Understanding Applanation Tonometry: A Critical Tool in Eye Care

When it comes to safeguarding your vision, early detection of eye conditions like glaucoma is paramount. One essential procedure in modern eye care is Applanation Tonometry , a highly accurate method for measuring intraocular pressure (IOP), the pressure inside your eyes. Elevated IOP is one of the primary risk factors for glaucoma, a condition that can lead to irreversible vision loss if left untreated. What is Applanation Tonometry? Applanation Tonometry is a technique used by eye care professionals to assess the force required to flatten a small, predetermined area of the cornea. This measurement helps determine the pressure within the eye. The procedure is painless and quick, often performed during routine comprehensive eye exams. How Applanation Tonometry Works The test typically involves a specialized instrument called a tonometer , which is integrated into a slit-lamp microscope. Here's what to expect during the procedure: Preparation : Anesthetic eye drops are applied to ...
