My mother's tumour had been bleeding, and so she was given one dose of radiotherapy to try to stop it. It seems to have worked, and all is fine on that account. (She also has two stents now.) However, she says that since the radiotherapy - a week ago - her eyesight has got worse. Everything seems dark, and it's as if she has sunglasses on indoors. She has to put the room lights on when it is still light. She had also mentioned flashing bright lights in her eyes whilst the radiotherapy was taking place.
Has anyone else experienced anything like this?
