Comments and Conclusions • VEPs provide objective assessment of macula, optic nerve and visual pathway function. • VEPs generally correlate well with objective tests of structure such as SD OCT. • Pattern and flash VEPs can be used to assess the prognosis in "amblyopes" and identify those who have an organic disorder causing the

Case 5: Comparing Objective Structure (GCC) & Objective Function (VEP) Objective structure (GCC) and objective function (VEPs) are both abnormal in the RE and confirm an optic neuropathy but do not identify a specific etiology. The VEP also appears delayed in the LE but the GCC appears

Case 5: Diopsys™ Nova-DN OU Visually evoked potentials (VEPs) were obtained with the new Diopsys system, the NOVA (Neuro Optic Vision Assessment). The specific program used was the DN (Diseases of the Optic Nerve) and each testing condition takes only 15 sec or so. Above are VEPs to low and high contrast levels

Case 5: iVue GCC Thickness Patient vs. Normal OU The normal GCC appears as a green donut and in a normal patient, the thickness in the RE is very similar to the thickness in the LE. Similarly, the thickness inferiorly is very similar to the thickness superiorly in normal patients. In our patient,

Case 5: Topcon 3D OCT Fundus Photo OU Case 5: A 60-year-old WM was reevaluated at the request of his optometrist. Best corrected VA has always been 20/20 in the right and left eye. Decades earlier, the optometrist noticed that the patient's right optic disc appeared to be somewhat more pale than his

Case 4: Optovue iWellness Exam Using the iWellness Exam protocol, the GCC appears normal. A review of the 26 retinal sections failed to reveal any abnormality. DIAGNOSIS: The normal VEP suggests that the visual pathway up until Brodmann's Area 17 (or Visual Cortex 1) is intact. Since our patient has some form of
