I had a routine eye test yesterday and the optician showed me photographs of my left eye showing a bleed next to my optic nerve. She’s referring me to the hospital and said it could indicate glaucoma. I’m 43 and don’t have a family history of this. I feel like I didn’t really ask enough questions about what it might mean and now I’m feeling rather anxious about it. Are there other possible reasons for the bleed? I’m worried I’m going to lose my vision.
