Yes. AAO recommendations for POAG Suspects can be found here and POAG here. AOA recommendations can be found here.
In most, if not all states in the USA, yes. Many other countries also require or recommend pupillary testing.
Less than 1 minute.
Yes. Results are presented as the ‘RAPDx score’, which is an analog of the swinging flashlight method APD. With the flashlight this is quantified using neutral density filters. Note the RAPDx score is an order of magnitude more granular than ND quantified asymmetry, E.G. 0.37 (RAPDx score) vs 0.3 (NDF).
It does not. It means the pupillary reflex is symmetric, and could mean that both eyes or normal of both eyes are affected equally. It does however provide objective documentation that the APD was not missed.
Less than 1 minute.
Maybe. It meets the criteria however please consult with your tax professional.
It is quick and easy to sanitize using at 70% isopropyl alcohol and no additional cleaning is required specifically for COVID-19. There is an additional benefit in terms of greater distance from the patient compare to the singing flashlight test.
No. Pupillary light reflex testing is an included component of a comprehensive eye exam and is not billed separately.
