Final answer:
Swelling related to meningitis can push on the optic nerve, potentially causing loss of vision by increasing the pressure in the optic nerve sheath, impacting blood flow, and nerve signals. In cases like an orbital fracture, careful monitoring of intraocular pressure is required to prevent further eye damage.
Step-by-step explanation:
Meningitis can cause swelling around the optic nerve, leading to vision loss if the swelling increases pressure within the optic nerve sheath. This pressure can impede blood flow and the transmission of nerve impulses, causing visual disturbances. Addressing the underlying cause of meningitis is crucial to reduce the inflammation and prevent further optic nerve damage.
The case of an orbital fracture, like that of Wight Goodman, is different as it involves physical trauma leading to edema and potentially affecting visual acuity if the swelling compresses the optic nerve. Intraocular pressure is tracked to prevent the development of conditions that could further harm the eye, such as glaucoma.
