  1. I'm surprised to see anything to do with eyes on the PANCE, I thought PAs weren't qualified to work for that specialty. Seeing as how I'm pre-PA and have been working with an ophthalmologist, do you happen to know if you ever see PAs working in that specialty?

    1. PAs are expected to do ophthalmic exams in any setting if any eye problems arise and know when there is an abnormality to refer. They can treat for simple things, like conjunctivitis, but like general physicians, they must know their limitations and know when they should refer to ophthalmologists. There aren't many PAs working in the ophthalmology field, but they are out there.

    2. ^^^ The person above is exactly correct. We aren't expected to know everything as PAs. Just like other family physicians we have to know our limits and know when to refer, but we should have a basic understanding to know and recognize the signs/symptoms of emergencies.

  2. Hey Paul, the info in your website is wonderful!!!
    One quick question need your advise..

    I read your previous article saying.. you do recommend the book of "The Color Atlas of Family Medicine" for family rotation.. now it has app (2013) about 94 bucks.. but the same company makes another app for another book of "The Atlas of Emergency Medicine" (2015) about 200 bucks..... I am new and currently doing family rotation right now, but will do ER later... do you recommend to buy both? or do you think I can buy ER one, do you think it can apply to family practice setting currently i am doing right now??? or ??? what you think? they are expensive.. I did research, but not useful results.. If possible, can you give me some advise plz, thank you very much in advance!!!

    1. I would probably read reviews on each and make that decision yourself. I'd hate to recommend one and it not be quality. If you plan on keeping it and using it for a long time, I would probably invest in the higher paying one if it is worth the money. Again, read reviews on each and decide whether you think the other is worth the extra $100. I would not recommend buying both, though.

    1. Hi GatorACE - great question! I'm actually working to format these into study guides for students. Give me a few more months and I should have everything worked out! Thanks for the motivation!
