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.
Components Tab

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, Early, 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

The stage does not diagnose disease or replace clinical judgment. It supports more consistent conversations with patients, colleagues, referral partners, and specialists.

VR-Powered Visual Diagnostics. AI-Powered Clinical Confidence.
