Detailed Answer:
Hello
Welcome to Health care magic

I am Dr. DADAPEER K, an ophthalmologist and I answer health problems related to eye.

It seems from the history that you are having decreased blinking of the eyes. Decreased blinking of the eyes is usually because of weakness of the orbicularis oculi muscle which is responsible for blinking. You need to use artificial tears eye drops in this condition to prevent dryness of eyes.
Please give me more details like
Do you have decreased blinking of the eyes?
Any other problem like watering, redness, pain, dryness, diminution of vision?

Please do mention answers for the above questions so that I can answer your question more accurately.

Thank you

It is like it is black for a second as though you blinked your eyes closed, but don't recall blinking them. No to other questions. Don't know what diminution of vision is.

Brief Answer:
It indicates a transient loss of vision.

Detailed Answer:
Hello
Thank you for the follow up question.

Sorry I got your question correct now, it seems from the history that you had a episode of sudden black out of vision which lasted for a second.

It is called as transient loss of vision or amaurosis fugax. It is caused by transient ischemia and it typically lasts for few seconds with complete recovery.

The common causes from the eye causing transient loss of vision are prodromal symptoms of retinal artery occlusion, vascular diseases....
Since you have undergone eye examination and it is normal it rules out causes from the eye.
The common causes are aura of migraine, dizziness, hypotension, hypoglycemia.

Just look for any of the above mentioned causes and if any one of them are present correction of the underlying problem is sufficient

If the condition is recurrent it requires systemic evaluation to rule out vascular diseases affecting the carotid arteries.

Since your eye examination is normal you need to consult your physician if you have recurrent episodes of black outs of vision.

Hope I have answered your question and the information is helpful to you.

Thank you
with regards

Do consult your physician for examination.

I did have my carotid arteries checked about 1 yr. and a half ago and all was fine. Should I be more at ease since that was the case?
doctor
Answered by Dr. Dadapeer K 7 hours later
Brief Answer:
No need to worry as carotids are normal.

Detailed Answer:
Hello
Thank you for the follow up.

Since carotid examination was normal you need to worry. Once the eye conditions and the vascular causes of the carotids are ruled out only benign causes needs to be considered like aura of migraine, dizziness, hypotension, hypoglycemia...
You need to worry about them and need to get evaluation if the episodes are recurrent.


Hope the information is helpful to you.

Thank you.

Even if it was about a year and a half ago since they were checked?
doctor
Answered by Dr. Dadapeer K 2 hours later
Brief Answer:
First common causes have to be ruled out.

Detailed Answer:
Hello
Thank you for the follow up question.

The involvement of the carotids has to be suspected after ruling out the common conditions like migraine, dizziness,hypotension and hypoglycemia.

Only medical examination to look for bruit which indicates any obstructions of the carotid is sufficient if you have undergone previous examination of the carotids by ultrasound doppler.

Hence I advice you to consult your physician to rule out these common conditions and then you can think of rare things like vascular diseases of the carotids.

Hope the information is helpful to you.

Thank you

Hello, I am a 44 year old male who, until relatively recently, has been very fit all of his life, playing various sports, particularly football until only a couple of years ago. My problem started at the beginning of 2009 when suddenly I lost all vision in my right eye. There was no pain and no warning signs this was going to happen as I had no previous health problems. This lasted for about 3 mins until the vision returned as quickly as it went.
I had a number of similar episodes over the next few months including what I can only describe as a curtain dropping down in my eye (always the right eye). I was examined by various specialists and was diagnosed with Amaurosis Fugax and placed on medication (aspirin and ezetimibe). Afterwards I felt that my physical strength had diminished a little but still felt relatively fit.
I was free of any further symptoms for 3 years until a similar episode of loss of vision in September 2012 and after further examinations my medication was changed ( chlopidigrel and rusovostatin). I felt that I was getting tired very easily and was finding it hard to concentrate at times. Again I was symptom free for about a year until I suffered a further loss of sight in my right eye (October 2013). Not only did I lose my sight, I also lost coordination in my legs, I had 'tingling' in my right fingers and leg. I was admitted to hospital where I was told I was having a stroke. At this point I felt completely drained of all energy, I was sleeping most of the day, I had no strength in my arms or legs and was extremely 'moody'. Over the next few weeks I underwent further examinations including a transoesophogal echocardiogram and it was discovered I had a Patent Foramen Ovale (PFO) which it was explained is a 'hole in the heart' and was probably where small blood clots are forming.
I underwent an MRI scan recently and it was found I had a 'white spot' on the left side of my brain which was explained May be a restriction in the blood flow. I have been referred to a cardiologist and a neurologist for further consultation but I have to wait a significant time before my appointments. I am extremely worried as I have never had anything like this before, I am not allowed to work (I am a police officer of 23 years with minimal sickness) and do not know what is likely to happen.
Any advice would be welcome.

Kind regards,

Eamonn

I have had a couple of total white outs in my right eye that lasted about 15 minutes and then gradually returned to normal like a veil being lifted from the bottom. I was resting at the time and the white out was instant. No pain but I was very dizzy when I stood up but only for a for a few seconds.
