Concurrent acute retinal necrosis and orbital inflammation: Report of 2 cases.

ABSTRACT:

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.

Project description:Background Patients with coronavirus disease 2019 (COVID-19) occasionally develop ocular complications. We report a case of acute retinal necrosis (ARN) caused by Epstein–Barr Virus (EBV) that developed in a patient who had severe acute respiratory syndrome due to SARS-CoV-2 infection. Case presentation A 68-year-old woman complained of floaters and blurred vision in her right eye as she was receiving systemic prednisolone for COVID-19 pneumonia under isolation in our hospital. The patient visited an ophthalmologist following her discharge from the hospital and after the 2 weeks of isolation had ended. At the initial examination, her best-corrected visual acuity (BCVA) was 20/100 in the right eye, and the eye showed moderate anterior segment inflammation and vitreous opacities. Treatment was initiated with topical 0.1% betamethasone and 1.5% levofloxacin. After 1 month, the inflammation in the right eye decreased and her BCVA improved to 20/40. However, on day 48 from her initial visit, the inflammation in her right eye worsened and her BCVA decreased to 20/2000 by day 80. Pars plana vitrectomy with silicone oil tamponade was performed to remove the vitreous opacities, and expanded white exudates peripherally and retinal vessels with white sheathing suggestive of acute retinal necrosis (ARN) were seen intraoperatively. Analysis of the vitreous sample revealed EBV positivity on polymerase chain reaction. The patient was diagnosed with EBV-associated ARN and treated with systemic steroids and valaciclovir. The ocular inflammation gradually decreased, and she was discharged from the hospital. However, a week later, the inflammation in the right eye markedly worsened. Despite another course of steroids, the inflammation worsened, resulting in total retinal detachment and absolute glaucoma. Because of the severe pain, the right eye was enucleated. Conclusions Clinicians should be aware that COVID-19 and immunosuppressive treatment can reactivate EBV in the eye.
