The symptoms of binocular upward gaze can be seen in epileptic-like seizures of hypoglycemia, mainly manifested as a shallow comatose state with moist, cyanotic skin, foaming at the corners of the mouth, binocular upward gaze, loss of light reflex in both pupils, neck tonicity, coarse breath sounds in both lungs, and strong heart sounds. How is upward gaze diagnosed? Perform a rapid glucose measurement in patients with unexplained impairment of consciousness (or epilepsy). If there is abnormal hypoglycemia, glucose should be pushed immediately For those with episodic (especially in fasting) psycho-neurological abnormalities, convulsions, behavioral abnormalities, impaired consciousness or coma, especially for diabetic patients treated with insulin or oral hypoglycemic drugs, the possibility of hypoglycemia should be considered and blood glucose should be checked promptly. It is worth noting that some patients with hypoglycemia have normal blood glucose and no hypoglycemic symptoms at the time of consultation, and often only show the sequelae of chronic hypoglycemia, such as hemiplegia, dementia, epilepsy, mental disorder, and obvious low IQ in children. Attention should also be paid to the differential diagnosis with other diseases. 1. Crowding phenomenon in amblyopic eyes: One of the signs of amblyopic eyes is that the recognition ability of individual fonts is much higher than that of fonts of the same size but arranged in rows, and this phenomenon is called crowding phenomenon. 2, retinal fissure: retinal fissure is a full-layer split in the retina, just like a tear in a garment. Generally, it is due to a degenerative area of the retina, and the fissure is formed due to the pulling of the vitreous. The formation of retinal fissures is the result of the combined effect of both retinal and vitreous tissue degeneration. It is more common in middle-aged and elderly people, especially in patients with high myopia, because of the degeneration of the vitreous and retina in the elderly or highly myopic patients.
