"Pachymetry" Natural Recordings by Native Speakers
Pachymetry is a term used in ophthalmology to describe a non-invasive test that measures the thickness of the cornea, which is the clear outer layer at the front of the eye. The test is usually performed with an ultrasound pachymeter, which sends a painless sound wave through the cornea and measures the distance the wave travels before being reflected back. This measurement is used to diagnose conditions such as keratoconus, where the cornea becomes thin and irregular, and to monitor the progression of these conditions over time.
Pachydermia refers to a condition characterized by abnormally thick skin, particularly on the hands and feet. It can be a symptom of certain medical conditions, such as eczema, psoriasis, or vitamin deficiencies. The term specifically refers to the thickening of the skin on the palmar surface of the hands or plantar surface of the feet, which can cause discomfort, itching, and difficulty moving the affected joints.
A pachymeter is a medical device used to measure the thickness of the cornea, which is the clear outer layer of the eye. The measurement is typically taken to diagnose and monitor conditions such as glaucoma, keratoconus, and Fuchs' dystrophy, as well as to plan and follow up on surgical procedures.
