Guangzhou Shenzhen Ophthalmology Examination Project for High Myopia
Eye examination is an important step to help doctors understand patients' eye health. For patients with high myopia, ophthalmic examination is particularly important, which can help doctors determine the methods and programs for correcting myopia. The following will introduce the common items of Guangzhou and Shenzhen ophthalmology examination for high myopia.
1. Vision examination
Vision examination is one of the most basic items in ophthalmic examination. For patients with high myopia, vision examination can determine the need and degree of vision correction. Usually, a routine visual acuity chart is used. The patient needs to read the letters or patterns on the chart line by line with the left and right eyes. The doctor will record the minimum number of lines that can be read to evaluate the patient's vision.
In addition to routine visual acuity chart examination, there are some more sophisticated visual acuity examination items, such as refractive examination, slit lamp examination and corneal topography. These projects can help doctors understand patients' vision problems in more detail and provide reference for subsequent treatment.
2. Fundus examination
Fundus examination is one of the important means to evaluate the eye health of patients with high myopia. Fundus examination can judge whether there is retinal or optic neuropathy by observing the blood vessels and structures inside the fundus. For patients with high myopia, due to the abnormal shape of the eyeball, it is easy to lead to stretching and thinning of the fundus, increasing the risk of retinal detachment or rupture.
In fundus examination, doctors usually use professional fundus cameras or fundus microscopes to observe fundus conditions. These devices can magnify the details of the fundus and help doctors accurately assess the health of the patient's retina and optic nerve.
3. Corneal topography examination
Corneal topography is an important examination to evaluate the surface shape and curvature of the cornea. For patients with high myopia, the curvature of the cornea will also be affected due to the abnormal shape of the eyeball. Corneal topography can help doctors understand the state of the patient's cornea and judge whether it is suitable for myopia surgery or keratoplasty.
In corneal topography examination, doctors will use special instruments to measure the curvature of the cornea for patients and generate corneal topography. By analyzing these data, doctors can determine the degree of myopia and the shape of the cornea. This information has an important guiding role in selecting appropriate methods for myopia correction.
4. Wave front technical inspection
Wavefront technique is an advanced ophthalmic examination method, which can comprehensively evaluate the optical abnormalities of patients' eyes. For patients with high myopia, due to the abnormal shape of the eye, the optical system of the eye will also change, resulting in a decline in visual quality. Wavefront technology inspection can accurately measure the abnormalities of the optical system of the eye, and help doctors develop personalized treatment plans.
In wavefront technology examination, patients need to focus on specific images, and the instrument will scan the eyeball through the laser beam and record the propagation information of light. By analyzing these data, doctors can obtain detailed information about the optical system of the eye, and evaluate the degree of myopia, astigmatism and the imaging quality of the eye.
Summary
Eye hospitals in Guangzhou and Shenzhen provide a variety of eye examinations to assess the eye condition of patients with high myopia. These items include visual acuity examination, fundus examination, corneal topography examination and wavefront technique examination. Through these examinations, doctors can fully understand the patient's eye health, and provide reference for correcting myopia and treating eye diseases.
