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.

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

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
