Mastering Your Static Retinoscopy Technique: A Student Guide
In the modern world, where automated eye exams are creeping in, there is one skill that remains the ultimate “lie detector” for an optometrist: static retinoscopy. Also known as “skiascopy,” this is the art of objectively measuring a patient’s refractive error using nothing but light and lenses. While auto-refractors are quick, they can be fooled…

Look Sharp: The Extraocular Muscles Behind Eye Movement
The extraocular muscles are the powerhouse of eye movement. They work behind the scenes, shifting our gaze, tracking objects, and keeping vision stable as we move through the world. Six muscles1 control these precise movements, each playing a vital role in positioning the eyes. Whether looking up, down, side to side, or adjusting for fine…

Goldmann Applanation Tonometry: You’ve GAT This!
Goldmann Applanation Tonometry (also known as GAT) is the most trusted method for measuring intraocular pressure1 (IOP), crucial for detecting and managing glaucoma, amongst other reasons for requiring an IOP measurement. This technique involves flattening a small part of the cornea1,2 to estimate the eye’s internal pressure. Using the Imbert-Fick principle2, Goldmann applanation tonometry delivers…

Duochrome Test: A Simple Trick to Aid Your Refraction
The duochrome test is a simple yet powerful tool in subjective refraction1. It helps fine-tune the spherical endpoint by using longitudinal chromatic aberration1,2. Chromatic aberration is a property within optics where different wavelengths of light focus at slightly different points2. The test presents black letters or circles against a red-green split background2 (Figure 1). This…

Van Herick Technique: An Angle for Beginners
The Van Herick technique is a straightforward and effective way to assess the anterior chamber angle1,2. By using a slit lamp to observe the gap between the corneal endothelium and the iris surface, this method allows practitioners to quickly determine if further investigation is needed without discomfort to the patient. Moreover, it offers great interobserver…

Slit Lamp Filters: Lighting the Way to Better Eye Exams
Slit lamp filters play a crucial role in modern eye examinations. These adjustments to the slit lamp illumination can increase your ability to assess the eye effectively. Each filter has its own purpose, helping practitioners assess, diagnose, and manage various eye conditions with precision. From improving contrast to highlighting fluorescein staining, they add incredible value…

The Near Point of Convergence: Bringing the Eyes Together
The near point of convergence (NPC) is an important measurement in optometry, often overlooked by those both inside and outside the field. It’s a measure of how well the eyes can converge, or turn inward, to maintain single vision when looking at a close object. This simple yet effective test can diagnose a range of…
