I wokeup weeks ago&my vision was darker colors looked dull.That has gone back to normal but vision stayed blurred Eye doctor can't find anything wrong?

Motto: if an eye Dr.: Can see in, and the patient can't see out, then have a neurologist look into this, or neuro-ophthalmologist to make sure it's not something more serious like MS. Dark colors and blurred vision is not normal. Get a 2nd opinion. It's your eyes! You want to have them for life! ...Read more

Is it normal for eye vision to worsen a few weeks after corneal transplant surgery?

Is it normal for eye vision to worsen a few weeks after corneal transplant surgery?

Yes: I see this most commonly in keratoconus grafts where initial swelling causes graft flattening. As the swelling goes down the graft steepens and becomes more myopic. Of course any transplant can have a change in refractive error and astigmatism as it heals. I would not worry about rejection this early but if there is any pain or increase in redness or light sensitivity i would see your surgeon now. ...Read more

I have a burst blood vessel in back of eye (seen specialist all test back normal- perfect health) no vision left eye, how long for return of vision?

I have a burst blood vessel in back of eye (seen specialist all test back normal- perfect health) no vision left eye, how long for return of vision?

Depends on cause: If the burst vessel released blood into the back of the eye, recovery depends upon how rapidly the blood is re-absorbed which may take 1-2 months. If it is a vessel that supplies a critical portion of the vision, there may be some permanent loss. These are all modified by whether or not you have diabetes or a vascular disease like coats disease.;. ...Read more

Blurry vision, constant eye floaters, flashes of light, double vision. MRI normal & saw 2 eye doctors who found nothing. What can it be?!

Blurry vision, constant eye floaters, flashes of light, double vision. MRI normal & saw 2 eye doctors who found nothing. What can it be?!

Talk to your doctor : You may want to see a neuro -ophthalmologist. Your symptoms are very concerning. It's possible to have normal exam and negative MRI and still have something wrong. Multiple sclerosis comes to mind. You may find a specialist in New Orleans to evaluate you and hopefully ease your mind. ...Read more

Hi when im watching tv and when im resting my eyes my vision becomes all white and then it will be gone for a second and back to normal vision?

Hi when im watching tv and when im resting my eyes my vision becomes all white and then it will be gone for a second and back to normal vision?

See MD: Your symptoms are worrisome enough to recommend seeing an ophthalmologist. When it comes to your eyes, it is best to "be safe rather than sorry", and some vision disturbances need to be treated as soon as possible to prevent permanent damage. I know if that was happening to me, I would be on the phone with my eye doctor right away! ...Read more

When i go outside in bright sunlight, it takes my eyes 5 or 6 minutes inside to get to normal vision-i can see clearly, but it seems like it's darker?

It takes time: Some people can have trouble adjusting from light to dark conditions or vice versa. If your vision is otherwise normal, it is probably not a serious condition. There is a group of rare retinal conditions, however, that can present with similar problems that can lead to decreased vision. In order to determine if you may have one of these rare conditions, you need to have a dilated eye exam. ...Read more

If you can read an eye chart at 20ft as well as a person with normal vision at 30ft is vision 20/30?

If you can read an eye chart at 20ft as well as a person with normal vision at 30ft is vision 20/30?

Visual acuity: Now a person with "normal" eye sight should be able to read the row of letters of a certain size ( the 20/20 line) standing or seated 20 feet from the eye chart as any person with normal vision should be able to do. Yes, your vision would be 20/30 if you can only see the chart at 20'. But if you can also see it at 30', you would have 20/20 vision. ...Read more
