Herpes actually very seldom causes complications, and I'm not familiar with liver damage associated with the virus. In rare, rare cases there can be issues with systemic infection, but keep in mind that most people have some type of HSV infection, and for the vast majority of them such things aren't a realistic concern. Of course, do ask your health care provider if you have questions or concerns, and they can tell you if you need to do anything.
Ocular herpes is most often related to an oral herpes infection that activates and takes a funny nerve path that leads to the eye. Here again, this isn't common, as fewer than 5% of those with recurrent oral herpes experience this. There are various approaches to treatment, depending on the specifics of the case, and can include oral antiviral medications and steroidal eyedrops. Severe cases may necessitate surgery; again, this is not common.
Hope this helps.
