Visual field examination method using virtual reality glasses compared with the Humphrey perimeter
PURPOSE To present a visual field examination method using virtual reality glasses and evaluate the reliability of the method by comparing the results with those of the Humphrey perimeter. MATERIALS AND METHODS Virtual reality glasses, a smartphone with a 6 inch display, and software that implements a fast-threshold 3 dB step staircase algorithm for the central 24° of visual field (52 points)...
متن کاملVisual field examination using a video projector: comparison with Humphrey perimeter
PURPOSE To present a method of visual field examination using a video projector. Also, we compare our results with those of a Humphrey perimeter, which is accepted as standard in automated perimetry. MATERIALS AND METHODS Software implementing a full-threshold 4-2-step staircase algorithm for the central 30-2 of the visual field (76 points) has been developed and tested in nine eyes of seven ...
متن کاملSimplified automatic method for measuring the visual field using the perimeter ZERK 1
BACKGROUND Currently available perimeters have limited capabilities of performing measurements of the visual field in children. In addition, they do not allow for fully automatic measurement even in adults. The patient in each case (in any type of perimeter) has at his disposal a button which he uses to indicate that he has seen a light stimulus. Such restrictions have been offset in the presen...
متن کاملA comparison of global indices between the Medmont Automated Perimeter and the Humphrey Field Analyzer.
BACKGROUND Two commonly used perimeters in Australia are the Humphrey Field Analyzer II (HFA) and the Medmont Automated Perimeter (MAP). Each device describes the visual field in terms of numerical values called global indices; however, these values are not interchangeable between devices. This study was designed to directly compare the global indices of HFA and MAP visual fields. METHODS 63 ...
متن کاملHumphrey visual field analysis, visual field defects, and ophthalmic findings in patients with macro pituitary adenoma.
OBJECTIVE To evaluate the Humphrey visual field parameters in patients with pituitary adenoma and classify the visual field defects in this patient group. METHODS Forty primary pituitary adenoma patients underwent neuro-ophthalmological examination and Humphrey Perimetry 30-2 visual field test at Baskent University, Departments of Ophthalmology, and Neurosurgery, between 2003 and 2005. Global...
