title: [Analysis of the aqueous humor in keratoplasty patients with keratitis. Initial results].
abstract: OBJECTIVE
  Herpetic keratitis is a common indication for corneal transplantation. In this patient group especially, there is a relatively high risk of graft failure, partly because of viral recurrence. It can be difficult to clinically distinguish stromal herpetic recurrence from early endothelial allograft rejection. Also a perioperative observation of viral activity seems advisable because of therapeutic consequences. For these reasons we use aqueous humor analysis in certain corneal transplant patients to determine intraocular antibody production. The aim of this study was to evaluate the diagnostic value of such an analysis of aqueous humor.
  
  
  METHODS
  A total of 28 samples of aqueous humor were obtained from 24 eyes and all samples were tested for antibodies against herpes simplex virus (HSV), most samples (26/28) were tested for antibodies against varizella zoster virus (VZV) and some samples (6/28) for antibodies against cytomegalovirus. We used a modified micro-ELISA technique to detect intraocular IgG production.
  
  
  RESULTS
  In 14 samples (50%) we found antibodies against HSV, in 7 samples (25%) against HSV and VZV, in 1 sample (3.6%) against VZV and 6 samples (21.4%) were negative for all antibodies tested.
  
  
  CONCLUSIONS
  The results of aqueous humor analysis led to a specific local or systemic antiviral therapy perioperatively or in the case of postoperative recurrence of herpetic keratitis in most patients. Some patients could be spared long-term treatment with antiviral agents because of negative results in the aqueous humor analysis.
