title: Mortality in primary open-angle glaucoma and exfoliative glaucoma.
abstract: OBJECTIVE
  To study mortality among unselected Finnish patients with either primary open-angle glaucoma (POAG) or exfoliative glaucoma (EG) after a minimum follow-up of 7 years after enrollment.
  
  
  METHODS
  A total of 344 patients with POAG and 155 patients with EG had received free medication for the treatment of glaucoma from the Finnish National Social Insurance Institution (FSII). The FSII operates national health insurance, which is compulsory for all Finnish citizens. To be granted free medication, the patient has to file an application with a certificate from an ophthalmologist. If the predefined criteria for glaucoma specified by the Finnish Parliament are met, full reimbursement for glaucoma medications is granted and the patient is listed in the registry of FSII. We reviewed the records of 519 consecutive patients who had been diagnosed with glaucoma and to whom free medication had been granted between June 2004 and December 2005. Patients with acute glaucoma or secondary glaucoma were excluded. Those with open angles were classified into POAG or EG. The quality of the ophthalmologists' records was high. The Finnish Population Registry, a governmental institute, provided information on those patients who had died before January 2013.
  
  
  RESULTS
  At enrollment, the groups with POAG and EG were comparable as regards sex: 66% female with POAG and 68% with EG. The patients with POAG were younger (median 68 years) than those with EG (median 74 years). By January 2013, 59 patients with POAG and 48 with EG had died. At death, the patients with POAG were younger (median 81.8 years) than those with EG (87.9 years). In both groups, the women lived longer than the men, but among patients with POAG, women and men died at a younger age than those with EG.
  
  
  CONCLUSIONS
  As has been reported previously, life expectancy of patients with EG was longer when compared to those with POAG. Higher death rate among patients with EG is explained by higher median age at baseline.
