Sun Exposure as a Risk Factor for Nuclear Cataract

  title={Sun Exposure as a Risk Factor for Nuclear Cataract},
  author={Rachel E. Neale and Jennifer L Purdie and Lawrence W Hirst and Ad{\`e}le C. Green},
Background: Cataracts are the leading cause of blindness and visual impairment throughout the world. An association of sun exposure with cortical cataract has been well established, but the association with nuclear cataract remains unclear. Methods: This case-control study was nested within the Nambour (Australia) Trial of Skin Cancer Prevention conducted between 1992 and 1996. We compared 195 cases who had a nuclear opacity of grade 2.0 or greater with 159 controls. Structured questionnaires… 
Ultraviolet radiation and incidence of cataracts in a nationwide US cohort
A modest role is suggested for residence-based ambient UVR andCataract risk among indoor workers in the United States and history of blistering sunburns before and after age 15, but not previous keratinocyte carcinoma diagnosis was associated with both cataract and cataracts surgery.
Cataract frequency and subtypes involved in workers assessed for their solar radiation exposure: a systematic review
The studies confirm the relationship of long‐term occupational solar radiation exposure with cortical cataracts and give new support for nuclear cataract, although no substantial new data were available to support a relation with the posterior subcapsular subtype.
Years of sunlight exposure and cataract: a case-control study in a Mediterranean population
This study does not support an association with cataract and sunlight exposure over adult life, but exploratory analyses suggested a positive association between years of outdoor exposure at younger ages and risk of nuclear cataracts later in life.
Cigarette smoking and duration of sun exposure as risk factor for cataract formation
Overall, cigarette smoking and its duration appear to increase the risk of senile cataract formation.
Comparison of Epidemiological Factors between Patients with Senile Cataract and Controls without Cataract
A positive correlation between the presence of senile cataract and the following factors was observed: electric shock, sunlight exposure during work, head radiography, smoking, ocular trauma, genealogy, high blood pressure and diabetes (p < 0.001).
External factors in the development of cataract
Age and heredity are the most important risk factors associated with the different types of cataract, and increasing age serves as a surrogate for a number of potential external risk factors, the effect of which is cumulative.
Association of cataract and sun exposure in geographically diverse populations of India: The CASE study. First Report of the ICMR-EYE SEE Study Group
Cataract is associated with increasing level of sun exposure, smoking and exposure to indoor kitchen smoke and its association with cataract and subtypes was similar in males and females.
Associations Among Outdoor Time, Skin Tanning, and the Risk of Surgically Treated Cataract for Australians 45 to 65 Years of Age
In this large Australian cohort 45 to 65 years of age, more outdoor time and ease of tanning with sun exposure were associated with a lower incidence of cataract surgery.
Association between ultraviolet radiation exposure dose and cataract in Han people living in China and Taiwan: A cross-sectional study
Increased COUV level among Han people may be a risk factor for the development of nuclear cataracts, PSC, retrodots and ring-shaped cortical cataract.
The Relationship Between Disability-Adjusted Life Years of Cataracts and Ambient Erythemal Ultraviolet Radiation in China
Greater exposure to UVR increases the disease burden of cataracts in the whole population, especially in the elderly and among the agricultural population, and increased with increases in UVR exposure in 31 regions of China.


Effect of ultraviolet radiation on cataract formation.
It is concluded that there is an association between exposure to ultraviolet B radiation and cataract formation, which supports the need for ocular protection from ultraviolet B.
Epidemiologic associations with nuclear, cortical, and posterior subcapsular cataracts.
Data from the 1971-1972 National Health and Nutrition Examination Survey were used to examine the associations between specific cataract types and age, race, sex, number of years spent in school,
Ultraviolet light exposure and lens opacities: the Beaver Dam Eye Study.
Exposure to UVB light may be associated with the severity of cortical opacities in men, but the lack of an association in women, the group more likely to have corticalOpacities, suggests that other factors may be more important in the pathogenesis of lens opacITIES.
Ultraviolet light exposure and risk of posterior subcapsular cataracts.
Investigation of the role of exposure to ultraviolet light in the B range (UV-B) and other potential risk factors for the development of PSC cataracts suggested that UV-B exposure may be an important risk factor for PSCCataracts.
Risk factors for age-related cataracts.
The strength of the association, consistency of studies, coherence, and biologic plausibility all indicate that both systemic and topical steroids are significant risk factors for the formation of posterior subcapsular cataracts.

Findings from the study, combined with previously reported evidence, suggest that associations with educational status, cortisone use, sunlight exposure, and handgrip strength are real.
Epidemiologic associations with cataract in the 1971-1972 National Health and Nutrition Examination Survey.
Cataracts were more common among blacks, diabetics, and rural dwellers, and were positively associated with increasing age, increasing UV-B radiation counts at the site of the examination, and decreasing number of years spent in school.
Risk factors for nuclear opalescence in a longitudinal study. LSC Group. Longitudinal Study of Cataract.
Most risk factors identified by this longitudinal study confirm those found by the original case-control study, and the increased risk of nuclear opacities in whites appears to be a new finding.
Cataract blindness--challenges for the 21st century.
Readingily available surgical services capable of delivering good vision rehabilitation must be acceptable and accessible to all in need, no matter what their circumstances, and to establish and sustain these services requires comprehensive strategies that go beyond a narrow focus on surgical technique.
The Framingham Eye Study. I. Outline and major prevalence findings.
The proportion of adults with poor "best" visual acuity may be much less than has been estimated by the National Health Survey and the proportion with open-angle glaucoma much more than currently suspected on the basis of foreign studies.
