The Schiotz Tonometer is a type of handheld ophthalmic instrument used to measure intraocular pressure in the eye. It is named after its inventor, Bjørn Schiotz. The tonometer uses the principle of indentation tonometry to estimate the IOP based on the amount of force required to flatten a specific area of the cornea.
- Pen-like Design: Schiotz Tonometers typically have a pen-like design with a plunger and a weighted tip.
- Weighted Tip: The tip of the tonometer is weighted to exert a specific force on the cornea during the examination.
- Scale or Gauge: The instrument features a scale or gauge that displays the indentation depth of the cornea, allowing for the estimation of intraocular pressure.
- Various Models: There may be different models within the Schiotz Tonometer family, such as the Schiotz A, B, C, or other designations, which could represent variations in features or specifications.
- Intraocular Pressure Measurement: The primary use of the Schiotz Tonometer is to measure intraocular pressure. It is commonly used in ophthalmology clinics and eye care settings.
- Glaucoma Screening: The tonometer helps in screening for glaucoma, a condition characterized by increased intraocular pressure that can lead to optic nerve damage and vision loss.
- Monitoring Glaucoma Treatment: For patients diagnosed with glaucoma, regular tonometry examinations are essential to monitor the effectiveness of treatment in lowering intraocular pressure.
- Diagnostic Tool: The Schiotz Tonometer is used as a diagnostic tool to assess the risk of glaucoma and other ocular conditions associated with abnormal intraocular pressure.
- Comparison to Goldmann Applanation Tonometer: The Schiotz Tonometer can be used to calibrate and compare the results with the Goldmann applanation tonometer, which is considered the gold standard for IOP measurement.
