Does Wuhan Aier Eye Hospital need an empty stomach?
Wuhan Aier Eye Hospital is a professional ophthalmic medical institution in Wuhan, committed to providing comprehensive ophthalmic services. Before the examination, many patients will have questions about whether it is necessary to carry out ophthalmic examination on an empty stomach? The following will be elaborated from several aspects.
Check item type
First, it is necessary to determine whether an empty stomach is required according to the type of inspection items. In ophthalmic examination, some common items include vision examination, fundus examination, optometry, intraocular pressure examination, etc. Among them, vision examination and optometry examination do not need an empty stomach, because these examinations mainly evaluate the function and structure of the eyes, and do not involve the detection of blood indicators. However, fundus examination and intraocular pressure examination may require pupil dilation. At this time, patients are generally advised to have an empty stomach to avoid pupil contraction caused by food intake, which affects the accuracy of the examination results.
It should be noted that the specific examination requirements may vary from hospital to hospital or doctor. Therefore, it is better to consult the hospital or doctor in advance to understand the specific examination preparations before eye examination.
Inspection schedule
Secondly, the inspection schedule should also be considered. The function of the human digestive system varies at different times of the day. Generally speaking, the fasting state before the morning examination is more ideal for some examinations that need blood testing, such as fundus examination. This is because when the stomach is empty in the morning, there is no food intake in the gastrointestinal tract, and the content of gastric acid and gastric juice in the blood is low, which can avoid affecting the accuracy of blood indicators due to food intake.
However, for other ophthalmic examination items that do not need blood test, an empty stomach is not necessary. For example, vision examination and optometry only need to assess the visual function of the eyes, and there is no requirement for diet status. Therefore, when determining the examination time, in addition to considering the characteristics of the examination item itself, it is also necessary to carefully select the time period that will not affect the normal life rhythm of the patient.
Special needs before inspection
Some patients need ophthalmic examination due to special physical conditions, and there may be additional special needs for these patients. For example, diabetic patients may need to have a hemoglobin A1c test, which is mainly used to assess the patient's long-term blood sugar control. For patients who have undergone glycosylated hemoglobin examination, an empty stomach of more than 8 hours is generally required to ensure that the glycosylated hemoglobin level measured in the blood accurately reflects the long-term blood sugar control level of patients.
In addition, some patients may receive drug treatment or often eat and supplement drugs in the morning. At this time, they also need to inform the doctor about the situation so that the doctor can choose the most appropriate time and method of examination.
Summary
To sum up, in the ophthalmic examination of Wuhan Aier Eye Hospital, fasting requirements are closely related to the type of examination items, examination schedule and special needs. In general, vision examination and optometry do not need an empty stomach, while fundus examination and intraocular pressure examination may need an empty stomach. In addition, patients with special needs may have additional fasting requirements or special schedules. Therefore, it is better to consult the hospital or doctor in advance to understand the relevant requirements before the ophthalmic examination, so as to be ready for the examination.
