## What is Exophthalmometer?

REQUIRES LIDAR CAMERA - CHECK YOUR IPHONE BEFORE PURCHASING TO CONFIRM HAS LIDAR

Graves and Thyroid Eye Disease offers individuals living with Thyroid Eye Disease (TED) a unique way to document and visualize their eye measurements for personal educational purposes. Using the advanced LiDAR sensor and camera on your compatible iPhone or iPad, this app helps you create 3D facial models to better understand and track estimated changes in ocular protrusion (exophthalmos) over time.

How It Works:

Scanning (Requires Assistance): Due to the nature of facial scanning, you will need another person to help capture the 3D data. The assistant will use your device to slowly move around your face, capturing images and depth information according to the in-app guidance.

3D Model Creation: The app processes the captured data to generate a textured 3D model (.usdz format) of your face.

Calibration: Before measuring, the app needs calibration using your pupillary distance (PD). You can obtain this using the app's TrueDepth camera feature (requires Face ID capable device), an on-screen ruler tool, or by manually entering a known value.

Virtual Measurement: Load your saved 3D models within the app. Carefully tap on specific anatomical landmarks (corneal apices and lateral orbital rims) as guided. The app then calculates estimated protrusion values based on these landmarks and the PD calibration.

Key Features:

Assisted 3D Facial Scanning: Capture detailed scans with the help of another person.

Personal 3D Model Library: Generate and save .usdz models directly on your device.

PD Calibration Options: Use TrueDepth, ruler, or manual entry for measurement scaling.

Estimated Protrusion Measurement: Mark landmarks on your 3D models to get approximate exophthalmometry values.

Proptosis Difference Calculation: See the estimated difference in protrusion between your eyes.

Measurement History & Chart: Log your measurements and visualize trends over time for educational insight.

Intended Audience & Purpose:

This app is designed for individuals diagnosed with Graves' Disease or Thyroid Eye Disease who wish to document their personal journey and visualize estimated eye measurements for educational purposes only. It can serve as a personal visual diary to observe potential changes alongside regular professional medical care.

THIS APPLICATION IS FOR EDUCATIONAL AND PERSONAL DOCUMENTATION PURPOSES ONLY. IT IS NOT A MEDICAL DEVICE AND IS NOT A SUBSTITUTE FOR PROFESSIONAL MEDICAL EVALUATION OR CARE.

Not for Diagnosis or Treatment: DO NOT use this app to self-diagnose, make treatment decisions, or replace visits to your ophthalmologist or endocrinologist.

Measurements are ESTIMATES Only: The measurements provided are approximations based on consumer-grade mobile sensors and user interaction.

Significant User Error Potential: Accuracy depends heavily on your ability to correctly identify and precisely tap the anatomical landmarks on the 3D model. Incorrect landmark placement will lead to inaccurate measurements.

Not a Replacement for Clinical Tools: This app's results are NOT equivalent to measurements taken with a calibrated clinical instrument like a Hertel exophthalmometer performed by a trained healthcare professional.

Consult Your Doctor: Always discuss any concerns about your eye health or measurements with your qualified healthcare providers. Rely solely on their professional assessments for any medical decisions.

NO DATA TRANSMISSION: The application does not send ANY scan data, 3D models, measurements, or any other personal information to the developer or any third party. There is no cloud component or external server communication involving your measurement data.

LOCAL STORAGE ONLY: All information generated by the app (scans, models, history) is stored exclusively and securely on your own iPhone or iPad within the app's designated folder in the Files app ("On My iPhone/iPad" -> "Graves Disease Scanner").
