Here the author continues her ophthalmic narrative, describing the surprising revelation of a long-standing, yet undetected, condition—a visual field “defect.” Discussing the narrative frames of diagnosis, questions of medical error and uncertainty are addressed. The particular challenges of accounting for a retrospective revelation are explored in detail, invoking themes of narratology, communicability, intelligibility, metaphor, and semiotics. In addition, the ways in which metagnosis invokes various stances toward the relationship between narrative and identity are investigated. This chapter offers an introduction to key concepts in illness narratives, narratology, semiotics, and narrative identity theory, discussed in relation to the author’s experience.
