The association between bouted and non-bouted physical activity on retinopathy prevalence.
CONCLUSION: In this nationally representative sample of adults, those who engaged in non-bouted physical activity had reduced odds of a diagnosis of moderate-to-severe retinopathy. PMID: 28818533 [PubMed - as supplied by publisher]

Epidemiology of a Rare Event
Retinal emboli are rare, with a prevalence in most of the relatively few studies on the subject, to my knowledge, of approximately 1 in 100 adults and an even smaller annual incidence. The study by Cheung et al in the present issue ofJAMA Ophthalmology involves the multiethnic population of Singapore and found that retinal emboli were present in only 88 of 9978 individuals who had retinal photographs (0.9%). This randomly selected sample of adults aged 40 to 80 years comprised, in almost equal numbers, of members of the 3 major ethnic groups residing in Singapore: Chinese, Malay, and Indian. Cheung et al provided data rele...

Dietary patterns and retinal vessel caliber in the Irish Nun Eye Study
ConclusionIn this cohort of older women with a restricted lifestyle, an unhealthy DP was independently associated with an unfavorable retinal profile, namely a widening of retinal venules and narrowing of retinal arterioles. Key words: Dietary

Genetic polymorphisms associated with the prevalence of retinal vein occlusion in a Greek population
ConclusionsAGTR1 A1166C andGpla/lla C807T/G873A polymorphisms are likely to be risk factors for CRVO.Adiponectin + 276 G/T SNP is likely to predispose to RVO in older subjects.

Blood pressure variability and microvascular dysfunction: the Maastricht Study
Conclusion: Greater systolic and diastolic BPV was associated with higher albuminuria, but not with CSVD features, flicker light-induced retinal arteriolar and venular dilation response, heat-induced skin hyperemia and plasma biomarkers of MVD. This suggests that the microvasculature of the kidneys is most vulnerable to the detrimental effects of greater BPV.

The potential role of microvascular pathology in the neurological manifestations of coronavirus infection
We present the hypothesis that pre-existing vascular damage (due to aging, cardiovascular disease, diabetes, hypertension or other conditions) facilitates infiltration of the virus into the central nervous system (CNS), increasing neuro-inflammation and the likelihood o f neurological symptoms. We also discuss the role of a neuroinflammatory cytokine profile in both blood–brain barrier dysfunction and macrovascular disease (e.g. ischemic stroke and thromboembolism). Future studies are needed to better understand the involvement of the microvasculature in coronavi rus neuropathology, and to test the diagnostic potential o...

How Good is Photoscreening For Young Children ’ s Vision Problems?
This study showed that not only was smartphone photoscreening feasible, but was quite good at screening for potential vision problems. Smartphone photoscreening has the advantages of being more ubiquitously available and thus children in almost any location can be screened. A study of photoscreening using a handheld digital photoscreener in primary care offices validated the technology showing an overall referral rate of 10% to an ophthalmologist with suspected astigmatism, anisometropia and strabismus being the most common reasons. The overall positive predictive rate was 0.60. “…[O]ver 60% of children referre...

Serum levels of antibodies against oxidation-specific epitopes are decreased in patients with retinal vein occlusion
Conclusion: These prospective data show that antibodies against oxidation-specific epitope are lower in patients with RVO compared with control patients and support the concept that oxidative stress and inflammation play key roles in the development and subsequent complications in RVO.

Prevalence and associated relating factors in patients with hereditary retinal dystrophy: a nationwide population-based study in Taiwan
CONCLUSIONS: 74% of the diagnosed HRD are retinitis pigmentosa. Population-based data suggested an increased incidence of cataract in younger patients, whereas older HRD patients are more susceptible to develop CME. Further work is needed to elucidate the mechanism between these ophthalmological disorders and HRD.PMID:35396285 | DOI:10.1136/bmjopen-2021-054111

The New Era of Retinal Imaging in Hypertensive Patients
Structural and functional alterations in the microcirculation by systemic hypertension can cause significant organ damage at the eye, heart, brain, and kidneys. As the retina is the only tissue in the body that allows direct imaging of small vessels, the relationship of hypertensive retinopathy signs with development of disease states in other organs have been extensively studied; large-scale epidemiological studies using fundus photography and advanced semi-automated analysis software have reported the association of retinopathy signs with hypertensive end-organ damage includes the following: stroke, dementia, and coronar...

Sensors, Vol. 22, Pages 4310: Cardiovascular Disease Diagnosis from DXA Scan and Retinal Images Using Deep Learning
In this study, we aimed at diagnosing CVD using a novel approach integrating information from retinal images and DXA data. We considered an adult Qatari cohort of 500 participants from Qatar Biobank (QBB) with an equal number of participants from the CVD and the control groups. We designed a case-control study with a novel multi-modal (combining data from multiple modalities—DXA and retinal images)—to propose a deep learning (DL)-based technique to distinguish the CVD group from the control group. Uni-modal models based on retinal images and DXA data achieved 75.6% and 77.4% accuracy, respective...
