Presentation transcript:

(A) The Goldmann visual field of the patient described in the case vignette clearly shows paracentral visual loss in the right hemifield of both eyes. (A) The Goldmann visual field of the patient described in the case vignette clearly shows paracentral visual loss in the right hemifield of both eyes. The inferotemporal field loss in the right eye corresponds to the inferonasal field loss in the left eye and is fairly congruous. However, the inferonasal field loss in the left eye represents a central area of absolute scotoma surrounded by relative scotoma, whereas the corresponding inferotemporal field defect in the right eye represents an absolute scotoma. This suggests incongruity to these otherwise homonymous defects. There is another lesion in the nasal field of her left eye that corresponds to the region of the blind spot in the right eye. The larger-than-expected blind spot in the right eye suggests that there may be a centrocaecal scotoma (a central field suppression that encroaches upon the blind spot). There is also mild, symmetrical, visual field constriction, most prominent temporally, nasally and superiorly. (B) The clock figure drawn by our patient. The clock face is fairly well constructed but she could not set the time to ‘ten past eleven’. (C) A Navon figure: a larger global letter made up of a different, repeating, smaller letter.
