Question 1

What is RetGuard?

Accepted Answer

RetGuard is an AI-powered retinal screening system designed for point-of-care deployment. It enables healthcare providers to screen for multiple retinal diseases in under 30 seconds — without requiring cloud connectivity or specialized ophthalmology training. Everything runs locally on a compact device right in the clinic.

Question 2

What conditions does RetGuard screen for?

Accepted Answer

RetGuard screens for five major retinal conditions: Diabetic Retinopathy (DR), Glaucoma, Hypertensive Retinopathy, Age-Related Macular Degeneration (AMD), and Diabetic Macular Edema (DME). Each condition is evaluated by a dedicated screening algorithm optimized for that specific pathology.

Question 3

How accurate is RetGuard?

Accepted Answer

RetGuard achieves clinical-grade accuracy across all five screening areas. Each screening algorithm is validated against expert ophthalmologist annotations and provides reliable confidence scores. This means the system not only detects conditions accurately but also reliably communicates its certainty level — critical for clinical decision-making.

Question 4

Does RetGuard replace the need for an ophthalmologist?

Accepted Answer

No. RetGuard is a clinical decision support tool, not a diagnostic device. It is designed to assist trained healthcare professionals by providing rapid, AI-driven screening results. Positive findings should always be confirmed by a qualified ophthalmologist. RetGuard helps identify patients who need specialist referral, improving early detection in primary care settings.

Question 5

How is RetGuard different from other screening solutions?

Accepted Answer

RetGuard distinguishes itself through its privacy-first design. Unlike cloud-based solutions, all processing runs locally on the device, meaning patient data never leaves the clinic. It also provides visual evidence showing regions of clinical interest in each retinal image, offering clinicians transparency and interpretability that most screening systems lack.

Question 6

What hardware is required?

Accepted Answer

RetGuard ships as a self-contained screening device, which is included with the system. You also need a compatible fundus camera or OCT device for image acquisition. The device provides sufficient performance to run all five screening algorithms concurrently while maintaining the sub-30-second screening time.

Question 7

Does RetGuard need internet connectivity?

Accepted Answer

No. RetGuard is designed to run entirely on-device, meaning all processing happens locally. No internet connection is required for screening. This ensures patient data never leaves the clinical environment and allows the system to operate in remote or connectivity-limited settings. An optional internet connection can be used for software updates and remote support.

Question 8

How is patient data protected?

Accepted Answer

Patient data protection is fundamental to RetGuard's design. All image processing occurs on the local device — no patient images or data are transmitted to external servers or the cloud. The system does not store patient images after screening is complete unless explicitly configured to do so. This on-device approach provides inherent privacy advantages and supports HIPAA and GDPR compliance requirements.

Question 9

What technology does RetGuard use?

Accepted Answer

RetGuard uses specialized screening algorithms, each optimized for a specific retinal condition: Diabetic Retinopathy, Glaucoma, Hypertensive Retinopathy, AMD, and DME. All algorithms provide reliable confidence scores and visual evidence showing regions of clinical interest for clinical interpretability. The system is optimized for real-time performance, delivering results in seconds.

Question 10

What image modalities are supported?

Accepted Answer

RetGuard supports both fundus photography and Optical Coherence Tomography (OCT) imaging. The system accepts standard image formats from most commercially available fundus cameras and OCT devices, making it compatible with equipment already present in many clinical settings.

Question 11

How are screening results delivered?

Accepted Answer

Results are displayed in real time on the RetGuard interface within seconds of image capture. Each screening report includes the classification result, a reliable confidence score, and visual evidence showing the retinal regions of clinical interest that informed the screening outcome. Reports can be exported as PDFs for patient records.
