Objective Visual Field Maps are generated following SVOP tests, even if the patient is a child or a patient who is difficult to test with standard visual field analysers.
Use of integrated Eye Tracking technology removes the need for the patient to fixate or to remain still during the test. Instead, the patient’s eyes instinctively follow a series of images on screen. Interpretive algorithms compensate for movement to output a standard Visual Field Map.
Instructions for the patient are minimal. Children and other patients who cannot understand instructions are simply positioned facing the screen so their eyes can instinctively follow the images. Young children can sit on their parents lap during the test and simultaneously receive parental encouragement to maintain their continued engagement throughout the test.
Paediatric patients as young as three have been routinely tested, the short length of the test being advantageous in holding the attention of the child for the duration of the test.
The youngest child to be tested was a healthy child of 8 months old, who successfully completed a visual field test using an SVOP instrument under experimental conditions.
