[Optometric eye screening in schools : First results of a pilot project on logistical feasibility].

Background: We present a pilot project to improve eye health in schoolchildren: annual optometric screening with a focus on early detection of school myopia. The logistical proof-of-concept is illustrated by way of a pilot project at a state high school in North Rhine-Westphalia. The collected biometric parameters also contribute to the collection of epidemiological data.

Efficacy of nanosecond laser treatment in central serous chorioretinopathy with and without atrophy of retinal pigment epithelium.

Background: To evaluate the outcomes of subthreshold nanosecond laser treatment of chronic central serous chorioretinopathy (CSC) as a function of the severity of concomitant of retinal pigment epithelium (RPE) defects.

Methods: This retrospective study compares data from 23 CSC diagnosed eyes with only mild RPE defects (group 1), 16 CSC eyes with moderate RPE defects (group 2), and 17 CSC eyes having severe RPE defects (group 3). After subthreshold treatment with the standard Ellex 2RT™ nanosecond laser (Ellex Medical Lasers Ltd, Australia), changes in macular structure and levels of subretinal fluid (SRF) were assessed by OCT-SD, OCT-A, functional integrity of the retina was assessed by corrected distance visual acuity (CDVA) and microperimetry, each at baseline and 1, 3, 6, and 12 months after initial treatment; re-treatment took place in cases of persistent SRF .

[Nanosecond Laser Treatment in Chorioretinopathia Centralis Serosa without RPE Defects: A Retrospective Case Series].

Background: Chorioretinopathia centralis serosa (CCS) is a uni- or bilateral disease of the macula which is characterized by detachment of the neuro-sensory retina. The spontaneous resolution rate is 68% after four months and 84% after six months.

Purpose: To investigate the efficacy of subthreshold nanopulse laser treatment for central serous chorioretinopathy (CCS) in the absence of any atrophy in the retinal pigment epithelium (RPE).

Engineering a palette of eukaryotic chromoproteins for bacterial synthetic biology.

Background: Coral reefs are colored by eukaryotic chromoproteins (CPs) that are homologous to green fluorescent protein. CPs differ from fluorescent proteins (FPs) by intensely absorbing visible light to give strong colors in ambient light. This endows CPs with certain advantages over FPs, such as instrument-free detection uncomplicated by ultra-violet light damage or background fluorescence, efficient Förster resonance energy transfer (FRET) quenching, and photoacoustic imaging.
