Various underlying mechanisms [3] propose to explain the cause of decrease in IOP during pregnancy, namely, an increase in uveoscleral outflow as a result of hormone levels modification, a decrease in systemic vascular resistance, decrease in episcleral venous pressure, increased tissue elasticity, reduction in the aqueous humor production, and decreased corneoscleral rigidity.
This can be explained by the lack of patients with OIS in our patient group and the absence of ciliary body ischemia caused by stenosis, in which case there is no reduction in aqueous humor production.
Hypotony suggests inadequate aqueous humor production and can limit the visual potential of an eye through complications such as retinal folds at the macula (i.
Aqueous humor is a transparent, watery fluid that provides nutrition to the front part of the eye.
However, there have been reports on pronounced inflammation of the anterior segment of an eye, accompanied by pain, fibrin deposition in the aqueous humor of the anterior chamber [7,8], and even by choroidal effusion [13,16].
Anterior chamber paracentesis, aspiration and analysis of aqueous humor provide a valuable diagnostic procedure that optimises treatment and subsequent prognosis and poses a very limited risk.
But it is generally agreed that IOP elevation result from reduction in facility of aqueous humor outflow (Douglas H et al 2005 Basic and Clinical Science Course 2011-12).
Eyes under pressure The front half of the eye contains a clear, watery fluid called aqueous humor.
Tissue plasminogen activator and urokinase-type plasminogen activator are present in the aqueous humor normally and an intensive plasminogenesis exists in the aqueous humor.
In all species studied to date, ocular hypertension is invariably caused by impaired aqueous humor outflow rather than by hypersecretion.
Ongoing lab research on this substance indicates that NO successfully increases the outflow of the aqueous humor (fluid inside the eye) to the drainage system.
Flowing through this chamber is a liquid, called the aqueous humor, which supplies oxygen and nutrients to the cornea and lens and helps maintain the shape of the eyeball.
DISCUSSION: Intra ocular pressure is a function of the rate at which aqueous humor enters the eye (in flow) and the rate at which it leaves the eye (out flow).
It is filled with clear, watery fluid known as aqueous humor that is continuously produced by cells in this area to nourish the cornea, iris, and lens.
