Abstract
Visual impairment has an important economic weight on our society; in addition to this considerable cost, loss of vision imposes physical, financial and quality of life limitations. Preventing visual impairment is not only a social duty but also an economically convenient activity for the national health system.
On the basis of this concept, a visual impairment disability campaign was carried out in the ASL CN1 (Southern Piedmont Region) taking into account the guidelines recommended by the WHO (1968 screening guidelines but still applicable) in the most disadvantaged territories of the cross-border and rural area, where people have more difficulties to reach territorial services or hospital.
Patients who tested positive for the screening were taken over by the local network for a second-level visit and subsequent follow-up based on the pathology found. In this frame, visual screening represents a promising health policy as it can identify visual disability at an early stage. Through the health information systems (hospital discharge, access to the emergency department and exemptions for pathology), the geographical distribution and demographic characteristics of the subjects with visual disability were described in the ASL CN1 area. The level of detail has reached granularity at the single municipality and single age level.
For the year 2018 among 416.000 residents in ASL CN1, about 4.000 visual impaired subjects were identified (3.188 on the basis of the presence of an exemption for glaucoma, 542 from hospital discharge and 535 at the emergency department). Assessing mortality in this subgroup, the mean age at death is slightly higher than that of general population (82,42 vs 81,39 years respectively). This can be suggestive of an efficient handling the local population with visual disability. The developed indicators can be extended to other periods and new areas.
