A client with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?
A.
Until a smaller angle can be restored.
B.
For long-term control of normal eye pressure.
C.
Until the excess pressure is reduced.
D.
For long-term control of pain and swelling.
The Correct Answer and Explanation is:
The correct answer is B. For long-term control of normal eye pressure.
Explanation:
Open-angle glaucoma is a chronic condition characterized by increased intraocular pressure (IOP) due to impaired drainage of aqueous humor from the eye. This elevated pressure can damage the optic nerve over time, leading to vision loss if left untreated. The primary goal of treatment for open-angle glaucoma is to reduce and manage this elevated IOP to prevent further optic nerve damage and preserve vision.
Eye drops are a common and effective treatment for managing open-angle glaucoma. These medications work in various ways to reduce intraocular pressure: some decrease the production of aqueous humor, while others improve its drainage. For instance, medications such as beta-blockers (e.g., timolol), prostaglandin analogs (e.g., latanoprost), and carbonic anhydrase inhibitors (e.g., dorzolamide) are frequently used in the treatment regimen.
The use of eye drops for open-angle glaucoma is typically long-term. Unlike some other medical treatments that are used for short-term conditions or until a specific problem is resolved, the treatment of open-angle glaucoma requires ongoing management. The medication is prescribed for long-term control of normal eye pressure, rather than a temporary solution. This is because the condition is chronic and progressive, and maintaining controlled IOP is crucial to prevent the progression of optic nerve damage.
Therefore, informing the client that the prescribed eye drops are needed “for long-term control of normal eye pressure” is accurate. This response aligns with the understanding that open-angle glaucoma requires continuous management to control IOP and protect the client’s vision over time. Discontinuing the medication without medical guidance could result in an increase in IOP and subsequent damage to the optic nerve, leading to potential vision loss.
