OKKO Health

What OKKO Health does

OKKO Health (legally Okulo Limited) is a Bristol-based digital health company founded in 2018 that develops smartphone-based vision monitoring software for patients with age-related macular degeneration (AMD) and other retinal conditions. The core product is a patient-facing mobile application that uses gamified tests to measure visual acuity, contrast sensitivity, and visual distortion — built on logMAR methodology — supplemented by front-facing camera capture of viewing distance and head position to standardize test conditions. Test data is transmitted to a web-based Clinician Dashboard where eye care professionals review longitudinal trends and receive alerts when patient readings deviate from baseline, enabling earlier intervention than standard in-clinic appointment schedules typically allow.

The platform is regulated as a Class I medical device — FDA-registered and 510(k)-exempt in the U.S., CE-marked under both UK MDD and EU MDR in Europe — and is independently audited to ISO 27001, with HIPAA and GDPR compliance for data handling. OKKO is layering anomaly detection and predictive analytics on top of its longitudinal dataset, with stated intent to identify disease activity at the earliest possible opportunity. The company is incorporated as Okulo Limited in England and Wales and operates from 17-19 Berkeley Square, Bristol.

Revenue is generated through a B2B SaaS model sold to ophthalmologists, optometrists, and eye care practices, who in turn bill U.S. payers under Remote Physiologic Monitoring CPT codes (99453, 99454, 99457, 99458), with additional Chronic Care Management and Principal Care Management pathways. The company has expanded beyond AMD patients to serve clinical trial participants and pharmaceutical/medical device companies that require home-based vision endpoints. Headcount is reported in the 11–50 band, with leadership including CEO and Founder Dr Stephanie Campbell, CFO Matt Halstead, and a board chaired by Dr Claire Novorol. The company has raised a £2m pre-seed round (October 2022) led by DvH Ventures, alongside multiple Innovate UK grants and earlier angel rounds since 2018, with a strategic investment and partnership from Topcon Healthcare announced in October 2025.

Core offering

OKKO Health develops and sells a smartphone-based home vision monitoring platform consisting of a patient-facing mobile app and a Clinician Dashboard. The app uses gamified visual function tests (visual acuity, contrast sensitivity, visual distortion) to enable AMD patients to monitor their vision between clinic appointments, while the dashboard gives eye care professionals longitudinal data, alerts on deviations from baseline, and tools to bill under Remote Physiologic Monitoring CPT codes.

Product overview

OKKO Health offers a dual-component product system consisting of a patient-facing mobile application and a Clinician Dashboard. The OKKO Health mobile app enables patients to monitor their vision at home between clinic appointments through smartphone-based vision tests. Vision data collected from the app is transmitted to the Clinician Dashboard, which gives eye care professionals access to longitudinal patient data and automated alerts when significant deviations from baseline are detected. The platform supports Remote Physiologic Monitoring (RPM) billing and is designed for adults with intermediate AMD or treated wet AMD.
