Using an Automated Hirschberg Test App to Evaluate Ocular Alignment

Overview

This article presents a protocol for using a smartphone app to perform the Hirschberg test, which measures ocular misalignment (strabismus) under different fixation conditions. The app simplifies the measurement process, making it accessible for both research and clinical use.

Key Study Components

Area of Science

• Ophthalmology
• Clinical Measurement
• Mobile Health Technology

Background

• Strabismus measurement typically requires extensive training.
