Fever with congestion of the eyes is a disease that causes an increase in body temperature with congestion of the eyes, which is seen in more serious infections such as hemorrhagic fever, drug rash, acute hemorrhagic conjunctivitis, upper respiratory tract infections. The diagnosis of fever with bloodshot eyes is based on the characteristics of the symptoms. This situation is mainly to look at the fundus of the eye and the surface of the eye, and at the same time check the temperature of the body to clarify the height of the fever, check the blood routine, to clarify the cause of the fever, if not clear, then it is necessary to do further examination. 1, corneal photographic method corneal photographic method is one of the methods for the treatment of exposure keratitis, exposure keratitis (exposure keratitis) is common in eyelid closure incomplete various lesions, resulting in corneal exposure and transient movement disorders, tears can not wet the cornea and corneal epithelial damage occurs. 2, urine routine urine analyzer is also known as dry chemical urine analyzer. The instrument is easy to operate and fast (the fastest 10s can complete the detection of 11 kinds of urine components). Pulse The pulse test is an auxiliary test used to check whether the pulse is normal or not. Pulse is the beat of an artery. The pressure change caused by the heartbeat vibrates the wall of the aorta, which is transmitted along the wall of the artery to the periphery, resulting in a pulse. The pulse is often referred to as the pulse felt on the radial side of the wrist. The pulse can also be recorded with a pulse meter. The pulse reflects the functional status of the circulatory system. The content of the pulse examination includes checking the rate, rhythm, tension, strength, waveform and the condition of the arterial wall. Through this examination, we can determine the location of the lesion and the corresponding signs of disease. 4. Blood pressure: Blood pressure in lying, sitting or standing position is an auxiliary test for checking whether the blood pressure is normal or not. Most doctors measure the patient’s blood pressure in the sitting position or the lying position during the visit to the doctor. If the patient’s blood pressure is measured only in the lying position, there is a possibility that high blood pressure may be measured, which may lead to a long-term misdiagnosis of low blood pressure. Especially the blood pressure of middle-aged and old people should be paid special attention to, with the increase of age, the aging process of human body is accompanied by the decrease of response to pressure reflexes, the decrease of vascular compliance and the attenuation of vestibular sympathetic reflexes, so the incidence of postural hypotension increases significantly, and the incidence of postural hypertension also increases, and the site of the lesion and the corresponding signs of disease can be determined through this examination. 5. Blood routine Blood routine is the most general and basic blood test. Blood consists of two major parts: liquid and tangible cells, and the routine blood test is for the cellular part of blood. Blood has three kinds of cells with different functions – red blood cells (commonly known as erythrocytes), white blood cells (commonly known as leukocytes) and platelets. By observing the changes in number and morphological distribution, it is possible to determine the disease. It is one of the common auxiliary tests used by doctors to diagnose medical conditions.
