Case 4: ZeIss Cirrus 5 Line Raster Scan OD The PIL is slightly fenestrated in the macula area in both eyes. This subtle abnormality is perhaps more obvious when reviewed next to a normal scan above.

Case 4: Octopus 900 Pro G Standard and M Standard OU The central visual field defect, due to the macular pathology in this case, is far better revealed with the M Program than with the G Program. Similarly, the Defect Curves are far more abnormal with the M Program.

Case 4: Octopus 900 Pro M Standard Greyscale OD As noted in case 3, the points within the central 4 degrees are 0.7 degrees apart. If a patient has a central visual field defect, the M program will typically reveal far more abnormalities than the G Program.

Case 4: Octopus 900 Pro G Standard Greyscale OS The same program in the left eye did reveal slightly more reductions in sensitivity with a few more points falling outside the normal range in the Defect Curve.

Case 4: Octopus 900 Pro G Standard Greyscale OD The G Standard 30 degree White/White TOP (Tendency Oriented Perimetry- see previous case)  program revealed only very mild defects.

Case 4: Topcon 3D OCT Fundus Image OU Case 4: A 24 year old white male presented with slow, progressive loss of vision over the past decade. His most recent subjective refraction yielded -9.00 in the right eye and -6.75 in the left eye with VA of 20/100 OD and OS. His fundus appeared

Case 2: Optovue iWellness Exam and Octopus Pro 900 Since no etiology for macro-infarct had yet been uncovered, the patient was re-questioned about several aspects of his general health. He admitted to snoring and gasping, and what his wife believed was sleep apnea, so severe that she often slept in a different room. The
