Background
A pilot study was conducted to evaluate the therapeutic results of intravitreal ganciclovir injection as a loading dose with
or without the following oral valganciclovir for the treatment of cytomegalovirus (CMV) anterior uveitis in immunocompetent
patients.
Methods
Six consecutive patients in whom active CMV anterior uveitis was detected by polymerase chain reaction assay of the aqueous
humor were enrolled between January 2006 and December 2008. These patients received an intravitreal injection of ganciclovir
(2 mg/0.05 ml) as a loading dose. Subsequent use of oral valganciclovir (900 mg twice a day) was determined according to the
severity of the post-injection aqueous inflammation. Immune status and anterior chamber reaction of individual patients, visual
acuity, intraocular pressure (IOP) at study entry, and follow-up intervals were examined.
Results
The mean patient-month follow-up period after intravitreal injection was 14.7 months (range, 12–22 months). Two patients received
only the intravitreal ganciclovir injection once and four patients had received the following oral valganciclovir for average
2.3 months (range, 1–4 months). With this treatment strategy, the best-corrected visual acuity of the patients improved or
stabilized; the IOP and the inflammation of anterior chamber of the patients were well controlled at all time points and there
were no treatment-associated complications by the end of follow-up.
Conclusions
In patients with CMV anterior uveitis, intravitreal ganciclovir injection as a loading dose with or without the following
oral valganciclovir can control the inflammation and IOP well.
