Which condition is described by blind patients explicit or implicit denial of vision, following blast injury to both eyes with bilateral occipital lobe strokes?

• A. Blast injury to both eyes with bilateral occipital lobe strokes
• B. Agnosia
• C. Prosopagnosia
• D. Palinopsia

Answer: (A)

Denial of vision after bilateral occipital damage is classic cortical blindness with anosognosia, known as Anton’s syndrome. In this condition, the eyes may be structurally intact, but the patient acts as if they cannot see and may even deny or confabulate about blindness. This differs from other visual disorders in that the awareness of vision is specifically impaired despite normal ocular input.

The other options don’t capture this denial phenomenon. Agnosia refers to trouble recognizing objects despite seeing them, with some awareness of vision. Prosopagnosia is a specific inability to recognize faces. Palinopsia is the persistence or recurrence of visual images after the stimulus is gone. The choice that names a blast injury to the eyes with bilateral occipital strokes describes the cause rather than the perceptual denial itself, so it does not describe the described condition of Anton’s syndrome.
