Detailed Information
Examination Programs
The Smartfield is equipped with a set of predefined programs for the most frequently needed examination routines of the central visual field or the macular area. A default program for the periphery is also included. The program list can be easily extended according to specific requirements by combining the available test patterns and test strategies.
OCULUS Test Strategies
The Smartfield features the innovative SPARK test strategy for faster and more stable threshold measurements in glaucoma patients. Rounding off the testing capabilities of the Smartfield is the complete set of traditional OCULUS test methods, including threshold and suprathreshold strategies. The classical 4-2 dB staircase strategy (Threshold) uses two reversals in the patient’s answer to deliver a threshold value in each tested point. The OCULUS Fast Threshold strategy is a clever improvement over the classical procedure which reduces examination time by using variable steps and taking advantage of already measured locations. Suprathreshold strategies like the 2-zone or 3-zone strategy offer a quick overview of the visual field.
OCULUS Test Patterns
The grid corresponding to the SPARK examination strategy (30×24) is the preferred pattern in the Smartfield. However, other commonly used patterns such as 24-2 or 10-2 are readily available. Custom patterns for the central visual field can be easily created. The modular structure of the test programs allows for all patterns to be examined using any available standard strategy.
Results Printout
Measurement results of the Smartfield perimeter are commonly summarized in a standard printout. For suprathreshold tests a qualitative overview is printed, whereas for threshold examinations all clinically relevant data are shown in various representations. Besides the standard printout the Smartfield software features various assessment displays.
