Conclusions
Preseptal cellulitis is a severe infection of the eye which is commonly
caused by bacterial organisms but can rarely be viral. Physician should
be aware of the various etiologies, as early detection of causative
organism can lead to focused treatment with de-escalation of
antibiotics, along with appropriate use of topical steroids in cases of
viral etiology. A pooled meta-genomic testing with detection of
microbial cell-free DNA in plasma can be a useful test in identifying
the causative organism early in the disease process.
