  2. No problem Vickie. I’ll add you to the list … but you’ll need to confirm when you get the email. The list is “double opt-in” to avoid the potential for spam.

    Thanks!

    You seem like a decent straight forward person, I appreciate that.
    I’m new to the industry. I work at Walmart and just spent my first day in the vision center. I have lots to learn and need to understand things as quickly as possible. I’m trying to understand the lensometer and the readings I’m taking. I’m trying to understand what Sphere, Cylinder and Axis represent. I’m still researching, but if you have something that can help me along the way that would be great.
    Sincerely
    Steve Solarz

  4. Steve, You might find a couple of video lectures of mine useful:

    Introduction to Optics (24 minutes)

    Using the Lensometer (2 minutes)

    Unfortunately, both of these videos were created for people using “positive” cylinder (and at WalMart, you’ll probably be using “negative”) but the first video should explain the difference. Good luck!

  5. Always great from Dr. Root. Meanwhile, still waiting for the video on how to simply use the Binocular Indirect Ophthalmoscope from your own perspective sir. However, if this already exist, can someone pls send me the link? Pls respond Dr. Root as I love all your lectures as they have made me a better student. Pls dont disappoint me sir. Thanks in anticipation. Regards, Ozone.

    Dear Dr Timothy Root,
    I’m very happy to receive your answer, and now, I would like to receive a little bit more about Amblyopia, especially exercises for training the lazy eye, easy understanding, easy doing and effectively.
    And besides, I would like to learn about low vision from easy to complicated theory and practice.
    Thank you again, and I’m always looking forward to you.
    Best regards.
    PHAN DANG LONG

  11. @PhanDangLong: I don’t have any lectures up on amblyopia, other than general review within my ophthobook pediatric chapter video.

    As for low vision, I don’t have much experience with this optometric specialty. Sorry.

    I love receiving emails from you Dr. Root! Can’t wait to download the new PDF #geeked

  13. Thank you so much Dr i really respect and enjoy your method of introducing ophthalmology lectures
    Waiting for the new book as pdf
    I hope you will present a lecture about eye tumor like retinoblastoma also a lecture about laser ophthalmology in diabetic retinopathy and its types stages i think it is a vital secton in ophthalmology
    Thank you

  14. Maryam, not bad ideas for lectures. I probably won’t make a retinoblastoma lecture (other than small discussion in my pediatric lecture) as it is very rare and I’ve only seen it once. I cover diabetic retinopathy somewhat in my old retina lecture, but I should probably redo it at some point. Right now I’m working on the first eye lecture at EyeTalkRadio. Thanks!

  20. very impressive. thank you for this insightful resource. definitely a must read for both medical and non-medical people alike.

  21. Plz enroll me in ur mailing list sir

  22. Dr. Root,

    What would you say are the differences between Ophthalmology and Optometry besides being able to perform surgery and prescribing oral medications? I can’t seem to think of any other differences.

  23. Eric, by your email address, I am guessing you are an optometrist. I think optometry is a wonderful field … I have the great pleasure to work with several and have encouraged my nephew to enter optometry school. As for the differences between ophthalmology and optometry, there are a few more I can think of:

    1. Enrollment Requirements: ophthalmology requires an additional four year medical school degree. While little of this knowledge is directly applicable to the eye, this multi-specialty background is very helpful for understanding neurology, rheumatology, and infectious disease. It also helps for coordinating care with other doctors, understanding lab values, and reading imaging studies (like orbital CT). Also, ophthalmology residency spots are fairly competitive … even if you kick butt in college, rock your MCAT and make it to medical school … there is no guarantee you’ll be accepted into an eye program (typically 16 people interview for each residency position). I am sure that optometry programs aren’t easy to enter, either, but ophthalmology is still a bigger gamble.

    2. Training: the emphasis on eye training is completely different. As I understand it, optometry schools do an excellent job teaching fundamentals in a class-room setting and try to expose their students to eye pathology in clinics and satellite offices. However, since each class of optometry students is large (143 each year at ICO according to their website) it is hard to expose students to a lot of live pathology. In comparison, my ophthalmology program had 3 residents a year … and all the sickest eyes from the entire state were shipped in for us to deal with (usually at 2am in the morning in the emergency room). Giant corneal ulcers, congenital defects, neonatal ROP, brain tumors … there is a lot more exposure to “sick eyes” during our training. The downside to this exposure method of learning, however, is that little of the “fundamentals” of eye care is actually taught in ophthalmology (we have no classroom training and are expected to learn these basics on our own time).

    I love both fields and think they are great. Optometry doctors are being produced three times faster than ophthalmologists … so your field is gaining more importance with population and insurance pressures. Optometrists are truly becoming the primary care doctors of the eye while ophthalmologists are turning into surgeons.

    Please subscribe me to the weekly email update. I’ve viewed a few of your videos (I plan on watching ALL of them now…I’m hooked). I also make education videos for my ophthalmology practice in Mississippi. I plan to use your vids to train new techs. Thanks for all of the hard work that has gone into these!!!
