I am female, in my early 60's, nearsighted, have cataracts
on the edge of the lens
of the eyes. Other medical conditions are as follows: I have hypertension that is being treated along with Hishaimoto Thyroidisis. Recent blood work showed a slight elevation on the ANA test, which is under further evaluation at this time.
Three years ago I started to have afterimage problems. I can look at anything and I immediately see the ghost of it and it quickly disappears. I consulted a top neuro-opthamologis, who conducted various tests and he told me everything was fine. In April 2013, I went on my own and I spent an afternoon being evaluated at Hopkins Wilmer Nueuro-Ophtomology clinic. They conducted a battery of eye tests and a neurological exam and everything was fine. No further testing was recommended.
Recently, I started to have some balance issues so I consulted with an ENT doctor. At my request, in July 2013, he sent me for an MRI. The MRI with contrast showed a 4mm rounded focus of increased signal intensity within the posterior aspect of the right corona radiata with subtle enhancement. I am waiting for a follow-up MRI in September 2013, and then it will be determined if this was a sub-acute infarction, active inflammation/dmyelination, or a vascular lesion. The neurologist that I consulted with informed me that the MRI finding does not match my symptoms of the afterimage issue or my balance problem. He seems to think I had a mild stroke because my blood pressure has been elevated.
In the process, the ENT doctor also sent me for an ENG test last week (August 2013). The results were that that I have central vestibular pathology due to abnormal tracking and optokinetic and directional changing nystagmus
seen during caloric testing. All the other occulomotor tests were normal. The ENT could not give me an explanation for this finding and he sent me along to see the neurologist. I have an appointment this week with the neurologist. From doing research, as best I can, it seems to me that the ENG test picked-up that my eyes go back and forth when looking at objects. I have a long standing problem that when I talk to folks I look all over the place and I cannot focus on their faces.
I don't know how to interpret the ENG findings in view of the fact that I do not have any eye diseases except for the conditions that I noted. The MRI results to me do not seem to support the findings on the ENG of pathology in the parts of the brain that affect the central nervous system such as the cerebellum. Any information that you can give me about interpreting the ENG results will be greatly appreciated.
