Hess Laser Test – Complete Kit
Product Description
P/N 6710R Complete Hess Laser Test kit includes Red Green Lasers, Roll-Up Screen, Heavy Duty Chin Rest, Adult and Pediatric Red/Green Glasses, Instructions and Score Sheets.
Hess Lasers include one red and one green lasers and project a single dot of each color. Hess Lasers can be used with Lancaster Screen and score sheet or with our parabolic Hess screens. Hess Laser kit includes red and green Lasers plus specially adapted adult red/green glasses to insure good cancellation. Includes pack of 50 Score Sheets and instructions.
The main difference between the Hess and Lancaster tests is that the Lancaster projects a line whereas the Hess pointers project a simple dot. Lancaster line generators permit determination of the orientation of the patient’s vision. Orientation is important in understanding any cyclo-deviation resulting from the ocular muscle imbalance.
The Hess Test may be more useful in understanding full visual field and any Aniseikonic affects. Further, the Hess Test may be more simple for children to understand thus yielding more reliable results in pediatric situations compared to Lancaster Test.
The Roll-up screen is approximately 4x4x63 inches (15 x 15 cm x1.6 Meter) and is expensive to ship outsdie of North America. We recommend the fold-up Hess Screen (part number 5774) for overseas shipping.
