PurposeTo assess the contribution of trachoma, cataract and refractive error to visual morbidity among Indigenous adults living in two remote communities of the Northern Territory.Design, Setting And ParticipantsCross-sectional survey of all adults aged 40 and over within a desert and coastal community.Main Outcome MeasuresVisual acuity, clinical signs of trachoma using the simplified WHO grading system and assessment of cataract through a non-dilated pupil.ResultsTwo hundred and sixty individuals over the age of 40 years participated in the study. The prevalence of visual impairment (<6/12) was 17%. The prevalence of blindness (<3/60) was 2%, 40-fold higher than seen in an urban Australian population when adjusted for age. In total, 78% of adults who grew up in a desert community had trachomatous scarring compared with 26% of those who grew up in a coastal community (P < or = 0.001). In the desert community the prevalence of trachomatous trichiasis was 10% and corneal opacity was 6%. No trachomatous trichiasis or corneal opacity was seen in the coastal community.ConclusionsTrachoma, cataract and uncorrected refractive error remain significant contributors to visual morbidity in at least two remote indigenous communities. A wider survey is required to determine if these findings represent a more widespread pattern and existing eye care services may need to be re-assessed to determine the cause of this unmet need.
