Inflammatory signs of moderate Graves' ophthalmopathy decreased with peribulbar triamcinolone acetonide injections. The corticosteroid proved to be a potential alternative treatment for optic neuropathy associated with the disorder.

A 46-year-old white man had decreased central vision in his left eye. He reported that the visual loss had been slowly progressive for about 18 months. He had been to his cornea specialist several times during this period for follow-up of his keratoconus.

A higher degree of myopia and hyperopia was associated with larger cup-to-disc ratio in patients with anterior ischemic optic neuropathy. Overall, cup-to-disc ratio in those patients was significantly smaller than in the general population.

The use of statins may induce the development of diplopia, ptosis and ophthalmoplegia, according to a study of reported adverse drug reactions.

More strabismus, refractive errors and vestibular nystagmus were found in patients with the neurofibromatosis 2 genotype than in the normal population, a study found.

The brain reorganizes visual stimuli when patients with macular degeneration refocus to compensate for a loss of central vision.

ATLANTA — A study of temporal artery biopsies performed in Northern California had the largest and most diverse patient population of any similar study done in the United States, a researcher said here.

ATLANTA — Lymphoma is the most common orbital lymphoid tumor and accounts for about 50% of orbital proliferative lymphoid disorders, a physician said here.

Men are more likely than women to report visual disturbances in cases of idiopathic intracranial hypertension. In addition, they may be less likely to report or experience other symptoms of increased intracranial pressure, such as headache.

Jeffrey Chang Vivek Chaturvedi A 27-year-old woman was referred to the New England Eye Center for evaluation of bilateral restricted eye movements, for which the patient characterized as being “in a daze.” She had initially presented to an outside hospital approximately 1 year prior after a syncopal episode characterized by weakness, nausea and vomiting. She recalled that she would often fall over to the right and had extreme dizziness. On further questioning, she reported difficulty with slurred speech, hiccups, tinnitus and dysphagia to both solids and liquids. She denied seizures, headaches, and gastrointestinal or genitourinary complaints. Initial workup revealed an enhancing lesion in the left medulla and cerebellar peduncle (Figure 1). A lumbar puncture was nondiagnostic, and she was started on Keppra (levetiracetam, UCB) and Decadron (dexamethasone, Merck). Over the course of the year, however, she developed progressively worse diplopia with lateral gaze. She also noticed that while watching television, the images would shake.
