bilateral. Occlusion s/s: paramedian thalamic syndrome. No vision. Visual agnosia. Cant read,
cant see color. Balint syndrome
Balint syndrome? Correct Ans-difficulty in executing eye movements to engage visual targets
(ocular apraxia), an inability to perceive multiple objects at the same time (simultanagnosia), and
inaccuracy in reaching for visual targets (optic ataxia)
