In order to better cooperate with the doctor, so that the doctor can clearly understand the condition as soon as possible, more convenient to find lesions, clear diagnosis, the characteristics of the disease suffered by each department is different, the things that patients should pay attention to also varies from person to person and from disease to disease, so what are the precautions that ophthalmology patients take when they come to see the doctor? (1) No makeup. This is especially true for eyelid diseases (mydriasis, blepharitis, keratitis, dry eye, etc.). Young female patients often wear eye shadow and eyeliner, which can conceal the skin of the eyelids from the extent of the disease such as congestion and edema, and can prevent the doctor from examining them, such as turning over the eyelids and staining the cornea for examination, and cosmetics can lose color and contaminate, causing unnecessary damage. (2) No contact lenses. Contact lenses cover the surface of the cornea, and during the examination, the epithelial condition of the cornea cannot be seen, and sometimes fluorescein staining is required, and once the contact lenses are stained by corneal stain, it is impossible to remove them. (3) When waiting for a consultation, vision check should be the first thing to be done. The greatest hope of ophthalmology patients is that the eye disease will not affect their vision or that their vision will improve after treatment, so visual acuity is the most important examination indicator for ophthalmologists. Vision examinations are divided into: distance vision, near vision, with the former looking at a large vision chart and the latter looking at a small, reading distance vision chart. Some diseases affect near vision and distance vision differently, so vision should be checked at every visit. (4) At the doctor’s request, dilate the pupil to check the fundus of the eye. The pupil is a portal through which light enters the eye. The pupil is normally 2.5-4 mm in diameter and is sensitive to the light reflex collar, and when light is strong, the pupil narrows. If the lesion is located behind the pupil, such as the lens (that is, when examining cataracts), and the vitreous, retina and other structures, such a small pupil will not be visible to the doctor, so if the doctor asks for a dilated pupil for cataracts and fundus diseases, the patient had better follow the Do what the doctor asks. (5) Truthfully inform the doctor of your identity and do not use someone else’s visit card, and medical record book. Some patients use other people’s visit cards and medical records to save money. This is not conducive to the doctor’s understanding of the condition because, depending on the age and occupation, the type and cause of the disease under consideration may vary, and concealing the true situation can affect the doctor’s quick judgment and delay the diagnosis. (6) When consulting online, be sure to introduce the patient’s gender, age, and past medical history first. Patients who consult through the Internet are always anxious to introduce their symptoms and forget to tell the doctor the patient’s gender, age, whether they are nearsighted, and whether they have had other eye, or systemic diseases, all of which are important factors to help the doctor make a diagnosis, especially, since the doctor cannot see the patient’s eyes clearly and directly during an Internet consultation.
