Ambulatory blood pressure patterns in patients with retinal vein occlusion
Conclusion: Our data suggest an association between RVO and nondipper BP pattern. Ambulatory BP monitoring may be useful in the evaluation of patients with RVO by identifying those who may benefit from more aggressive BP control.

Macular degeneration and aspirin use
Conclusion: Overall, the number, size, and quality of the cardiovascular studies recommending aspirin use are far superior to the fewer, smaller and conflicting studies suggesting a possible adverse effect of aspirin use in relation to AMD. The benefits of aspirin usage include preserving the duration and quality of life by decreasing stroke and heart attack risk. These benefits seem to far outweigh the theoretical risks of possibly exacerbating wet AMD, which can be reasonably controlled with anti-VEGF therapy.

Do Patients with Retinal Artery Occlusion Need Urgent Neurological Evaluation?
Whether patients with central (CRAO) or branch (BRAO) retinal artery occlusion should undergo urgently a detailed neurological workup for ischemic stroke is controversial. In a survey1 of physicians in the United States, among those who responded, 35% of ophthalmologists but 73% to 86% of neurologists and neuro-ophthalmologists sent their patients with acute CRAO for immediate neurological workup. An anonymous survey of members of the American Academy of Neurology Stroke Section and vitreoretinal specialists of the American Academy of Ophthalmology showed that 75% neurologists pursue a hospital-based evaluation within 12 h...

Presence of diabetic retinopathy is associated with worse 10 ‐year mortality among Indigenous Australians in Central Australia: The Central Australian ocular health study
Conclusion and RelevanceThe presence of any DR among those with DM, was associated with a 75% greater 10 ‐y all‐cause mortality rate and were more likely to die from renal failure or stroke. We recommend that whenever DR is noted among Indigenous Australians with DM, that they be immediately referred for investigation and management of risk factors, which might predispose to renal failure and strok e.

Central retinal artery occlusion – a new, provisional treatment approach
The retinal ganglion cells infarcted in central retinal artery occlusion (CRAO) are the somata of the optic nerve axons, part of the central nervous system. Consequently, CRAO with inner retinal infarction is a small vessel stroke, usually with the devastating consequence of severe visual loss in the affected eye. At present, there is no generally accepted, evidence-based therapy of non-arteritic CRAO in contrast to ischemic cerebral stroke that has well accepted treatment protocols. Widely divergent and controversial therapeutic options for CRAO reflect the desperation of treating physicians and disparate conflicting studies.

Seeing is not believing
Alexia without agraphia is an interesting and distinctive visual disconnection syndrome that results from damage to the dominant left occipital lobe and splenium of the corpus callosum. Although the patient can see individual letters (from the intact right occipital cortex), the damage to the corpus callosum results in disconnection of the transmission of information from the intact right occipital lobe to the intact left angular gyrus. This disconnection produces the symptom of alexia without agraphia. In the acute setting, posterior cerebral artery infarct is the most common cause. Prompt recognition of this unique strok...

Obstructive Sleep Apnea in Neuro-Ophthalmology
Conclusions: OSA is associated with many diseases seen in neuro-ophthalmology clinics. More studies are required to assess the real ability of CPAP to reverse pathological changes. Ophthalmologists can screen for undiagnosed OSA in patients presenting with certain eye diseases.

Assessment of Cerebral Vasomotor Reactivity in Patients With Primary Open-angle Glaucoma and Ocular Hypertension Using the Breath-Holding Index
Précis: Patients with ocular hypertension (OHT) do not show impaired cerebral vasodilation responses to hypercapnia but patients with primary open-angle glaucoma (POAG) do. Impaired vasoreactivity in patients with POAG may have neuronal or vascular origins and increase stroke risk. Purpose: To investigate changes in cerebral blood flow and cerebral vasomotor reactivity using the breath-holding index in patients with POAG and OHT, to examine whether these parameters contribute to the risk of ischemic stroke. Methods: Thirty patients with POAG, 30 patients with OHT, and 30 age- and sex-matched healthy cont...

SARS-CoV-2 Impairs Vision
Conclusions: This mini review shows that impaired vision may be the initial manifestation of COVID-19, that all sections of the visual tract may be affected and causative for visual impairment in COVID-19 patients, and that SARS-CoV-2 manifests along the visual tract with ischemia, focal infection, and immunological reactions.

Associations of ophthalmic and systemic conditions with incident dementia in the UK Biobank
CONCLUSIONS: AMD, cataract and DRED but not glaucoma are associated with an increased risk of dementia. Individuals with both ophthalmic and systemic conditions are at higher risk of dementia compared with those with an ophthalmic or systemic condition only.PMID:34518160 | DOI:10.1136/bjophthalmol-2021-319508
