Which of the following is NOT a common cause of low vision?

• A. Macular degeneration
• B. Diabetic retinopathy
• C. Hypertension
• D. Cataracts

Answer: (C)

Low vision refers to a visual impairment that cannot be corrected with standard glasses, contact lenses, medication, or surgery, and is often caused by various eye diseases. Macular degeneration, diabetic retinopathy, and cataracts are all well-established conditions that can significantly affect vision and lead to low vision. Macular degeneration is a leading cause of vision loss particularly in older adults, affecting the central part of the retina and impairing sharp, central vision. Diabetic retinopathy is a complication of diabetes that affects the blood vessels in the retina, leading to vision problems. Cataracts cause clouding of the lens, which can lead to blurred vision and, if untreated, eventual blindness. Hypertension, while it can affect the eyes, primarily does so indirectly by contributing to other issues, such as retinal damage or hypertensive retinopathy. However, hypertension itself is not a direct cause of low vision. It often requires other factors or conditions to jeopardize eyesight significantly. Thus, it's the least associated with low vision among the options presented.
