Case 5: Optovue iWellness Exam OU A 69-year-old white male is HIV+ and has a family history of glaucoma. Goldmann IOPs were 16mmHg OD and 17mmHg OS. Above is the iWellness Exam OU. Note the GCC thinning OS inferior temporal to the fovea.

Case 4: Comparison of GCC and Visual Fields Both the GCC and visual fields appear normal OD. The GCC OS is profoundly attenuated and corresponds to the large decrease in sensitivity on the 24-2 visual fields OS.

Case 4: Optovue iWellness Exam OU A 66-year-old black female who was diagnosed with open angle glaucoma OS a year earlier. Untreated Goldmann IOPS were 18 OD and 38 OS. BCVA was 20/25 OD, 20/25 OS. Note the extremely thin GCC OS only.

Case 3: Comparison of GCC & VF The GCC in the OD is thinnest inferior temporal to the fovea and corresponds to the superior nasal field loss on the 10-2 visual field. In contrast, the GCC OS appears normal and corresponds to a normal 24-2 visual field. In patients with unreliable visual fields, the GCC

Case 3: Optovue iWellness Exam OU A 69-year-old Hispanic female presented with glaucoma (under treatment) in the right eye. GDx NFI 65 OD and 27 OS. Goldmann IOPs were 14mmHg OD and 13mmHg OS. BCVA OD 20/20-3, OS 20/20-3. The GCC is reduced in the OD by 30 um when compared to the OS.

Case 2: GCC Map VS. Maia OD and OS Note that most GCC loss is inferior nasal to the fovea on GCC Map. Maia microperimetry corresponds to the loss in GCC OD. The left eye has a normal GCC Map as well as a normal Maia microperimetry.Diagnosis:Most likely a congenital non-progressive optic anomaly. Careful
