Hess Laser Screen Test and Accessories

The Hess Laser Screen Test is 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 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 cyclodeviation resulting from the ocular muscle imbalance.
