To provide an update on imaging of the brain and orbit for ophthalmologists. ⋯ New imaging techniques for brain and orbit have an increased potential for improving diagnostic yield. Accurate and timely communication with the neuroradiologist can optimize the prescription and interpretation of imaging in ophthalmology.

To elucidate the relationship between anemia and raised intracranial pressure (ICP). ⋯ Anemia may play a role in the occurrence of raised ICP and papilledema. Although only a few cases in the literature support this association, it may be more common than previously thought. Because most patients are not known to be anemic when papilledema is discovered, we suggest that a complete blood count be obtained in patients with IIH, especially in the absence of known associated factors such as obesity or medications or when treatment aimed at lowering ICP fails to improve the patient's symptoms. The underlying mechanisms remain unknown, but cerebral venous thrombosis should be carefully excluded.

To present an evidence-based review of the systemic adverse effects of beta-adrenergic blockers and recommend safety guidelines for use of ophthalmic beta-adrenergic blockers. ⋯ Many commonly presumed adverse beta-adrenergic blocker effects observed via systemic or ocular administration are not supported by published randomized clinical trials. Wide acceptance of such traditionally purported side effects has been largely due to propagation of isolated case reports and short series as well as personal communication felt to reflect expert opinion. Many more patients may be eligible to use these drugs. Obtaining a careful medical history and checking pulse rate and rhythm in the office should identify the vast majority of patients with potential cardiopulmonary contraindications.

To determine whether routine office techniques used to disinfect tonometer prisms and trial contact lenses are sufficient to prevent transmission of ocular infections. ⋯ A safe office environment can be maintained by following current CDC recommendations for disinfection, as well as instituting some additional procedures.
