ABSTRACT
Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE) and serpiginous choroiditis are two diseases classified as "white spot syndromes." Both are inflammatory/autoimmune diseases with suspected primary involvement of the choriocapillaris. The former usually has an excellent prognosis, while the latter can rapidly induce legal blindness. Whereas these diseases are well defined and well known, other entities (such as persistent placoid maculopathy or ampiginous choroiditis) with features of both APMPPE and serpiginous choroiditis have been described more recently. This review aims to describe demographic characteristics and multimodal imaging features to help differentiate between these four diseases.

PURPOSE: To assess the carbon footprint of cataract surgery in a French university hospital. SETTING: Operating room of Cochin University Hospital, Paris, France. DESIGN: Single-center component analysis. METHODS: One day of surgery was used as a reference. Greenhouse gases (GHG) related to patient and staff transportation were calculated based on the distance travelled and the means of transportation used. The annual consumption of energy (heating and electricity) of our building was converted in kg equivalent of carbon dioxide (CO2eq), and the principle of proportionality was used to calculate what was used for a single cataract procedure. GHG emissions related to the life cycle assessment (LCA) of the equipment used and the sterilization process were calculated. RESULTS: The LCA of disposable items accounted for 59.49kg (73.32%) of CO2eq for each procedure. A single procedure generated 2.83±0.10kg of waste. The average CO2eq produced by the transportation of the patients to and from our center, adjusted for one procedure, was 7.26±6.90kg (8.95%) of CO2eq. The CO2eq produced by the sterilization of the phacoemulsifier handpiece was 2.12kg (2.61%). The energy consumption of the building and staff transportation accounted for the remaining CO2eq emissions, 0.76kg (0.93%) and 0.08kg (0.10%) respectively. Altogether, the carbon footprint of one cataract procedure in our center was 81.13kg CO2eq - the equivalent of an average car driving 800km. CONCLUSION: Our data provide a basis to quantify cataract surgery as a source of GHG and suggests that reductions in emissions can be achieved.

OBJECTIVE: We report on the case of a young immunocompetent female patient with parainfectious optic neuritis and macular inflitrate due to Neisseria meningitidis B meningitis. METHOD: Case report RESULTS: A 22-year-old female patient was admitted to the emergency department for intensive care treatment with a strong suspicion of meningitis. Clinical and serological parameters were indicative of a bacterial genesis of the meningitis. By analysis of the cerebrospinal fluid (CSF) Neisseria meningitidis type B could be detected. Subjective and objective symptoms could be improved by immediate intravenous administration of antibiotics; however, 1 day before discharge the patient complained of a sudden left-sided, painful loss of vision with extreme photophobia. The ophthalmoscopic examination revealed profound ciliary injection with slight anterior uveitis and papilledema with macular infiltration and diffuse petechiae-like retinal hemorrhage. After exclusion of viral proliferation in the CSF systemic steroid therapy was carried out together with continuation of antibiotic therapy and the eye was treated with local steroids and mydriatics. This resulted in healing of the ocular inflammation and partial recovery of vision. CONCLUSION: The painful loss of vision in this patient is probably due to parainfectious optic neuritis with macular infiltrate from Neisseria meningitidis B meningitis, which is an unusual course. Despite the rarity of this disease the complication of a parainfectious inflammation of the optic nerve should be considered and appropriate steps taken when the corresponding symptoms occur.
