A patient is complaining of a black large spot in the center of their vision.
The nurse determines this manifestation as central vision loss.
Which eye disorder below is consistent with this symptom?
Glaucoma.
Detached retina.
Macular degeneration.
Diabetic retinopathy.
The Correct Answer is C
Choice A rationale
Glaucoma is characterized by increased intraocular pressure that can lead to optic nerve damage and peripheral vision loss. It does not typically cause central vision loss or the presence of a large black spot in the center of vision.
Choice B rationale
A detached retina often causes the sudden appearance of floaters or flashes of light, and a shadow or curtain effect in the peripheral vision. It does not typically present as a black spot in the center of vision.
Choice C rationale
Macular degeneration is an age-related condition that affects the central part of the retina (macula). It leads to central vision loss, which can manifest as a black or dark spot in the center of vision. This condition progressively impairs the ability to see fine details and perform activities like reading or recognizing faces.
Choice D rationale
Diabetic retinopathy is a complication of diabetes that affects the blood vessels in the retina. It can cause vision changes, such as floaters or blurred vision, but it does not typically present as a large black spot in the center of vision.
