Question 2: What is your assessment of the visual fields?

Answer

This is a HVF 24-2 visual field for the right and left eye. There is a superior hemi-field defect in the right eye. There is excessive gaze movement. The left eye visual field is unremarkable aside from some increased eye movement towards the end of the test.
