The primary consequence of unilateral temporal lobe compression relates to the functions associated with the temporal lobe itself, particularly its role in processing auditory information and various cognitive functions. While the choices presented include various symptoms associated with neurological issues, the most accurate consequence of unilateral compression involves the potential for anisocoria, which is characterized by unequal pupil sizes.

The temporal lobe is home to the hippocampus and areas involved in memory and emotion, but it also plays a critical role in the modulation of autonomic functions through connections to the brainstem. Compression of the temporal lobe can affect the autonomic regulation of the pupils via the oculomotor nerve's pathways. When there is increased pressure on structures in the temporal region, it can disrupt the neural pathways leading to the pupils, resulting in anisocoria.

Visual field loss, altered consciousness, and hearing impairment can occur due to a variety of conditions affecting the brain but are not the primary consequence of unilateral temporal lobe compression specifically. Visual field loss typically relates more to occipital lobe involvement or optic pathway issues. Altered consciousness can arise from widespread cerebral dysfunction, and hearing impairment might be more directly linked to auditory nerve involvement or cortical processing problems rather than direct compression of the temporal lobe itself
