INTRODUCTION
Glaucoma is a group of eye conditions that damage the optic
nerve, the health of which is vital for good vision. This damage
is often caused by an abnormally high pressure in eye.
Glaucoma is one of the leading causes of blindness for people
over the age of 60. It can occur at any age but is more common
in older adults.
Many forms of glaucoma have no warning signs. The effect is so
gradual that you may not notice a change in vision until the
condition is at an advanced stage.
DEFINITION
• Glaucoma is a group of eye diseases characterized by
damage to the optic nerve usually due to excessively
high intraocular pressure (IOP).This increased
pressure within the eye, if untreated can lead to optic
nerve damage resulting in progressive, permanent
vision loss, starting with unnoticeable blind spots at
the edges of the field of vision, progressing to tunnel
vision, and then to blindness.
ETIOLOGY
ETIOLOGY
Congenital genetic malformation
Diabetic retinopathy
Occular trauma
Corticosteroids
RISK FACTORS
NORMAL PHYSIOLOGY
• 90% of fluid flows out of the anterior
chamber draining through the spongy
trabecular meshwork.
• Canal of schelm and the episcleral
veins.
• 10% of the fluid exist through the
ciliary body into the suprachoroidal
space.
• Venous circulation of ciliary body,
choroid and sclera.

NURSES RESPONSIBILITY
• Provide information regarding management of glaucoma
• Discuss preoperative and postoperative teaching for
immediate surgical opening of the eye chamber.
• Prepare to administer carbonic anhydrase inhibitors IV or
IM, to restrict production of aqueous humor.
• Prepare to administer osmotic agents.
• Discuss and prepare the client for surgical or laser
peripheral iridectomy after the acute episode is relieved.
NURSES RESPONSIBILTY
• Provide information about laser trabeculoplasty, if medication therapy
proves ineffective.
• Teach the client about specific safety precautions.
• Instruct the client to avoid mydriatics such as atropine, which may
precipitate acute glaucoma in a client with closed-angle glaucoma.
• Instruct the client to carry prescribed medications at all times.
• Instruct the client to carry a medical identification card or wear a
bracelet stating his type of glaucoma and need for medication.
• Instruct the client to take extra precautions at night (e.g. use of
handrails, provide extra lighting to compensate for impaired pupil
dilation from miotic use).
PREVENTION
• Get regular dilated eye examinations. Regular comprehensive eye exams can help
detect glaucoma in its early stages, before significant damage occurs.
• Know your family's eye health history. Glaucoma tends to run in families.
• Exercise safely. Regular, moderate exercise may help prevent glaucoma by
reducing eye pressure.
• Take prescribed eyedrops regularly. Glaucoma eyedrops can significantly reduce
the risk that high eye pressure will progress to glaucoma.
• Wear eye protection. Serious eye injuries can lead to glaucoma. Wear eye
protection when using power tools or playing high-speed racket sports in enclosed
courts.
DIET PLANNING
1. Sea Food
2. Leafy Greens
3. Eggplant
4. Goji Berries
5. Blackcurrant
6. Peaches and Oranges
7. Drinkable

  • 3. INTRODUCTION Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. This damage is often caused by an abnormally high pressure in eye. Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults. Many forms of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is at an advanced stage.

  • 5. DEFINITION • Glaucoma is a group of eye diseases characterized by damage to the optic nerve usually due to excessively high intraocular pressure (IOP).This increased pressure within the eye, if untreated can lead to optic nerve damage resulting in progressive, permanent vision loss, starting with unnoticeable blind spots at the edges of the field of vision, progressing to tunnel vision, and then to blindness.
  • 7. ETIOLOGY Congenital genetic malformation Diabetic retinopathy Occular trauma Corticosteroids
  • 9. NORMAL PHYSIOLOGY • 90% of fluid flows out of the anterior chamber draining through the spongy trabecular meshwork. • Canal of schelm and the episcleral veins. • 10% of the fluid exist through the ciliary body into the suprachoroidal space. • Venous circulation of ciliary body, choroid and sclera.
  • 10. STAGES Initiating event Structural alteration in aqueous outflow system Functional alteration (increased IOP and impaired blood flow ) Optic nerve damage Visual loss

  • 43. NURSES RESPONSIBILITY • Provide information regarding management of glaucoma • Discuss preoperative and postoperative teaching for immediate surgical opening of the eye chamber. • Prepare to administer carbonic anhydrase inhibitors IV or IM, to restrict production of aqueous humor. • Prepare to administer osmotic agents. • Discuss and prepare the client for surgical or laser peripheral iridectomy after the acute episode is relieved.
  • 44. NURSES RESPONSIBILTY • Provide information about laser trabeculoplasty, if medication therapy proves ineffective. • Teach the client about specific safety precautions. • Instruct the client to avoid mydriatics such as atropine, which may precipitate acute glaucoma in a client with closed-angle glaucoma. • Instruct the client to carry prescribed medications at all times. • Instruct the client to carry a medical identification card or wear a bracelet stating his type of glaucoma and need for medication. • Instruct the client to take extra precautions at night (e.g. use of handrails, provide extra lighting to compensate for impaired pupil dilation from miotic use).
  • 45. PREVENTION • Get regular dilated eye examinations. Regular comprehensive eye exams can help detect glaucoma in its early stages, before significant damage occurs. • Know your family's eye health history. Glaucoma tends to run in families. • Exercise safely. Regular, moderate exercise may help prevent glaucoma by reducing eye pressure. • Take prescribed eyedrops regularly. Glaucoma eyedrops can significantly reduce the risk that high eye pressure will progress to glaucoma. • Wear eye protection. Serious eye injuries can lead to glaucoma. Wear eye protection when using power tools or playing high-speed racket sports in enclosed courts.
