HST survey of the Orion Nebula Cluster in the H$_2$O 1.4 $\mu$m absorption band: I. A census of substellar and planetary mass objects [PDF]

, 2020
In order to obtain a complete census of the stellar and sub-stellar population, down to a few M$_{Jup}$ in the $\sim1$ Myr old Orion Nebula Cluster, we used the infrared channel of the Wide Field Camera 3 of the Hubble Space Telescope with the F139M and ...

Correlation between the pressure-to-cornea index and both structural and functional measures of glaucoma

Indian Journal of Ophthalmology, 2014
Purpose: the pressure-to-cornea index (PCI) was proposed in order to integrate intraocular pressure and central cornea thickness as a single-risk factor for glaucoma. The purpose of this study was to correlate the PCI with a structural and two functional

A randomised controlled trial to compare the clinical and cost-effectiveness of prism glasses, visual search training and standard care in patients with hemianopia following stroke: a protocol [PDF]

, 2014
INTRODUCTION: Homonymous hemianopia is a common and disabling visual problem after stroke. Currently, prism glasses and visual scanning training are proposed to improve it.

Semi-automatic measurement of visual verticality perception in humans reveals a new category of visual field dependency

Brazilian Journal of Medical and Biological Research, 2011
Previous assessment of verticality by means of rod and rod and frame tests indicated that human subjects can be more (field dependent) or less (field independent) influenced by a frame placed around a tilted rod.
