If there is any discomfort or disease in the eyes, the first thing you need to do is to go to the hospital for a preliminary examination to understand the possible direction of the disease. Routine examination mainly includes the following six items: first, visual acuity examination, which is the most important examination, through which we can understand whether the eye vision is damaged; second, intraocular pressure examination, to clarify whether there is a disease such as glaucoma; third, optometry examination, to clarify whether there is refractive error or amblyopia and other diseases; fourth, fundus examination, through which we can understand whether there is a disease of the fundus; fifth, slit lamp examination, which is a very routine examination of the eye, can be a detailed examination of the anterior segment of the eye, including the cornea, conjunctiva, lens; sixth, eye position examination, through this examination can understand whether the eye has strabismus. The above routine examinations can basically make a preliminary judgment on eye diseases.
