Test characteristics of point-of-care ultrasonography for the diagnosis of acute posterior ocular pathology.

Objectives: The objective of this study was to determine the test characteristics of point-of-care ultrasonography (POCUS) for the diagnosis of retinal tear (RT), retinal detachment (RD), posterior vitreous detachment (PVD), and vitreous hemorrhage (VH).

Design: A prospective observation study on a convenience sample of patients presenting to a tertiary care emergency general ophthalmology clinic was performed.

Participants: Adult patients with acute flashes/floaters or new visual field defects were included (n = 62).

Efficacy of SLO-Microperimetry and Humphrey for evaluating macular sensitivity changes in advanced glaucoma.

Objective: To compare the efficacy of scanning laser ophthalmoscope microperimetry (SLO-MP) and Humphrey visual fields in detecting macular sensitivity changes in advanced glaucoma.

Design: Prospective cohort study.

Participants: 25 patients with advanced primary open angle glaucoma and 2 consecutive abnormal Humphrey 10-2 SITA Standard visual field tests.

Determination of growth rate of microorganisms in broth from oxygen-sensitive fluorescence plate reader measurements.

A novel method utilizing the BD Oxygen Biosensor System has been developed to rapidly, simply, and accurately determine the growth rate of microorganisms in broth, with no needfor plate counts, standardized inocula, or technically difficult manipulations. The BD Oxygen Biosensor System incorporates an oxygen-sensitive material into the wells of standard Falcon microplates. The time response of this sensor monitored in afluorescence plate reader can be used to quantitate microbe growth.
