What is primarily responsible for transmitting visual information from the retina to the brain?

• Horizontal cells

• Bipolar cells

• Ganglion cells

• Photoreceptors

What is strabismus?

• A condition where eyes are not aligned properly.

• A type of colour blindness.

• A neurological disorder affecting vision.

• A condition characterized by excessive tearing.

What does the term "receptive field" refer to?

• The overall ocular health of an individual.

• The specific area of the visual field that a particular neuron responds to.

• The range of light frequencies an eye can perceive.

• The area of the retina that contains photoreceptors.

What is prosopagnosia?

• A loss of peripheral vision.

• The inability to recognize faces despite normal vision.

• The inability to see movement.

• The inability to perceive colour.

Where does light falling on the retina primarily trigger phototransduction?

• In the fovea

• In the optic nerve

• In the ganglion cells

• In the choroid

What is characterized by foveal vision?

• It occurs in areas where photoreceptors are absent.

• It is primarily used in dim light conditions.

• It provides low acuity but high peripheral sensitivity.

• It is responsible for colour vision and high detail.

What is the primary function of the dorsal stream in the visual processing pathway?

• Processing spatial awareness and motion.

• Controlling eye movements.

• Regulating pupil response.

• Processing colour and form.

What is the expected outcome of cutting the optic nerve?

• Complete restoration of vision.

• Total loss of peripheral vision in both eyes.

• Total blindness in the affected eye.

• Partial blindness in one eye only.

The optic nerve primarily transmits visual information to which part of the brain?

• Parietal lobe

• Occipital lobe

• Cerebellum

• Temporal lobe

What is astigmatism?

• A condition where the cornea is irregularly shaped, leading to blurred vision.

• A form of colour blindness that affects the retina.

• A condition where there is a complete loss of depth perception.

• A degenerative disease leading to tunnel vision.
