Taking care to correctly diagnose viral anterior uveitis

This issue of Clinical and Experimental Ophthalmology includes a comprehensive review by Chan and Chee on common forms of viral anterior uveitis – with focus on herpes simplex virus (HSV), varicella zoster virus (VZV), cytomegalovirus (CMV) and rubella virus. Treatments are limited for this group of uveitides, and the review appropriately focuses on diagnosis, providing the reader with an exceptionally detailed description of clinical signs, including a discussion of how to differentiate these entities. This review is welcome: over the past two decades, the majority of newly reported or redefined forms of uveitis have been infectious in nature. Both viral and non-viral forms of infectious uveitis are emerging or re-emerging, and for most of the conditions, a range of phenotypes—including anatomical subtypes—may be observed.
