Understanding Glaucoma: Know Its Causes, And Diagnosis Causes of Glaucoma: Increased Intraocular Pressure (IOP): The most significant risk factor for glaucoma is elevated pressure in the eye, which can damage the optic nerve. Age: People over 60 are at higher risk, especially for open-angle glaucoma. Ethnicity: African Americans, Asians, and Hispanics are at higher risk for certain types of glaucoma. Family History: Having a family history of glaucoma increases the risk. Medical Conditions: Diabetes, high blood pressure, and heart disease can increase the risk of developing glaucoma. Eye Injuries: Trauma to the eye can result in increased eye pressure. Diagnosis of Glaucoma: Tonometry: Measures the pressure inside the eye. Ophthalmoscopy: Examines the optic nerve for signs of damage. Perimetry: Tests the visual field for areas of vision loss. Gonioscopy: Inspects the drainage angle of the eye to determine whether it's open or closed. Pachymetry: Measures the thickness of the cornea, which can influence eye pressure readings.
