Which is more likely to be caused by exudative AMD: Eccentric Fixation or Eccentric Viewing?

• A. Eccentric Fixation
• B. Eccentric Viewing
• C. Paradoxical eccentric fixation
• D. Normal fusion

Answer: (B)

When the central retina is damaged by exudative AMD, a central scotoma forms and sharp foveal vision is lost. To still recognize details, patients learn to use a different part of the retina—the peripheral retina—as their viewing point. This intentional, practiced use of a non-foveal retinal area for fixation and tasks is called eccentric viewing, and it becomes the habitual way to see, often with a stable preferred retinal locus (PRL. Eccentric fixation would imply simply fixing off-center without the patterned, deliberate use of a nonfoveal area to optimize vision. In AMD, the practical adaptation is this strategic eccentric viewing, not just incidental off-center fixation. Normal fusion is unlikely because the central macula is damaged, disrupting the normal binocular integration that relies on matching central images. So, the more likely consequence of exudative AMD is eccentric viewing, as the patient adopts and trains to use a peripheral retinal location to compensate for central vision loss.
