Background: A case study is proposed to empirically test and discuss the eye-tracking status-quo hardware capabilities limitations of an off-the-shelf virtual reality (VR) headset with embedded for at-home ready-to-go online usability in ophthalmology applications. Methods: The data quality HTC Vive Pro Eye investigated novel testing specific objective VR perimetry. Testing was done across a wi...

OBJECTIVE To compare the results obtained by a new ultra-short automated perimetry test known as Tendency-Oriented Perimetry (TOP), which is an algorithm based on estimation of thresholds from information gathered from adjacent points with those obtained by a standard bracketing approach. TOP is designed to save up to 1/5 of the time taken by standard strategy by presenting each stimulus once o...

Purpose: Reductions in perimetry thresholds caused by glaucoma should be proportional to the losses of retinal ganglion cells that result from the disease. However, there is considerable variability in neural deficits underlying visual defects, especially for defects of less than 15dB and for those near the fovea. One of the potential sources of variability in the functional-neural relationship...

To determine the sensitivity and specificity of high-pass resolution perimetry ("ring test"), 18 patients with pseudotumor cerebri (PTC) and 18 age-matched controls were examined with the Humphrey program 24-2 and the ring test. Goldmann perimetry also was done to determine if defects found with the ring test were present with another method. Testing with Humphrey perimetry revealed defects in ...

OBJECTIVES To create a fully automated, combined perimetry program consisting of a static examination and a kinetic examination, and to compare the results of this test with standard static and kinetic visual fields (VFs). METHODS Fifty-six patients (74 eyes) undergoing neuro-ophthalmic or glaucoma evaluation who had standard static or kinetic perimetry examinations underwent the combined per...

PURPOSE The validity of clinical perimetry for evaluation of the pathology of glaucoma is based on correlated losses in retinal ganglion cells and visual sensitivity, but procedures to quantify neural losses from visual field defects have not been developed. The purpose of the present study was to investigate the neural and sensitivity losses from experimental glaucoma to establish the framewor...
