Jane, diagnosed with diabetes 10 years ago, develops visual impairment, primarily because of:
Microvascular changes in the eye
Development of exophthalmos
Abnormal metabolism in the lens
Cataract development
The Correct Answer is A
A. Diabetic retinopathy, a common complication of diabetes, is caused by microvascular changes in the eye. Chronic high blood sugar can damage the small blood vessels in the retina, leading to visual impairment. This is the most common cause of visual impairment in people with long-standing diabetes.
B. Exophthalmos is typically associated with thyroid disorders, particularly Graves' disease, not diabetes.
C. Abnormal metabolism in the lens can lead to cataracts, but it is not the primary cause of visual impairment in diabetic patients.
D. Cataracts are more common in people with diabetes, but they are not the primary cause of visual impairment in diabetes. Diabetic retinopathy due to microvascular damage is the leading cause.

Correct Answer is A
Explanation
A. The presence of epithelial cells in urinary casts is indicative of acute tubular necrosis (ATN), a condition where the tubular cells in the kidneys are damaged, often due to ischemia or nephrotoxic substances. These damaged cells shed into the urine, forming casts.
B. Glomerulonephritis is characterized by inflammation of the glomeruli and typically leads to hematuria and proteinuria, but it is not specifically associated with epithelial cells in casts.
C. Urinary tract infections (UTIs) usually cause bacteriuria, pyuria, and sometimes hematuria, but not epithelial cell casts.
D. Pyelonephritis is an infection of the kidneys that can cause white blood cell casts and bacteria in the urine, but it is not typically associated with epithelial cell casts.
