HESS CHART : Principles, Indications, and Procedure

Welcome to our educational video on Hess charting, a crucial investigation technique used in squint evaluation. In this detailed guide, we will delve deep into the world of Hess charting, exploring its principles, methodologies, and significance in diagnosing and treating strabismus (ocular misalignment).

What is Hess Charting?
Hess charting is a specialized diagnostic tool employed by ophthalmologists and optometrists to assess and analyze eye movements in patients with strabismus or eye misalignment. This investigative approach is rooted in the principles of haploscopy and foveal projection, herrings and sheringtons law allowing professionals to map out the precise positions of the eye in nine different gazes.

Understanding the Principles:

Haploscopic Principle: Haploscopy involves dividing the physical space into two by presenting two visual objects to the patient's eyes and ensuring that both objects are projected onto the fovea. This principle is critical in Hess charting, as it aids in evaluating how the eyes move and align relative to the central fixation point. By observing how the two visual objects are perceived and aligned on the fovea, clinicians can gain valuable insights into eye coordination and alignment.

Foveal Projection: Central to Hess charting is the principle of foveal projection, which focuses on the fixation point of the fovea centralis in each eye. By tracking how the eyes move relative to this central point, clinicians can pinpoint deviations and abnormalities in eye alignment.

How to Perform Hess Charting:
In this video, we will walk you through the step-by-step process of conducting Hess charting. You'll learn about the essential equipment required, including the Hess screen and specialized tools for ocular assessment. We'll also discuss patient positioning.

Why Is Hess Charting Important?
Hess charting plays a pivotal role in diagnosing and planning treatment for strabismus. By creating a visual representation of eye movement in different directions, healthcare professionals can identify the extent of ocular misalignment and develop tailored treatment strategies, which may include eye exercises, prisms, or even surgical intervention.
