Identifying herpesvirus DNA in corneal grafts

Recent research suggests the need for routine HSV-1 and VZV PCR testing in all explanted corneas regardless of clinical suspicion to detect, treat, and prevent possible recurrence of herpes infection in corneal grafts and support graft survival.

Investigators conducted a cohort study to determine if there is a correlation between intake of nitrate and AMD progression based on previous suggestions that low nitrate levels in the diet may put patients at risk of AMD progression.
