What is one common symptom of ICP related to vision?

  1. Diplopia

  2. Unequal pupils

  3. Floaters

  4. Photophobia

The correct answer is: Unequal pupils

One common symptom of increased intracranial pressure (ICP) related to vision is unequal pupils, often referred to as anisocoria. When ICP rises, it can cause pressure on the optic nerve and surrounding areas, which may lead to a difference in the size of the pupils. This is an important clinical sign, as it can indicate significant neurological compromise and potential herniation of brain structures. While other visual symptoms such as diplopia, floaters, and photophobia can occur in various conditions affecting the eyes or brain, unequal pupils are particularly indicative of ICP as they suggest potential involvement of the pathways that control pupil constriction and dilation, including the brainstem. Recognizing pupil response can be crucial in emergency situations, as it can help caregivers assess the severity of the patient's condition and guide further interventions.
