Prevalence and Severity of Corneal Guttata After Descemet Membrane Endothelial Keratoplasty.

Purpose: The postoperative occurrence of corneal guttae (CG) in patients after Descemet membrane endothelial keratoplasty (DMEK) can lead to a significant reduction in visual acuity (VA) with the subsequent need for repeat DMEK. Therefore, the aim of this study was to analyze the prevalence and clinical significance of CG in transplanted corneas after DMEK.

Methods: The prevalence and progression of CG after DMEK of 1657 patients were examined using endothelial specular microscopy images.

Linking repeated subjective judgments and ConvNets for multimodal assessment of the immediate living environment.

The integration of alternative data extraction approaches for multimodal data, can significantly reduce modeling difficulties for the automatic location assessment. We develop a method for assessing the quality of the immediate living environment by incorporating human judgments as ground truth into a neural network for generating new synthetic data and testing the effects in surrogate hedonic models. We expect that the quality of the data will be less biased if the annotation is performed by multiple independent persons applying repeated trials which should reduce the overall error variance and lead to more robust results.

Past and future impacts of land-use changes on ecosystem services in Austria.

Environmental and socio-economic developments induce land-use changes with potentially negative impacts on human well-being. To counteract undesired developments, a profound understanding of the complex relationships between drivers, land use, and ecosystem services is needed. Yet, national studies examining extended time periods are still rare.
