1. Why should vision be checked first when visiting an eye doctor? One of the main symptoms of eye disease is decreased vision. Vision examination is an important basis for discovering eye diseases and making a diagnosis.

2. Why is a slit lamp examination necessary when visiting an ophthalmologist? A slit lamp examination can clearly observe the eyelids, conjunctiva, sclera, cornea, anterior chamber, iris, pupil, lens and the anterior 1/3 of the vitreous body, and can determine the location, nature, size and depth of the lesion. Therefore, slit lamp examination is an essential and important part of ophthalmic examination.

3. Why do we need to check the fundus when visiting an ophthalmologist? The eyes are closely related to various organs of the body, and the occurrence of many diseases can often be reflected in the fundus. Doctors can use an ophthalmoscope to see the vitreous body, retina, optic nerve head, and retinal arteries and veins. They can detect any abnormalities from the changes in the retinal structure, morphology, and blood vessels, and thus infer what disease the patient has. Fundus examination is not only important for the diagnosis of ophthalmic diseases, but also can detect different fundus manifestations, and make diagnoses or provide clues for certain systemic diseases, especially internal medicine and neurological diseases.

4. Why do we need to measure intraocular pressure when visiting an ophthalmologist? Among the blind population at home and abroad, about 10-15% are caused by glaucoma, and about 2% of adults over 40 years old suffer from glaucoma. Glaucoma is caused by excessive intraocular pressure, which causes damage and atrophy of the optic nerve, resulting in various visual impairments and visual field defects. Checking intraocular pressure is one of the three important tests for detecting glaucoma and it is also the simplest test. Therefore, patients seeking medical attention should undergo an intraocular pressure test to rule out the possibility of high intraocular pressure and glaucoma, in order to detect and treat them early.
