A study with 1636 persons aged 40-80 who had an intraocular pressure above 24 mmHg in at least one eye, but no indications of eye damages, showed that after five years, 9.5% of the untreated participants and 4.4% of the treated participants had developed glaucomatous symptoms, meaning that only about one in 10 untreated people with elevated ...
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.

[3] When concentrating on a visually intense task, such as continuously focusing on a book or computer monitor, the ciliary muscles and the extraocular muscles are strained. This causes discomfort ...
In these eyes, an elevated pressure in the retinal veins has been observed. [ 10 ] Glaucoma patients with Flammer syndrome show some specific clinical signs like increased frequency of optic disc haemorrhages, activated retinal astrocytes, elevated retinal venous pressure, optic nerve compartmentalization, and fluctuating diffuse visual field ...
Post-traumatic stress disorder (PTSD) People with PTSD are prone to sensory overload due to a general hypersensitivity to sensory stimuli partially caused by sensory gating issues; this is supported by the fact that people with PTSD have impaired P50 gating and an inability to filter redundant auditory stimuli.
People with coronary artery disease, or narrowing of the blood vessels supplying their heart, may develop symptoms such as: Chest pain that often gets worse with stress or physical activity ...
Differences in pressure between the two eyes are often clinically significant, and potentially associated with certain types of glaucoma, as well as iritis or retinal detachment. Intraocular pressure may become elevated due to anatomical problems, inflammation of the eye, genetic factors, or as a side-effect from medication .
Pulmonary arterial hypertension (PAH) is a serious condition that happens when the tiny vessels in your lungs narrow, resulting in high blood pressure. Normally, the pulmonary artery supplies ...
