinitis.

BACKGROUND: Optic disc edema is a feature of many ophthalmic and neurologic conditions. It remains an underappreciated feature of birdshot chorioretinitis (BSCR), leading to delay in diagnosis and treatment. The purpose of our study was to identify clinical features that are concomitant with optic disc edema and suggest a diagnosis of BSCR. METHODS: Retrospective multicenter case series of 29 patients who were referred to a neuro-ophthalmologist or uveitis specialist for evaluation of disc edema and were ultimately diagnosed with BSCR. RESULTS: Fifty-four eyes of 30 patients, from the practices of 15 uveitis specialists, met the eligibility criteria. In addition to disc edema, concomitant features in all patients included vitritis, chorioretinal lesions, and retinal vasculitis. Visual recovery to 20/40 or better occurred in 26 of 29 patients. Visual acuity remained 20/100 or worse in 2 patients previously diagnosed with idiopathic intracranial hypertension, 1 patient previously diagnosed with optic neuritis, and 1 patient for whom treatment was delayed for years, leading to optic disc atrophy. CONCLUSIONS: Optic disc edema is a presenting feature in some cases of BSCR. A diagnosis of BSCR should be considered when disc edema occurs with vitritis, chorioretinal inflammation, and retinal vasculitis. Patients should be referred to a uveitis specialist for treatment.

The Infectious Uveitis Treatment Algorithm Network (TITAN) Report 1-global current practice patterns for the management of Herpes Simplex Virus and Varicella Zoster Virus anterior uveitis.

AIMS: To present current expert practice patterns and to formulate a consensus for the management of HSV and VZV AU by uveitis specialists worldwide. METHODS: A two-round online modified Delphi survey with masking of the study team was conducted. Responses were collected from 76 international uveitis experts from 21 countries. Current practices in the diagnosis and treatment of HSV and VZV AU were identified. A working group (The Infectious Uveitis Treatment Algorithm Network [TITAN]) developed data into consensus guidelines. Consensus is defined as a particular response towards a specific question meeting ≥75% of agreement or IQR ≤ 1 when a Likert scale is used. RESULTS: Unilaterality, increased intraocular pressure (IOP), decreased corneal sensation and diffuse or sectoral iris atrophy are quite specific for HSV or VZV AU from consensus opinion. Sectoral iris atrophy is characteristic of HSV AU. Treatment initiation is highly variable, but most experts preferred valacyclovir owing to simpler dosing. Topical corticosteroids and beta-blockers should be used if necessary. Resolution of inflammation and normalisation of IOP are clinical endpoints. CONCLUSIONS: Consensus was reached on several aspects of diagnosis, choice of initial treatment, and treatment endpoints for HSV and VZV AU. Treatment duration and management of recurrences varied between experts.

The Infectious Uveitis Treatment Algorithm Network (TITAN) Report 2-global current practice patterns for the management of Cytomegalovirus anterior uveitis.

AIMS: To present current practice patterns in the diagnosis and management of Cytomegalovirus anterior uveitis (CMV AU) by uveitis experts worldwide. METHODS: A two-round modified Delphi survey with masking of the study team was performed. Based on experience and expertise, 100 international uveitis specialists from 21 countries were invited to participate in the survey. Variation in the diagnostic approaches and preferred management of CMV AU was captured using an online survey platform. RESULTS: Seventy-five experts completed both surveys. Fifty-five of the 75 experts (73.3%) would always perform diagnostic aqueous tap in suspected CMV AU cases. Consensus was achieved for starting topical antiviral treatment (85% of experts). About half of the experts (48%) would only commence systemic antiviral treatment for severe, prolonged, or atypical presentation. The preferred specific route was ganciclovir gel 0.15% for topical treatment (selected by 70% of experts) and oral valganciclovir for systemic treatment (78% of experts). The majority of experts (77%) would commence treatment with topical corticosteroid four times daily for one to two weeks along with antiviral coverage, with subsequent adjustment depending on the clinical response. Prednisolone acetate 1% was the drug of choice (opted by 70% of experts). Long-term maintenance treatment (up to 12 months) can be considered for chronic course of inflammation (88% of experts) and those with at least 2 episodes of CMV AU within a year (75-88% of experts). CONCLUSIONS: Preferred management practices for CMV AU vary widely. Further research is necessary to refine diagnosis and management and provide higher-level evidence.

Hospital Readmissions Among Persons With Human Immunodeficiency Virus in the United States and Canada, 2005-2018: A Collaboration of Cohort Studies.

BACKGROUND: Hospital readmission trends for persons with human immunodeficiency virus (PWH) in North America in the context of policy changes, improved antiretroviral therapy (ART), and aging are not well-known. We examined readmissions during 2005-2018 among adult PWH in NA-ACCORD. METHODS: Linear risk regression estimated calendar trends in 30-day readmissions, adjusted for demographics, CD4 count, AIDS history, virologic suppression (<400 copies/mL), and cohort. RESULTS: We examined 20 189 hospitalizations among 8823 PWH (73% cisgender men, 38% White, 38% Black). PWH hospitalized in 2018 versus 2005 had higher median age (54 vs 44 years), CD4 count (469 vs 274 cells/µL), and virologic suppression (83% vs 49%). Unadjusted 30-day readmissions decreased from 20.1% (95% confidence interval [CI], 17.9%-22.3%) in 2005 to 16.3% (95% CI, 14.1%-18.5%) in 2018. Absolute annual trends were -0.34% (95% CI, -.48% to -.19%) in unadjusted and -0.19% (95% CI, -.35% to -.02%) in adjusted analyses. By index hospitalization reason, there were significant adjusted decreases only for cardiovascular and psychiatric hospitalizations. Readmission reason was most frequently in the same diagnostic category as the index hospitalization. CONCLUSIONS: Readmissions decreased over 2005-2018 but remained higher than the general population's. Significant decreases after adjusting for CD4 count and virologic suppression suggest that factors alongside improved ART contributed to lower readmissions. Efforts are needed to further prevent readmissions in PWH.

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.

Incidence of and Risk Factors for Cataract in Anterior Uveitis.

PURPOSE: To estimate the incidence/risk factors for cataract in noninfectious anterior uveitis. DESIGN: Retrospective multicenter cohort study (6 US tertiary uveitis sites, 1978-2010). METHODS: Data were harvested by trained expert reviewers, using protocol-driven review of experts' charts. We studied cataract incidence-newly reduced visual acuity worse than 20/40 attributed to cataract; or incident cataract surgery-in 3923 eyes of 2567 patients with anterior uveitis. RESULTS: Cataract developed in 507 eyes (54/1000 eye-years, 95% CI 49-59). Time-updated risk factors associated with cataract included older age (≥65 vs <18 years: adjusted hazard ratio [aHR] 5.04, 95% CI 3.04-8.33), higher anterior chamber cell grade (P(trend)=0.001), prior incisional glaucoma surgery (aHR 1.86, 95% CI 1.10-3.14), band keratopathy (aHR 2.23, 95% CI 1.47-3.37), posterior synechiae (aHR 3.71, 95% CI 2.83-4.87), and elevated intraocular pressure ≥30 vs 6-20 mm Hg (aHR 2.57, 95% CI 1.38-4.77). Primary acute (aHR 0.59, 95% CI 0.30-1.15) and recurrent acute (aHR 0.74, 95% CI 0.55-0.98) had lower cataract risk than chronic anterior uveitis. Higher-dose prednisolone acetate 1%-equivalent use (≥2 drops/day) was associated with >2-fold higher cataract risk in eyes with anterior chamber cell grades 0.5+ or lower but was not associated with higher cataract risk in the presence of anterior chamber cells of grade 1+ or higher. CONCLUSIONS: Cataract complicates anterior uveitis in ∼5.4/100 eye-years. Several fixed and modifiable risk factors were identified, yielding a point system to guide cataract risk minimization. Topical corticosteroids only were associated with increased cataract risk when anterior chamber cells were absent or minimally present, suggesting their use to treat active inflammation (which itself is cataractogenic) does not cause a net increase in cataract incidence.

Intravitreal Therapy for Uveitic Macular Edema-Ranibizumab versus Methotrexate versus the Dexamethasone Implant: The MERIT Trial Results.

PURPOSE: To evaluate the effectiveness of 3 different intravitreal treatments for persistent or recurrent uveitic macular edema (ME): dexamethasone implant, methotrexate, and ranibizumab. DESIGN: Single-masked, randomized controlled clinical trial. PARTICIPANTS: Patients with minimally active or inactive uveitis and persistent or recurrent uveitic ME in one or both eyes. METHODS: Patients at 33 centers were randomized 1:1:1 to receive 1 of the 3 therapies. Patients with bilateral ME received the same treatment in both eyes. MAIN OUTCOME MEASURES: The primary outcome, measured at 12 weeks, was reduction in central subfield thickness (CST) expressed as a proportion of baseline (CST per CST at baseline) assessed with spectral-domain OCT by readers masked to treatment assignment. Secondary outcomes included improvement and resolution of ME, change in best-corrected visual acuity (BCVA), and elevations in intraocular pressure (IOP). RESULTS: One hundred ninety-four participants (225 eligible eyes) were randomized to dexamethasone (n = 65 participants and 77 eyes), methotrexate (n = 65 participants and 79 eyes), or ranibizumab (n = 64 participants and 69 eyes). All received at least 1 injection of the assigned treatment. At the 12-week primary outcome point, each group showed significant reductions in CST relative to baseline: 35%, 11%, and 22% for dexamethasone, methotrexate, and ranibizumab, respectively. Reduction of ME was significantly greater in the dexamethasone group than for either methotrexate (P < 0.01) or ranibizumab (P = 0.018). Only the dexamethasone group showed a statistically significant improvement in BCVA during follow-up (4.86 letters; P < 0.001). Elevations of IOP by 10 mmHg, to 24 mmHg or more, or both were more common in the dexamethasone group; IOP spikes to 30 mmHg or more were uncommon overall and were not significantly different among groups. Reductions in BCVA of 15 letters or more were more common in the methotrexate group and typically were attributable to persistent ME. CONCLUSIONS: At 12 weeks, in eyes with minimally active or inactive uveitis, dexamethasone was significantly better at treating persistent or recurrent ME than methotrexate or ranibizumab. Risk of IOP elevation was greater with dexamethasone, but elevations to levels of 30 mmHg or more were infrequent.

Birdshot Chorioretinitis in Patients Aged 80 and Older.

PURPOSE: To assess the manifestations of birdshot chorioretinitis (BSCR) in patients aged 80 and over. DESIGN: Among patients with BSCR followed in the CO-BIRD prospective cohort (ClinicalTrials.gov Identifier: NCT05153057), we analyzed the subgroup of patients aged 80 and over. METHODS: Patients were assessed in a standardized manner. Confluent atrophy was defined as hypoautofluorescent spots on fundus autofluorescence (FAF). RESULTS: We included 39 (8.8%) of the 442 enrolled CO-BIRD patients. The mean age was 83.8 ± 3.7 years. The mean logMAR BCVA was 0.52 ± 0.76, with 30 patients (76.9%) having 20/40 or better in at least one eye. Thirty-five (89.7%) patients were receiving no treatment. Confluent atrophy in the posterior pole, disrupted retrofoveal ellipsoid zone and choroidal neovascularization were associated with logMAR BCVA >0.3 (p < .0001). CONCLUSION: In patients aged 80 and over we observed a striking heterogeneity of outcomes, but most retained a BCVA that allowed them to drive.

TACROLIMUS FOR IMMUNOSUPPRESSION IN PATIENTS WITH NONINFECTIOUS INTERMEDIATE, POSTERIOR, OR PANUVEITIDES.

PURPOSE: To evaluate the effectiveness of tacrolimus in patients with noninfectious intermediate, posterior, or panuveitis needing a two-immunosuppressive-agent regimen. METHODS: Design: Retrospective cohort study. Setting: Two tertiary-care uveitis practices at academic medical centers. Patient population: Thirty-two patients with noninfectious intermediate, posterior, or panuveitides in whom single-agent immunosuppression was inadequate to effect successful corticosteroid sparing. Intervention: tacrolimus, added as the second immunosuppressive agent. Main outcome measure: successful corticosteroid sparing, defined as inactive uveitis at a dose of prednisone ≤7.5 mg/day. RESULTS: Active uveitis was present in 65.6% of patients at initiation of tacrolimus, and the median time to inactive uveitis was 1.5 months (95% confidence interval 1.2, 4.08). The median time to successful corticosteroid sparing was 3.9 months (95% confidence interval 1.41, 6.67), and by 6 months of follow-up successful corticosteroid sparing was achieved in 75% of patients. Tacrolimus was discontinued for side effects in five patients, three for tremor, and two for hyperglycemia. All side effects were reversible with tacrolimus discontinuation. CONCLUSION: Tacrolimus seems to have efficacy as a second immunosuppressive agent in two-immunosuppressive drug regimens, when a single agent does not permit successful corticosteroid sparing. Side effects were reversible with tacrolimus discontinuation.

Swept Source Optical Coherence Tomography Angiography Findings in Birdshot Chorioretinitis: A Cross Sectional Study of 21 Patients.

PURPOSE: Birdshot chorioretinitis (BSCR) is a form of posterior uveitis that is classically characterized by hypopigmented choroidal lesions outside of the major arcades. However, little is known about the extent of choroidal involvement in the macula. We aim to describe the vascular abnormalities observed at the level of the choriocapillaris (CC) in the maculae of BSCR patients, using swept source optical coherence tomography angiography (SS-OCTA). METHODS: A cross-sectional, observational study was conducted. Eligible patients underwent clinical examination and SS-OCTA imaging. The main outcome measures were the frequency of vascular abnormalities observed at the level of the CC on SS-OCTA and foveal choriocapillaris vascular density (CVD). RESULTS: Twenty-one patients were included, with a median age of 61.5 years. All patients had bilateral disease with a median disease duration of 6 years. All but one patient received systemic immunosuppressive drug therapy, and 19 patients had suppressed inflammation on treatment at the time of the SS-OCTA assessment. Of the 42 affected eyes, 39 (92.9%) had gradable SS-OCTA images, with a mean LogMAR visual acuity of 0.18 (Snellen equivalent 20/30). In total, 34 of 39 (87.2%) eyes had some degree of pathologic flow loss, and after controlling for patient age and disease activity, both worse VA and longer disease duration remained statistically significantly associated with reduced foveal CVD. CONCLUSIONS: Our findings suggest that pathologic CC flow loss in the macula is frequently encountered and may contribute to visual function decline in patients with BSCR. Further studies with longitudinal follow-up are needed to characterize the evolution of these areas of pathologic CC flow loss over time.
