This is a cross section of the posterior part of the eye, taken with a machine called OCT (optical coherence tomography). The retina layers are nicely displayed in shades of grey. The vitreous, which is the fluid in the back part of the eye, is typically clear and represented as black on an OCT. When the vitreous cells clump together, they can be detected on OCT, and the patient sees “floaters”
If you or someone you know experiences floaters please call your local optometrist to schedule an appointment. If specialty care, treatment or surgery is required, please ask to be referred to one of the physicians at Eyecare Medical Group, 53 Sewall Street, Portland, Maine 04102 at 888-374-2020, or visit Eyecare Medical Group, Google+ or facebook.com/eyecaremedicalgroup.
