Does B.C. have Coloboma in his Right eye?

As far as I know, he does not have this condition. He has what is known as centralized heterochromia. His eyes are blue/green, but have a ring of স্বর্ণ around the pupil, which makes his eyes seem to change রঙ based on his surroundings. He also has a stripe of brown in his right eye, which is what আপনি are referring to. It is just a discoloration due to the heterochromia, and not coloboma.
