Case Report: Simultaneous amplification of herpes simplex virus type 2 and Epstein–Barr virus in an immunocompetent host with acute retinal necrosis |
|
Gustavo Ortiz-Morales, Raul E Ruiz-Lozano, Lucas A Garza-Garza, Patricio J Rodriguez-Valdes, Carlos Alvarez-Guzman Pan Am J Ophthalmol 2021, 3:24 (13 July 2021) DOI:10.4103/pajo.pajo_99_21
Acute retinal necrosis (ARN) is an ocular inflammatory disease characterized by panuveitis and retinal vasculitis. Herpes virus is strongly associated with ARN and can often be detected by polymerase chain reaction (PCR) of vitreous samples. The authors report a case of ARN associated with herpes simplex virus-2 (HSV-2) and Epstein–Barr virus (EBV) in an immunocompetent host. A 72-year-old man with a history of herpes zoster ophthalmicus presented with sudden vision loss in the left eye in the setting of hypertensive anterior uveitis and severe vitreous inflammation. ARN was diagnosed and antiviral and steroid treatment was initiated. Vitritis improved 1 week later and foci of retinal necrosis with occlusive vasculitis were observed. Three days later, a rhegmatogenous retinal detachment developed. Pars plana vitrectomy with retinopexy was performed and a vitreous PCR test was positive for both HSV-2 and EBV. Despite retinal reattachment, visual acuity did not improve. Prophylactic antiviral therapy was continued for the fellow eye. The coexistence of more than one virus in the ARN context is exceedingly rare and might be associated with poor visual outcomes.

Case Report: Visual symptoms after a cardiac ablation procedure: A report of three cases  |
|
Catarina M Monteiro, Mafalda S B. Mota, Mário R R. Ramalho, Isabel M C. Prieto Pan Am J Ophthalmol 2021, 3:23 (13 July 2021) DOI:10.4103/pajo.pajo_88_21
The current study reports three cases of both adult and pediatric patients with a history of self-limited episodes of visual symptoms following ablative procedures for cardiac dysrhythmias. Neurological and ophthalmological evaluations were always unremarkable even when performed during the episodes. The visual disturbances subsided spontaneously, and none of the patients developed any kind of permanent visual damage.

Case Report: Clonazepam-induced acute bilateral transient myopia |
|
Singh Swati, Koul Akanksha Pan Am J Ophthalmol 2021, 3:21 (13 July 2021) DOI:10.4103/pajo.pajo_89_21
Clonazepam belongs to the benzodiazepine group of drugs and has a quick onset and prolonged duration of action. It is frequently prescribed for treatment of anxiety disorder and panic attacks. Benzodiazepines are known to induce angle closure glaucoma in susceptible eyes but acute drug induced myopia is reported only with Chlordiazepoxide usage. We report the case of a 45-year-old woman who developed acute bilateral myopia after consumption of clonazepam which resolved completely after drug withdrawal.
