These symptoms indicate transient ischemic attack.

Detailed Answer:
Hello
Welcome to Health care magic

I am Dr. DADAPEER K, an Ophthalmologist and I will be answering your question.

I reviewed your history. It seems from the history that you are having blurred vision/ dark spot in both the eyes which is improving gradually.
This indicates a probable transient ischemia.
The common causes that needs to be ruled out are hypotension, hypoglycaemia and hypovolemia.

Hence I advice you to consult your primary care physician to rule out these common causes by simple tests like measurement of blood pressure and blood sugar examination.

If these are normal and if the episodes are recurring then need to rule out vascular causes like atherosclerosis, vascular occlusion...

Hope I have answered your question and the information is helpful to you.
Do write back to me for further questions.

Thank you
