I am a 69 year old man visiting the US, and am experiencing eye problems. I appreciate your advice on probable causes for my problem.
In the last few months, I have occassionally experienced transient shifting of the focal point of my right eye. During this period, my left eye focus continues to be fixed, but my right eye focal point drops. This leads to temporary experience with dual vision till the two focal points merge. In general, the entire episode lasts for 5 - 10 minutes, however occasionally it can take up to an hour. This leads to significant discomfort, esp if I am outside.
In terms of medical history, I am diabetic but my blood sugar has never gone north of 200. I also maintain a tight regimen of diet and exercise of vigorous walk and yoga. Furthermore, I was operated for cataract and retina detachment for both more than 10 years back.
Do you know what might be causing this problem? Any help is much appreciated. Thanks.
