age-related macular degeneration prevalence rate
Abstract- Objectives: Age-related macular degeneration (AMD) is a leading cause of irreversible blindness in elderly population. The purpose of the present study was to estimate the prevalence and identify risk factors and covariates of AMD in a hospital population of Central India. Finally, although macular degeneration, mainly age-related, was estimated to be the cause of 7% of blindness and 3% visual impairment worldwide, cataract and undercorrection of refractive error represented more than 50% of all cases. Early and late AMD prevalence rates were 3.0% and 0.1%, respectively, among participants. The age-standardized prevalence rates among participants aged 50+ years were 4.7% and 0.2%, respectively. After controlling for age, men had a higher prevalence of early (3.9% vs. 2.3%, odds ratio [OR] 1.7; 95% confidence interval [CI], 1.3-2.2) and late AMD (0.1% vs. 0.03%; OR 3.5; CI, 0.4-33.4) compared with women. were diagnosed with age related macular degeneration in some form (i.e. dry or wet), thereby yielding a crude prevalence rate of 2.31% (95% Confidence Interval 1.95% - 2.66%). Significant associations were found between AMD and Age >60 years (Odds ratio= 2.37, 95% CI 1.49-3.77, p=0.0001), Gender (OR= 1.49, 95% CI 1.03-2.18, p=0.0366), etc. Prevalence of age-related macular degeneration in a rural Chinese population: the Handan Eye Study.

Author information: (1)Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing, China. PURPOSE: To describe the prevalence of age-related degeneration (AMD) in a rural Chinese population and to assess its associations with age, gender, and smoking. DESIGN: Population-based cross-sectional. PARTICIPANTS: Persons aged 30+ years, recruited between October 2006 and October 2007, from Yongnian County, Handan, Hebei Province, China.

As the age of the subjects increased, the prevalence of AMD also increased (Figure 1), the prevalence being almost double in 70-79 years The Lancet Global Health: Most Cited. 1  Global causes of maternal death: A WHO systematic analysis. 2  Global prevalence of age-related macular degeneration and disease burden projection for 2020 and 2040: A systematic review and meta-analysis.

Results: Out of the (n= 4.638) study sample; 107 subjects. were diagnosed with age related macular degeneration in some. form (i.e. dry or wet), thereby yielding a crude prevalence rate of. 2.31% (95% Confidence Interval 1.95% - 2.66%).
The early and late Age-related macular degeneration rates were 3.0 percent and 0.1 percent respectively.
