Intraocular Pressure Calculator

Calculate intraocular pressure based on Schlemm's canal diameter and aqueous humor flow rate

Intraocular Pressure (IOP) Result

--

Calculation Formula

IOP = (8 × Flow Rate) / Schlemm's Canal Diameter

Where:
IOP = Intraocular Pressure (mmHg)
Flow Rate = Aqueous Humor Flow Rate (μL/min)
Schlemm's Canal Diameter = Inner diameter of Schlemm's canal (μm)

Intraocular Pressure Calculator Usage Guide

Learn how to use the Intraocular Pressure Calculator and its working principles

How to Use This Calculator

  1. Enter the Schlemm's Canal Diameter in micrometers (μm). This is the inner diameter of the canal that drains aqueous humor from the eye.
  2. Enter the Aqueous Humor Flow Rate in microliters per minute (μL/min). This represents how quickly aqueous humor is produced in the eye.
  3. Click the "Calculate" button to compute the estimated intraocular pressure (IOP).
  4. The result will be displayed in millimeters of mercury (mmHg), which is the standard unit for measuring IOP.

Understanding Intraocular Pressure

Intraocular pressure (IOP) is the fluid pressure inside the eye. Normal IOP typically ranges from 10 to 21 mmHg. Elevated IOP is a major risk factor for glaucoma, a group of eye diseases that can damage the optic nerve and lead to vision loss.

Calculation Principle

This calculator uses a simplified model based on the relationship between aqueous humor flow rate and Schlemm's canal diameter. According to this model, IOP is inversely proportional to Schlemm's canal diameter and directly proportional to aqueous humor flow rate.

Limitations

Keep in mind that this is a simplified calculation for educational purposes. Actual IOP measurements typically require specialized equipment and may be influenced by many other factors not included in this calculation.
