Authors examined the potential risk factors of major and subthreshold depression among elderly persons seeking rehabilitation for age-related vision impairment.
Participants (N=584), age 65 and older, with a recent vision loss, were new applicants for rehabilitation services. Subthreshold depression was defined as a depressive syndrome not meeting criteria for a current major depression (i.e., minor depression, major depression in partial remission, dysthymia) or significant depressive symptomatology.
Seven percent of respondents had a current major depression, and 26.9% met the criteria for a subthreshold depression. Poorer self-rated health, lower perceived adequacy of social support, decreased feelings of self-efficacy, and a past history of depression increased the odds of both a subthreshold and major depression, versus no depression, but greater functional disability and experiencing a negative life event were significant only for a subthreshold depression. Only a history of past depression was significant in increasing the odds of having a major versus a subthreshold depression.
Results highlight similarities in characteristics of, and risk factors for, subthreshold and major depression. Future research is needed to better understand both the trajectory and treatment of subthreshold depression, relative to major depressive disorders.

- "Depending on the population characteristics and the questionnaires used, the prevalence of depressive symptoms is reported to range from 14 to 44% in visually impaired persons in general populations, in outpatient low-vision clinics and in populations with specific eye diseases (Rovner et al. 2002; Horowitz et al. 2005; Evans et al. 2007; Huang et al. 2010; Rees et al. 2010; Kempen & Zijlstra 2014; van der Aa et al. 2015). That these percentages are high is confirmed by data from a systematic review in which prevalence rates of depressive symptoms in general older populations were shown to fluctuate around 10–15% (Beekman et al. 1999).

Although the prevalence of depression in visually impaired older persons is high, the association between vision loss and depression seems to be influenced by factors other than visual impairment. In this study, the role of vision loss, functional limitations and social network characteristics in relation to depressive symptoms was investigated.
Cross-sectional data (N = 1237) from the Longitudinal Aging Study Amsterdam were used to investigate the prevalence of depression (Center of Epidemiological Studies-Depression scale) within subgroups with increasing vision loss. In linear regression models, functional limitations and social network characteristics were examined as possible mediators in the association between vision loss and depression. Having a partner was considered to be a potential moderator.
Although a significant linear trend was found in the presence of depressive symptoms with 14% in normally sighted, 23% in mild and 37% in severe vision loss (χ(2) (1) = 14.9; p < 0.001), vision loss was not an independent determinant of depression. Mediators were functional limitations (p < 0.001) and social network size (p = 0.009). No interaction with partner status was found.
In the presence of depression, a trend was found with increasing severity of vision loss, indicating the need for more attention in (mental) health care and low-vision rehabilitation. In the general older population, vision loss was not an independent determinant of depression but was mediated by functional limitations and social network size. Rather than receiving actual social support, the idea of having a social network to rely on when needed seemed to be associated with lower levels of depression.

- "With regard to mental health, our results show a clear association between visual impairment and depression. Although visual impairment and depression have been associated in working age adults , there is controversy on this topic in older adults [2, 22, 24, 25, 67, 68]. Variability in the studies arises with regard to the type of visual assessment used, including objective visual acuity, medical-record review, presence of age-related eye-disease or vision-loss severity with functional screening.

In the context of population aging, visual impairment has emerged as a growing concern in public health. However, there is a need for further research into the relationship between visual impairment and chronic medical conditions in the elderly. The aim of our study was to examine the relationship between visual impairment and three main types of co-morbidity: chronic physical conditions (both at an independent and additive level), mental health and cognitive functioning.
Data were collected from the COURAGE in Europe project, a cross-sectional study. A total of 4,583 participants from Spain were included. Diagnosis of chronic medical conditions included self-reported medical diagnosis and symptomatic algorithms. Depression and anxiety were assessed using CIDI algorithms. Visual assessment included objective distance/near visual acuity and subjective visual performance. Descriptive analyses included the whole sample (n = 4,583). Statistical analyses included participants aged over 50 years (n = 3,625; mean age = 66.45 years) since they have a significant prevalence of chronic conditions and visual impairment. Crude and adjusted binary logistic regressions were performed to identify independent associations between visual impairment and chronic medical conditions, physical multimorbidity and mental conditions. Covariates included age, gender, marital status, education level, employment status and urbanicity.
The number of chronic physical conditions was found to be associated with poorer results in both distance and near visual acuity [OR 1.75 (CI 1.38-2.23); OR 1.69 (CI 1.27-2.24)]. At an independent level, arthritis, stroke and diabetes were associated with poorer distance visual acuity results after adjusting for covariates [OR 1.79 (CI 1.46-2.21); OR 1.59 (CI 1.05-2.42); OR 1.27 (1.01-1.60)]. Only stroke was associated with near visual impairment [OR 3.01 (CI 1.86-4.87)]. With regard to mental health, poor subjective visual acuity was associated with depression [OR 1.61 (CI 1.14-2.27); OR 1.48 (CI 1.03-2.13)]. Both objective and subjective poor distance and near visual acuity were associated with worse cognitive functioning.
Arthritis, stroke and the co-occurrence of various chronic physical diseases are associated with higher prevalence of visual impairment. Visual impairment is associated with higher prevalence of depression and poorer cognitive function results. There is a need to implement patient-centered care involving special visual assessment in these cases.

ABSTRACT: Purpose. To evaluate association between erectile dysfunction (ED) and neovascular age-related macular degeneration (AMD). Methods. 195 men enrolled in this cross-sectional study. 90 of them had neovascular AMD and 105 of them were healthy volunteers. The International Index of Erectile Function (IIEF) questionnaire's erectile function (EF) domain was used to assess ED. The patients in the study and control groups were statistically compared according to visual acuity, EF score, and body mass index. Results. The mean ages were 62 (54.5-73) and 60 (54-68), in the neovascular AMD and control groups, respectively. The total EF scores were 9 (6-16) in neovascular AMD and 18 (9.5-27) in control group. The results of IIEF questionnaire on neovascular AMD patients revealed that 85 men (94.4%) had some degree of ED, whereas 68 men (64.8%) had some degree of ED on control group. Patients with neovascular AMD had a significantly higher incidence of ED than control patients (P < 0.01). There was a significant association between ED and neovascular AMD (P < 0.01). Conclusions. Our results suggested that neovascular AMD has a high association with ED.
