Re: Tortuous Blood Vessels
You say no other doctor has mentioned it, but wouldn't the doctor have to be an ophthalmologist to have seen it? Maybe not. I just had a physical yesterday and the GP looked in my eyes with a light.
Anyway, perhaps you should go with the "normal variant" explanation. I found this from a study of healthy people:
Of 218 subjects, 79 (36.2%) had straight retinal arteries, 110 (50.5%) had wavy arteries, and 29 (13.3%) had tortuous arteries. Heritability of tortuosity was 82% (CI95 64, 92%), with unshared environmental factors accounting for the remaining 18% (CI95 8, 36%). Increasing values of mean arterial blood pressure and body mass index were both associated with decreasing levels of retinal arterial tortuosity.
Conclusion: There was a large variation in tortuosity of retinal arteries in these healthy subjects and the predominant determinant was genetic influence, accounting for 82% of the observed variation in tortuosity.
