Just a note on colomba. For the sake of accuracy, and therefore credibility, it would be good to discriminate between colomba and sectoral or segmental heterochromia iridum. Colomba is distortion of the actual pupil: https://duckduckgo.com/?q=coloboma&t=ffab&iax=1&ia=images Segmental heterochromia iridum is a difference of color in one segment of the iris (scroll down) https://www.crutchfielddermatology.com/caseofthemonth/studies/2013/l_2013_008.asp According to mainstream medicine, this is attributable to either congenital or other causes such as injury or illness. I believe both Hunter Biden and Madelaine McCann are cases of segmental heterochromia rather than colomba (see their photos in next paragraph).

The potential interest to our investigation lies in the alternative medical field of iridology, which locates areas of iris discoloration on a chart corresponding to different body parts.
