Glaucoma

Glaucoma

1. increase of IOP (>20mmHG) by excessive accumilation of aqueous humor

   • normal IOP: 10-20mmHG

2. Two types of Glaucoma

   • Acute (close/narrow angle)
     • acute/ SUDDEN marked increase in IOP
       • etiology: aging, trauma, infection, drugs
         • - Patient will feel heaviness in eyes -eye pain, N/V, headache
   • Chronic (open angle)
     • insidious (gradual) onset
       • etiology: aging in peoples >50 years
         • SIGNS AND SYMPTOMS
           • early signs:
             • increase IOP, blurred vision
           • late signs:
             • - peripheral vision loss - appearance of halos

3. 2nd leading cause of blindness

4. Diagnostic Tests

   • Tonometer: to measure IOP

5. RISK FACTORS:

   • family history of glaucoma, family history of diabetes, previous vision problems, medication use

6. NURSING IMPLICATIONS

   • ADMINISTER EYE DROPS AS PRESCRIBED
