[59] In November 2019, the Mayo Clinic, in a joint partnership with SEHA Abu Dhabi Health Services Co, invested $50 million into a 741-bed hospital in the United Arab Emirates for a 25% stake.

The Bates method is an ineffective and potentially dangerous alternative therapy aimed at improving eyesight.Eye-care physician William Horatio Bates (1860–1931) held the erroneous belief that the extraocular muscles caused changes in focus and that "mental strain" caused abnormal action of these muscles; hence he believed that relieving such "strain" would cure defective vision.
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
A constriction response , [2] is the narrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hypertension medications. Constriction of the pupil occurs when the circular muscle , controlled by the parasympathetic nervous system (PSNS), contracts, and also to an extent when the radial muscle relaxes.
Blepharospasm is aggravated by fatigue, stress, and environmental factors such as wind or air pollution. [ 21 ] Although blepharospasm is defined as a bilaterally symmetric disorder that affects both eyes, some research has reported unilateral onset.
Because eye movements and other bilateral stimulation techniques do not uniquely contribute to EMDR treatment efficacy, EMDR has been characterized as a purple hat therapy, i.e., its effectiveness is due to the same therapeutic methods found in other evidence-based psychotherapies for PTSD, namely exposure therapy and CBT techniques, without ...
In post-secondary students, research on mindfulness-based stress reduction has demonstrated that it can reduce psychological distress, which is common in this age range. In one study, the long-term impact of an 8-week Mindfulness-Based Stress Reduction (MBSR) treatment extended to two months after the intervention was completed. [50]
