Purpose: To validate a manual measurement protocol for quantifying retinal thickness (RT) using an optical coherence tomography (OCT) device in pathologic myopia patients.

Methods: The macular Cross Hair protocol of Stratus OCT3 (Carl Zeiss Meditec, Inc., Dublin, Calif., USA) was applied and manual RT gauging was performed using the caliper tool. Foveal and paramacular RT, located at 1 and 2 mm distances from the fovea in both vertical and horizontal scans, were measured. Three consecutive RT measurements were taken to assess measurement reliability. The within-subject coefficient of variation (CVw) and intraclass correlation coefficients (ICC) were calculated to validate the manual method.

Results: The mean axial length of the 29 eyes assessed was 28.28 ± 2.72 mm and the mean spherical refraction was -13.61 ± 6.68 diopters. CVw ranged from 0.86 to 8.73% and ICC varied from 0.81 to 0.98.

Conclusion: A manual RT measurement protocol could reliably be used in the daily clinic for assessing pathologic myopic patients when OCT software segmentation fails.

: Orthoebolaviruses and orthomarburgviruses are filoviruses that can cause viral hemorrhagic fever and significant morbidity and mortality in humans. The evaluation and deployment of vaccines to prevent and control Ebola and Marburg outbreaks must be informed by an understanding of the transmission and natural history of the causative infections, but little is known about the burden of asymptomatic infection or undiagnosed disease. This systematic review of the published literature examined the seroprevalence of antibodies to orthoebolaviruses and orthomarburgviruses in sub-Saharan Africa.

Stroke is a global health issue caused by reduced blood flow to the brain, which leads to severe motor disabilities. Measuring oxygen levels in the brain tissue is crucial for understanding the severity and evolution of stroke. While CT or fMRI scans are preferred for confirming a stroke due to their high sensitivity, Near-Infrared Spectroscopy (NIRS)-based systems could be an alternative for monitoring stroke evolution.
