WebNational Center for Biotechnology Information WebIn photography, angle of view (AOV) describes the angular extent of a given scene that is imaged by a camera.It is used interchangeably with the more general term field of view.. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image.Typically the image circle produced by a lens is large …
WebVisual field loss is progressing despite normal IOP or IOP that’s under control. Severity of cupping doesn’t match the visual field defect. The OCT of the optic nerve and macula does not correlate with the visual fields. The visual fields or macular ganglion cell OCT have a vertical feel to them (homonymous pattern/ bitemporal/junctional). WebPatients with NTG or primary open-angle glaucoma (POAG) present with open angles on gonioscopy, cupping of the optic nerve head and visual field loss. However, NTG has several distinguishing features. As the name implies, NTG patients have a higher propensity for optic nerve damage at relatively low levels of IOP.
