Herpes simplex viral epithelial keratitis following pars plana vitrectomy

Abstract

Aim:  
To investigate the incidence, and time of onset of Herpes simplex  viral  epithelial  keratitis  (HSVEK)  following  pars plana vitrectomy (PPV). 
Patients  and  methods:  This  is  a  prospective  study  of  all patients  undergoing  pars  plana  vitrectomy  by  one  vitreo- retinal surgeon from January 2014 till January 2019. 
Results: 
865 cases underwent of pars plana vitrectomy, and 8 (0.93%) cases   of   HSVEK   occurred   during   the   first   4   weeks postoperatively. These cases were detected one day (n = 1), one week (n = 6), and one month after surgery (n = 1).  Conclusions: HSVEK is a possible complication after PPV surgeries. Most cases occurred in the first postoperative week.
