However, the role of EVs in Ocular toxoplasmosis remains unclear. Aims: The goal of this study was to identify and characterize the concentration and size of EVs in the aqueous humor (AH) and plasma of patients with ocular toxoplasmosis (OT) compared to other types of uveitis (OTU) and cataract. Settings and Design: AH and plasma were collected from six patients with active OT, six patients with OTU, and six patients with cataract. All patients were also assessed clinically. Subjects and Methods: EVs were isolated using the membrane affinity column method. Nanoparticle Tracking Analysis (NTA) was performed to determine the size and concentration of EVs. Statistical Analysis Used: The ANOVA test was used to determine statistical difference. P < 0.05 was considered statistically significant. Results: EV was present in the AH of different types of uveitis as well as in patients with cataract. The concentration of EV in AH was significantly lower in OT and OTU compared to cataract (P = 0.03). However, in the plasma, all groups presented a similar concentration of EV. The size of EV was the same in the AH and plasma among the three groups. Conclusion: This initial study successfully identified and characterized EVs in the AH and plasma from patients with OT as well as OTU and cataract. Further studies are necessary to better understand the role of EVs in different ocular pathologies.","PeriodicalId":378703,"journal":{"name":"The Pan-American Journal of Ophthalmology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121303309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":378703,"journal":{"name":"The Pan-American Journal of Ophthalmology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134484332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
