HESS CHART / DIPLOPIA CHART / HESS SCREEN / Eye Movement Test / Diplopia Grid Chart / Hess Lancaster Test / Orthoptics Hess Chart / Strabismus Test
Hess Chart (position) The basic principle of Hess chart is foveal projection therefore the higher field belongs to the higher eye. This is opposite of diplopia charting where the higher image is of the lower eye. Position of the central dot indicates whether the deviation is in primary position or not. Hess Screen is used to test the function and co-ordination of the extra-ocular muscles to aid the diagnosis of ocular motility disorders. The full set comprises a 81 cm x 81 cm x 2.5cm size electronic grey screen with 25 red lights, a pack of corresponding recording charts, a green laser pointer with AAA batteries, red/ green dissociative goggles and a power unit. The fixation lights are positioned so that they are at 15-degree intervals when viewed at the correct testing distance of 50 cm from the screen. The red lights are illuminated one at a time, as selected by an operator holding the control unit. The screen markings also indicate 5 degree steps between the red lights. The fixation points are tangentially compensated in the way normal for any flat screen. The patient should be seated so their eyes are direct ly in line with the central fixation point on the chart and instructed to move their eyes to view each red light as it is lit by the operator, then to indicate with the green laser pointer where that light appears on the chart. A chin rest is recommended to prevent head movement during testing (please note this will need to be purchased separately). The Hess Screen is designed to be wall mounted, usually in a room which can be darkened to a level suitable for both operator and subject. The screen unit is provided with two hanging plates. The power unit has a lead length of 1.5 meters and the control box lead is 2 - 3 meters from the chart.
