I got checked out today at a&e this morning as I've been seeing a shadow in my peripheral lower vision and more viable when I turn my head to each side. Its in both eyes so I knew retinal detachment was unlikely as usually its just one eye but I know its a definite symptom so I went straight there just incase. I've also been seeing rainbow halos around lights. I'm only 30 but I know glacouma can happen in younger people. I didn't get seen by an eye doctor but a doctor tested my sight in by getting me to read the letters etc in the eye room and said that was perfect. I told her I don't feel the shadow is blocking my peripheral vision but its there. I told her I have had signs of high blood pressure on my retina in the past. She did peripheral vision tests on me with her fingers and they were OK then she said I can look with this little handheld ophthalmoscope but I don't have anything else so your better going to the options and they can dilate your eyes etc to get a proper look. She had a look and said my retinas were attached. Basically I'm wondering if she had saw anything sinister do you think she would have sent me away to make an eye appointment with the option or would she not have been able to even see the optic nerve or anything with her instrument she had available as that's the main thing I'm panicking about. Any replys or answers would be appreciated.
