title: [Visual disability incidence among diabetes patients in Olsztyn province in the years 1990-1999].
abstract: The aim of the study was to estimate the incidence of visual disability. Long-term studies on visual disability have been conducted in Olsztyn Province since 1989. A standardized register has comprised 292 patients with diabetes type 1 and 2 whose visual disability resulted from diabetes. Visual disability incidence was expressed by means of a standard rate describing the number of newly diagnosed cases of visual disability per 100,000 population per year. Diabetes related visual disability incidence rate ranged from 2.52/100,000 population in 1990 to 3.08/100,000 population in 1999. For diabetes type 1, visual disability incidence rate was 1.20/100,000 population in 1990 and 1.03/100,000 population in 1999. For diabetes type 2, the rate was 1.33/100,000 population in 1990, increased to 4.66/100,000 population in 1995, and decreased to 2.05/100,000 in 1999. The rate was twice as high among women as among men.
  
  
  CONCLUSIONS
  1. The incidence of visual disability in 1990-1999 was 2.52 to 3.08/100,000 population on average. For type 2 diabetes it was significantly higher than for type 1 diabetes. 2. The monitoring of visual disability is a good indicator of diabetological care.
