BackgroundThe COVID-19 pandemic has significantly changed practice of medicine and patient care worldwide. The impact of the pandemic on patients with uveitis is unknown. We developed the COVID-19 Practice Patterns Study Group to evaluate the effect of the pandemic on uveitis patient care.MethodsThis is a multicentre, cross-sectional survey of uveitis specialists practising worldwide. A web-based survey was distributed through the mailing lists of international uveitis societies to assess modifications in patient care, and use of immunomodulatory therapies (IMTs),aswell as considerations regarding COVID-19 vaccination.ResultsA diverse group consisting of 187 uveitis specialists from six continents participated in this survey. Most of these experts noted a disruption in clinical management of patients, including clinic closures or decrease in volume, patients missing in-person visits due to the fear of infection and difficulties obtaining laboratory testing. Most participants initiated (66.8%) and continued (93.3%) IMTs based on clinical presentation and did not modify their use of immunosuppressives. In cases of reported exposure to COVID-19 infection, most participants (65.3%) recommended no change in IMTs. However, 73.0% of the respondents did recommend holding all or select IMTs in case of COVID-19 infection. COVID-19 vaccine was recommended universally by almost all the specialists and 52% stated that they would counsel patients regarding the decreased immunogenicity and effectiveness of the vaccine in immunocompromised patients.ConclusionsUveitis patient care has changed significantly since the beginning of the pandemic. The recommendations will continue to evolve as new data on IMTs and vaccination become available.

BackgroundImmunomodulatory therapy (IMT) is often considered for systemic treatment of non-infectious uveitis (NIU). During the evolving coronavirus disease-2019 (COVID-19) pandemic, given the concerns related to IMT and the increased risk of infections, an urgent need for guidance on the management of IMT in patients with uveitis has emerged.MethodsA cross-sectional survey of international uveitis experts was conducted. An expert steering committee identified clinical questions on the use of IMT in patients with NIU during the COVID-19 pandemic. Using an interactive online questionnaire, guided by background experience and knowledge, 139 global uveitis experts generated consensus statements for IMT. In total, 216 statements were developed around when to initiate, continue, decrease and stop systemic and local corticosteroids, conventional immunosuppressive agents and biologics in patients with NIU. Thirty-one additional questions were added, related to general recommendations, including the use of non-steroidal anti-inflammatory drugs (NSAIDs) and hydroxychloroquine.ResultsHighest consensus was achieved for not initiating IMT in patients who have suspected or confirmed COVID-19, and for using local over systemic corticosteroid therapy in patients who are at high-risk and very high-risk for severe or fatal COVID-19. While there was a consensus in starting or initiating NSAIDs for the treatment of scleritis in healthy patients, there was no consensus in starting hydroxychloroquine in any risk groups.ConclusionConsensus guidelines were proposed based on global expert opinion and practical experience to bridge the gap between clinical needs and the absence of medical evidence, to guide the treatment of patients with NIU during the COVID-19 pandemic.

Purpose: To report the clinical features and treatment outcomes in adult Caucasians with ocular toxocariasis (OT) and investigate their prognosis depending on their serological status. Methods: Retrospective observational cohort study (2016–2021) including consecutive adults with uveitis and positive western blot (WB) in the aqueous humor or vitreous. The presence of serum antibodies was not necessary for inclusion, allowing to compare the outcomes depending on the serological status. Results: Seventeen eyes of 15 patients were included. Mean age at diagnosis was 51.9 years. Vitreous inflammation was the most frequent sign (100%). Vitreoretinal tractions (41.2%) and chorioretinal granulomas (58.8%) were less prevalent. Atypical features were: spontaneous intravitreal hemorrhage (23.5%), exudative retinal detachment (11.8%), isolated macular edema (17.6%), papillitis (29.4%) and vasculitis (47.1%). Twenty percent of patients had a positive serum serology. Baseline clinical features did not differ statistically depending on the serological status; however, the degree of inflammation was numerically higher in patients with negative serology. Overall, macular thickness, anterior and posterior segment inflammation improved significantly after treatment with oral albendazole, systemic ± local corticosteroids. Vitrectomy (47.1%) was performed in case of persistent vitritis (62.5%), retinal detachment (12.5%) and intravitreous hemorrhage (25%). Conclusion: OT has no pathognomonic sign and atypical presentations were not infrequent in this adult Caucasian cohort. Serum antibodies were rarely positive, stressing on the importance of ocular sample analysis, especially in case of atypical features. Serum antibodies may prove useful in forecasting the rapidity of inflammation clearance. Antiparasitic and anti-inflammatory treatment was safe and efficient in most cases. [ABSTRACT FROM AUTHOR]

To describe a case of T-cell prolymphocytic leukemia (T-PLL) masquerading as viral retinal necrosis (VRN). A 75-year-old-man with a history of T-PLL in complete remission complained of an acute vision loss in his right and only eye. Ophthalmic examination demonstrated the presence of anterior chamber cells, mild vitritis, and peripheral retinal whitening with intraretinal hemorrhages evocative of VRN. While the anterior chamber tap came back negative for HSV, VZV, and CMV, cytology performed on the aqueous humor described the presence of leukemic cells. T-PLL can rarely masquerade as a viral retinal necrosis. Diagnostic work-up should therefore always rule out the infectious causes of retinitis. Anterior chamber tap can sometimes prove useful in the diagnosis of T-PLL even in the absence of a hypopyon, avoiding the need for vitrectomy. [ABSTRACT FROM AUTHOR]

Purpose: Post-transplant lymphoproliferative disorder (PTLD) represents a spectrum of disorders associated with Epstein Barr Virus infection in up to 80% of cases in the setting of pharmacologic immunosuppression following hematopoietic stem cell or solid organ transplantation. Ocular involvement is a rare finding in PTLD. Observation: We report the case of a 38-year-old man who presented with unilateral retinal infiltrates as first manifestation of PTLD relapse. Diagnosis relied on the presence of EBV DNA in anterior chamber fluids and vitrectomy that showed the presence of a B cell clone. Systemic relapse of PTLD was detected 12 weeks after retinal findings. Treatment of ocular disease included systemic injections of rituximab and intravitreal injections of methotrexate, halting the extension of retinal infiltrates. Conclusion: Ocular involvement in PTLD is rare and needs to be acknowledged because it can precede a systemic relapse of the hematological condition.

Purpose: To evaluate the safety and efficacy of the fluocinolone acetonide implant (FAi, Iluvien® Horus pharma, Nice, France) in non-infectious uveitic macular edema (UME) and to approach the predictive factors of treatment response. Methods: This retrospective, multicenter real-life study included patients with chronic non-infectious UME who received intravitreal FAi after at least two dexamethasone implants (DEXi). Results: Twenty-six eyes from 22 patients (73.1% of females) were included. The mean age was 60.4 ± 16 years. The mean follow-up was 11.4 ± 2 months. The mean baseline best-corrected visual acuity (BCVA) was 0.43 ± 0.36 LogMAR, improving significantly after 1, 3, 6 and 12 months (all p < 0.05 vs. baseline). The mean baseline central macular thickness (CMT) was 429 ± 110 μm, improving significantly after 1, 3, 6 and 12 months (all p < 0.05 vs. baseline). Five eyes (19.2%) developed ocular hypertension during the follow-up, requiring initiation or strengthening of intraocular pressure lowering medication. The majority of eyes (77%) did not require any rescue DEXi during the available 12-month follow-up. The resolution of UME after DEXi seemed to predict the anatomical response after FAi. The baseline presence of a disorganization of the inner retinal layers (DRIL) and hyperreflective foci (HRF) were both associated with a higher likelihood of requiring rescue DEXi injections. Conclusion: FAi implantation led to a significant BCVA and CMT improvement with a good safety profile over the 12-month follow-up. Predictive factors of treatment outcomes seem to include the anatomical response to DEXi and the presence of DRIL and HRF at baseline. [ABSTRACT FROM AUTHOR]
