Henson 9000 Review: The Most Reliable Field Screener for Optometry?

Revolutionising Your Practice: Why the Henson 9000 is the Smart Choice for Visual Field Screening

In a busy optometry practice, time is your most valuable currency—but clinical accuracy is your reputation. For years, the industry has sought the perfect balance between "quick screening" and "reliable diagnosis." Enter the Henson 9000, a compact powerhouse that bridges that gap without breaking your workflow.

Speed That Doesn’t Sacrifice Detail

Patient fatigue is the enemy of reliable data. The Henson 9000 tackles this head-on with its Smart Supra test. Unlike traditional screeners, it can complete a standard screening in under a minute per eye.
But here is the clever part: if a patient misses a point, the system doesn’t just mark it as a fail. It automatically extends the test pattern—from 26 points up to 86—incorporating critical points from both 24-2 and 10-2 patterns. This ensures you don't miss those subtle central defects that often slip through standard 24-2 screenings.

The Intelligence of ZATA

For long-term management, the Henson 9000 uses the Zippy Adaptive Threshold Algorithm (ZATA). This isn't just a catchy name; it’s a Bayesian-based method similar to the industry-standard SITA but with a unique twist.
ZATA is uniquely capable of using a patient's prior test data to start the next session. Instead of starting from scratch every time, the machine "remembers" the patient's thresholds, focusing its efforts where they matter most. Clinical studies have shown that for early glaucoma, this can make tests roughly 1.06 minutes faster per eye than other gold-standard perimeters.

Why Optometrists Love It

Space-Saving Design: Its compact, ergonomic footprint is a lifesaver for smaller consulting rooms.
Low Maintenance: Built with robust, solid-state electronics and degradation-free light sources, it’s designed for years of reliable service with minimal upkeep.
Easy Integration: It runs on a Windows platform, making it easy to integrate with your existing Practice Management Software (PMS).
Staff Friendly: With an intuitive touch-screen interface and context-sensitive help, training your team is a breeze.

The Bottom Line

The Henson 9000 isn't just a piece of equipment; it’s a workflow upgrade. It allows you to screen more patients, detect early-stage glaucoma with higher sensitivity, and keep your clinic running on schedule.
