    Excellent! Superb! The Author transferred the more complicated subject to much more simpler one. ‘Piece of cake’. I recommed this site to all medical students and practising Ophthalmologists and Optometrists.

    Nice. Ophthal made easy 🙂
    thanks alot

  6. wonderful!thanks alot.

  7. please tell me, if a patient with a pupil that doesnt dilate as much as the other, with the difference being at least 2mm, and the cocaine test dilates the eye, what else could it be?

    Sir,

    On the action of superior oblique in your video lecture, I get this doubt. When the right eye is abducted the right superior oblique intorts the right eye. When the right eye is in primary position(gazing straight) the right superior oblique will again intort the right eye. Would you say that comparing the intortion in two scenarios, the intortion in a abducted eye will be more than the intortion in a primary gazed eye?

  11. I was wondering what could cause my grandmother in her 80’s to experience double vision, crosseyes, massive headaches…it was mistakeningly diagnosed as temporal arteritis but on further examination of the piece of artery they extracted, was that it was healthy and was not temporal arteritis…The Doctors are baffled this is her second time in 10 years with the same symptoms on the same area…Any thoughts I just wanna see her get better quick

  12. this was really helpful. i’m still struggling to figure out my intermittent vertical double vision – binocular. i’m 50 yr old female. it occurs in the a.m. and last approx 90 minutes. it’s been 2+ years.

  13. i only wish i had visited this site earlier, hats off to all the people behind it

  14. Thank you so much. This is a wonderful resource.

    Ran into a tree doing 80km was in a coma for 5days have no memory of accident have problems seeing and have a big problem eating I can’t have anything cold as my lips feels like they are frost bitten and inside my mouth it is very painful when I chew instead of taste I feel like electric impulses. When I drink it is painful I can only drink warm tea, water at room temp starts this electric charge in my mouth.I can not walk easy, on uneven ground it is about impossible it feels like the ground is moving around me. I feel like I am in a different reality. I have seen all sorts of Specialists and one says 4th nerve Palsy!No clear answers. Do you have any suggestions? Thank you

    I have had keracatonus for30+ years and in the past few years being tested for Ms do you think there is a link there. I am vittualy blind now

  17. My left eye is so much smaller than the right eye not only that but my pupils dont move unless i move my head from side to side i dont even blink much. What could be the problem what should i do ?

  18. Im a 57 year old woman with 4th nerve palsy which came on suddenly 1 year ago. May be a congenital condition with decompensation due to stress, as some earlier photos do reveal a head tilt. I wear prism glasses which help–but fatigue and any alcohol send me into double vision hell. Am considering surgery–and wonder on chances of success?

  19. M Hoffner says:

    57 year old woman with vertical double vision in both eyes. Worse with fatigue. no ptosis. Letters on page align with tilting head back. Many articles talk about a side head tilt but not the tilt straight back. What does this suggest?

  20. This is a great resource. Thank you.
    Question for you – Diplopia, Paragraph 2, Sentence 2 – Is it supposed to read the way it does? I am not tracking. Please review at your convenience.

    thanks ^^
    great book

  22. This is the most amazing website I have ever come across. Why didn’t I found this during my first year of university?!

  23. Martha Meek says:

    My husband has undiagnosed double vision in one eye only. He gets in intermittently for periods of weeks or months and then it goes for up to 8 or so months. He is struggling to see the right person, being sent back every time to see opthalmists who do the same tests, each time concluding that there is nothing wrong with the eye. Can you help in any way by letting me know who would be a good specialist to contact?

    Hello,

    I have a scenerio for you if you would be so kind as to share your input on the subject. I am a 58 year old female with an approximate 3 month history of severe headache, noted mostly on awakening in the morning. Headaches are so severe I refer to them as “brain thumpers” as I can also hear and feel my heart pounding in my ears when they occur. I have a history of some mild to moderate hypertention and have had an ablation for SVT a few years ago. Approximately a month ago I noticed that my right pupil was not centered in my eye when I was looking straight forward. I noticed it while looking in the mirror when doing my hair. I thought it was my imagination at first and then my son in law noticed it one day and said something to my daughter about it. The right pupil is pulling to the right side (or outer aspect) of my eye and sometimes appears to be pulled slightly upward. I sometimes have mild pain on movement of my eye and often feel like I have to blink a few times to focus my vision. I have had a few episodes of double vision as well. In general I feel terrible. I am very fatigued and of course realize I am more than likely suffering some anxiety over my eye and headaches. My neck feels stiff pretty much all day everyday. I am on B/P meds as follows metoprolol 50 q day, Losartan 50 q day which was just increased to 100 mg yesterday due to continued elevation of my blood pressure which has been ranging from 160’s to mid 170’s systolic and from high 80’s to low 100’s diastolic. I have had a CT scan to r/o brain tumor and/or aneurysm. I am scheduled for an MRI, MRA, and MRV next Wednesday and scheduled to see an optomologist in the coming days- though the appt has not been set yet. What is your impression, given my symptoms, as to what the issue could be? Signifcant family history includes mutiple incidence of aortic aneurysms and aortic dissection. 36 year old brother deceased from aortic dissection, two sisters who survived aortic dissection-(both when they were 49 y.o.) one of which has dissected 4 times, an Aunt deceaseed from ruptured aneurysm, 2 cousins deceased from aortic dissection/ aneurysm, one of which expired post repair when his repair “let go”. My materal grandmother is said to have died from cerebral hemorrhage at he age of 49 though records are difficult to retrieve to substantiate.

    Thank you,

  25. I’m in my final year at medical school. I think opthalmology is definitely my weakest point and I is not something I have ever had a huge interest in. But I decided to overcome that and I am sooo grateful I found this book! It’s absolutely fantastic!

  26. I have been diagnosed with sixth nerve palsy, it has got slightly better, how long will this take to be perfect.? Does ice, botox etc help or do you have to have the muscle stitched as the nerve is not sending the right signals

  27. 75 year old male, cataract surgery Jan. 20, 2013, left eye, Alcon Toric lens. In recovery room, noticed that vision was excellent except tilted down from right to left, approx. 5 deg. Advice was to get right eye done, see if brain corrects problem. Right eye done Mar. 13. After 3 months now, no improvement. Neuro opthomologist confirms surgery properly done, says wait 6 months. Says may be trauma to 4th optic nerve during surgery.
    Any advice or other observations?
    Thanks

    I am a 60 year old male with crossed eyes caused by a head injury. I was struck from behind by a car while riding a bicycle to work. I went up over the hood of the car and my head hit the windshield. I was unconsisous for some time. I have recovered in most ways. But I am still cross eyed in my left eye. It looks to the right down and leans to the right. I can align both eyes left to right, up and down. But as soon as I do the left eye’ s vision fades, and move back to the right and down again. When I first start trying to align them I felt a sharp pain in my left eye. But fortunately that has stop.
    When I walk in the mornings the street appears to lean to the right in my left eye. My right eye is okay. Maybe leaning to the left just a little. But I can use it for getting around, riding a bike and mowing grass.
    Since the accident in October of 2005 I have tried many eye exercises for improving my eyes. But since I am crossed eyed, I also have recurring lazy eye. Even though I can build up my vision from time to time. My lazy will pull it back down. I have always been able to straighten them up left to right and up and down, but never able to correct the left eyes’ s slant to the right.
    One more thing, I have retina pigmentosa. At the time of the accident. I had a 20 percent field of vision. I know it did not cause the crossed eyes, but it sure is not helping. Since that I have found eye exercises that help it a whole lot and I do mean a lot. I have a wider field of vision, and my night time vision has improved wonderfully. But I am still crossed eyed. It is really been a problem for me. Is there any eye exercises for the leaning problem in the left eye? Any help would go a long ways, and be appreciated even more.

    Thank You for Your time and Consideration

  29. I am not sure my condition is covered here.
    My problem is I see the same object with both eyes,for ex. a square drawn on a white sheet of paper. My right eye always sees the square as it should. My left eye sees the square and it is tilted to the right. If I raise my head i can get left eye square to cover the right eye square. But if I lower my head the tilted square goes down and to the right.

    Hi,
    I see that the last comment was posted in November 2013 so I hope that I am not late for the much needed help.

    I am 47 years old, and have suddenly and recently (past three weeks) experienced ptosis in my left eye lid and restricted movement in the right eye causing diplopia in the low to full right gaze. I also feel lightheaded and walking and focusing is quite hard without closing one eye. My eyes are healthy ophthalmology wise (according to the latest exam) apart from astigmatism.

    My blood tests are very good including thyroid. My MRI shows nothing. STIMREP and SFEMG tests show only slight intermittent delay in my facial muscles around the eye (something is 27% and it should be below 23%) but the rest are very normal. the neurologists suggested Ocular Myasthenia and put me on Mestinon and for last seven days I see no improvement. My chest Xray is normal. Tried acupuncture, no improvement. Diplopia is constant and does not improve with rest.

    I am (or rather was) healthy with good diet and regular exercise.

    I would very much appreciate if you would be able to suggest any other tests I should do to diagnose the problem and eventually treat it.

    Thanks and kind regards

  31. It is possible to have the author information for a MLA citation from this web page ?

  32. made matters very INTERESTING and is useful not only to students but to seniors also.ingenious illustrations.
    all the best

  33. Macular pucker in one eye can also cause double vision. That’s a defect in the retina, not a nerve problem. I have it. Membrane peel surgery six months ago has provided a return of sharp vision but objects still appear displaced, distorted and larger in one eye than in the other.
