Most common and affordable diagnostic tests for Glaucoma

Most common and affordable diagnostic tests for Glaucoma : Glaucoma, a group of eye conditions that damage the optic nerve, often leads to vision loss if not detected early. Fortunately, several common and affordable diagnostic tests can aid in early detection and management. One widely used test is tonometry, which measures intraocular pressure (IOP). Elevated IOP is a significant risk factor for glaucoma. The non-contact version, often called the "air puff" test, is particularly affordable and convenient. Another essential test is ophthalmoscopy, where an eye care professional examines the optic nerve for damage. This test is often included in routine eye exams, making it both accessible and cost-effective. Visual field testing, or perimetry, assesses peripheral vision, which is typically affected first by glaucoma. While more comprehensive, basic versions of this test are still relatively affordable. Additionally, pachymetry measures corneal thickness, which can influence IOP readings and glaucoma risk. This quick and inexpensive test helps provide a more accurate assessment. Finally, optical coherence tomography (OCT) is increasingly used to visualize the optic nerve and retinal layers in detail. Although slightly more costly than the other tests, its non-invasive nature and high accuracy make it a valuable tool in glaucoma diagnosis and monitoring. Collectively, these tests offer effective and affordable means to detect and manage glaucoma early, potentially preserving vision.
