Figure 3. Macular and optic nerve head optical coherence tomography.

This figure shows the thickness of the surface layer of the retina called the NFL, which is the axon of cells that exit the eye through the optic nerve. In this case it reveals no macular edema although significant decrease of NFL thickness is noted, especially at the superior and inferior borders of the right optic disc (decreased thickness of the NFL is seen in the optic nerve diseases in different conditions such as ischemia or glaucoma). Note that you should interpret the thickness of NFL based on the results of both pie charts and line graphs concurrently. Consequently, although a decrease of NFL thickness on the left side is shown in the pie chart, in the line graph the thickness is in normal range in most areas, so the yellow colors of the pie chart may not be correct.

INF: Inferior; ILM: Inner limiting membrane; NAS: Nasal; NFL: Nerve fiber layer; OCT: Optical coherence tomography; OD: Oculus dextrus; OS: Oculus sinister; RNFL: Retinal nerve fiber layer; RPE: Retinal pigment epithelium; SUP: Superior; TEMP: Temporal.
