My mum is suddenly seeing a large black spot in her right eye. Should she go to the emergency room?

Thank you for your recommendations everyone . I live in the U.S. but my parents live in France. My mum had gone to emergencies but they turned her down saying they only had an ophthalmologist for in - patients at the hospital. I told her to go to her ophthalmologist the next day at lunch time , to catch the doctor himself on his way to lunch , and bypass the secretary , and ask him what she should do. So my mum wrote a detailed description of her condition and handed it to the doctor the next day . After reading he asked the secretary to secure an appointment sooner . It turned out it was a vitreous hemorrhage and the spot started to get lighter the day after I posted here. Thank you so much to everyone who replied . It is always good to get somebody else's perspective and I am grateful for you taking the time to reply. God Bless. Sophie.

You need to get her to a Retinal Care Specialist. From your explanation she is experiencing a Vitreous Hemorrhage and/or a Retinal tear or detachment. They should be able to see her as soon as possible. She could lose her vision.

I'm with Churchmouse. Go now to an ER associated with a hospital with ophthalmologist.

I would call the 24-hour nurse helpline provided by her clinic or insurance company, describe the situation in detail, and be guided by their advice.

Well. If it were my eye, I'd consider it an emergency. Wouldn't you?

The worst that can happen if you go and it's nothing is that you've wasted a bit of time and money. The worst that can happen if you don't go and it's - God forbid - a detached retina or something ghastly... doesn't bear thinking about. Me, I'd take her now.
