Go behind the science of Severity Index
Join Dr. Siamak Yousefi, PhD, FARVO, and Dr. Rehan Ahmed, MD, as they discuss the clinical challenges of visual field severity staging, the machine learning methodology behind Severity Index, and what AI means for the future of glaucoma care.
How It Works
From Complex Visual Field Data to Objective Severity Staging
Severity Index brings AI-powered visual field severity staging directly into Carrot’s 24-2 report—helping clinicians understand, communicate, and review functional vision loss with greater consistency and confidence.

Step 1
Start with the same 24-2 test you already know
Patients complete the 24-2 visual field the same way they do today. No additional testing, technician steps, or separate software required.
Step 2
Open your patient's 24-2 report
Severity Index appears directly inside Carrot’s updated report experience, alongside the visual field data clinicians already review.
Step 3
Get an objective severity stage instantly
Each reliable 24-2 visual field is automatically staged as Normal, Mild, Moderate, or Advanced using an AI-powered model developed from 50,000 reliable visual fields.
Step 4
Use AI as a second set of eyes
Severity Index helps reduce the cognitive load of visual field review by giving clinicians a standardized reference point to assess, communicate, and contextualize severity.
Step 5
Create a clearer path for conversations
Severity Index does not diagnose disease or replace clinical judgment. It supports more consistent conversations with patients, colleagues, referral partners, and specialists.
Why It Matters
Turn Complex Visual Field Data into Clear Clinical Insight
Severity Index transforms complex visual field data into a clear, standardized severity stage—giving clinicians an objective reference point directly within the report.
A New Way to Understand Visual Field Severity
For decades, visual field severity staging has relied on clinical experience and subjective interpretation.
Severity Index introduces a new approach.
Built from machine learning analysis of 50,000 reliable visual fields, Severity Index automatically stages visual fields as Normal, Mild, Moderate, or Advanced—providing clinicians with an objective second set of eyes during report review.
Designed to support clinical judgment, not replace it.

How Akler Eye Center Modernized Visual Field Testing Without Sacrificing Clinical Confidence
When Akler Eye Center set out to improve the patient experience, they didn't expect to transform their entire approach to visual field testing. See why they switched to Carrot—and why they have no interest in going back.

The New Gold Standard in Automated Perimetry
Carrot set the standard for VR visual fields when we introduced the first virtual visual field system in 2018. Today, our clinically validated testing is benchmarked against SITA, delivering accurate, repeatable results that support confident diagnosis and a seamless transition to modern visual diagnostics.
"Now that we have [Carrot], we can put patients in exam rooms and conduct their visual field testing, keeping the diagnostic room open for other tests and patients."
