How is intraocular pressure measured
WebOcular hypertension is when the pressure inside the eye is higher than normal. Eye pressure is measured in millimeters of mercury (mmHg). Normal eye pressure ranges from 10 to 21 mmHg. WebAim: Large diurnal intraocular pressure (IOP) fluctuation is a single most independent risk factor for glaucoma progression besides raised IOP. The major limitation of Goldman applanation tonometer (GAT) is its inability to measure night IOP without disturbing the patient's sleep. We discussed the methods available for the 24-hour IOP monitoring and …
