    Binocular Diplopia

    At your age, giant cell arteritis must be ruled out. You also need an MRA STAT to rule out an aneurysm. Have your optic nerves been evaluated with an OCT for papilledema?

    Chloroquine

    I go to Honduras every 6 months with a group of 25 to 30 people for the last 4 years. No one has ever had a serious reaction to chloroquine so far. You do want to take some form of anti-malarial med. You don't want malaria. We do have patients die from malaria every so often here in Houston...

    tiny bubbles...behind my eyes

    I will start with the usual disclaimer. This is general education not specific medical advise. It sounds as if what you saw was more of a visual aura not floaters. Floaters go away when you close your eyes and or more noticable in your central vision. This would indicate more of a neurological...

    Scratched Cornea...safe to dive?

    This area is what I do and teach for a living. I will give some general information not specific medical advise. The cornea will usually heal in 24 hours from minor cuts or abrasions.. However, depending on the injury and your personal healing rate it may take longer. Diving with a corneal...

    Is there any extra concerns with divers who have HIV?

    I don't know if there could be complications from HIV Associated Dementia. Check out this link: http://www.emedicine.com/med/topic3151.htm A high number of patients will have it. Does the higher O2 concentration increase the damage? Does it make you more succeptable to seize? ADC alone could...

    Post LASIK- How long to get perfect clarity?

    Harley, It is impossible to say for sure if and when the halos will go away. The all laser procedure does cause more tissue inflammation which will take a while to go away. Each person is different. However, even with the best machine and surgeon, it is possible for you to always have halos...

    Hepatitis and buddy breathing

    To make things even more uncertain, about 30% of hep b and 15 to 40% of hep c cases have an unknown source of infection. It makes me wonder at times. Lloyd

    Hepatitis and buddy breathing

    I agree with Saturation. I have found an alarming number of patients who have hep b or c and don't know they have it. They also do not have any classic risk factors for contracting it. It is better to err on the side of caution. A regulator mouthpiece can irritate the gums and cause bleeding...

    Question for Opthamologist

    The chances of infection from salt water are very slim. From fresh water higher, but still small. Unfortunatelythe infections can be blinding. I advise my patients to use daily disposable lenses if possible. If not, I have them clean their lenses immediatley after diving with Miraflow cleaner. I...

    Thyroid Eye Disease

    This is an interesting question. The only thing that I could see causing a problem is if the sinuses are partially are totally blocked. In this case, the contents of the orbit could be compressed through the holes in your sinus walls created in the decompression surgery. I would consult an ENT...

    Blood sugar crash during diving

    You might try lowering your carb intake and increasing your protein intake. That will get your blood sugar up longer. The sandwiches and fruit have alot of sugar and carbs which kick your insulin up and cause you to crash sooner. Lloyd

    Eye Bleed and Diving?

    Were you dilated? When ever you are hit in the eye, you should be dilated to check for retinal detachment. You also need gonioscopy to check for angle recession which increases your risk of glaucoma. As for as the subconj hem goes, if you get a mask squeeze, it will really look bad since it will...

    Ruptured blood vessels in eyes

    It is not a mask squeeze from ascent. I would worry about the possibility of a blown out ethmoid sinuses from barotrauma. Does the tissue sort of crackle when she touches it? I would have it looked at by a eye doc. Lloyd This is general information not specific medical advise

    I am not a cardiologist, but I was wondering if the turbulance of the valve could possibly induce bubble formation? Lloyd

    Amitriptyline for pain?

    The half-life is 17 to 40 hours. I don't know how that would work for you. Maybe your doc would know. Lloyd

    Amitriptyline for pain?

    Sorry, no money or equipment for that area of research. It would be nice to have more done. The header is a little misleading. It is from an article for epilepsie docs, but the incidences are for "normal" subjects. They are still low, but worthwhile to think about. It might be worth seeing how...
