Purpose: To evaluate 18 F-fluorodeoxyglucose Positron Emission Tomography/ultra low dose Computed Tomography ( 18 F-FDG PET/ ULD CT) in the work-up of pediatric uveitis., Methods: Retrospective study of 12 children followed for uveitis who underwent whole body 18 F-FDG PET/ULD CT between 2011 and 2019., Results: The average age of the patients was 11 years. A total of 100% of patients presented with bilateral uveitis, 50% had panuveitis and 92% had various choroidal involvement. Relevant information for diagnosis was provided in four patients. 5/12 had an abnormal 18F-FDG uptake. Of these, three patients had pathognomonic images of active granulomatous diseases. Three patients underwent PET CT-guided biopsies of which two were positive for sarcoidosis., Conclusion: 18 F-FDG PET/CT provided important information for final diagnosis in approximately 30% (4/12) of pediatric patients with bilateral uveitis. Whole body FDG PET/ULD CT can contribute to the final diagnosis thanks to pathognomonic image of active granulomatous disease and/or by indicating metabolically active site of biopsy that would not be visualized in thorax CT.

Purpose: To describe subclinical chorioretinal lesions revealed by indocyanine green angiography (ICGA) and their evolution under systemic treatment in tubulointerstitial nephritis and uveitis (TINU) patients., Methods: Retrospective case series of three patients with TINU syndrome. Choroidal and retinal involvement were assessed by fluorescein angiography (FA) and ICGA., Results: Three patients were analyzed. FA demonstrated hot disc, associated in two cases with retinal vascular leakage, and ICGA revealed subclinical chorioretinal dots in all three cases. Given the presence of posterior uveitis and deterioration of kidney function, asystemic treatment by oral methylprednisolone was started. Persistence of retinal and choroidal inflammations under systemic corticosteroids required association with immunosuppressive agent to control the disease activity., Conclusion: Multimodal imaging and more precisely ICGA is useful to assess subclinical choroidal inflammation and monitor treatment response in TINU syndrome. Immunosuppression needs to be revised and adapted when uveitis and/or kidney function are unresponsive to systemic steroids., Abbreviations: TINU: tubulointerstitial nephritis and uveitis; TIN: tubulointerstitial nephritis; ACE: angiotensin-converting enzyme; RF: rheumatoid factor; Uβ2M: urinary β-2microglobulin; AMPPE: acute multifocal placoid pigment epitheliopathy; FA: fluorescein angiography; ICGA: indocyanine green angiography; CT: computed tomography.

Purpose: To evaluate the safety and efficacy of photodynamic therapy with verteporfin (PDT) for subfoveal classic choroidal neovascularization (CNV) related to punctate inner choroidopathy (PIC) or presumed ocular histoplasmosis-like syndrome (POHS-like)., Methods: Retrospective review of 16 eyes from 14 patients with subfoveal classic CNV associated with PIC or POHS-like and treated with PDT., Results: The mean visual acuity increased from 4.5/10 (range: 1/10-9/10) to 7/10 (range: 2/10-10/10) after a mean follow-up of 21 months (range: 8-32 months) and a mean number of 2 PDT (range: 1-6). Visual acuity remained stable or improved in 13 of the 16 eyes (81%) and decreased in three., Conclusion: This nearly two-year follow-up study suggests that PDT could be helpful for patients with subfoveal classic CNV related to PIC or POHS-like.

A patient with AIDS and cytomegalovirus (CMV) retinitis developed a massive bilateral peripheral occlusive vasculopathy with a bilateral neovascularization of the optic disc five weeks after the introduction of highly active antiretroviral therapy (HAART). No associate cause of occlusive vasculopathy was found. Occlusive vasculopathy and optic disc neovascularization may be an immune recovery-related ocular disorder.

The use of highly active antiretroviral therapy (HAART) has dramatically modified the natural history of cytomegalovirus retinitis (CMVR) in AIDS patients. In this context, we discontinued maintenance therapy in eight AIDS patients with previous CMVR and a good and persistent immune and virological response to HAART (CD(4) >/= 75/mm(3) in all patients, viral load
