Frosted branch angiitis secondary to herpes simplex virus infection progressing to acute retinal necrosis.
OBJECTIVE
To describe a case of frosted branch angiitis secondary to herpes simplex virus type 2 infection that progressed to acute retinal necrosis.


METHODS
The medical records and clinical photographs were reviewed for a patient with frosted branch angiitis that progressed to acute retinal necrosis.


RESULTS
The patient rapidly developed acute retinal necrosis followed by rhegmatogenous retinal detachment. Polymerase chain reaction analysis of the vitreous was positive for herpes simplex virus type 2.


CONCLUSIONS
Frosted branch angiitis is a clinical sign that may represent active viral disease capable of progressing to acute retinal necrosis.
