Retinoscopy (Plus Cylinder)

This course is in power point format and includes multiple simulations to aid you in the understanding of how to perform retinoscopy. It is intended for beginning and intermediate levels.

After completing this section the student should be able to do the following:

• Identify the parts on the phoropter
• Define Refraction and retinoscopy
• Describe how to properly position a patient behind the phoropter
• State the purpose of retinoscopy
• List the steps for checking near vision through the phoropter
• Identify the Prince Rule for a phoropter
• State which way the sphere dial should be moved to change the sphere power in the plus direction
• State which way the sphere dial should be moved to change the sphere power in the minus direction
• Identify the cylinder axis dial
• Identify the cylinder power dial
• Describe how the retinoscope is used in retinoscopy
• State the significance of the sleeve on the retinoscope
• List the main steps to getting a patient ready to retinoscope
• Identify and define WITH movement
• Describe why WITH movement happens
• Identify and define AGAINST movement
• Describe why AGAINST movement happens
• Identify and define the NEUTRAL reflex
• Describe why the NEUTRAL reflex happens
• State what steps to take to neutralize WITH movement
• State what steps to take to neutralize AGAINST movement
• Identify a spherical eye in retinoscopy simulation
• Identify an astigmatic eye in retinoscopy simulation
• Locate the axis of astigmatism in retinoscopy simulation
• Neutralize an eye refractive error in retinoscopy simulation
• Define working distance
• State how to take away your working distance
• Identify which meridian to neutralize first- WITH or AGAINST
• Identify the final retinoscope RX looking at the phoropter

This course should take approximately 1.5 hour to complete.
