Correct Answer is A

Explanation

A. Macular degeneration: This is a leading cause of vision loss in older adults and typically results in the loss of central vision, making it difficult to read or recognize faces.
B. Diabetic retinopathy: This condition affects the retina but typically causes changes in peripheral vision or blurry vision, not a specific loss of central vision.
C. Glaucoma: Glaucoma often leads to peripheral vision loss, not central vision loss.
D. Cataracts: Cataracts cause cloudy or blurry vision, but not a specific decrease in central vision.

A. Asymmetry of the lesions B. Red and black coloration C. Flat D. 8 mm in diameter E. Round edges

Correct Answer is ["A","B","D"]

Explanation

A. A lesion that is asymmetrical is concerning, as melanoma and other skin cancers tend to be irregular in shape. This is an important warning sign.
B. Red and black coloration in a lesion is concerning because it can indicate changes in blood flow or necrosis, both of which are suspicious for malignancy.
C. A flat lesion does not automatically indicate a problem, as many benign lesions, like moles, can be flat. The texture or elevation of the lesion is not always a concern unless there are other risk factors.
D. A lesion larger than 6 mm is concerning, especially if it is changing in size or shape. Larger lesions should be evaluated by a healthcare provider for potential malignancy.
E. Round edges are typically a characteristic of benign lesions, so this is not as concerning unless there are other warning signs present.
