What it measures

Penlight Out. Precision In.

Quantitative pupillometry replaces subjective penlight observation with objective, reproducible data. Carrot’s VR-enclosed environment delivers controlled, consistent light stimuli while infrared sensors capture pupillary response - across light and dark irises alike.

Pupillometer Features

Pupil Diameter Measurements

Sub-millimeter resolution at baseline, at peak constriction, and across the full response curve. The foundation of every other measurement.
pupillometer pupil diameter

Pupillometer Features

Response Velocity

Constriction and dilation speed, captured continuously. Direct indicators of afferent pathway integrity and autonomic balance.
pupillometer response velocity

Pupillometer Features

Response Timing

Constriction latency and recovery time, measured to the millisecond - a resolution penlight assessment cannot approach.

Pupillometer Features

RAPD Magnitude

Quantified asymmetry between eyes, automatically calculated across the test cycle. The signal that surfaces optic nerve disease before symptoms appear.

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.

FAQs

Questions about Carrot?

As a company that’s creating and innovating the category of virtual visual field testing, you likely have questions about what we offer, how it scales, and how we support our network of providers and practice administrators. Please browse our FAQs or contact our team.

Yes. Carrot supports one-click export of visual field testing and perimetry results as PDF, CSV, and structured data formats compatible with most EHR systems. With DICOM 360 Sync (available with our Pro subscription), finalized reports are automatically pushed to your EMR/EHR and PACS, eliminating manual uploads.

Pupillometry testing with Carrot takes approximately 15–20 seconds for both eyes. Simultaneous infrared imaging captures accurate pupil response data quickly, minimizing patient disruption and chair time.

CPT 95919 is the dedicated code for quantitative pupillometry with physician or qualified health care professional interpretation and report, unilateral or bilateral. Reimbursement varies by payer and geographic region. For current rates and bundling rules specific to your practice, consult your billing team or the most recent Medicare Physician Fee Schedule.

Both rely on the same fundamental technology — infrared imaging of pupil response to controlled light stimuli, captured automatically to quantify pupil diameter, latency, and velocity. The key difference is form factor and workflow: Carrot delivers pupillometry through the same portable VR headset that runs your visual field, color vision, and ocular motility exams — eliminating the need for a dedicated device, room, or workflow. The device also takes care of all the instructions and corrections so the tech can spend their time more efficiently. 

Yes. Pupillometry runs on the same Carrot headset as 24-2, 24-2C, 10-2, color vision, ocular motility, and other exams on the platform. Technicians can launch multiple tests in a single patient session — one device, one setup, one consolidated report — without moving the patient between rooms or devices.

Pupillometry is included in Pro subscriptions. See our pricing page or speak with your account manager for full subscription details.
