Careful and ongoing observation of IOP, especially in the first year after PK, is recommended for patients after penetrating keratoplasty and prompt treatment of IOP elevation when indicated. Early filtering surgery with a better outcome than other surgery procedures should be preferred if medical treatment is not sufficient. Despite anti-glaucoma therapy, good visual outcome can remain beyond expectations despite a clear graft. While there is a potential option for graft exchange, damage to the optic nerve from end-stage glaucoma leads immutably to visual loss.
Graft survival rate and functional outcome after postoperative antiviral and immunosuppressive treatment in cases of penetrating keratoplasties after herpetic keratitis are comparable with results of normal-risk keratoplasties, despite existing high risks for immune rejections or herpetic recurrences.
The final consent rate was only 6 % out of all potential donors. Organisational failure was only 16 % in contrast to 60 % refusal due to causes relating to medical staff and relatives. Therefore, further education of physicians and the public is needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
