[PMID: 38971323 DOI: 10.1016/j.ophtha.2024.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 06/18/2024] [Accepted: 07/01/2024] [Indexed: 07/08/2024] Open
Abstract
PURPOSE Prevalence of myopia and vision impairment due to myopic macular degeneration and myopia-related optic neuropathies have markedly increased worldwide. We evaluated whether myopia is associated with other ocular disorders. DESIGN Population-based studies conducted in Russia, China, and India. PARTICIPANTS The Russian Ural Eye and Medical Study (UEMS) and the Beijing Eye Study (BES) included 5899 individuals and 4439 individuals (all aged 40+ years), respectively, and the Central India Eye and Medical Study (CIEMS) consisted of 4711 individuals aged 30+ years. The studies were conducted in rural and urban regions in Bashkortostan/Russia, Nagpur/India, and Beijing/China. METHODS The participants underwent a series of ophthalmological and general medical examinations. MAIN OUTCOME MEASURES Axial length as a surrogate for myopia and prevalence of diabetic retinopathy (DR), age-related macular degeneration (AMD), angle-closure glaucoma (ACG), and open-angle glaucoma (OAG). RESULTS In the UEMS, DR prevalence (odds ratio [OR], 0.73), AMD prevalence (OR, 0.85), and ACG prevalence (OR, 0.72) decreased, and OAG prevalence (OR, 1.65) increased with longer axial length in multivariable analyses. In the CIEMS, lower AMD prevalence (OR, 0.81) and lower ACG prevalence (OR, 0.55), and higher OAG prevalence (OR, 1.45) were associated with longer axial length. Diabetic retinopathy prevalence (0.33%) was too low for statistical analysis in the CIEMS. In the BES, prevalence (OR, 0.64) and 10-year incidence of DR (OR, 0.48) and prevalence (OR, 0.83) and 5-year incidence of AMD (OR, 0.996) decreased, and prevalence (OR, 1.35) and 10-year incidence of OAG (OR, 1.40) increased with longer axial length. In all 3 studies, the association between higher OAG prevalence and longer axial length was nonlinear with a slight increase for the moderate myopia range and a steep increase in the highly myopic range. CONCLUSIONS Myopia is associated with a lower prevalence of DR, AMD, and ACG and a lower incidence of DR and AMD, whereas high myopia more than moderate myopia is associated with a higher prevalence and incidence of OAG. Future studies may assess whether in myopia (in particular, in moderate myopia), the myopia-related advantages, that is, lower prevalence of DR, AMD, and ACG, may outweigh the increased risks for OAG and other myopia-related disorders.

Technological Perception with Rural and Urban Differentiation and Its Influence on the Quality of Life of Older People with Age-Related Macular Degeneration. Eur J Investig Health Psychol Educ 2024; 14:1470-1488. [PMID: 38785595 PMCID: PMC11119705 DOI: 10.3390/ejihpe14050097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 05/12/2024] [Accepted: 05/16/2024] [Indexed: 05/25/2024] Open
Abstract
The past decade has seen a global increase in population age, especially in developed countries, where aging involves visual diseases such as age-related macular degeneration (AMD), which severely affect quality of life (QoL) and mental health, as well as increase isolation and care costs. This study investigated how persons with AMD perceive the impact of technology use on their QoL, focusing on potential disparities between urban and rural contexts in Spain. Using a cross-sectional observational design, data from the 2020 National Statistics Institute's Disability, Personal Autonomy, and Dependency Situations Survey were analyzed, focusing on QoL aspects based on the WHO items of the WHOQOL-100 scale. The results revealed a generally positive perception of technology among participants, with urban residents perceiving technology's positive impact more favorably. Sex discrepancies in technology perception were also observed, as women exhibited a more positive outlook on technology's influence on QoL. The analysis of QoL aspects, such as 'Visibility', 'Learning', 'Mobility', and 'Domestic life', highlighted distinct challenges faced by rural and urban populations, underscoring the importance of context-specific approaches in technology interventions. However, these perceptions were intertwined with comorbidities, which can exacerbate AMD-related issues. Furthermore, this study explored the role of technology in enhancing QoL among older adults with AMD, examining how it influences daily activities and independence, particularly in the context of AMD management. This study concluded that developing more-inclusive policies tailored to the specific needs of persons with AMD, with special attention to environmental and sex differences, is imperative to enhance the positive impact of technology on their QoL.

Abstract
PURPOSE To investigate the prevalence and risk factors of age-related macular degeneration features among pilots of Republic of Korea Air Force. METHODS This retrospective, cross-sectional study was performed with a total of 2781 Republic of Korea Air Force pilots who underwent regular medical examinations between 2020 and 2021. Age-related macular degeneration features were determined and graded by fundus photographs. Risk factors were identified with logistic regression analysis in odds ratio (OR) and 95% confidence interval (CI). RESULTS The prevalence was 12.9% in the Republic of Korea Air Force pilots and 35.2% in those older than 50 years. Pilots with age-related macular degeneration features were positively associated with age (OR: 1.082, CI: 1.067-1.096, P < 0.001), male sex (OR: 0.229, CI: 0.056-0.939, P = 0.041), smoking (OR: 1.027, CI: 1.008-1.047, P = 0.006), flight time (OR: 1.004, CI: 1.003-1.005, P < 0.001), total cholesterol (OR: 1.004, CI: 1.000-1.007, P = 0.033), and low-density lipoprotein (OR: 1.005, CI: 1.001-1.008, P = 0.011). Aircraft type was also identified as a risk factor (OR: 0.617, CI: 0.460-0.827 for carrier, OR: 0.572, CI: 0.348-0.940 for helicopter, P = 0.002), with fighter pilots having a higher risk than carrier and helicopter pilots. The results were similar for pilots older than 50 years. CONCLUSION The prevalence of age-related macular degeneration features in Republic of Korea Air Force pilots was higher than in other general populations studied. Identified risk factors such as flight time and aircraft type suggest potential occupational risk of age-related macular degeneration in aviators.

Abstract
Topic Though lipid and cholesterol dyshomeostasis is thought to contribute to the pathogenesis of age-related macular degeneration (AMD), there is no consensus regarding which elements of systemic lipid homeostasis are perturbed in AMD. In this systematic review and meta-analysis, an update to that performed by Wang et al in 2016, we characterized serum lipoprotein profiles in patients with AMD and its various stages. Clinical Relevance These findings may identify novel therapeutic approaches for AMD, a leading cause of blindness among older adults in the industrialized world. Methods We used MEDLINE, Embase, and Web of Science to identify articles from database inception to May 2022 that reported blood/serum levels of lipid subspecies (triglycerides [TGs], total cholesterol [TC], low-density lipoprotein [LDL], and high-density lipoprotein [HDL]) in patients with AMD compared with controls. We meta-analyzed the data by generating multilevel random-effects models using restricted maximum likelihood estimation. Results Our updated meta-analysis included 56 studies, almost 3 times as many studies as the 2016 meta-analysis with a total of 308 188 participants. There were no significant differences in serum TG, TC, LDL, or HDL between patients with AMD and non-AMD controls. Given significant heterogeneity, we performed subanalyses specifically in patients with early to intermediate nonexudative AMD, advanced nonexudative AMD, and advanced exudative AMD. Compared with non-AMD controls, patients with early to intermediate nonexudative AMD had significantly lower serum TG (standardized mean difference [SMD]: -0.03; 95% confidence interval [95% CI]: -0.06 to -0.01) and higher serum HDL (SMD: 0.07; 95% CI: 0.04-0.11). Patients with advanced exudative AMD had significantly higher serum LDL (SMD: 0.33; 95% CI: 0.04-0.62) compared with non-AMD controls. There were no other significant differences identified. Conclusion We found that there is significant heterogeneity in systemic lipoproteins in patients with AMD compared with non-AMD controls. The specific pattern of lipid dyshomeostasis appeared to be distinct based on AMD stage. These findings highlight both the underlying heterogeneity of AMD as well as the presence of distinct pathophysiological mechanisms involved at different stages or subtypes of AMD and may inform the development of novel therapeutic approaches.

Abstract
Background Despite the well-established findings of a higher incidence of retina-related eye diseases in patients with diabetes, there is less investigation into the causal relationship between diabetes and non-retinal eye conditions, such as age-related cataracts and glaucoma. Methods We performed Mendelian randomization (MR) analysis to examine the causal relationship between type 2 diabetes mellitus (T2DM) and 111 ocular diseases. We employed a set of 184 single nucleotide polymorphisms (SNPs) that reached genome-wide significance as instrumental variables (IVs). The primary analysis utilized the inverse variance-weighted (IVW) method, with MR-Egger and weighted median (WM) methods serving as supplementary analyses. Results The results revealed suggestive positive causal relationships between T2DM and various ocular conditions, including "Senile cataract" (OR= 1.07; 95% CI: 1.03, 1.11; P=7.77×10-4), "Glaucoma" (OR= 1.08; 95% CI: 1.02, 1.13; P=4.81×10-3), and "Disorders of optic nerve and visual pathways" (OR= 1.10; 95% CI: 0.99, 1.23; P=7.01×10-2). Conclusion Our evidence supports a causal relationship between T2DM and specific ocular disorders. This provides a basis for further research on the importance of T2DM management and prevention strategies in maintaining ocular health.

Abstract
PURPOSE To assess the prevalence of reticular pseudodrusen (RPD) and their determinants. METHODS The Population-based Ural Eye and Medical Study conducted in Bashkortostan/Russia included 5899 participants aged 40+ years. Presence of RPDs was assessed on conventional colour fundus photographs, red-free fundus images and optical coherence tomographic images. RESULTS The study included 4914 (83.3%) individuals (mean age: 58.5 ± 10.5 years; range: 40-94 years). Using two age limits (>55 years and 40+ years) for the definitions of RPD and AMD (age-related macular degeneration), RPD prevalence was 186/4914 (3.8%; 95% confidence interval (CI): 3.3, 4.3) and 246/4914 (5.0%, 95% CI: 4.4, 5.6), respectively, and the prevalence of any AMD without RPD was 182/4914 (3.7%: 95% CI: 3.2, 4.2) and 224/4914 (4.6%; 95% CI: 4.0, 5.1) respectively. Within the subgroup of early AMD, intermediate AMD and late AMD, RPD prevalence (age limit: 40+ years) was 55.1% (95% CI: 49.5, 60.8), 42.9% (95% CI: 33.8, 51.9) and 33.3% (95% CI: 16.4, 50.3) respectively. In multivariable analysis, higher RPD prevalence (age limit 40+ years) was associated with higher age (odds ratio (OR): 1.08; 95% CI: 1.07, 1.10; p < 0.001), rural region of habitation (OR: 3.81; 95% CI: 2.76, 5.24; p < 0.001) and lower percentage of lymphocytes on leukocyte counts (OR: 0.95; 95% CI: 0.93, 0.97; p < 0.001). Higher prevalence of any AMD without RPD was associated with urban region (OR: 1.58; 95% CI: 1.18, 2.11; p = 0.002), lower diabetes prevalence (OR: 0.55; 95% CI: 0.33, 0.90; p = 0.02) and shorter axial length (OR: 0.85; 95% CI: 0.74, 0.98; p = 0.03), after adjusting for age. CONCLUSIONS Reticular pseudodrusen (mean prevalence: 3.8% (age limit >55 years); 5.0% (age limit 40+ years)) differs from AMD without RPD in its association with urban region (AMD without RPD: rural region), lower lymphocyte percentage (AMD without RPD: no association) and a lack of associations with axial length (AMD without RPD: shorter axial length) and with diabetes prevalence (AMD without RPD: lower diabetes prevalence).

Abstract
PURPOSE To elucidate the clinical characteristics of eyes with dry age-related macular degeneration (AMD) in Japan. STUDY DESIGN Retrospective. METHODS We performed a nationwide survey of dry AMD. A questionnaire on dry AMD was sent to 3,801 major hospitals and eye clinics nationwide. Whenever both eyes met the diagnostic criteria, only the eye with more advanced geographic atrophy was included. RESULTS In the current survey, 81 patients (81 eyes) with dry AMD were included. Of the 81 patients, 56 (69.1%) were men, and the mean age of the patients was 76.6 ± 8.4 (range, 54-94) years. Twenty-four patients (29.6%) had a history of smoking. The decimal best corrected-visual acuity (BCVA) was equal to or better than 0.7 in 25 eyes (30.9%), but worse than 0.1 in 17 eyes (21.0%). The mean BCVA was 0.62 ± 0.59 in logarithm of the minimum angle of resolution. Lesion size (the greatest linear dimension of the largest geographic atrophy) was ≥ 2 disc diameter in 33 eyes (40.7%) and < 1 disc diameter in 21 eyes (25.9%). Soft drusen was observed in 27 eyes (33.3%), and reticular pseudodrusen was observed in 31 eyes (38.3%). Of the 81 patients, the other eye was diagnosed as dry AMD in 26 eyes (32.1%), neovascular AMD in 16 eyes (19.8%), and intermediate AMD in 18 eyes (22.2%). CONCLUSION Dry AMD in the Japanese population has characteristics of male predominance, older age, high prevalence of reticular pseudodrusen, and high bilaterality.

Abstract
Based on the analysis of published data, the review provides information on the role and mechanisms of angiogenesis in the development of eye diseases. It has been shown that the developing inflammatory process associated with infections or damage to the organ of vision almost always leads to the appearance of newly formed vessels in the avascular cornea. The progression, in particular, of age-related macular degeneration is associated with the immune-mediated development of angiogenesis processes. A key inducer of angiogenesis is vascular endothelial growth factor (VEGF), whose activity can be enhanced by a number of pro-inflammatory cytokines (tumor necrosis factor alpha, TNF-), growth (fibroblast growth factor, FGF) and transforming factors (transforming growth factor beta, TGF- ). In addition, VEGF overproduction is mediated by an imbalance of pro-angiogenic (angiogenin) and anti-angiogenic (angiostatin, vasostatin, endostatin; tissue inhibitors of matrix metalloproteinases) factors. Antiangiogenic activity based on inhibition of vascular endothelial growth factor (VEGF) has been successfully used in the treatment of a number of eye diseases, such as exudative age-related macular degeneration and diabetic macular edema, the pathogenesis of which is based on the growth of newly formed vessels. The review presents information on the main anti-angiogenic drugs for intravitreal administration, used in ophthalmology.

Abstract
IMPORTANCE Advanced age-related macular degeneration (AMD) is a leading cause of blindness in Western countries. Causal, modifiable risk factors need to be identified to develop preventive measures for advanced AMD. OBJECTIVE To assess whether smoking, alcohol consumption, blood pressure, body mass index, and glycemic traits are associated with increased risk of advanced AMD. DESIGN, SETTING, PARTICIPANTS This study used 2-sample mendelian randomization. Genetic instruments composed of variants associated with risk factors at genome-wide significance (P < 5 × 10-8) were obtained from published genome-wide association studies. Summary-level statistics for these instruments were obtained for advanced AMD from the International AMD Genomics Consortium 2016 data set, which consisted of 16 144 individuals with AMD and 17 832 control individuals. Data were analyzed from July 2020 to September 2021. EXPOSURES Smoking initiation, smoking cessation, lifetime smoking, age at smoking initiation, alcoholic drinks per week, body mass index, systolic and diastolic blood pressure, type 2 diabetes, glycated hemoglobin, fasting glucose, and fasting insulin. MAIN OUTCOMES AND MEASURES Advanced AMD and its subtypes, geographic atrophy (GA), and neovascular AMD. RESULTS A 1-SD increase in logodds of genetically predicted smoking initiation was associated with higher risk of advanced AMD (odds ratio [OR], 1.26; 95% CI, 1.13-1.40; P < .001), while a 1-SD increase in logodds of genetically predicted smoking cessation (former vs current smoking) was associated with lower risk of advanced AMD (OR, 0.66; 95% CI, 0.50-0.87; P = .003). Genetically predicted increased lifetime smoking was associated with increased risk of advanced AMD (OR per 1-SD increase in lifetime smoking behavior, 1.32; 95% CI, 1.09-1.59; P = .004). Genetically predicted alcohol consumption was associated with higher risk of GA (OR per 1-SD increase of log-transformed alcoholic drinks per week, 2.70; 95% CI, 1.48-4.94; P = .001). There was insufficient evidence to suggest that genetically predicted blood pressure, body mass index, and glycemic traits were associated with advanced AMD. CONCLUSIONS AND RELEVANCE This study provides genetic evidence that increased alcohol intake may be a causal risk factor for GA. As there are currently no known treatments for GA, this finding has important public health implications. These results also support previous observational studies associating smoking behavior with risk of advanced AMD, thus reinforcing existing public health messages regarding the risk of blindness associated with smoking.

Feldman-Billard S, Dupas B. Eye disorders other than diabetic retinopathy in patients with diabetes. DIABETES & METABOLISM 2021; 47:101279. [PMID: 34534696 DOI: 10.1016/j.diabet.2021.101279] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 08/18/2021] [Accepted: 08/29/2021] [Indexed: 10/20/2022]
Abstract
AIM While diabetic retinopathy is the most specific complication of chronic hyperglycaemia, numerous other ocular conditions also can involve the eyes of people with diabetes. Cataract, glaucoma, age-related macular degeneration, retinal vascular occlusion, and acute ischaemic optic neuropathy combine to impair vision in people with diabetes, especially when they are old. This report provides a critical analysis and an overview of the current knowledge of the main ocular disorders (excluding diabetic retinopathy) and their association in patients with diabetes. METHODS A literature search strategy was conducted for all English-language literature with a systematic review of key references until 2021. RESULTS Patients with diabetes have a high-to-moderate increased risk for most of the usual ocular disorders we reviewed with the exception of age-related macular degeneration. Exposure to chronic hyperglycaemia promotes the development of many eye disorders while acute glucose changes are involved in refractive disorders, diabetic papillopathy and acute cataract. CONCLUSION Diabetes, beyond diabetic retinopathy, increases the risk of numerous eye disorders leading to low vision with implications for daily diabetes management. Even in the absence of clearly demonstrated benefit from glucose control in all eye conditions, achieving good glycaemic control and adherence to diabetes treatment will likely help avoid an additional risk of visual impairment in people with diabetes. In perspective, interesting findings suggesting a preventive effect of metformin use on age-related macular degeneration occurrence justify further studies.
