Chapter 9: Problem 176

A client has just been diagnosed with closed-angle (narrow-angle or acute angle-closure) glaucoma. The nurse assesses the client for which of the following most common presenting symptoms of this disorder? 1\. halo vision 2\. dull eye pain 3\. severe eye and face pain 4\. impaired night vision

Short Answer

Expert verified
The most common presenting symptom of closed-angle glaucoma is severe eye and face pain.

Step by step solution

01

Understanding Closed-Angle Glaucoma

Closed-angle glaucoma is a condition where there is a sudden increase in eye pressure due to a blocked drainage canal. It is an acute condition that requires immediate medical attention.
02

Reviewing Symptoms of Closed-Angle Glaucoma

Closed-angle glaucoma commonly presents with symptoms related to high intraocular pressure, such as severe eye pain, headache, nausea, and vomiting. Visual disturbances like seeing halos around lights can also occur.
03

Evaluating the Options

From the given symptoms: halo vision, dull eye pain, severe eye and face pain, and impaired night vision, we need to determine which is most commonly associated with closed-angle glaucoma.
04

Identifying the Most Common Presenting Symptom

Severe eye and face pain is the most common presenting symptom for closed-angle glaucoma, since the rapid rise in eye pressure causes intense pain.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Acute Angle-Closure Glaucoma
Acute angle-closure glaucoma is a serious eye condition that happens when the drainage angle for the eye鈥檚 fluids becomes suddenly blocked. This blockage causes a rapid increase in the intraocular pressure within the eye, leading to a host of uncomfortable and serious symptoms. Because the increase in pressure occurs swiftly, it classifies this type of glaucoma as 'acute.'

The primary concern with acute angle-closure glaucoma is the speed at which it can cause damage to the optic nerve, possibly leading to permanent loss of vision if not treated promptly. Therefore, this condition requires emergency medical intervention.
Intraocular Pressure
Intraocular pressure (IOP) refers to the fluid pressure inside the eye. It is a crucial factor in maintaining the eye's shape and ensuring proper vision function. In most healthy eyes, a delicate balance exists between the production and drainage of this aqueous humor fluid. However, in cases of acute angle-closure glaucoma, this balance is disturbed.

When the drainage canal gets blocked, it prevents fluid from leaving the eye. This causes the intraocular pressure to skyrocket suddenly and dramatically. Elevated IOP is risky because it can damage the optic nerve, which acts like a communication cable carrying visual information from the eye to the brain.
Eye Pain Assessment
Eye pain assessment is a critical component when diagnosing acute angle-closure glaucoma. Patients often report severe eye and face pain, which is the most telling symptom of this condition. Pain can be accompanied by other symptoms such as headache, nausea, and vomiting. Assessing the types of pain and its duration helps health professionals determine the severity of the condition.

The assessment involves asking specific questions to understand the intensity and location of the pain, such as:
  • Is the pain constant or does it come and go?
  • Is it sharp, dull, or throbbing?
  • Does it affect one eye or both?
These questions can guide the healthcare provider to a more accurate diagnosis and help in developing an appropriate treatment plan.
Nursing Diagnosis
In the management of acute angle-closure glaucoma, a nursing diagnosis is essential for tailoring the care plan to meet the individual needs of the patient. A nursing diagnosis for this condition often includes statements such as, 'acute pain related to increased intraocular pressure.' This helps direct nurses to prioritize pain management and monitoring changes in the patient's vision.

Nurses play a vital role in not only assessing symptoms but also providing interventions to alleviate discomfort. They educate patients on symptoms to watch for and assist in procedural preparations, should surgical intervention be needed to relieve the pressure.
Visual Disturbances
Visual disturbances in acute angle-closure glaucoma might manifest as seeing halos around lights, blurred vision, or reduced peripheral vision. These disturbances are due to the sudden change in intraocular pressure which affects how light is focused in the eye.

Symptoms like halos around lights can particularly signal that the pressure is reaching dangerous levels. Visual disturbances are often one of the first signs that prompt patients to seek medical attention. Recognition and prompt treatment of these symptoms are crucial to preventing lasting vision impairment.

A client with a diagnosis of obsessive compulsive disorder goes to a mental health center when the symptoms worsen. The client received counseling one year ago and has been maintained on medication.
