What is mean by Hypotony?

What is mean by Hypotony?

Hypotony is defined as low intraocular pressure (IOP) and occasionally is associated with decreased vision. 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.

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.

What are the symptoms of Hypotony?

Physical Examination

  • Intraocular pressure less than 6.5mm Hg.
  • Painless, decreased vision.
  • Hyperopic shift in refraction.
  • Characteristic fundus changes: chorioretinal folds, vascular tortuosity, and optic disc swelling.

Can Hypotony cause blindness?

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

Is low eye pressure bad?

‘ Low pressures can sometimes be asymptomatic, and not all chronically low IOPs lead to irreversible vision loss,” Dr. Weinberg said. “But low IOP and poor visual acuity may have obvious correlates.” Hypotony can be defined in terms of time, as acute, transient, finite, prolonged, or persistent.

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.

What home remedy can I use for eye pressure?

These tips may help you control high eye pressure or promote eye health.

  1. Eat a healthy diet. Eating a healthy diet can help you maintain your health, but it won’t prevent glaucoma from worsening.
  2. Exercise safely.
  3. Limit your caffeine.
  4. Sip fluids frequently.
  5. Sleep with your head elevated.
  6. Take prescribed medicine.

Does lack of sleep affect eye pressure?

Because lack of sleep is detrimental to your health, it can eventually lead to more serious eye problems such as glaucoma. Glaucoma is a condition where too much pressure builds up inside the eye. Eventually glaucoma can lead to loss of vision.

Is 14 a good eye pressure?

Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal. When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.

What is considered dangerously high eye pressure?

Anything below 12mm Hg is indicative of hypotony, or low eye pressure, and anything above 22mm HG may signal intraocular hypertension, or high eye pressure. While high eye pressure is not inherently dangerous, it increases your risk of developing glaucoma, a progressive eye disease that can result in blindness.

What is considered normal eye pressure?

Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal. When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension. High eye pressure alone does not cause glaucoma. However, it is a significant risk factor.

What causes low eye pressure?

Dr. Myers: The most common cause of low pressures is surgery. However, sometimes glaucoma medications can contribute to abnormally low pressures. Also, trauma to the eye or inflammation in the eye may lower (or raise) the pressure.
