Which finding on a fundoscopic exam is a potential sign of uncontrolled diabetes?

The presence of exudates or hemorrhages on a fundoscopic exam can indicate a potential complication of uncontrolled diabetes, specifically diabetic retinopathy. When blood sugar levels are persistently elevated, it can lead to damage of the retinal blood vessels. This damage may result in the formation of microaneurysms, which can leak fluid and lead to the accumulation of exudates in the retinal tissue. These exudates typically appear as cotton wool spots or hard and soft exudates, and the presence of retinal hemorrhages further signifies vascular damage.

In contrast, other findings such as retinal detachment and hyperemia of the disc, while they may present in various conditions, are not directly associated with uncontrolled diabetes itself. A normal retinal appearance, on the other hand, would suggest that there are no indications of diabetic complications, which is contrary to the question concerning potential signs of uncontrolled diabetes. Thus, identifying exudates or hemorrhages is key in diagnosing and monitoring the effects of diabetes on the eyes.
