    i like the idea of OPHTHOBOOK an i found it interesting and easy to understand. But apart from its goodness, its not complete. like you see in topic of glaucoma, there is no description about the visual feild defects occuring in different types of glaucoma. It must includ other topics like scleral diseases and many others.
    in last i just want to thanks the OPHTHOBOOK as it has helped me alot!!!

    Editor’s Note: Thanks for commenting. The purpose of this book is not to be an all inclusive textbook of ophthalmology, but to present these introductory topics in a simple and digestable format. Part of the challenge for me was to keep the chapters short – I had a very hard time keeping the book under 165 pages, and sometimes wish I’d made it shorter. I think this brevity is what makes this book useful and approachable. Some topics, such as the appearance of the glaucomatous visual fields that you mention, are just not high-yield topics for the neophite (though I do discuss these things in the videos). Also, other topics such as the scleral diseases (which are always highly covered in traditional texts) are not very important to the new student, either – I haven’t seen a case of scleritis or episcleritis in my clinic for at least six months. Any student going into ophthalmology must read larger (and more dauting texts) for this detailed information. Thanks for the constructive critisism!

  4. Simply excellent…
    simple but descriptive pictures for creating clearer concepts…

  5. Another helpfull video 🙂

    Any chance of another video or document outlining the glaucoma drugs in more deatail. I get soo confused trying to learn them all and make a real mess of trying to answer Qs about them in exams.

    Thank you for taking the time to teach us

  6. On question 13, I believe that you meant to put VEGF rather than VEFG for the answer. Just wanted to let you know in case there is another publication. I love your book!!!

    Please help. I am alarmed at the light that suddenly appears outside the rim of the lower eye. It looks like the eyelid itself with light in it. Sometimes my eyes are closed and I can still see this. It is now occurring with the other eye. I could be watching TV and reading a book and this occurs. Is it glaucoma. My family have glaucoma
    Thank you

  13. THANKS DOCTOR..
    I LOVE IT..
    CARRY ON..

  14. many thanks for your wanderfull site, its a good learning site for medical students and those who wants to specialise in ophthalmology

  15. Thank you very much for these important notes

  16. Hello! I just got some questions about glaucoma..

    When you say that glaucoma risk factors include family history, it is also important to screen for patients without any symptoms and with a positive family history for glaucoma.
    But who exactly do you have to screen and when is it necessary to screen? eg. Girl, 22 years old and without any eye symptoms. Father is diagnosed with primary open angle glaucoma.. Necessary to already screen the girl at this age?

    IOP is normal between 10 and 21 mmHg, but is it possible to have an IOP of 0 mmHg? If so, would it cause damage? If so, is it possible to ‘overtreat’ patients with glaucoma by use of any medical treatment?

    Thanks alot!!

    PS: your website is great!

  17. Fantastic resource – we are doing optho right now and the lecturers tend to leap right into the small details and present them fairly dryly. Having this has helped greatly by providing a good foundation from which I can plug in the other smaller details I will need to memorize for the exam and then promptly forget… I’ve informed my classmates of this site and they have all been very impressed with it as well.
    Thanks again,

    this is really a piece of art in presenting the glaucoma case thank u so much

  19. I have a rare condition known as congenital ectropion uveae, which has created a problem for me of acute angle closure attacks. I would love to hear your understanding of the condition and how it affects the people who are plagued with it.

    Thanks.

  20. it would be even better if information regarding changes in visual field due to open angle glaucoma would have been given…

  21. Thank you for your information. I recently had an exam where my IOP is 17, (appears to be normal range), discs are noted as flat, I have no family history of glaucoma and don’t fit the description of a glaucoma patient, yet my doc says he’s worried about it and wants me to come back for more tests. I’m skeptical and don’t like unnecessary testing.

  22. First, I think your sight is spot on. Great job! Below is a short explanation of my experience. I hoe this is helpful to any current or future doctors. There is NO history of glaucoma of any kind in my family.

    Topamax is BAD news. I went blind in 11 days on 14.5 mg (I cut the 25 mg pill in half) of Topamax. It caused acute angle closure glaucoma, with glaucoma flecks too. The sad thing is I was hospitalized twice and NO ONE looked at the side effects of the medication. Both times I told them it felt like an ice pick was being poked in my eye and that my vision was blurred they did nothing about it. Then after I went blind, the doctors (not ophthalmologist) said I went blind due to stress and continued to give me Topamax for 5 more days before they had and ophthalmologist see me. Who within hours figured out what had happened.

    It is now over 8 years later and I am still blind. I share this with you so that others will be sure to check the side effects of the meds people are on. I was the 25th person the FDA said went blind as a direct result of Topamax.

    Just like you said the pressure had to come down. I wouldn’t wish that pain on anyone. Laser surgery was done immediately after 5 different types of drops (that felt like acid) didn’t work to lower my eye pressure. Both my irises remain stuck dilated open, so when my eye pressure went down it caused all light to come in. Now and I guess you can say I am blinded by the light. Please remember to look at the uncommon side effects of meds that a person is on. I having never seen my grandson who just turned 5 years old, nor my youngest daughter since her third birthday she is now almost 12 years old. It has been very difficult. I pray your information gets to all those who need it. If I can help in any way please let me know.
    Blessing to you always.

  23. it is liked the coolest sit ever i luv it =DDD

    simply superb…..

  26. Thank you very much for this wonderful ophthalmology textbook and I like the sense of humor of the author. But I think there is a typo that the measuring unit of corneal thickness should be ‘μm’ rather than ‘nm’. Thanks again!

    Hi,

    You have done a great job with the web site.

    We are preparing a patient information booklet on Trabeculectomy for our glaucoma clinic. This is just for helping our patients and without any personal financial interest.

    I will be most grateful if you would allow us to use one of the diagram on trabeculectomy for the same.

    Please will you let us know.

    Kindest regards

  34. Optic disc may be sinking in glaucoma, not cupping. Sinking of the disc implies a mechanical failure. As a result of sinking disc the pre-laminar nerve diners are stretched and then severed. Thinning of the RNFL, selective destruction of arcuate fibers in the early stage of glaucoma and histology of end-stage glaucomatous disc of empty bean-pot suggest that the nerve fibers are being severed, not atrophied in glaucoma. Glaucoma may not be optic disc neuropathy but an optic disc axotomy.

    Amazing resource thank you for your hard work!

  40. Thank you so much for doing this! I’ve started my residency one month ago and this book has been my best friend so far! I feel more comfortable and integrated because of it!

  41. Corneal thickness is 540 micrometers, not nanometers

    1. You are correct. I’ve updated the text (at least on the site … I’ll have to fix the print/pdf with future release). Thanks!

  42. This is an amazing resource! And the fact that you have made it free speaks volumes about your character and passion for medical education! THANK YOU!
