Do you need an empty stomach for eye examination?
Eye examination is a very common medical examination, which can help doctors understand the health of our eyes. Before an eye exam, some people may wonder whether they need an empty stomach. The following is a detailed description of whether an empty stomach is required for ophthalmic examination from several aspects.
Doctor's advice
First, we can pay attention to the doctor's advice. Generally speaking, when the doctor instructs us to carry out eye examinations, he will tell us whether we need an empty stomach. This is because different eye examinations may require different preparations. For example, if we need to have a pupil dilation test, the doctor may recommend us to have an empty stomach, because this test may cause dizziness and nausea. However, if only routine vision or intraocular pressure tests are performed, an empty stomach is usually not required.
Similarly, different hospitals and doctors may have different views. Some hospitals may require an empty stomach for ophthalmic examination, because they hope to observe the condition of the eyes more accurately during the examination. Other hospitals may not require an empty stomach, because they believe that empty stomach has nothing to do with the examination results.
Characteristics of inspection items
Secondly, we can consider the specific items of eye examination. Different ophthalmic examination items have different requirements on whether an empty stomach is needed. For example, fundus examination usually requires eyes to relax, so it is recommended that we do not eat too much food before the examination, so as not to affect the effect of the examination. However, corneal topography is not affected by diet, so fasting is not required.
In addition, there are some special ophthalmic examination items, such as optometry and visual field examination. These examinations usually do not require an empty stomach, but we may need to wear or insert some special instruments in advance so that doctors can better observe the eyes. Therefore, we need to consult the doctor about whether we need an empty stomach before carrying out these examinations.
Precautions before inspection
In addition to whether we need an empty stomach, we should also pay attention to some other matters before examination. First of all, we need to make an appointment for an eye examination in advance to ensure that we can see the doctor on time. Secondly, we should try to keep enough sleep so that our eyes can relax during the examination. In addition, we should also avoid wearing contact lenses or colored contact lenses to avoid affecting the examination results.
Finally, we should also check the specific requirements of the hospital. Take a well-known ophthalmic hospital in Guangzhou as an example. The routine ophthalmic examination they provide does not require an empty stomach. However, if we need to carry out some special examinations, such as fundus examination or pupil dilation examination, we may need an empty stomach. Therefore, we'd better consult the relevant information of the hospital or the doctor before the ophthalmic examination to understand the specific preparations.
Summary
To sum up, whether an empty stomach is required for ophthalmic examination mainly depends on the doctor's suggestions and specific examination items. Different hospitals and doctors may have different views, so we'd better consult a doctor before conducting eye examinations. In addition, we should also pay attention to other pre inspection matters to ensure the accuracy and smooth progress of the inspection.
