Abstract Details

Purpose:

The H70 study is a large population study on 70-year old people in the Gothenburg area. The purpose of the study was to determine the prevalence of lens opacities in 70-year-old persons as well as the prevalence of pseudophakia and to compare with self-reported diagnosis of cataract and previous cataract surgery.

Setting:

Department of Ophthalmology, Sahlgrenska University Hospital, Mölndal, Sweden.

Methods:

Within the H70 study, 1182 70-year old people completed a questionnaire on previous cataract surgery and/or a diagnosis of cataract as reported from their ophthalmologist. A random subset of subjects from this cohort (n=561) were invited to an ophthalmologic examination including lens photography in a biomicroscope. The Lens Opacity Classification System (LOCSIII) was used for classification and grading of cataracts.

Results:

In this cohort of 70-year-olds, the prevalence of self-reported cataract was 23.4% with 14.6% people stating that they had undergone cataract surgery. Upon eye examination, 13.8% were pseudophakic in either eye and 9.6% in both eyes. The proportion of pseudophakic women (either eye) was 17.2% as compared to 9.8% in men (p=0.014). Pseudophakia in both eyes was evident in 12.8% of the women and in 6.1% of the men (p=0.009). Nuclear and posterior subcapsular opacities were slightly more common in women, p=0.034 and 0.010 respectively.

Conclusions:

In this cohort of 70-year-old people, the prevalence of pseudophakia agreed well with that found upon examination. Women have a higher prevalence of lens opacities and previous cataract surgery.
