Quizplus · Accepted Answer

Pachymetry is a test used to measure the thickness of the cornea, which is an important factor in accurately measuring intraocular pressure. A thin cornea can give false low readings on intraocular pressure tests, while a thick cornea can give false high readings. Knowing the accurate thickness of the cornea is crucial in diagnosing and managing glaucoma, especially in patients with a family history of the condition.
