Herpes zoster sine herpete. A potential cause of iridoplegic granulomatous iridocyclitis.
OBJECTIVE
Herpes zoster ophthalmicus (HZO) is a recurrence of varicella zoster virus involving cranial nerve V-1, but does not always have skin manifestations. The objective of this work is to study iridoplegic granulomatous iridocyclitis as an acute, fulminant iridocyclitis that probably is caused by the recurrence of varicella zoster virus without skin eruptions.


METHODS
The author reports 15 cases of iridoplegia granulomatous iridocyclitis with involvement of the anterior uveal tract without known skin eruptions.


RESULTS
All patients have had a clinical course of iridocyclitis closely resembling those cases of herpes zoster with skin eruptions. Nine of the 15 are documented to have had a recurrence of varicella zoster virus with an appropriate rise and fall of systemic titers. The remaining six patients had clinical findings, including loss of accommodation, iridoplegia, and sectoral iris atrophy that were more typical for HZO than other infectious agents.


CONCLUSIONS
Iridoplegic granulomatous iridocyclitis is a newly described, acute, fulminant uveitis probably caused by a herpes virus and most probably by varicella zoster virus. Herpes zoster sine herpete (erupticum) should be suspected as a potential diagnosis in patients with appropriate anterior segment manifestations. Further study is necessary to discern if any of such cases could be caused by herpes simplex.
