Survival of elderly ophthalmic out-patients

Elderly ophthalmic out-patients that had visited an eye-clinic were searched in a population register 7 years later. Observed numbers of survivors were compared with those expected according to appropriate life tables. Most observed numbers of survivors came close to the expected ones. Patients, aged more than 80 years when visiting the eye-clinic, had, however, a consistently increased survival rate. Glaucoma patients, less than 80 years old, had a slightly (not significantly) lower survival rate than expected.
