Begins With Kaleidoscope Type Blackness, Then Complete Blackness, Black Shade In The Eye. Fatigue, Emotional Stress. See Neurologist?

This is the second time that in my right, it begins with a kaleidscope type blackness and then complete blackness lasting for about 1-2 minutes. As the blackness begins to dissipate, it is as if a black shade is drawn from the top to the middle of my eye. The first time the black shade was from the bottom, half way up. No headache , perhaps a little pressure on the right temple side. I have fatigue and emotional stress . Should I go see a neuro or an eye doctor?

Ophthalmologist,  's  Response
The symptom you describe is similar to a condition called Amaurosis Fugax or Transient Monocular Vision loss. These include a group of conditions, some relatively benign and some not so much. Common causes are a Transient ischaemic attack or stroke, carotid artery stenosis, ocular disease, migraine and sometimes unknown. The problem with this is the complaint does not exist at the time the patient visits the ophthalmologist and the retina appears normal. A careful history is important and tests have to be done that evaluate the function of the carotid artery with a carotid doppler, blood tests and even an MRI.It is important to start by visiting your eye doctor who will probably order a few tests to evaluate your condition. General measures to tackle this situation include addressing risk factors like smoking, hypertension, diabetes, obesity ,hypercholesterolemia and carotid arrythmias.
