Which condition is typically assessed using tonometry?

Tonometry is a diagnostic procedure used to measure the pressure inside the eye, known as intraocular pressure (IOP). This measurement is critical in the assessment of glaucoma, a condition characterized by damage to the optic nerve, often associated with high IOP.

Elevated intraocular pressure can be a significant risk factor for developing glaucoma, and regular tonometry tests help in monitoring and managing this condition. By identifying elevated pressure levels early, healthcare professionals can recommend treatments to lower the pressure and reduce the risk of vision loss associated with glaucoma.

Other conditions listed, such as cataracts, macular degeneration, and retinal detachment, are not primarily evaluated through tonometry. While these conditions may impact vision, they do not involve the direct measurement of intraocular pressure as part of their standard assessment. Therefore, tonometry's specific focus on pressure measurement makes it particularly relevant for diagnosing and managing glaucoma.
