The carbon footprint and wastage of intravitreal injections.

Purpose: The healthcare system emits greenhouse gas emissions and produces waste that in turn threatens the health of populations. The objective of our study was to measure the ecological threat related to intravitreal injections.

Methods: Emissions were separated into scope 2 corresponding to Heating, Ventilation and Air Conditioning (HVAC) of the building, and scope 3 corresponding to travels (patients and staff), and life cycle assessment (LCA) of medical devices (MD) and pharmaceutics.

Choroidal imaging in patients with Cushing syndrome.

Aims: Glucocorticoid intake is a well-established risk factor for central serous chorioretinopathy that belongs to the pachychoroid spectrum disease (PSD). The study aimed to assess the prevalence of PSD and analyse the choroidal phenotype in patients with Cushing syndrome.

Methods: A cross-sectional study was performed in Ophtalmopôle hôpital Cochin, Paris, France, with a systematic evaluation of hospitalized patients with Cushing syndrome, between November 2017 and July 2018.

Comparison of the Effect of Ranibizumab and Aflibercept on Changes in Macular Choroidal Thickness in Patients Treated for Diabetic Macular Edema.

Purpose: The aim of this study was to assess the effect of intravitreal injections (IVI) of ranibizumab and aflibercept on the choroidal thickness (CT) in patients with treatment-naive diabetic macular edema (DME) before and after monthly IVI. . Prospective monocenter study.

Choroidal Structural Changes in Patients with Birdshot Chorioretinopathy.

: To assess the choroidal vascularity index (CVI) in birdshot chorioretinopathy (BSCR) patients.: The CVI was calculated as the ratio of luminar area to the total subfoveal choroidal area on enhanced-depth imaging optical coherence tomography. Intraocular inflammation was defined by the presence of macular edema and/or vitritis and/or vasculitis and/or papillitis.

Long-term functional and anatomical evolution in surgically closed macular holes with internal limiting membrane peeling.

Introduction: The aim of this study was to describe the long-term evolution of macular retinal thickness and visual acuity in patients who present surgically closed full-thickness macular hole, operated by vitrectomy with internal limiting membrane peeling.

Methods: A retrospective observational study of patients operated for full-thickness macular hole with closure of the hole and at least 6 months of post-operative follow-up was performed. All patients had pars plana vitrectomy, peeling of the internal limiting membrane, gas filling and positioning.
