One of the prominent symptoms of dry beriberi, which is a result of thiamine (vitamin B1) deficiency, is peripheral neuropathy. This condition is characterized by damage to the peripheral nerves, leading to sensations of tingling, numbness, and weakness, particularly in the extremities. Thiamine plays an essential role in energy metabolism and nerve function, and its deficiency can lead to disruption of nerve fibers, leading to these neuropathic symptoms.

In contrast, ophthalmoplegia is more commonly associated with Wernicke's encephalopathy, a condition linked to thiamine deficiency but not specifically a symptom of dry beriberi. Heart failure is more characteristic of wet beriberi, another form of beriberi caused by thiamine deficiency that affects the cardiovascular system. Scaly red papules are not associated with beriberi but rather can be seen in conditions like pellagra, which is associated with niacin deficiency. Therefore, peripheral neuropathy is the symptom directly correlated with dry beriberi due to thiamine deficiency.
