Purpose: To describe the rare entity of concurrent herpetic acute retinal necrosis (ARN) and orbital inflammation. Observations: Two cases of ARN with simultaneous orbital inflammation are described. A 40-year old male presented with a painful left eye and hand motion visual acuity (VA). Both panuveitis and orbital inflammation with involvement of the sclera and optic nerve were observed. He was initially treated with oral steroid therapy, after which the orbital inflammation improved but the panuveitis remained. A diagnostic anterior chamber paracentesis was positive for HSV-2 by PCR. He was started on systemic antivirals, but ultimately developed a retinal detachment. The second patient was an 18-year old female with hand motion VA in the left eye. Panuveitis and severe conjunctival chemosis were observed. MRI demonstrated dacryoadenitis with preseptal inflammation. The patient was initially started on oral steroid therapy, which alleviated the orbital inflammation but not the intraocular inflammation. An anterior chamber diagnostic paracentesis was positive for HSV-1, after which the patient underwent vitrectomy for a retinal detachment. The patient was started on systemic antiviral therapy. Conclusions and Importance: Herpetic disease should remain on the differential for cases of concurrent intraocular and orbital inflammation. Early recognition of this process may help prevent severe vision loss. It is important to recognize that orbital inflammation secondary to herpetic disease may be diverse in its presentation.
