Purpuse: To determine the correlation between presbyopia and body mass index. Methods: Cross-sectional study involving 1030 patients with visual acuity of 20/20 emmetropy, aged between 36-40 years, 51-55 years and 60-65 years, excluding patients with positive test cover, anisometropy with convergence insufficiency or high correlation convergence / accommodation. Assessment of body mass index of all patients, Results: Cross-sectional study involving 1030 patients with visual acuity of 20/20 emmetropy, aged between 36-40 years, 51-55 years and 60-65 years, excluding patients with positive cover test, anisometropy with convergence insufficiency or high correlation convergence / accommodation. Assessment of body mass index of all patients Conclusion: As demonstrated by statistical analysis there is a significant correlation between low body weight defined as a body mass index below 18.5 and a lower incidence of presbyopia or delay its onset and progression with age.Keywords: Presbyopia; Low body weight; Body mass index RESUMO Dobras de coroide é considerado o achado fundoscópico mais prevalente nos casos de tumor orbitário. São ondulações no epitélio pigmentado da retina, membrana de Bruch, porção interna da coriocapilar e que, em alguns casos, podem acometer a retina neurossensorial, sendo então chamadas de dobras coriorretinianas. Diversas condições, oculares e sistêmicas, cursam com dobras de coroide e devem ser corretamente investigadas e, caso necessário, prontamente tratadas. Nesta revisão iremos abordar os aspectos gerais das dobras de coroide, enfatizando suas características nos seguintes exames de imagem: Retinografia, autofluorescência, angiofluoresceínografia e tomografia de coerência óptica.

“…Our study suggests that gender is not a risk factor for correctable NVI among younger or older age groups. A recent meta–analysis 14 has suggested that although there may be a weak association between presbyopia and female sex, this is unlikely due to physiologic differences in accommodation because accommodative amplitude does not differ between men and women.…”

Purpose To estimate the prevalence, potential determinants, and proportion of met need for near vision impairment (NVI) correctable with refraction approximately 2 years after initial examination of a multi-country cohort. Design Population-based, prospective cohort study. Participants People aged ≥35 years examined at baseline in semi-rural (Shunyi) and urban (Guangzhou) sites in China; rural sites in Nepal (Kaski), India (Madurai), and Niger (Dosso); a semi-urban site (Durban) in South Africa; and an urban site (Los Angeles) in the United States. Methods Near visual acuity (NVA) with and without current near correction was measured at 40 cm using a logarithm of the minimum angle of resolution near vision tumbling E chart. Participants with uncorrected binocular NVA ≤20/40 were tested with plus sphere lenses to obtain best-corrected binocular NVA. Main Outcome Measures Prevalence of total NVI (defined as uncorrected NVA ≤20/40) and NVI correctable and uncorrectable to >20/40, and current spectacle wearing among those with bilateral NVA ≤20/63 improving to >20/40 with near correction (met need). Results Among 13 671 baseline participants, 10 533 (77.2%) attended the follow-up examination. The prevalence of correctable NVI increased with age from 35 to 50–60 years and then decreased at all sites. Multiple logistic regression modeling suggested that correctable NVI was not associated with gender at any site, whereas more educated persons aged >54 years were associated with a higher prevalence of correctable NVI in Nepal and India. Although near vision spectacles were provided free at baseline, wear among those who could benefit was <40% at all but 2 centers (Guangzhou and Los Angeles). Conclusions Prevalence of correctable NVI is greatest among persons of working age, and rates of correction are low in many settings, suggesting that strategies targeting the workplace may be needed.

Abstract:Purpose: To determine the near vision spectacle coverage and barriers to obtaining near vision correction among adults aged 35 years and older in the Cape Coast Metropolis of Ghana. Methods: A population-based cross-sectional study design was adopted and 500 out of 576 participants aged 35 years and older were examined from 12 randomly selected clusters in Cape Coast, Ghana. All participants underwent a comprehensive eye examination which included: distance and near visual acuities measurements and external and internal ocular health assessments. Distance and near refractions were performed using subjective refraction technique. Information on participants' demographics, near vision correction status, near visual needs and barriers to acquiring near vision correction were obtained through a questionnaire administered as part of the study. Results: The mean age of participants was 52.3±10.3 years of whom 280 (56%) were females and 220 (44%) were males. The near vision spectacle coverage was 25%, 33% "met need" for near vision correction in the presbyopic population, and 64% unmet need in the entire study population. After controlling for other variables, age (5 th and 6 th decades) and educational level were associated with "met need" for near vision correction (OR=2.7 (1.55-4.68), p =0.00, and OR=2.36 (1.18-4.72), p=0.02 respectively). Among those who needed but did not have near vision correction, 64 (26%) did not feel the need for correction, 55 (22%) stated that they were unaware of available interventions, and 53 (21%) found the cost of near vision correction prohibitive. Conclusion: There was a low near vision spectacle coverage in this population which suggests the need for strategies on health education and promotion to address the lack of awareness of spectacle need and cost of services.
