Corneal Transplant: Does Donor Age Matter?

This report looked at the 10-year results of the Cornea Donor Study (CDS), which evaluated the success rate of penetrating keratoplasty (PK) for endothelial disorders, according to donor age.

For this study, 1090 patients underwent PKs. The 10-year success rate was 77% for the 707 corneas from donors who were aged 12-65 years and 71% for the 383 corneas from donors who were aged 66-75 years; this difference was not statistically significant (P= .11). However, when analyzed as a continuous variable, older donor age was associated with lower graft clarity after the first 5 years (P< .001).

The 10-year success was essentially the same (75%) for donors in the middle age group between 34 and 71 years old but was higher (96%) for the 80 donors who were 12-33 years old and lower (62%) for the 130 donors who were 72-75 years old. Because approximately 75% of donors are in the 34- to 71-year-old age group, the study authors concluded that donor age is not an important factor in most of the PKs performed for endothelial disease.

The school started out with 61 students, one associate professor and seven tutors. In 1956, when the school of Arts opened, the two schools merged to form the University of Mashhad. In 1989, the faculties offering Medical Sciences' degrees across the country separated from the Ministry of Culture and Higher Education. New emerging Medical Universities have gone under management of Ministry of Health, Treatment and Medical Education. Thus the original University of Mashhad was divided into two independent universities: "Ferdowsi University of Mashhad" and "Mashhad University of Medical Sciences'. Mashhad University of Medical Sciences operates at present with 8 faculties, 32 hospitals, 179 rural and 147 urban health centers. It covers an enormous area stretching from the north east to the central parts of the country, which makes it the largest university of Medical Sciences providing health care and treatment services. With 597 teaching staff, 1645 MDs with different specialties, 138 dentists, 123 pharmacists and 25, 402 employees, the university provides health care and medical services to the area's large population as well as to over 25 million tourists a year.
