OptoReflex: Eye Tests
Optokinetic, pupil & gaze
$0.99 · Designed for iPad. Not verified for macOS.
IMPORTANT — PLEASE READ
OptoReflex is a set of visual stimuli and observation tools for teaching and for supporting the examiner's own observation. It is not a medical device, it does not diagnose, and it must not be used to make medical decisions. Always consult a physician and use validated equipment for medical assessment.
OptoReflex turns your iPhone or iPad into a pocket kit of classic neuro-ophthalmology stimuli for clinicians, students and educators.
WHAT'S INCLUDED
• Optokinetic drum (OKN)
Full-screen moving stripes act as a digital optokinetic drum. Choose colors, speed, stripe width, pattern and direction, with a live preview. Speed can be shown in degrees per second for the viewing distance you set.
• Smooth pursuit and saccade targets
A target that glides (pursuit) or jumps between points (saccades) along horizontal, vertical or circular paths. Adjustable speed, amplitude, size and color.
• Nine gaze positions
A target that steps through the nine positions of gaze while you observe the eyes.
• Pupillary light reflex — observation
The rear camera works as a magnifier with macro focus, and the flashlight delivers timed stimulus sequences (direct, consensual, alternating light, light/dark) with countdown and voice cues. For teaching, an approximate pupil diameter is shown together with the outline the app detected. It is an estimate based on an assumed iris diameter, not a clinical measurement.
• Pupil gauge
Circles from 1 to 9 mm at actual size on the screen, like the gauge printed on clinical penlights, for visual comparison by the examiner. Size can be calibrated with a standard bank card.
• Amsler grid
A standard grid with a central fixation dot, normal and inverted modes, drawing of the areas the person describes, and side-by-side comparison by eye.
RECORDING AND PRIVACY
Sessions can be recorded with the device camera. Videos stay in a private area on your device, with optional name or ID and date, and can be protected with Face ID. Nothing is uploaded.
LANGUAGES
English, Spanish, Portuguese, French, German, Italian, Chinese, Japanese, Arabic and Russian, with an in-app selector.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This version removes every automatic camera analysis: eye tracking, pupil response metrics, visual screening, photo analyses and trend charts. The app now focuses on visual stimuli, observation and teaching.
The pupil screen keeps an approximate diameter with the detected outline, clearly labeled as an educational estimate that must not be used for medical decisions.
New: on-screen pupil gauge with 1–9 mm circles at actual size.
Records saved by earlier versions remain available for viewing and export.
