## What is OptoReflex?

OptoReflex turns your iPhone or iPad into a quick, pocket toolkit for screening eye movements and reflexes at the bedside. It brings together classic neuro-ophthalmologic tests in one clean, fast app for clinicians, students and educators.

TESTS INCLUDED

• Optokinetic Reflex (OKN)
Full-screen moving stripes act as a digital optokinetic drum to elicit optokinetic nystagmus. Choose stripe colors (black/white by default), speed, thickness and direction, and see a live preview before you start. Turn the device to landscape and observe the patient's eyes.

• Smooth Pursuit & Saccades
A target that glides smoothly to test pursuit, or jumps between points to test saccades. Adjustable axis (horizontal, vertical, circular), speed, amplitude, target size and color.

• Amsler Grid
A standard grid with a central fixation dot to screen the macula for scotomas and metamorphopsia. Normal and inverted modes, full-screen display and step-by-step instructions.

• Pupillary Reflex with live pupillometry
Uses the rear camera with macro focus as a magnifier. It estimates pupil diameter in real time, tracks the minimum and maximum, and plots the response while a light stimulus ramps from dim to maximum to elicit constriction. Align the iris to the on-screen guide and watch the pupil outline track the response.

RECORDING
Any test can be recorded. Videos are stored locally on your device with the patient name and date — and, for the pupil test, the live pupil measurements — shown along the bottom of the video. Review, share or export your recordings at any time.

MANY LANGUAGES
Includes English, Spanish, Portuguese, French, German, Italian, Chinese, Japanese, Arabic and Russian, with an in-app language selector.

IMPORTANT — PLEASE READ
OptoReflex is a support tool for clinical examination and teaching. It is not a medical or diagnostic device and does not replace validated equipment, specialist assessment or clinical judgment. All measurements, including pupil diameter, are screening estimates that depend on lighting, camera focus and framing, and should be interpreted by a qualified professional.


## Version history (last 5 releases)

### 2.1.6 — 2026-09-24

General improvements and stability fixes.

### 2.1.5 — 2026-09-07

Improves live pupillometry stability and measurement reliability, with clearer separation between pupil and iris contours and stricter rejection of unreliable frames. Improves the recording start/stop flow so recording status reflects the actual video capture state.

### 2.1.4 — 2026-08-27

Updated App Store screenshots to better showcase live pupillometry and pupil tracking.

### 2.1.3 — 2026-08-24

Adjustments to pupillometry accuracy

### 2.1.2 — 2026-08-07

More accurate, reliable pupillometry: a new pupil detector that adapts to iris color, ignores the flashlight reflection, and measures the contour with far greater stability. The on-screen outline now tracks the pupil faithfully. Quality and performance improvements.
