The OCULUS Smartfield is a compact visual field device purposefully optimized for monitoring functional impairment in glaucoma. Based on an ultra-high-luminance LCD screen it performs standard automated perimetry of the central visual field and beyond. Despite its small size, the Smartfield perimeter offers a comprehensive clinical solution in visual field testing for any glaucoma practice.
Ergonomic Design
The OCULUS Smartfield stands out with a very small footprint, which is smaller still than that of the Easyfield®. Its closed design and light-protected viewer permit examinations in rooms with normal lighting conditions. Its low weight and the practical carrying handle make the Smartfield perimeter convenient for portable use. The height-adjustable double chin rest and measuring head allow for better positioning of the patient and improved comfort. The absence of moving parts guarantees a long product lifetime.
Easy Operation
The Smartfield perimeter is designed for operation via an external computer (notebook or PC) connected to the common office data network. This ensures network availability of examination data. The translucent lateral eye shields render the use of an eye patch during the examination unnecessary, thus saving valuable time in preparation for the test.
Increased Diagnostic Reliability
Powerful test strategies such as SPARK and other assessment tools contribute to the great diagnostic utility of the Smartfield perimeter. The enhanced Glaucoma Staging System (GSS 2) of Dr. Brusini and the Glaucoma Staging Program (GSP) offer extended support in single field analysis. Structure-function relationships are predicted by the new PATH evaluation module. The Threshold Noiseless Trend (TNT) module performs efficient progression analysis. Examination quality is ensured by a patented fixation control algorithm, a high resolution video camera for eye monitoring and the various built-in catch trials.
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.
