This question is for all you differential diagnosis nerds out there! I have been experiencing a fairly rapid decrease in my vision over a course of weeks, and I notice inconsistencies with my vision throughout the day. The optometrist suggested this may be attributed to elevated glucose levels. However, my glucose levels were low (69). The CBC indicated high WBC, MCH, and absolute neutro with low EOS percent. I must acknowledge and inform you of increased stress and random headaches. I am a 23 year-old female at 5'2 and weigh 115 lbs (thought this might help). I am so curious about the relationship between this compiled data and how it may or may not contribute to blurred vision or even if it is related to something completely different. I would be thrilled to hear any brilliant opinions any of you may have. Thank you very much!!
I can tell you for a fact that your high white blood count, high neutrophil percentage and low "EOS" (eosinophil) percentage have nothing to do with your blurry vision. Also, it's true that some very high glucoses over long periods of time can lead to blurry vision, but with a reading of 69, that certainly would not be a cause.
The MCH is basically a measure of the size of your red blood cells, and even if high, does not relate in any way to blurry vision.
Taken altogether, the only thing this blood work may suggest is a nonspecific infection, but can also be normal (I don't have the actual numbers). It's likely there is nothing that can be diagnosed with these lab values alone.
As to what is causing your blurry vision, no way to know, and definitely no way of knowing with just this lab information. If you are truly having waxing and waning visual deficits, a visit to the ophthalmologist (not optometrist) would be more appropriate.
Well, again, just a little something to remember the good times, the bloopers, the filming! Here are some of the best moments -- the outtakes. Kit ...
I've got an unusual eye condition where my left eye is very longsighted and my right eye has perfect vision. And because of the huge difference between the two eyes I can't just get a prescription for my left eye, because my brain can't cope with the difference, and everything just seems a blur.
This means that my eyes strain a lot more easily than usual, and recently when I got an eye test at a glasses shop, they gave me glasses with prescriptions for both eyes so that they can "complement".
I'm just worried that the glasses will damage my good eye if I wear them. Should I wear the glasses or not? The only difference I'm noticing is that everything seems a bit bigger, but according to them it could relieve the strain on my eyes. I visited a proper optometrist not too long ago, and he didn't give me glasses because he says they wouldn't help much.
Any optometrists or other eye doctors who can give me some advice? Thanks so much!
By the way, I'm a teen, so my eyes aren't getting worse because I'm getting old.
If you wouldn't mind, can you please explain why?
I know this feeling. My right eye has normal vision and my left eye has moderate astigmatism. I was given an eyeglasses prescription when I was a little younger than you, however I did not start wearing corrective lenses regularly until I was in my 30s.
I had issues when I attempted to wear eyeglasses as teen. I would get dizzy and my vision appeared slanted. I gave up on wearing eyeglasses again until I started getting headaches and double vision.
My doctor recommended trying a contact lens for my left eye because there is less image distortion and objects appear closer to their actual size. I suggest you ask about a contact lens for the longsighted eye. It may be a better option than eyeglasses for your situation.
I suggest trying out the eyeglasses to see if they help you, you do not have to wear them all the time, but it would be a good idea to wear them for near work such as reading or using a computer. You should not harm your normal eye by using them.

To any optometrist: I am a senior in high school, and I am graduating in the top ten percent of my class...I have already accepted my admission to Texas A&M University...right now i plan to get a bachelours degree in biology(B.S.). How hard is it to get a bachelour of scinece degree? Should i get my bachelours in something else? And how difficult is it to go to eight whole years of school? how did you stay motivated to get through it all? What are the pros and cons of being an optometrist? What do you love about the job? Can i specialize in something? What is a Low Vision Specialist? I love the human eye, and working with people, but is it really worth eight years, I don't know if i can handle that much school...please help
I found the most authoritative answers to many of your questions here:
http://www.opted.org/info_faq.cfm#18
As for keeping yourself motivated, I'm not an optometrist, but I did complete far more than eight years of school on my way to four degrees including a PhD. If you love the work, you'll find it gets easier and easier as you move further along in it--especially once you have finished general education and pre-requisites and are concentrating entirely on work in your career. Let's face it, if you're up to doing optometry for 35 years of your life, the four years of optometric school beyond the bachelor's degree will be not nearly that long and will involve much of the same sorts of work.
I've seen too many answers about optometrists vs ophthalmologists, and people claim that optometrists aren't doctors and can't treat any eye diseases. This is FALSE. Optometrists receive a Doctor of Optometry degree (O.D.) and are commonly referred to as the "eye doctor". It takes 4 years of training after undergraduate college to earn this degree. Optometrists are also well-trained to treat many eye diseases, including infections, injury, and glaucoma. For example, if you have a corneal ulcer, an optometrist can treat it with medication. They can also monitor patients who have diabetes. They also work with low vision patients and patients who have bincular vision problems. Optometrists are also trained to know when to refer to an ophthalmologist for surgery.
So my question is: Why don't a lot of people understand what an optometrist does?
ignorance
What type of glasses does an optometrist usually recommend for a post RK (Radial Keratotomy) that uses a computer a lot? I've noticed problems with my vision in low light conditions. Can it be that I use the computer for too many hours? I have a CRT graphics monitor (LCD was too bright for me) and I currently use some glasses with yellow lenses that are supposed to be for computer and night-driving. I have about 6 incisions per eye.
Please don't just say, "ask your optometrist". I need some informal advice and opinions please.
To minimise glare effects, you want a reasonably high level of ambient lighting, and the contrast/brilliance on the screen only just high enough to give clear resolution of the letters.
(more is not better at that point)
A tinted glass is not really indicated, but a good anti-reflection coating is.
Unless you are working with copy material, or other reference documents, a single-vision lens set to suit your accommodation and the screen distance is normally the best.
If you are presbyopic, and have differing distance requirements, office varifocals or intermediate/near executive bifocals could be the best set-up.
Here it does really turn on individual considerations and working distances.

What are the best journals which publish low vision research ...
A PhD student in our lab is submitting her first paper in the low vision field and we were discussing where she should submit it so that it reaches the right audience. This led to quite a long conversation about what journals publish what type of low vision research. This post gives my subjective “top ten” low vision research journals, and my impression of which journals tend to publish which types of low vision research.
1: OPTOMETRY & VISION SCIENCE I think OVS is currently the best journal for low vision research. Their papers tend to be clinically relevant and focus on reading, low vision devices, and quality of life research. Their readership is largely optometrists (it is the journal of the American Academy of Optometry) but papers I have published here seem to be cited by non-optometrists. International readership.
