Study summary

The purpose of this research study is to investigate the effectiveness of a new rehabilitation for visual hemianopia. The study team believes a cross-modal rehabilitation technique delivered by a virtual reality system can help restore the visual field for subjects with homonymous hemianopia.

Read the detailed description

The study tests a novel rehabilitation system, translated from promising cross-modal rehabilitation animal research, that is the first treatment capable of restoring the visual field for hemianopia patients. This noninvasive technique uses a virtual reality device to deliver visual and auditory stimulus. The goals of this study are to obtain proof of concept and procure rehabilitation data to support the development of this novel rehabilitation treatment.

What researchers measure

Primary outcomes

  1. Humphrey Visual Field Perimetry

    The area of the subject's visual field measured by 30-2 Humphrey visual field (HVF) perimetry. Both left and right sides will be tested. The deficit side includes is the hemianopic side. The intact side is the non-hemianopic side. During the HVF test, light is projected into a white bowl with a standardized background light intensity to form a circular stimulus, around 30 cm away from the patient's eye. The overall field mapping technique used is a form of static perimetry, where a stimulus appears in various areas of the field of vision. The patient indicates when they can see the stimulus and the perimetrist then records the point where the stimulus was seen. These data points are used to determine the patient's visual field.

  27. Veterans Affairs Low Vision Visual Function Questionnaire-48 (VA LV VFQ-48)--Item Score

    The VA LV VFQ-48 is a self-report instrument designed to measure difficulty visually impaired persons have performing daily activities. The acceptable range for the average item score is \<= 2.34 (most difficult) and \>=-2.22 (least difficult). Scores out of this range indicate something other than visual impairment is governing the patient's responses. The Item Score is the average functional reserve of all the items in the questionnaire excluding items which were rated Unscored (Difficult / don't do for Non-Visual Reasons). Functional reserve is the difference between a patient's visual ability and the visual ability needed to perform an activity.

  30. VA LV VFQ-48--Composite Score

    The VA LV VFQ-48 is a self-report instrument designed to measure difficulty visually impaired persons have performing daily activities. The acceptable range for the average item score is \<= 2.34 and \>=-2.22. Scores out of this range indicate something other than visual impairment is governing the patient's responses. The reading domain score is calculated by calculating the average score of reading items. The composite score approximates a person's visual ability. The score is calculated using Massof's algorithm using the inverse hyperbolic tangent equation. For the composite score, a lower score is better.

Outcome measures

PrimaryHumphrey Visual Field Perimetry

The area of the subject's visual field measured by 30-2 Humphrey visual field (HVF) perimetry. Both left and right sides will be tested. The deficit side includes is the hemianopic side. The intact side is the non-hemianopic side. During the HVF test, light is projected into a white bowl with a standardized background light intensity to form a circular stimulus, around 30 cm away from the patient's eye. The overall field mapping technique used is a form of static perimetry, where a stimulus appears in various areas of the field of vision. The patient indicates when they can see the stimulus and the perimetrist then records the point where the stimulus was seen. These data points are used to determine the patient's visual field.

SecondaryVA LV VFQ-48--Reading Domain Score

The VA LV VFQ-48 is a self-report instrument designed to measure difficulty visually impaired persons have performing daily activities. The reading domain score is calculated by calculating the average score of reading items. Scores range from 0 to 3.5 logits, with higher scores denoting better ability to perform activities. The Reading Domain Score is the average functional reserve of the items measuring the reading functional domain, excluding items which were rated Unscored (Difficult / don't do for Non-Visual Reasons).
