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. Intraocular ...
Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [1] [2]For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3]
Tonometry is the procedure that eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye.It is an important test in the evaluation of patients at risk from glaucoma. [1]
A major risk factor for glaucoma is increased pressure within the eye, known as intraocular pressure (IOP). [1] It is associated with old age, a family history of glaucoma, and certain medical conditions or the use of some medications. [6] The word glaucoma comes from the Ancient Greek word γλαυκός (glaukós), meaning 'gleaming, blue ...

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] Eye inflammation, medications including anti glaucoma drugs, or proliferative vitreoretinopathy causes decreased production. [6]

Pressure is applied to the cornea until the inner edges of two semicircular fluorescein mires come into contact, forming a continuous circle. The corresponding reading on the tonometer scale represents the IOP of the measured eye. Intraocular pressure (IOP) can be measured by tonometry devices. The eye can be thought of as an enclosed ...
