A nurse at an ophthalmology clinic is providing medication teaching to a client who has open-angle glaucoma. Which of the following instructions should the nurse provide?
A.
Apply the medication when you are experiencing eye pain
B.
Use the medication only until the intraocular pressure returns to normal
C.
Use the medication for approximately 10 days, then gradually taper off
D.
Apply the medication on a regular schedule for the rest of your life
The Correct answer and Explanation is:
The correct answer is:
D. Apply the medication on a regular schedule for the rest of your life.
Explanation:
Open-angle glaucoma is a chronic condition characterized by increased intraocular pressure (IOP) due to a gradual blockage of the drainage canals in the eye. This condition is typically asymptomatic in the early stages, but if left untreated, it can lead to optic nerve damage and permanent vision loss. Therefore, managing IOP is crucial in preventing the progression of the disease.
The primary treatment for open-angle glaucoma involves the use of medications, such as eye drops, to lower IOP. These medications either decrease the production of aqueous humor or increase its outflow. However, these treatments do not cure glaucoma; they only help control it. Because open-angle glaucoma is a lifelong condition, continuous treatment is necessary to maintain safe IOP levels and prevent further damage to the optic nerve.
Option D emphasizes the importance of consistent, lifelong adherence to the prescribed treatment regimen. Regular application of the medication, as instructed by the healthcare provider, is essential to managing the condition effectively. Skipping doses or discontinuing treatment can result in elevated IOP, leading to irreversible optic nerve damage and vision loss.
Option A is incorrect because waiting until eye pain occurs is not advisable. Glaucoma often progresses without noticeable symptoms, so relying on pain as an indicator would be detrimental.
Option B is incorrect because stopping the medication once IOP normalizes can lead to a rebound increase in pressure, risking further optic nerve damage.
Option C is incorrect because tapering off the medication after 10 days is inappropriate. Open-angle glaucoma requires ongoing treatment, not a short-term intervention.
In summary, the key to managing open-angle glaucoma is adherence to a lifelong medication regimen to maintain optimal intraocular pressure and prevent vision loss.
