Staging of Diabetic Retinopathy using TVEP Phase Spectral Periodicity Analysis

Diabetic retinopathy is one of the common complications of diabetes. Unfortunately, in many cases the patient is not aware of any symptoms until it is too late for effective treatment. Thorough analysis of evoked potential response of the retina, optical nerve and optical brain center will pave a way for early diagnosis of diabetic retinopathy and enable prognosis during the treatment process. This paper presents a non-invasive transient visual evoked potential phase spectral components periodicity measure based method to classify diabetic retinopathy subjects
