Retinoscopy

Retinoscopy is a technique used in ophthalmology to determine the refractive error of the eye and the need for glasses. It is a simple, non-invasive method that can be used on all patient populations.

Procedure[edit | edit source]

The procedure of retinoscopy involves the use of a handheld device called a retinoscope, which emits a beam of light. The light is shone into the patient's eye and the reflection, or reflex, is observed. The direction, quality and movement of this reflex can provide valuable information about the patient's refractive error.

Types of Retinoscopy[edit | edit source]

There are two types of retinoscopy: static and dynamic.

Static retinoscopy is performed when the patient's eye is at rest and the focus is on the retina. This method is used to determine the patient's refractive error without any accommodation (focusing effort).

Dynamic retinoscopy is performed while the patient is focusing on a near object. This method is used to assess the patient's accommodative effort and to determine if they may benefit from reading glasses.

Clinical Uses[edit | edit source]

Retinoscopy is used in a variety of clinical settings, including:

Determining the need for glasses or contact lenses
Diagnosing refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia
Assessing the effectiveness of current glasses or contact lenses
Monitoring the progression of refractive errors
Evaluating the need for refractive surgery
