Purpose: The relative ellipsoid zone reflectivity (rEZR) is an innovative biomarker for photoreceptor alterations and showed association with disease staging in macular telangiectasia type 2 (MacTel). However, its prognostic relevance for the ellipsoid zone (EZ) loss is unclear.
Methods: Longitudinal spectral-domain optical coherence tomography (SD-OCT) imaging of patients with MacTel from an observational natural history study was used for en face determination of manifest EZ loss.
Article Synopsis
- - This retrospective study from the University of Bonn examined the frequency and characteristics of optic disc drusen (ODD) in patients with pseudoxanthoma elasticum (PXE) over a period from 2008 to 2023, analyzing data from 75 patients.
- - The findings revealed that 30.7% of the patients had ODD, which were predominantly localized nasally, and that those with ODD had significantly longer angioid streaks compared to those without ODD, indicating a potential correlation with ectopic calcification.
- - The study suggests that while only one patient developed new ODD and another had growth in existing ODD during the follow-up, the presence of ODD may have important
Purpose: To assess the onset, treatment frequency, and visual outcome of anti-vascular endothelial growth factor (anti-VEGF) treatment due to secondary choroidal neovascularization (CNV) in patients with pseudoxanthoma elasticum (PXE).
Design: Retrospective cohort study METHODS: One-hundred six eyes of 53 patients with PXE were analyzed. The assessment of CNV activity relied on hemorrhage visible on funduscopy and intra- / subretinal fluid on optical coherence tomography (OCT), individually defining a shortening or extension of treatment interval.
Purpose: To describe imaging features of macular telangiectasia type 2 eyes experiencing ellipsoid zone (EZ) recovery.
Methods: Macular telangiectasia type 2 patients with EZ recovery were identified from the Natural History and Observational Registry study and underwent retinal imaging including optical coherence tomography and fundus photography. Eyes were graded according to the classification system by Gass and Blodi, the EZ-loss area was measured, and optical coherence tomography parameters were assessed by two independent readers.
There are many insect pests worldwide that damage agricultural crop and reduce yield either by direct feeding or by the transmission of plant diseases. To date, control of pest insects has been achieved largely by applying synthetic insecticides. However, insecticide use can be seriously impacted by legislation that limits their use or by the evolution of resistance in the target pest.
