Ischemic Optic Neuropathy Secondary to Intravascular Lymphoma.

Background: To describe a case of optic neuropathy associated with intravascular lymphoma (IVL).

Infiltration of the optic chiasm, nerve, and disc by gliomatosis cerebri.

An 18-year-old man with gliomatosis cerebri (GC) developed tumor infiltration of the optic chiasm and right optic nerve including the optic disc. Although papilledema often is seen with GC, tumor invasion of the optic nerve head is observed.

Ocular motor dysfunction in Parry-Romberg syndrome: four cases.

The authors describe four patients with Parry-Romberg syndrome (PRS) who had abnormal eye movements, ptosis, and facial hemiatrophy. There were delays in diagnosis in all cases, often requiring multiple imaging studies, prior to diagnosis of PRS. These cases demonstrate the variable ophthalmic manifestations of PRS, which can lead to difficulty in diagnosis.

Transient visual loss in a 60-year-old man.

A 60-year-old man after 5 years of recurrent episodic amaurosis fugax, always resolving, experienced an incident of visual loss that was permanent. Computed tomography and magnetic resonance imaging were normal. Transesophageal echocardiogram and carotid duplex scan ruled out embolic sources from the heart and neck vessels.
