A 70-year-old patient presents with complaints of visual disturbances. Upon assessment, the patient reports experiencing difficulty reading, seeing faces clearly, and needing more light when performing tasks. What is the most likely clinical manifestation of macular degeneration?
Night blindness
Central vision loss
Peripheral vision loss
Double vision
The Correct Answer is B
Choice A Reason:
Night blindness, or difficulty seeing in low light, is not a primary symptom of macular degeneration. This condition primarily affects the macula, the central part of the retina responsible for sharp, central vision. Night blindness is more commonly associated with conditions like retinitis pigmentosa or vitamin A deficiency.
Choice B Reason:
Central vision loss is the hallmark of macular degeneration. This condition leads to the deterioration of the macula, causing blurred or lost central vision while peripheral vision remains intact. Patients often report difficulty reading, recognizing faces, and performing tasks that require fine visual detail3.
Choice C Reason:
Peripheral vision loss is not typically associated with macular degeneration. This condition affects the central part of the retina, leaving peripheral vision largely unaffected. Peripheral vision loss is more commonly seen in conditions like glaucoma.
Choice D Reason:
Double vision, or diplopia, is not a characteristic symptom of macular degeneration. This condition affects the clarity of central vision but does not typically cause double vision. Double vision can result from issues with the eye muscles or nerves, such as in cases of strabismus or cranial nerve palsies.

Correct Answer is C
Explanation
Choice A Reason:
The statement “If I forget to take my eye drops, I should wait until the next time they are due” is incorrect. For chronic open-angle glaucoma, it is important to take eye drops as prescribed to maintain consistent intraocular pressure control. If a dose is missed, the patient should take it as soon as they remember, unless it is almost time for the next dose. Skipping doses can lead to fluctuations in eye pressure, which can worsen the condition.
Choice B Reason:
The statement “Every two years I will need to have my vision checked by an eye doctor” is not accurate. Patients with chronic open-angle glaucoma typically need more frequent monitoring, often every 3 to 6 months, depending on the severity of the condition and the stability of their intraocular pressure. Regular check-ups are crucial for adjusting treatment and preventing vision loss.
Choice C Reason:
The statement “I should call the clinic before taking any over-the-counter medications” indicates an understanding of the teaching. Some over-the-counter medications can affect intraocular pressure or interact with glaucoma medications. Consulting with a healthcare provider before taking new medications helps ensure that they do not interfere with glaucoma management.
Choice D Reason:
The statement “When my vision improves, I will be able to stop taking the eye drops” is incorrect. Glaucoma is a chronic condition that requires ongoing treatment to manage intraocular pressure and prevent further damage to the optic nerve. Stopping medication can lead to a rapid increase in eye pressure and potential vision loss.
Correct Answer is A
Explanation
Choice A Reason:
Storing hearing aids in a dry, cool place when not in use is crucial for maintaining their functionality and longevity. Moisture and heat can damage the delicate electronic components of hearing aids. Using a dehumidifier specifically designed for hearing aids can help prevent moisture buildup and extend the life of the devices.
Choice B Reason:
Using cotton swabs to clean the interior components of the hearing aid is not recommended. Cotton swabs can push debris further into the hearing aid and potentially damage the internal components. Instead, specialized cleaning tools such as wax loops, brushes, and earmold tubing blowers should be used to clean hearing aids properly.
Choice C Reason:
It is not okay to wear hearing aids while showering or swimming. Most hearing aids are water-resistant but not waterproof. Exposure to water can damage the hearing aids and affect their performance. It is important to remove hearing aids before any activities involving water.
Choice D Reason:
Replacing the batteries of hearing aids once a month regardless of usage is not necessary. Battery life depends on the type of hearing aid, the battery size, and the amount of usage. It is more practical to replace the batteries when they are low or depleted, as indicated by the hearing aid’s low battery warning.
