Organizational Learning from Performance Feedback: A Behavioral Perspective on Innovation and Change

Isolated herpes simplex affecting the lid margin can be distinguished from herpes simplex involving the entire eyelid by characteristic features. The typical intermarginal form of herpes-simplex-blepharitis presents itself as an erosion of about 3 mm in length which may be well discerned in detail after fluorescein staining. The skin adjecent to the lesion may also exhibit superficial ulceration, possibly being covered by crusts. The affected portion of the lid shows localized and moderate swelling as well as pain upon pressure. Injection of the bulbar conjunctiva will characteristically be noted mainly in the area opposing the lid lesion. The regional lymph nodes are enlarged, and possibly tender upon palpation. Local medication with anti-viral ophthalmic ointment is effective within a few days.
