Retinoskopiaga

Retinoskopiaga is a diagnostic technique used in ophthalmology to measure a person's refractive error. It involves projecting a light beam into the eye and observing the movement of the light reflex on the retina. A trained examiner, often an optometrist or ophthalmologist, uses a retinoscope, a specialized instrument with a light source and a mirror or lens, to direct this light. By manipulating lenses in front of the patient's eye and observing how the reflex moves, the examiner can determine the eye's focusing power. The goal is to neutralize the reflex, meaning to stop its movement. When the reflex is neutralized, the lenses in place correspond to the patient's refractive error, which can be expressed in diopters. This process helps identify conditions like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Retinoskopiaga is a valuable tool for prescribing corrective lenses, such as glasses or contact lenses, and is often performed as part of a comprehensive eye examination, particularly for children or individuals who cannot accurately communicate their vision. It is a relatively quick and objective method for assessing refractive status.
