Progressive multifocal leukoencephalopathy (PML) is a demyelinating disorder of the central nervous system found in immunodeficient patients, most frequently now in those infected with HIV. It may represent the initial manifestation of HIV infection. Since the central visual pathways may be affected, a variety of neuro-ophthalmic signs and symptoms can manifest. We studied the clinical, radiographic and histopathological characteristics of patients with PML. ⋯ The diagnosis of PML should be considered in immunocompromised patients with neuro-ophthalmic findings, particularly those with homonymous hemianopia.

To examine Canadian ophthalmologists' reported practices related to cataract surgery. ⋯ There seems to be limited use of nonessential preoperative ocular testing by Canadian cataract surgeons. Although ECCE remains the most common type of surgery performed, there appears to be a substantial number of surgeons trying phacoemulsification, and this will likely become the predominant technique in the near future. The self-reported practices of Canadian surgeons with relation to preoperative testing and postoperative follow-up appear to be consistent with the Clinical Practice Guideline for cataract surgery set by the US Agency for Health Care Policy and Research. However, variations in the number of postoperative visits and Nd:YAG capsulotomy rates merit further investigation.
