The visual pathway is as follows

Retinotectal Pathway

1. Retina

2. Superior Colliculus

Retinogeniculostriate Pathway

1. Retina

2. Thalamus (LGN)

3. Primary Visual Cortex

The left Lateral Geniculate Nucleus receives info about the right visual field where the neurons in the LGN project their axon to primary visual cortex. In a person is unable to process right side of the visual field, there is issue in the left LGN of the visual pathway
