Otolithiasis is diagnosed primarily on the basis of the patient’s clinical presentation, changes in body position that trigger vertigo, and the onset or worsening of nystagmus.
Otolith is another name for benign paroxysmal positional vertigo, and the diagnosis relies primarily on history and positional examination. CLINICAL SYMPTOMS: The primary history is transient rotation on rising, turning, lifting and stooping, and in severe cases nausea and vomiting.
At present, the commonly used instrument for this disease is video nystagmography, which is based on the principle of infrared camera and utilizes digital video to record the nystagmus characteristics, intensity, direction, amplitude and the entire onset of the whole process under different positions. After the test, the data and images can be stored, and finally the computer is applied to analyze the parameters of the eyeball and its movement trajectory to ensure the accuracy of the diagnosis.
This instrument can record the results objectively, judge the torsional and rotational nystagmus, significantly increase the detection rate of induced nystagmus, accurately locate the affected semicircular canals, and provide an important basis for the implementation of appropriate clinical treatment.
Therefore, with the development of medicine, video nystagmography has been gradually applied to the diagnosis of otolithiasis, which helps to improve the accuracy of the diagnosis of the disease.
