The most common process would be the Schiotz tonometer, which makes use of a weighted plunger to indent the cornea. The outcomes of this technique rely on the used power, and corneal thickness and rigidity might have an effect.
Knowing the strengths and limitations of various tonometer types is very important for ophthalmologists and optometrists to help make knowledgeable choices around the most fitted instrument for every affected person and situation.
There are lots of types of applanation tonometer, with Goldman and Perkins tonometer getting the most often Utilized in scientific follow. Goldman tonometry is taken into account the gold common and is Utilized in most clinical options.
This know-how could also supply details about corneal biomechanics and continues to be revealed being valuable inside the diagnosis of glaucoma and various ocular ailments.
Issues or inability to utilize the tonometer: Selected tonometry, such as gold typical Goldmann applanation, can only be utilised by using a collaborative personal in an upright posture.
Consequently, precision and precision in measuring IOP are important necessities to predict and observe ailment development.5
