<p dir="ltr">Papilledema is the swelling of the optic disc resulting from increased cranial pressure. The diagnosis of papilledema is important not only to treat pathologies of the eye, but it also can be an important indicator for underlying brain pathology since the subarachnoid space surrounding the optic nerve is contiguous with the brain. Therefore increased pressure from the brain from pathologies such as hydrocephalus can be transmitted to the posterior eye. To study papilledema, a reproducible post hemorrhagic hydrocephalic rat model was used to study the changes of the retina, optic disc and optic nerve when exposed to high intracranial pressure. Multiple changes were noted in the post hemorrhagic hydrocephalic model including decreased thickness of the ganglion cell complex, decreased retinal thickness in the periphery in females, increased retinal thickness close to the optic nerve in males, increased optic disc width and diameter along with a decrease number of retinal ganglion cells. These findings were similar to findings in human patients with papilledema. Therefore, future studies are indicated using the post hemorrhagic hydrocephalic rat model to further understand the mechanism of papilledema progression and the use of possible therapeutics.</p>
