RESUMO

PURPOSE: To test the hypothesis that central drusen location is strongly linked with known Age-related Macular Degeneration (AMD) risk factors and risk of incident late AMD. METHODS: The Alienor study is a prospective population-based cohort study of residents of Bordeaux, France, followed from 2009 to 2017. On retinal photographs, we defined central drusen as at least one soft drusen (>63 µm) within 500 µm from fovea and pericentral drusen as at least one drusen 500-3000 µm from fovea, in the absence of any central drusen. Late AMD (atrophic and/or neovascular) was diagnosed using multimodal imaging. In total, 481 eyes were included in the analysis: 160 central and 321 pericentral. We investigated associations with systemic (age, sex, smoking, medical prescriptions, plasma concentrations of lipids and nutrients, UV exposure, blood pressure), ocular (retinal thickness, cataract extraction) and genetic risk scores (GRS). RESULTS: In multivariate logistic regression central drusen were associated with smoking (OR, 2.95 for smoking more than 20 pack-years, p = 0.02), HDL-cholesterol (OR, 1.57 for 1 standard deviation (SD) increase, p = 0.0048), pulse pressure (OR, 0.77 for 1 SD increase, p = 0.04), Age-Related Maculopathy Susceptibility 2 (ARMS2) GRS (OR, 1.42; 95% CI, 1.11-1.83) and complement GRS (OR, 1.55; 95% CI, 1.15-2.10). In Cox modelling, the central location of drusen (at baseline or during the follow-up) was associated with a 4.41-fold increased risk (95% CI,1.98-9.81) for an incident late AMD. CONCLUSION: Central drusen were strongly associated with AMD risk factors and incident late AMD, suggesting that it represents a key marker for AMD progression.

RESUMO

PURPOSE: To report a case series of 3 patients with choroidal granulomas due to Bartonella henselae infection in order to raise awareness about this etiology in the differential diagnosis of choroidal granulomas. METHODS, PATIENTS: A retrospective case series of patients with choroidal granulomas due to Bartonella henselae infection who consulted between 2018 and 2020. Data were collected from the medical records (demographics, visual acuity (VA), laboratory tests, treatment, imaging). RESULTS: Patients were a 48-year old man, a 14-year old girl and a 31-year old man. They all had a choroidal granuloma seen on optical coherence tomography (OCT) and angiography. The laboratory work-up revealed a positive serology for Bartonella henselae in all patients. CONCLUSION: On multimodal imaging choroidal granulomas in B Henselae appeared as single or multiple, uni or bilateral round yellowish lesions. Fluorescein and indocyanine green angiography of the granuloma showed respectively a late staining and a hypofluorescence. On EDI-OCT choroidal granuloma appeared as a round hyporeflective lesion in the choroid with a retinal elevation. The exclusion of other diagnosis, the natural course and the serology must lead the ophthalmologist to evoke the diagnosis.
