retinoscopy การใช้

• Static retinoscopy is performed when the patient has relaxed accommodative status.
• To perform a retinoscopy, the doctor projects a streak of light into a pupil.
• Dynamic retinoscopy is performed when the patient has active accommodation from viewing a near target.
• Static retinoscopy is a type of retinoscopy used in determining a patient's refractive error.
• Static retinoscopy is a type of retinoscopy used in determining a patient's refractive error.
• An automated refractor is an instrument that is sometimes used in place of retinoscopy to objectively estimate a person's refractive error.
• The examinee must demonstrate the ability to complete seven tasks commonly performed on the job, such as retinoscopy, that are simulated on a computer.
• The parameters specified on spectacle prescriptions vary but typically include the power to which each lens should be made in order to correct blurred computer automated refractor, or through the technique of retinoscopy.
• An autorefractor or retinoscopy may provide an objective estimate of the eye's refractive error and the use of Jackson cross cylinders in a phoropter may be used to subjectively refine those measurements.
• Retinoscopy is particularly useful in prescribing corrective lenses for patients who are unable to undergo a subjective refraction that requires a judgement and response from the patient ( such as children or those with severe intellectual disabilities or communication problems ).
