Nursing Care Plan for Glaucoma
Notes for Nursing Students
What is Glaucoma?
Glaucoma is a group of eye conditions that damage the optic nerve, often due to abnormally high pressure in the eye (intraocular pressure or IOP). This increased pressure results from inadequate drainage of aqueous humor from the anterior chamber of the eye. The damage to the optic nerve leads to progressive, irreversible vision loss and can result in permanent blindness if untreated.
Illustration of glaucoma’s effect on the eye
Pathophysiology of Glaucoma
The primary pathophysiological mechanism in glaucoma is elevated intraocular pressure (IOP) that causes mechanical stress on the lamina cribrosa of the optic nerve, leading to optic nerve damage. This results in the loss of retinal ganglion cells and their axons, which transmit visual information to the brain.
Pathophysiological process of glaucoma
- Obstruction of aqueous humor outflow
- Increased intraocular pressure
- Mechanical pressure on optic nerve
- Optic nerve damage and atrophy
- Progressive loss of visual field
- Eventual blindness if untreated
Types of Glaucoma
Comparison of different glaucoma types
1. Open-Angle Glaucoma (Primary Open-Angle Glaucoma)
- Most common type (90% of all cases)
- Develops slowly and painlessly
- Associated with diabetes and myopia
- Can develop in both eyes simultaneously
- Characterized by gradual loss of peripheral vision
2. Angle-Closure Glaucoma (Narrow-Angle Glaucoma)
- Less common but more severe form
- Can be acute (medical emergency) or chronic
- May be associated with eye trauma, inflammatory processes
- Characterized by sudden, excruciating pain, blurred vision, and ocular redness
- May lead to sudden blindness if not treated promptly
Open-angle glaucoma:
- Open drainage angle
- Painless
- Ensues gradually
- No acute symptoms
Closed-angle glaucoma:
- Closed drainage angle
- Lots of pain (acute form)
- Ocular redness
- Sudden onset
- Emergency treatment needed
