A typical mycobacterial infections are frequent, late complications of
human immunodeficiency virus infections and may have a variety of cli
nical manifestations. We describe a patient with end-stage acquired im
mune deficiency syndrome and disseminated atypical mycobacteriosis cau
sed by Mycobacterium avium-intracellulare complex? with prominent iris
nodules as the initial manifestation of a unilateral localized panoph
thalmitis. Acid-fast bacilli were identified cytologically from the ir
is nodule and aqueous aspirations. Topical, intracameral, and systemic
treatments were used, but the infection progressed and enucleation wa
s performed to avoid the impending scleral rupture. Histopathologic st
udies revealed an anterior panophthalmitis, with inferior scleral rupt
ure due to acid-fast bacilli in the eye. Mycobacterium avium-intracell
ulare complex has been described as a cause of endophthalmitis in immu
nocompromised patients but, to our knowledge, this is the first report
of a patient with iris nodules.
