Functional and anatomical outcomes of fovea on, fovea off and fovea-splitting rhegmatogenous retinal detachment.

Purpose: To compare the anatomical and functional outcomes of fovea-on, fovea-off, and fovea-split rhegmatogenous retinal detachment (RRD).

Methods: Retrospective case series of consecutive patients diagnosed with RRD and treated with only pars plana vitrectomy (PPV). Preoperative and postoperative optical coherence tomography (OCT) and functional outcomes were obtained prior to and 6 months after surgery.

Postponed care due to COVID-19 lockdown impact on visual acuity of retinal vein occlusion patients: a large cohort.

Purpose: To evaluate the impact of postponed care attributed to coronavirus disease (COVID-19) pandemic lockdowns on visual acuity and the number of anti-VEGF injections in patients with retinal vein occlusion (RVO).

Methods: A multicenter, retrospective study of consecutive RVO patients previously treated with anti-VEGF injections, which compared data from pre- (2019) and during (2020) COVID-19 lockdown period.

Results: A total of 814 RVO patients with a mean age of 72.

Maternal urinary tract infection during pregnancy and long-term infectious morbidity of the offspring.

Background: Urinary tract infection (UTI) is a common bacterial infection in pregnant women and is associated with adverse perinatal outcomes. We sought to investigate the long-term infectious outcomes of children to mothers who were diagnosed with UTI during their pregnancy.

Methods: A population-based cohort analysis was conducted at a single tertiary medical center.

A Dedicated Genetic Algorithm for Localization of Moving Magnetic Objects.

A dedicated Genetic Algorithm (GA) has been developed to localize the trajectory of ferromagnetic moving objects within a bounded perimeter. Localization of moving ferromagnetic objects is an important tool because it can be employed in situations when the object is obscured. This work is innovative for two main reasons: first, the GA has been tuned to provide an accurate and fast solution to the inverse magnetic field equations problem.

Ferromagnetic mass localization in check point configuration using a levenberg marquardt algorithm.

A detection and tracking algorithm for ferromagnetic objects based on a two stage Levenberg Marquardt Algorithm (LMA) is presented. The procedure is applied to localization and magnetic moment estimation of ferromagnetic objects moving in the vicinity of an array of two to four 3-axis magnetometers arranged as a check point configuration. The algorithms first stage provides an estimation of the target trajectory and moment that are further refined using a second iteration where only the position vector is taken as unknown.
