“…The Proyecto VER (Vision Evaluation and Research) Study 53 found that uncorrected refractive error accounted for 73% of the impaired VA among Mexican American individuals 40 years and older. Similar findings were reported in the United Kingdom, 45 India, 55 and Australia. [56][57][58] Recently, the National Eye Institute estimated the prevalence and cost of correctable VI of the general population and emphasized the importance of correcting VI due to refractive error in improving safety and quality of life.…”

To examine the prevalence and correlates of visual impairment (VI) among US adults with and without diabetes mellitus.Methods: Using National Health and Nutrition Examination Surveys conducted during 1999-2004, we estimated the prevalence of presenting (correctable or uncorrectable), correctable, and uncorrectable VI among Americans 20 years or older with and without diabetes. Data were weighted to make estimates representative of the US civilian noninstitutionalized population. We used multivariate logistic regression to calculate odds ratios and corresponding 95% confidence intervals.Results: Approximately 11.0% of US adults with diabetes had some form of VI (3.8% uncorrectable and 7.2% correctable). Among those without diabetes, 5.9% had some form of VI (1.4% uncorrectable and 4.5% correctable). People with diabetes were more likely to have uncorrectable VI than those without diabetes, even after controlling for selected other factors (PϽ.05). Our findings also suggest a strong association between VI (correctable and uncorrectable) and older age, member of racial/ ethnic minorities, lower income, and lack of health insurance, all independent of diabetes status (P Ͻ.05).Conclusions: Vision loss is more common in people with diabetes than in people without diabetes. Diverse public health strategies are needed to reduce the burden of both correctable and uncorrectable VI.

Purpose: The aim of the study was to determine the pattern of ocular conditions among patients who attended the Salvation Army Eye Clinic at Wiamoase in the Ashanti Region of Ghana in 2016.Method: A retrospective study of all patients attending the Salvation Army eye clinic at Wiamoase in 2016 was done.Results: A total of 1000 folders were used in the study. There were 382 males (38.20%) and 618 females (61.80%) with a male to female ratio of 1:1.6. The mean age was 45.99 years (SD= ± 27.69). The commonest eye disorder encountered was conjunctivitis (39.70%). This was followed by cataract (24.40%), glaucoma (9.70%) and refractive errors (8.90%). 96.72% of cases of cataract and 85.57% of cases of glaucoma occurred in those above 40 years. Of those with refractive error, there were 40.45% with myopia, 34.83% with astigmatism and 24.72% with hyperopia. Conjunctivitis and cataract were significantly higher in females with p values of 0.008 and 0.000 respectively using the chi square test. However, there was no significant difference in the prevalence of glaucoma and refractive errors between males and females with p values of 0.189 and 0.255 respectively. Presbyopia was significantly higher in males with p values of 0.017. Conclusion:Conjunctivitis, cataract, glaucoma and refractive errors were the major ocular conditions seen in this study. Efforts aimed at reducing ocular morbidity should target these conditions.
