Diabetic
Retinopathy and Macular Edema
Diabetic retinopathy occurs when the blood vessels that nourish the retina deteriorate. As they deteriorate, portions of the blood vessels can leak fluid into the retinal tissue. This leakage may also cause swelling in the macula known as macular edema. The iScan test uses 3-D imaging to accurately stage both proliferative diabetic retinopathy and macular edema. |
