Hi Connie. Is there a recommended size of the accommodative target for this test that is given to patient? (e.g. 2 line above the best corrected VA at distance or N10 at near, something like this?)

[@dormouzeaoi1364]

Hi Connie. One question to ask. When we do PFR, do we stop and record down the break point when the patient first notice double? Or do we keep going if the patient is able to fuse the image back to one after first getting double?

I have encountered an adult patient who is orthophoria. But when I measured her PFR at 6m, she could fuse a distance accommodative target up to 35 prism diopter BO with effort. Is that abnormal?

If the patient can comfortably regain single vision, I would continue to the next prism.
