Glaucoma in a 58-year-old woman without diabetes is most commonly <\/span>primary open-angle glaucoma (POAG)<\/span><\/span>, but other types and risk factors must be considered. Below is a concise, evidence-based overview of likely causes and contributing factors.<\/span><\/span><\/span><\/p>\n
\n

Most Common Cause: Primary Open-Angle Glaucoma (POAG)<\/span><\/span><\/span><\/span><\/strong><\/p>\n

    \n
  • Mechanism<\/span><\/span>: Gradual blockage of aqueous humor drainage through the trabecular meshwork \u2192 elevated intraocular pressure (IOP) \u2192 optic nerve damage.<\/span><\/span><\/li>\n
  • Why at age 58?<\/span><\/span> Incidence rises sharply after age 40\u201350; ~2\u20133% of people >60 have POAG.<\/span><\/span><\/li>\n
  • Risk factors (independent of diabetes)<\/span><\/span>:<\/span><\/span>\n
      \n
    1. Age<\/span><\/span> (strongest non-genetic risk)<\/span><\/span><\/li>\n
    2. Family history<\/span><\/span> (3\u20136\u00d7 risk if first-degree relative affected)<\/span><\/span><\/li>\n
    3. Race<\/span><\/span>: Higher prevalence and earlier onset in <\/span>African ancestry<\/span><\/span>; also elevated in <\/span>Hispanic\/Latino<\/span><\/span> populations<\/span><\/span><\/li>\n
    4. Myopia<\/span><\/span> (nearsightedness)<\/span><\/span><\/li>\n
    5. Thin central cornea<\/span><\/span> (<555 \u00b5m on pachymetry)<\/span><\/span><\/li>\n
    6. Elevated IOP<\/span><\/span> (>21 mmHg, though normal-tension glaucoma occurs with IOP \u226421)<\/span><\/span><\/li>\n<\/ol>\n<\/li>\n<\/ul>\n
      \n
