iTorsion

Functionality & Mechanism

This medical diagnostic utility, iTorsion, is designed to assist physicians in measuring ocular torsion. The application utilizes a smartphone's display and standard red/green glasses to present separate lines to each of the patient's eyes. The patient is then prompted to manipulate the lines on the screen until they appear parallel to each other and to the ground. Based on this user input, the app calculates and reports the precise degree of extorsion and intorsion for each eye.

Development & Context

• Traditional methods for diagnosing ocular torsion often lack precision and require specialized equipment like a Double Maddox Rod.
• The app was developed to offer a simpler, low-cost diagnostic method using only a smartphone and red/green glasses.
• The news coverage notes that the application is available for iPhone and iPad on the Apple App Store.
• Its design aims to provide better precision than the traditional diagnostic approaches it is intended to supplement.

Intended Use & Scope

iTorsion is designed exclusively for use by physicians and ophthalmologists as a tool to support ocular torsion diagnosis. It is explicitly not intended for patient self-diagnosis. The scope is limited to measuring the degree of ocular extorsion and intorsion, and its use requires a smartphone and standard red-green glasses.
