What is a common symptom of SOF syndrome related to vision?

In SOF (Superior Orbital Fissure) syndrome, one of the hallmark symptoms affecting vision is the combination of a dilated pupil and the loss of accommodation. This occurs due to the involvement of the oculomotor nerve (cranial nerve III), which is responsible for pupil constriction and the muscle control needed for accommodation (the eye's ability to change focus). When this nerve is affected, typically due to compression in the superior orbital fissure by a tumor, an aneurysm, or any other mass effect, it can lead to a dilated pupil that does not respond to light and a diminished ability to focus on near objects, indicating a loss of accommodation.

The other symptoms related to vision, such as reduced visual acuity, hemianopia, and photophobia, are less specific or not characteristic of SOF syndrome. Reduced visual acuity can result from various other causes, hemianopia typically indicates issues further along the visual pathway, and photophobia is a more general symptom that may not directly relate to the specific anatomical and neurological implications of SOF syndrome. Therefore, the characteristic findings associated with pupil response and accommodation are key indicators for identifying the effects of SOF syndrome on vision.
