Case 3: Optovue iWelinessExam OU An Optovue iWellnessExam revealed dramatic reduction in the thickness of the GCC. Recall the average value of the GCC thickness in a normal population is approximately 95 microns with a standard deviation of 7.5 microns. The patient's GCC thickness in Case 3 is nearly 4 standard deviations away from
Case 3: Topcon 3D OCT Color Fundus Image OS Note the temporal optic nerve pallor.
Case 3: Topcon 3D OCT Color Fundus Image OD Case 3: A 25-year-old white male presented with a history of optic nerve pallor and peripheral field loss OU. CT and MRI scans were obtained six years earlier and found to be normal. Of interest, his father has similar visual field defects in
Case 2: Optovue iWelinessExam OU In summary: The Optovue iWellnessExam detected loss of the GCC in both eyes but the retinal scans and full retinal thickness appear WNL OU. The patient was fully educated about glaucoma, his need to comply with the eye drop therapy and the importance of the comprehensive systemic work-up.
Case 2: Visual Field Test 24-2 OU The visual fields are profoundly abnormal in each eye with good fixation. Normal/low tension glaucoma sometimes shows a central field loss, due to a reduction in the papillomacula bundle fibers. However, the reduction in the papillomacula bundle thickness is also often due to a secondary non-glaucomatous
Case 2: iVue Cornea Pachymetry Report OU With both a reduced GCC and RNFL glaucoma becomes a likely diagnosis. Hence, corneal pachymetry was obtained with the same system. The corneas measured approximately 440 microns which is about 110 microns thinner than a normal cornea.²
Case 2: iVue Glaucoma Optic Nerve Head Report OU With regards to the parapapillary retinal nerve fiber thickness, the papillomacular bundle (as estimated by the RNFL in the temporal quadrant) is quite thin (48 microns OD and 45 microns OS) and is the most abnormal of the 4 quadrants. This pattern is not typical of
Case 2: iVue GCC Thickness Patient vs. Normal Comparison OU The GCC above is clearly thinner in both of the patient's eyes than in a normal control. The vast majority of normal patients have a symmetrical "green donut" in each eye as shown in the normal control. When the donut appears to
Case 2: Optovue iWellnessExam OU An Optovue iWellnessExam was obtained. The retinal cross sectional scans appear normal but the GCC is abnormal in each eye.
