Study design
Various aspects of the study design of the Andhra Pradesh Eye Disease Study (APEDS) have been described previously.3, 4, 5, 6, 7, 8 A brief description of the sampling procedure follows. A multistage sampling procedure was used to select 24 urban clusters and 70 rural clusters from one urban and three rural areas from different parts of the southern Indian state of Andhra Pradesh, with the aim of having a study sample representative of the urban-rural and socioeconomic distribution of the
Results
Of the 11,786 eligible subjects, 10,293 (87.3%) participated in the study from the four areas of APEDS. Of these, 7775 (75.3%) were from the three rural areas, 5439 (52.8%) were females, and 122 (1.2%) were examined at home.
Discussion
The APEDS was a cross-sectional population-based study representative of the population of Andhra Pradesh in which the participants underwent a detailed eye examination. This allows us to comment on low vision for the population at large.
