Tanaka TS, et al. - Researchers assessed medical records of 53 eyes of 53 patients of mean age 68.0±16.4 years to estimate the long-term consequences of penetrating keratoplasty (PKP) for corneal complications of herpes zoster ophthalmicus (HZO). They noticed difficult healing of the ocular surface and glaucoma as the most common complications. They found 31% of eyes requiring one or more additional postoperative procedures, most commonly tarsorrhaphy (18.9%) and amniotic membrane graft (11.3%). No significant advantage of postoperative long-term acyclovir on visual acuity or graft survival was observed. They suggested favorable tectonic and visual results of PKP for the corneal complications of HZO even in eyes with significant preoperative risk factors.
