Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
With dietary measures such as salt intake and sometimes with low-dose steroids, a drop in blood pressure, especially during sleep, can often be prevented. These nightly "dips" of blood pressure in normal tension glaucoma patients with Flammer syndrome can significantly damage the sensory cells of the retina.
Shock, such as hypovolemia, even in mild form such as when drawing blood. Standing up suddenly (see orthostatic hypotension), especially if sick, hungover, or experiencing low blood pressure. Fatigue; Hyperventilation, paradoxically: self-induced hypocapnia, such as in the fainting game or in shallow water blackout. Overexertion; Panic attack
Low blood pressure then is a pre-morbid sign and potentially too late for optimum outcomes. [14] The goal was to create an easy-to-use and impartial system that improved outcomes. Monaghan and his multidisciplinary team created what is referred to as PEWS, pediatric early warning signs.
"Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
Hypotony may occur either due to decreased production of aqueous humor or due to increased outflow. Hypotony has many causes including post-surgical wound leak from the eye, chronic inflammation within the eye including iridocyclitis, hypoperfusion, tractional ciliary body detachment or retinal detachment. [5]
A low blood pressure - whether consistently low or with sudden pressure drops - is associated with NTG as are conditions like Flammer syndrome and obstructive sleep apnea. [2] Flammer syndrome has been attributed to increase the likelihood of ganglion cell damage in normal tension glaucoma patients with disc hemorrhages as a characteristic ...
