Question regarding retinal detachment. What is it and what can I do about it?

Get evaluated. When the retinal layer peels away from the eye wall (like wall paper), it is detached. When the retina separates like this vision is impaired. This is caused usually by a hole or tear in the retina. Symptoms of an rd are painless vision loss, flashing lights, and floaters. You should immediately seek an evaluation from an ophthalmologist for diagnosis and treatment.
Retina off position. The retina coats the back of the eye and is the film that receives light so you can see. It rests upon a vascular tissue which keeps it healthy (the choroid). A detachment is when these two layers separate - from trauma, anatomical changes, diabetes, etc. It needs rapid repair by a retinal surgeon ophthalmologist. If caught early, the results can be good.
