Since birth i have had what looks like a pizza slice missing in my pupil, after having tests done as a kid i was told it was my pupil stuck to my lens, however since being old enough to look online i found out that this cant be the case or it would be causing me problems. it doesnt affect my sight, just slightly stings if i go from bright to dark light too quickly. i dont think its synechiae as its my pupil not my iris.

any opticians out there who could help?
