Zhang Q, Jiang Y, Deng C, Wang J. Effects and potential mechanisms of exercise and physical activity on eye health and ocular diseases. Front Med (Lausanne) 2024; 11:1353624. [PMID: 38585147 PMCID: PMC10995365 DOI: 10.3389/fmed.2024.1353624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 03/12/2024] [Indexed: 04/09/2024] Open
Abstract
In the field of eye health, the profound impact of exercise and physical activity on various ocular diseases has become a focal point of attention. This review summarizes and elucidates the positive effects of exercise and physical activities on common ocular diseases, including dry eye disease (DED), cataracts, myopia, glaucoma, diabetic retinopathy (DR), and age-related macular degeneration (AMD). It also catalogues and offers exercise recommendations based on the varying impacts that different types and intensities of physical activities may have on specific eye conditions. Beyond correlations, this review also compiles potential mechanisms through which exercise and physical activity beneficially affect eye health. From mitigating ocular oxidative stress and inflammatory responses, reducing intraocular pressure, enhancing mitochondrial function, to promoting ocular blood circulation and the release of protective factors, the complex biological effects triggered by exercise and physical activities reveal their substantial potential in preventing and even assisting in the treatment of ocular diseases. This review aims not only to foster awareness and appreciation for how exercise and physical activity can improve eye health but also to serve as a catalyst for further exploration into the specific mechanisms and key targets through which exercise impacts ocular health. Such inquiries are crucial for advancing innovative strategies for the treatment of eye diseases, thereby holding significant implications for the development of new therapeutic approaches.

Abstract
PURPOSE To evaluate the effect of glaucoma on vision-related quality of life (VRQoL), lifestyle, physical factors and socioeconomic status in a 70-year-old population in Gothenburg, Sweden. METHODS Responses to questionnaires (N = 1182) between groups with and without self-reported glaucoma were analysed. Questionnaires included National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25), Short-Form Health Survey (SF-36), physical activity, socioeconomics, alcohol and tobacco consumption. Balance test and body mass index were also included. About half of the participants were randomized to ophthalmic examination (N = 560), variables were analysed separately according to known and confirmed glaucoma, ocular hypertension and/or cases of previously unknown glaucoma. RESULTS Both conventional and Rasch analysis of the NEI VFQ-25 showed that VRQoL was lower for individuals self-reporting glaucoma (p = 0.003/p = 0.024). Regarding general QoL, the participants did not differ apart from people self-reporting glaucoma reported worse general health (p = 0.01). Using logistic regression with lower VRQoL as the dependent variable glaucoma was not a significant predictor of poor VRQoL, odds ratio (OR) 1.83 (95% confidence interval (CI) 0.76-4.39, p = 0.18). Low household income was associated with lower VRQoL (OR 1.63, 95% CI 1.14-2.33, p = 0.01). Socioeconomics, physical activity and lifestyle factors were comparable between the groups (N = 915). Among participants who underwent ophthalmic examination no significant differences were found between glaucoma cases and non-glaucoma cases in relation to VRQoL (N = 560). CONCLUSIONS Patients with self-reported glaucoma assessed a lower VRQoL but not lower general quality of life. Poorer household income was associated with worse VRQoL. General health was reported low in the glaucoma population but lifestyle or physical factors did not diverge.

Res Sports Med 2024; 32:86-97. [PMID: 35608210 DOI: 10.1080/15438627.2022.2079987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Accepted: 05/16/2022] [Indexed: 10/18/2022]
Abstract
This study aimed to determine the influence of physical fitness level and sex on intraocular pressure (IOP) during the low-intensity aerobic exercise. Forty-four participants (twenty-two men) cycled 30 minutes at low intensity (10% of the maximal power). Maximal power was determined by asking participants to perform maximal sprints of 6 seconds against 3-4 different resistances separated by 3 minutes of rest. The IOP was measured on 9 occasions (1) prior to the warm-up, (2) after the warm-up, (3-7) every 6 minutes during the low-intensity cycling task, and (8-9) 5 and 10 minutes after the cycling task. Low-intensity aerobic exercise had a lowering effect on IOP, being the beneficial effect more accentuated and prolonged in the High-fit group (IOP reduction compared to baseline lasted 30 minutes) than in the Low-fit group (IOP was only reduced at 6 minutes of exercise compared to baseline). Participants´ sex had no effect on the IOP behaviour at any time point (p = 0.453). These findings indicate that individuals who need to reduce IOP levels (i.e., glaucoma patients or those at risk) should increase or maintain a high fitness level to benefit more from the IOP lowering effect during low-intensity aerobic exercises.

Therapeutic and preventive eff ect of physical exercises in primary open-angle glaucoma. ACTA BIOMEDICA SCIENTIFICA 2021.

Abstract
The review assesses physical exercises as an additional non-pharmacological mean of combating the progression of primary open-angle glaucoma. The ophthalmic hypotensive effect is determined by the type of exercise, its duration and intensity. Moderate aerobic activity is preferred. Among dynamic exercises, jogging has the greatest hypotensive effect. Upper body isometric resistance training provides a more lasting decrease in ophthalmotonus. The decrease in intraocular pressure (IOP) in patients with glaucoma is several times more pronounced in comparison with healthy people and occurs regardless of the nature of the local drug antihypertensive therapy. After the termination of classes IOP returns to the previous level on average within a month. An increase in ocular perfusion pressure associated with physical activity dictates the appropriateness of physical exercise for patients with pseudo-normal pressure glaucoma. The combination of hypotensive, vascular, neuroprotective effects of physical activity with a high level of physical fi tness does not exclude a decrease in the risk of development and progression of primary open-angle glaucoma. The development of indications for the use of physical activity by patients with advanced glaucoma, including those who have undergone hypotensive surgery, remains relevant. The type, intensity, dosage and mode of performing the recommended physical exercises require an individual choice.

Abstract
Glaucoma, a progressive optic neuropathy characterized by retinal ganglion cell degeneration and visual field loss, is the leading cause of irreversible blindness worldwide. Intraocular pressure (IOP) is presently the only modifiable risk factor demonstrated to slow or halt disease progression; however, glaucomatous damage persists in almost 50% of patients despite significant IOP reduction. Many studies have investigated the non-IOP-related risk factors that contribute to glaucoma progression as well as interventions that can prevent or delay glaucomatous neurodegeneration and preserve vision throughout life, independently of IOP. A vast number of experimental studies have reported effective neuroprotection in glaucoma, and clinical studies are ongoing attempting to provide strong evidence of effectiveness of these interventions. In this review, we look into the current understanding of the pathophysiology of glaucoma and explore the recent advances in non-IOP related strategies for neuroprotection and neuroregeneration in glaucoma.

Abstract
Background This study aims to investigate the prevalence of glaucoma and its related factors among residents aged 40 and over in Jiangxi Province, China, and provide a scientific basis for the prevention and control of glaucoma. Methods The cluster sampling method was used to randomly select six townships. Similarly, eight villages were randomly selected from each sample township. A total of 5385 rural residents from 48 villages were collected for a questionnaire survey. A logistic regression model was used to explore the personal behavioral factors related to glaucoma. Results Among the 5385 participants, the prevalence rate of glaucoma was 1.4%. The logistic regression model found that alcohol consumption, vegetable consumption, physical exercise, daily reading time, and frequent reading environment were related to glaucoma. Conclusion To prevent the occurrence of glaucoma, it is important for rural residents to reduce the frequency of alcohol consumption, increase the frequency of vegetable consumption and physical exercise, control the length of daily reading, and read in a moderately lit environment.

Abstract
PURPOSE To evaluate the associations between medical check-up items (MCI) for fundus and intraocular pressure abnormality (FIPA) diseases in the Department of Health Management Centre, the Fifth Affiliated Hospital of Sun Yat-sen University (DHMC-FHS). PATIENTS AND METHODS Individuals who visited DHMC-FHS and underwent MCI between June 2017 to May 2019 were included, 3237 subjects. A total of 356 participants were diagnosed as FIPA and enrolled. The general clinical characteristics were collected. Diseases for FIPA diagnosed included five cohort, high intraocular pressure, diabetic retinopathy, hypertension fundus arteriosclerosis, large eye cup, and high myopia fundus changes. Possible impact factors of MCI included blood routine, B-ultrasound, heart rate, hypertension, hyperlipidemia, standard vision, cerebral arteriosclerosis, body mass, arterial/carotid arteriosclerosis, etc. Further, the Pearson's correlation coefficients and logistic regression analyses were used to examine associations between MCI and FIPA. RESULTS The weighted study population who belonged to FIPA included 356 subjects. There were significant differences in age, IOP, habitual exercise, smoking, sleep duration (P˂0.05) between FIPA and without FIPA. And RBC, Hemoglobin, B-ultrasound abnormal event, heart rate, systolic pressure, diastolic pressure, TC, LDL-C, standard vision, cerebral arteriosclerosis, body mass index, carotid arteriosclerosis were positively correlated with high intraocular pressure, hypertension fundus arteriosclerosis and high myopia fundus changes (P < .05). Possible prognosis risk factors, higher IOP, habitual exercise and more frequent smoking affect FIPA prognosis significantly [Odds ratio (OR) = 0.53, P = .01; OR = 0.13, P = .03; OR = 0.83; P = .04, respectively]. CONCLUSION Of FIPA participants, high intraocular pressure, hypertension fundus arteriosclerosis and high myopia fundus changes were shown a positive relationship with MCI. Control IOP, habitual exercise and less frequent smoking were regarded as positive associations with decreased FIPA. These findings could help us prevent and diagnose FIPA diseases in time via MCI.

Abstract
PURPOSE To evaluate exercise-induced changes in ocular blood flow (OBF) parameters in primary open-angle glaucoma (POAG) patients. METHODS A prospective observational study was carried out, in which medically treated patients with POAG were enrolled. Following inclusion, all patients performed a 40-min cycloergometry in a standardized fashion. The following parameters were measured and compared immediately before and 1 and 30 min after the exercise: intraocular pressure (IOP; Goldman applanation tonometry), mean arterial pressure (MAP), ocular pulse amplitude (OPA; assessed by dynamic contour tonometry), and ocular perfusion pressure (OPP; 2/3 MAP - IOP). In addition, we investigated possible factors associated with OBF parameter changes immediately after exercise. RESULTS A total of 30 eyes (30 patients; mean age was 62.9 ± 1.7 years) were included. Most patients were women (53%), and median visual field mean deviation index was -3.5 dB. Both MAP (mean change, 21%) and IOP (mean change, 17.3%) increased significantly immediately after the workout (p < 0.01), persisting higher than baseline following 30 min (p < 0.01%). Regarding OBF parameters, both OPA (mean change, 58.8%) and OPP (mean change, 21.7%) increased significantly immediately after the workout and persisted higher than baseline 30 min after the workout (p < 0.01). Regression analysis revealed that only age was significantly associated with OPA variation (R2 0.14; p < 0.05). No significant associations were found for OPP (p ≥ 0.19). CONCLUSION Aerobic exercise leads to a significant short-time increase in OBF parameters in patients with POAG. Even though IOP seems to present a modest elevation, it is accompanied by a significant increase in MAP, leading to higher OBF measurements. Exercise-induced short-term changes and its possible implications for glaucoma prognosis deserve further investigation.

Abstract
PURPOSE OF REVIEW Although reducing the intraocular pressure (IOP) through medications, laser or surgery remains the primary means of glaucoma treatment, there is increasing evidence during the last decade that environmentally modifiable factors may help to prevent glaucoma or its progression through different mechanisms that may or may not involve lowering IOP. Additionally, patients are increasingly interested in maintaining a healthy lifestyle and taking an active role in the management of their disease. Therefore, the aim of this review is to summarize the current evidence regarding environmentally modifiable factors such as lifestyle, exercise, and nutrition in the pathogenesis of glaucoma. RECENT FINDINGS In the last decade, large population-based studies have helped to identify possible environmentally modifiable protective and risk factors with regard to glaucomatous disease. Smoking cessation; moderate aerobic exercise; recommended weight; and a balanced diet including green leafy vegetables, omega fatty-acids, and moderate intake of hot tea and coffee have been reported to be possibly protective against developing glaucoma or its progression. SUMMARY Modifiable environmental factors such as lifestyle, exercise, and nutrition may play a role in glaucoma pathogenesis. Large prospective studies with long-term follow-up should be encouraged to corroborate these findings, which may guide future treatments for our patients, some of which may not be limited to IOP reduction.

Abstract
Abstract Objective: The objective of this study was to compare the cognitive performance of elderly who are enrolled in a physical activity (PA) program with those who are not, considering some sociodemographic variables that are related to the practice of cognitive activities. Method: 59 elderly people participated in this study divided into control group (CG) and gymnastics group (GG). The Vienna Test System® was used to estimate the attention and concentration capacities, simple reaction time and peripheral perception. To test the normality of the data it was used the Shapiro Wilk Test. The association between PA and socioeconomic variables was verified by Chi-Square Test and Fisher Exact Test. To compare of differences between groups the Mann Whitney U-test for variables with non-parametric distribution and the Student T-test for independent samples for other variables were used. Result: There were no significant differences in the performance of the groups, except in the capacity of attention and concentration in which CG presented best performance (p=0.01). Factors as schooling (p=0.02), income (p=0.001) and regular practice of handcrafts (p=0.06) can explain the best performance of CG. Conclusion: This study found no evidence that the practice of physical activity can generate some cognitive benefit in the elderly when compared to the elderly who did not practice regular physical activity. However, we perceive the existence of other aspects that influence on the cognition, such as schooling, sociocultural level and the reading habit, that have a significant importance degree in the analysis.

Abstract
The benefits of physical exercise on health and well-being have been studied in a wide range of systemic and ocular diseases, including glaucoma, a progressive optic neuropathy characterized by accelerated apoptosis of retinal ganglion cells (RGCs). Elevated intraocular pressure (IOP) and insufficient ocular perfusion have been postulated to be the two main theories in glaucoma development and progression. The effects of exercise in these two aspects have been demonstrated by numerous researches. A review in 2009 focusing on these two theories concluded that exercise results in transient IOP reduction but an inconsistent elevation in ocular perfusion. However, the majority of the studies had been conducted in healthy subjects. Over the past decade, technological advancement has brought forth new and more detailed evidence regarding the effects of exercise. Moreover, the neuroprotective effect of exercise by upregulation of neurotrophin and enhancement of mitochondrial function has been a focus of interest. Apart from visual impairment, the mental health issues in patients with glaucoma, which include anxiety and depression, should also be addressed. In this review, we mainly focus on publications from the recent years, so as to provide a comprehensive review on the impact of physical exercise on IOP, ocular perfusion, neuroprotection and mental health in patients with glaucoma.
