Q.1 Ans D The term “papilledema” describes optic disc swelling resulting from increased intracranial pressure. Causes of papilledema include intracranial tumors, idiopathic intracranial hypertension (pseudotumor cerebri), subarachnoid hemorrhage, subdural hematoma, and intracranial inflammation. Optic disc edema may also occur from many conditions other than papilledema, including central retinal artery or vein occlusion, congenital structural anomalies and optic neuritis, and anterior ischemic optic neuropathy.

Q.2 Ans A, B, and D.  Signs of optic disc swelling include elevation and blurring of the disc margins, visual field loss, and eventually optic disc atrophy. Cupping is not classically associated with disc swelling.

Q.3 Ans E. These patients may demonstrate symptoms of visual loss, headache, nausea, vomiting, pain on ocular motility, decreased color vision, constriction of the visual field, and diplopia. Optic disc edema arises from the blockage of retrograde and orthograde axoplasmic transport in the optic nerve.

Q.4 Ans. C. In the acute stage, papilledema leads to enlargement of the blind spot, which is the most common and often the only visual field change.  The papillomacular bundle and thus central visual acuity is spared until later stages of the disease. Central scotomaand  cecocentral scotoma is in optic neuritis and toxic optic neuropathy. Baring of blind spot is an early, non-specific visual field change, without much diagnostic value in glaucoma.
