What is Hypotony of the eye?

Hypotony is usually defined as an intraocular pressure (IOP) of 5 mm Hg or less. Low IOP can adversely impact the eye in many ways, including corneal decompensation, accelerated cataract formation, maculopathy, and discomfort. Clinically significant changes occur more frequently as the IOP approaches 0 mm Hg.

What is Hypotony of the eye?

Hypotony is usually defined as an intraocular pressure (IOP) of 5 mm Hg or less. Low IOP can adversely impact the eye in many ways, including corneal decompensation, accelerated cataract formation, maculopathy, and discomfort. Clinically significant changes occur more frequently as the IOP approaches 0 mm Hg.

What is the treatment for Hypotony?

Treatment options include argon laser photocoagulation, cryotherapy, external diathermy, ciliary body suturing, and vitrectomy with endotamponade. Clefts can spontaneously close and result in a dramatic rise in IOP. Miotics should be avoided to prevent recurrence of cleft opening.

Can Hypotony cause blindness?

Delayed treatment of hypotony can result in permanent changes in the retina and choroid and cause vision loss [12, 15].

What is Hypotony maculopathy?

Hypotony maculopathy is a condition that may result in visual deterioration from choroidal folds or optic disc edema. Optic disc edema can result from altered translaminar pressure gradients (lowered intraocular pressure, increased cerebrospinal fluid pressure, or increased orbital pressure).

What does an eye pressure of 5 mean?

When the pressure is below 5 mm HG, doctors call it ocular hypotony. It can make you more likely to get several eye problems, including: Swelling in the cornea, the clear outer dome of your eyes. Cataracts. Damage to the macula, the light-sensing part of the retina that allows you to see.

Can your Toop be too low?

A condition called hypotony is generally considered to be less than 6 mm Hg. When the eye pressure is too low it can cause several distortions of the retina, lens and cornea that can degrade vision. Treatment of hypotony is especially important when it is associated with visual loss.

Is hypotony reversible?

Hypotony was reversed in 100 percent of cases and all but two patients (87 percent) achieved success, as defined in the study.

Is 7 a good eye pressure?

Normal IOP is usually between 12 and 22 mm Hg. Similar to using inches as a way to report length, mm Hg refers to millimeters of mercury and is a way to report pressure. An eye is considered hypotonous when the IOP drops below 10 mm Hg. However, hypotony may not be a problem unless the IOP drops below 5 mm Hg.

Can Hypotony cause eye pain?

“The bigger concerns, even in patients who do not have visible choroidal detachments or hypotony maculopathy, are that they can have blurred fluctuating vision and some ocular discomfort,” Dr.

Can Hypotony cause corneal edema?

Corneal edema associated with hypotony keratopathy is frequently reversible when IOP increases. This suggests that the edema is due to endothelial dysfunction, not endothelial loss. Successful treatments for hypotony keratopathy include trabeculectomy revision and cataract extraction.

What medications increase eye pressure?

The classes of medications that have the potential to induce angle closure are topical anticholinergic or sympathomimetic dilating drops, tricyclic antidepressants, monoamine oxidase inhibitors, antihistamines, antiparkinsonian drugs, antipsychotic medications, and antispasmolytic agents.
